Lincoln Loud/Relationships

This page describes all of Lincoln Loud's relationships with his family and friends.

His sisters generally
Despite the chaotic and stressful antics from his sisters, he loves them deeply, and really cares for them. For the most part, he has fun being a part of their chaos, and doesn't mind being the only boy.

He is rather protective of his family, as he resolves conflicts between his sisters, younger and older, but they all get annoyed with him if he does something like flat out ignore them. In "Sound of Silence", since they all have an equally tough time finding quiet time in their home, they would then show him the consequences as payback, but they receive punishment as well. Like all families, they would all rush straight to his aid if he were being bullied, and are very supportive of his romantic life, so they all really want the best for their only brother. They always try to help him through his issues, but are usually incompetent in doing so, but always insist on it unaware, much to his frustration.

In "Heavy Meddle", it was revealed that his sisters have a tendency to meddle in his affairs when he doesn't want them to, and believes they'll make everything worse. An example was when they all took care of him when they thought he was sick, but all he had was a paper cut. They also wanted to help him with his bully problem, showing that they don't want anyone bullying him (because they're the only ones who can bully Lincoln) and tend to give him some bad advice on how to take care of it. They also enticed him to kiss his bully when they found out it was a girl. Lincoln got fed up with them after she punched him for kissing her and told them never to meddle in his life again.

In "Chore and Peace", Lincoln was done of always being the one taking the trash out and the sibling with the most hard chore so he asked his sisters to swap chores with him but they refuse, saying there's a "very delicate balance" in the house. Lincoln, frustrated, goes on strike until he gets what he wants. The girls also decide to go on strike until Lincoln ends his but Lincoln still refuses to back down. He (and his sisters) only end their strike when they realized that Lily was missing from her crib. The siblings worked together to clean up the whole house only to see that their parents had Lily the whole time.

They are all always there for him when he needs support and/or help and vice versa, as seen in "Cover Girls", where they cover for him to stop him getting into trouble with their parents and "Project Loud House", where they step in with their physical bodies to replace his broken homework model of them. However, they are sometimes incompetent in this as well, like in "House Music", when they forgot to untie him.

Sometimes, Lincoln thinks he is tired of his sisters' antics, only to find he quickly gets lonely without them, as shown in "Linc or Swim".

However, he hardly finds time for himself, and blames the sisters for this, because he must be with them in all of their activities. In "No Such Luck", he pretends to be unlucky after allegations from Lynn that he's bad luck, but this gets blown out of proportions, and it leads to Lincoln being in a very bad situation.

They even know how important some matters mean to him, as featured in "Pulp Friction", where they all work together to get him and Clyde out of detention so they can get to the post office and mail in their comic book entry on time, as well as get it back after it's been confiscated. Lincoln based the characters who save Ace and Jack from Wild Card Willy's clutches on his sisters, showing that they always have his back.

In "Yes Man", they ask Lincoln for advice in how to convince their parents to give them money. But because of this, he couldn't get the money he needed for a ticket to the VIP SMOOCH concert because the parents gave all their money to the sisters. So they all make it up to him by organizing a concert of their own in front of their house, and even convinced SMOOCH to perform with them.

He's close to Leni Luna Lucy Lana and Lily out of all his sisters

Lori
Lori is often very mean, bossy, and/or nasty towards him, and at times, seems to be the sister he has the worst relationship with (alongside Lynn, and occasionally Lola). Like his other siblings, he detests when she's too bossy to them, but she deeply loves him, although she doesn't admit it.

In the pilot, she deliberately cuts in front of him to use the bathroom when he really has to go. Lincoln chases Lori out of the bathroom with one of Lily's dirty diapers so he can meet with his "pressing engagement".

In "Get the Message", she furiously berates Lincoln for entering her room by mistake, and angrily warns him to stay out of her room, or she will turn him into a human pretzel, if she sees him in there again. Later, Lori accidentally breaks Lincoln's video game, and doesn't initially apologize. This leads Lincoln to write a hateful letter to her, and send her a nasty message. However, she unexpectedly bought him a new copy of the destroyed game, and apologizes (though, in a seemingly phony way) for destroying the first one, which she states was very mature of Lincoln for not freaking out over it. She later erases the message herself, and berates him for calling her phone, despite not hearing the full message. Although she gave Lincoln a pass on this, Lori found the written letter about her in the bathroom, and becomes enraged towards Lincoln. Lori's nastiness to Lincoln throughout the story makes it difficult to decipher just how sincere her apology was to him, as it seemed that she simply did not want to be bothered by him on that day.

In "No Guts, No Glori", he stages an uprising to end Lori's tyrannical babysitting methods while their parents are out. However, when the other sisters trash the house, he apologizes to her and she gets the sisters to clean up before the parents come home, showing that when the two get along, they can make a pretty good team.

In "Driving Miss Hazy", she forces favors from him and the rest of her siblings in exchange for rides around town, forcing Lincoln to do her laundry.

In "The Sweet Spot", Lori throws up on Lincoln during a car trip.

In "Sound of Silence", she joins in with pranking Lincoln, using him as a footstool while painting her toenails, but she went tone deaf due to the explosion in Lisa's room at the end.

In "Hand-Me-Downer", Lori hands her bike down to Lincoln. However, Lincoln was ashamed of it.

In "Cover Girls", at certain points, Lincoln imitates Lori, and the latter dresses up like the former.

In "Save the Date", Lori becomes very angry and violent to Lincoln, as she threw numerous things at him. She explained that Bobby broke up with her, due to Lincoln making Bobby's sister Ronnie Anne cry over his harsh comments about her. Lori then forced Lincoln to go on a double date with Ronnie Anne and make her feel like the most special girl in the world, so Bobby could get back together with Lori.

Despite the above, within the first season, she can be friendly towards Lincoln when she wants to be.

In "Out on a Limo", she kindly suggests for Lincoln to enjoy the limo ride himself for a while before the rest of them all go for a ride in it.

In "A Novel Idea", she was the first to give her sympathies towards Lincoln, when she thinks that he had a boring day while she and the other sisters had a good time.

Their relationship comes into focus again in "A Fair to Remember", where Lori encourages Lincoln to go to a monster truck rally with Bobby as she was not interested in going. When the two become close, Lori becomes jealous as Bobby starts paying more attention to Lincoln, going so far as to "date" Clyde in retaliation. Lincoln sees how much Lori feels neglected, and convinces Bobby to spend more time with her. Lori thanks Lincoln and agrees with Bobby that Lincoln really is a "great bro".

In "Ties That Bind", when Lincoln mistakenly believed he was to be kicked out of the house, Lori refused to let this happen and immediately led the siblings in confronting their parents on this misunderstanding.

In "The Waiting Game", the entire story centers around their relationship. After Lincoln informs Lori about a job opening so she can earn enough money for a dress for a school dance, she offers him free root beers and pizza for him and his friend Clyde. However as the episode goes on, Lincoln begins to take advantage of her to get whatever he needs to impress his classmate Chandler in order to get invited to his birthday party, even going as far as to guilt-trip her into giving into his requests. Near the end of the episode, Lori tells Lincoln that thanks to him she has to work overtime to pay off all the free stuff, and won't able to go to the dance with Bobby and sarcastically (but not maliciously) "thanks" him in a sad tone. Now realizing his mistake, Lincoln explains what happened to Lori's boss, and he offers Lori a deal that she can go to the dance, and Lincoln fills in for her. She thanks him at the end of the episode, and they hug before she leaves for the dance with Bobby. She even gives Lincoln sympathy for having to miss Chandler's party.

In "The Whole Picture", it is revealed that Lori was the first who fed Lincoln ice cream, and she used to swing him as a toddler.

In "No Such Luck", she tried to go and play golf with Lincoln, not believing he brings bad luck, but he intentionally destroyed her golf stuff to prevent her from bringing him along.

In "The Loudest Mission: Relative Chaos", they team up to get their love interests back (Bobby and Ronnie Anne, respectively) due to them moving away.

In "Health Kicked", Lori allowed Lincoln to hang onto her while she, and her other siblings, hold onto a hanging beam with their parents at the "Royal Woods Ultra Extreme Ninja Competition".

In "Not a Loud", she tells Lincoln some details about his birth.

Leni
Leni's ignorance and naivety often causes annoying occurrences for Lincoln, but he tolerates it, because of her kind and friendly nature, making them have one of the closest relationships of the siblings. Alongside Luna, his relationship with her is the best among his older sisters.

In "Driving Miss Hazy", he helped her to get her driver's license, by using her semi-language, knowing that, unlike Lori, she wouldn't demand chores done in exchange. He also convinced her to not give up trying, but she ultimately fails, thanks to Lori.

Leni is the sister Lincoln decides he would like to sit next to in "The Sweet Spot".

In "Along Came a Sister", Lincoln brought his classes' pet tarantula home for the weekend, and Leni tried to kill it out of fear. However, after she learned Lincoln will have big trouble in school because of the dead spider, she felt very sorry. When the spider is still alive, she protected it to save her brother's status quo, proving how much she loves her brother, and the good person she is.

In "Linc or Swim", she happily invited him to join her and the other sisters multiple times, even to a newly purchased pool, even though he was mean to her and the others for using his pool. After he accidentally destroyed their pool, he invited them all to rejoin him in his pool.

Leni gave Lincoln her t-shirt in "Hand-Me-Downer", however, Lincoln hides it under his bed.

In "Ties That Bind" and "Chore and Peace", it is shown that Leni really loves Lincoln's white hair, making their relationship even closer.

In "Roughin' It", it was revealed that sometimes Lincoln and Leni sew clothes together, and that she taught him how to keep warm.

In "Snow Bored", Lincoln and Leni joined forces to hide from Lisa in chimney. Leni also offered him to bake chestnuts.

In "One Flu Over the Loud House", Leni was disgusted by Lincoln dismissing sick sisters and often had to scold him for this. Leni was ready to sacriface her health so Lincoln could escape from infection but he wanted her to survive believing she deserves this more as she's a better person than him.

In "No Such Luck", when Leni wants to invite Lincoln to her activity, Lynn interferes and tells Leni not to bring Lincoln, since he's "bad luck", this causes Lincoln to get an idea: he convinces Leni that his presence might cause something to go wrong, and Leni immediately believes him.

In "Change of Heart", Lincoln asked Leni to teach Clyde to act normally around Lori. They all three played video games together.

In "Not a Loud", she tells Lincoln some details about the day he was born.

Luna
Because Luna is very nice and helpful towards everyone, Lincoln seems to tolerate her the most and they have one of the closest relationship of the siblings. She sings songs for him to make him feel better or to motivate him to do hard things. Alongside Leni, his relationship with her is the best among his older sisters, and she also seems to be the most empathetic towards him, like in "Picture Perfect", putting his bossiness down to him changing because of the desire to get a perfect picture of them all.

However, she is not above following suit when his other sisters get angry with him, or having inconsiderate moments with him, such as in "The Sweet Spot", "Sleuth or Consequences", or "Making the Grade", as well as showing smugness towards him for the Princess Pony reveal. In "It's a Loud, Loud, Loud, Loud, House", she kicks him out of her room by blasting her guitar strings through powerful amps at him, just out of competition among all of the Loud kids to find the money. This is very nasty by her standards, while it would be more expected from someone else like Lynn, she also think there was something missing in the letter, she and the other sisters violently attacked Lincoln, but they all made up at the end. Despite all of this though, she is one of his kindest sisters, and deeply loves him.

In "Ties That Bind", after Luna interpreted that she makes Rita's ears bleed, she felt sad because of the harsh reception. Lincoln and Luan patted Luna on the shoulders to make her feel a bit better.

In "Hand-Me-Downer", Luna gave Lincoln her old, but broken guitar.

Probably most importantly, in "For Bros About to Rock", she wanted to make his first concert very unforgettable. He brutally admitted he doesn't want her to ruin his first concert as she had already done to Lori, Lana, Lola and Lisa. She felt hurt but realized he's correct about her. After Lincoln was arrested for attempted illegal purchasing of concert tickets, Luna disguised herself as their mom to get him free so they and Clyde could go to the concert. At the end, they all enjoyed the concert together.

In "Cover Girls", he dresses up as her at one point.

In "Roughin' It", it is revealed that she taught him how to knit.

In "The Loudest Yard", Luna was so excited about Lincoln becoming a football star, she volunteered to play the national anthem on her brother's big match.

In "Kick the Bucket List", Lincoln was playing a one-man band instrument. Luna saw this and offered to join him, and was disappointed when he refused.

In "Garage Banned", Luna accidentally damaged Luan's puppet Mr. Coconuts. When Lincoln told Luna to pay for the damages, she threatened him with her fists.

In "Future Tense", when Lincoln was reading a comic and Luna was playing on her guitar, they were sitting next to each other.

In "Yes Man", Luna turned to Lincoln for help in how to convince their parents to give her the money she needed to buy the auctioned Mick Swagger tour shirt. After giving her advice, she sings a song that convinces them to give her the money, and then she sings thank you to her brother. Later, when he has trouble convincing their parents to give him the money he needs to buy a SMOOCH ticket, he asks Luna if he can borrow her guitar, which she flat out refuses to, only to reveal that she was only messing with him, and lets him borrow it.

In "Not a Loud", Luna tells Lincoln some details about the day he was born.

Luan
Like all of his sisters he gets annoyed by Luan's funny and/or terrible jokes. She can at times pull nasty pranks on him, but this is likely due to the fact that she is trying to be funny, and isn't really aware that what she did can cause him grief, so it appears that she does it without malicious intentions.

In "Making the Case", he came to her for advice on making funny viral videos, and she happily gave him the idea to always have the camera on. After he humiliated all his sisters, Luan was the only one who had any desire to speak with him. She gave him advice how to fix his relationship with his sisters which later worked at the end.

When he thought he was going to be expelled from his family in "Ties That Bind", he left her his comic book collection, but she refused them as she didn't want him to leave.

Luan gave Lincoln her old ventriloquist dummy in "Hand-Me-Downer", and said she won't forgive him if he loses it.

In "Cover Girls", Luan was very worried when Lincoln got hurt, while the latter is trying to get into his room. Also, in the same episode he dresses up as Luan while covering for her, when she was at a birthday party performing.

In "April Fools Rules", she used Lincoln's feelings to Ronnie Anne to manipulate her brother and make him fall victim of her hurting pranks. She had an unhealthy satisfaction of completing her plan. However, this backfires on Luan, as Ronnie Anne was touched by Lincoln doing such at thing for her and pelts Luan with a pie at her face as retribution.

In "Funny Business", Luan offers Lincoln the position of her clown assistance. He later begins to hog the attention when he accidentally causes kids to laugh, and he loves it so much. He and Luan have a falling out, but after they eventually make up, the two have become closer siblings after this experience.

In "Fool's Paradise", she tricked him and the rest of the family that they sent her to clown camp on April Fool's day and rigged the motel they were staying at full of pranks. After discovering his father was an accomplice in her scheme, he works with his family to prank Luan back.

In "Garage Banned", Luna accidentally damaged Luan's puppet Mr. Coconuts. When Lincoln told Luan to accept Luna's refusal to pay, Luan threatened Lincoln with Mr. Coconuts.

In "Not a Loud", she tells Lincoln some details about his birth, and tells him that she was excited to finally have a brother.

Lynn
His relationship with her is quite complex. She constantly roughhouses with him, thinking it as playful, like in "The Sweet Spot", and often doesn't stop to acknowledge when this leaves him wounded at the price of her amusement. She likely picked him as her sparring partner, because he's the closest to her in strength and fitness.

In "Making the Case", she prepared to beat Lincoln up for uploading videos involving her and their sisters, however this changed after Lincoln embarrassed himself to fix his relationship with his sisters including Lynn.

In "Space Invader", after she had a heated argument with Lucy, Lincoln was the first person she asked to share rooms, using puppy eyes to convince him. He couldn't endure her roughhousing, her pranks and especially her snoring. Having too much heart to just kick her out, he replicates her assaults to attack her, but she shows only enjoyment for this, possibly implying that she really just wants someone to fight back against her. Then he decided to restore peace between her and Lucy which worked well.

In "Hand-Me-Downer", she was angry at him for stealing her bike and losing it, so she took his bike to the race. However, after she won the race and he found the bike, she allowed him to keep it.

In "April Fools Rules", when Lincoln decides to take on Luan's pranks, Lynn worried for his safety.

In "The Loudest Yard", Lincoln was assigned by their mom to a football team and Lynn offered him to teach him how to play. She tried to train him but it was hard due to his laziness, much to her annoyance. Later Lynn agreed to impersonate Lincoln during his football matches. When Lynn got hurt during the second half of the game, Lincoln expressed his concern by asking Lynn if she was okay, which she replied that she was fine, but may have sprained her ankle.

In "Cheater by the Dozen", Lynn pulls Lincoln by his t-shirt which forces to tell her and their other sisters (except Lori) about her boyfriend Bobby cheating on Lori.

In "No Such Luck", Lynn needed and forced Lincoln to come and support her at her baseball game. After Lynn's team loses, Lynn declares Lincoln as "bad luck" as she tells Lincoln that her whole team had a wining streak until the one time Lincoln comes to the game and they end up losing. Eventually, Lincoln disguised himself as the mascot of the Squirrels and after Lynn manages to win for her team, Lincoln revealed himself to his family. Lynn apologizes to Lincoln as their family gathers around him.

Despite the above, the two can spar with each other on friendly terms, as in "Ties That Bind", Lincoln appears to willingly be playing with Lynn as he was trying to compete with her at parkour.

When Lincoln is being bullied, Lynn is the perfect one to rush to his aid and train him against them.

In "Future Tense", Lincoln and Lynn teamed up to go from house to house to ask people for voting.

Lucy
They don't share the same interests, but they get along well with each other, though Lincoln hates it when Lucy scares him. Lucy sometimes asks him for help to create rhymes for her poems. Despite her "spooky" personality, Lincoln seems to appreciate her and he tolerates her creepy hobby and she's glad for his tolerance. So, they share a close bond, having the closest relationship of the youngest siblings. In many episodes, she comes to Lincoln to ask him for proper rhyming words.

She and Lincoln are so close that she's eager to tell him about her bad dreams as shown in "Sound of Silence".

In "Sleuth or Consequences", she clogged the toilet which leads to Lincoln being wrongfully accused. She tried to help him clear his name so he could go to the comic book convention, but also tried to frame her other sisters. When Lincoln discovered she's guilty, he was angry at her for lying to him and wasting his time. She begged him not to tell anyone in order to save herself from humiliation for the rest of her life, and he took the blame himself. She was grateful to him so she showed her appreciation for it by giving him her homemade horror comic, which he accepted with pleasure.

In "Space Invader", during the food fight, Lincoln accidentally threw a meatball at Lucy when he was targeting Lynn. Lucy didn't mind it, because he didn't do it on purpose, but Lynn's laughing bothered her more, and so then she threw meatball at Lynn, and sarcastically laughed. Because the sisters' room was too dirty to sleep there, they both asked Lincoln to let them sleep in his room, and he agreed to the offer.

In "Changing the Baby" he invited her to play in ghost hunting, but she refused by explaining they are her friends.

In "Roughin' It", it's revealed Lincoln gives her manicure much to her joy due to her messing up right hand.

In "Suite and Sour", Lincoln and Lucy search for a ghost together.

In "Back in Black", Lucy scared Lincoln, and caused a mess, but she helped him to clean it up. Lincoln was sympathetic to Lucy's crush on Rocky, so he helped her get together with him. He told her his impression of Rocky and gave them the opportunity to meet again by destroying his project he worked on with Rusty, so the two would be forced to work on it again at Lincoln's house, so that Rocky could also come over.

In "Out of the Picture", Lucy agreed to let Lincoln pretend to be a member of the Morticians Club, so he could have a photo for the yearbook.

In "Spell It Out", Lincoln is the first sibling who apologized to Lucy for ignoring her.

According to his vlogs, Lincoln considers Lucy as his closest sister, at least in a distance.

Lana
Lincoln's the one who typically breaks up fights and arguments between Lana and her twin, Lola, and he promised to protect them from ghosts during "Left in the Dark". While Lana loves gross things and isn't that picky when it comes to her eating habits, but even she found Lincoln peanut butter-and-sauerkraut sandwich to be gross. She's close enough to Lincoln to introduce him her new pets, and for the most part the two seem to get along okay.

She once took the remote control to scratch her back, Lincoln agreed to scratch her back if she gives him the remote control back.

In "Hand-Me-Downer", he gave her his newest bike, much to her joy.

In "Toads and Tiaras", Lincoln wanted tickets to Dairyland so much he convinced Lana to impersonate Lola to compete in a beauty contest to win them. Much to her annoyance, he tried to make her act not like herself but he constantly reminded her about Dairyland. However, after seeing how much she suffered not being herself he apologized to her and told her to be herself even if she doesn't win the contest, but to their excitement, they win the tickets.

In "Cover Girls", he dresses up as Lana and Lola (both at the same time). Lana laughs from his disguise but he remains calm due to critical situation and simply tells Lana to get dressed as Leni.

In "Frog Wild", he teams up with Lana to save the dissecting frogs after she convinces him it's wrong. After they've rescued the frogs, the duo then hides them from Principal Huggins after he checks every house for them. However, they were caught, but to their joy, Mrs. Johnson, who's in tears after seeing Lana's backstory about Hops, refuses to dissect them and gives them a nice home. Unfortunately, Lincoln ends up getting detention, which Lana apologizes to him for.

In "Lost Control", she once took the remote control to scratch her back; Lincoln agreed to scratch her back if she gives him the remote control back.

Lola
Lincoln and Lola may have situations with each other, but deep down, they care for each other. Lola often blames him for many bad things that happen to her even if she can blame only herself like in "Chore and Peace" and "It's a Loud, Loud, Loud, Loud, House" and he rivals him like Lana very much. Because of her selfishness to Lincoln (and sometimes Lana), they have the worst relationship out of all the siblings. He's afraid of Lola's anger, and she can easily take advantage of him, since their parents are more likely to believe the younger one, and in "Toads and Tiaras", it is shown that he helps Lola prepare for her beauty pageants and that her wrath is so huge that both Lincoln and Lana, both older than her, fear it. She was his main opponent in "Undie Pressure". He lost the bet and abandoned his habit as a part of the deal, but Lola felt sorry for him and bought him comfortable slips, showing her soft side; he hugged her in return.

Lola is always grateful towards Lincoln when he does nice things for her. She is selfish and likes to inconsiderately paint his nails and put makeups on his face as seen in "The Sweet Spot" and "Overnight Success", but he tolerates this and takes it well. In "Cover Girls", he dresses up as Lola and Lana (both at the time) at one point while covering for them.

In "Out of the Picture", when Lola gets a very bad yearbook photo, her pageant career will be over. She then asks the sisters for help. Unfortunately, they were no help (Leni believed that her phone can only take photos of herself, Luan's camera ends up being another one of her pranks, and Lisa scans Lola's x-ray). Lily ends up taking a perfect photo of Lola. Luckily, Lola turns to Lincoln and changes her photo. Lola was grateful by this and says she'll never forget this.

In "Future Tense", Lincoln and Lola teamed up to clean the streets of rubbish from Royal Woods to.

In "Read Aloud", Lincoln helps Lola to learn how to read, and when Lincoln was going to take the blame for the family losing the reading contest, Lola didn't want her brother to go through this, and tells the family that it was because it's hard for her to learn how to read, and that's why it took so long for her to read a book.

Lisa
Lisa considers him and the rest of the sisters, as not very intelligent. Lincoln doesn't have a lot of interactions with her, but the two don't seem to have many problems with each other, a part from Lisa's sometimes harmful experiments. He gets disgusted, annoyed or down right terrified when she tries to use him or the other sisters as test subjects for her experiments, like in "Project Loud House", after she turns Leni's skin blue, or putting Lily into a mad scientist's like machine in "Changing the Baby".

In "Butterfly Effect", Lincoln breaks Lisa's chemical bottles with his yo-yo and he believes Lisa will get angry for what he did, but instead of being angry she becomes ecstatic with him and thanks him for prove her hypothesis and for admitting what he did.

In "Baby Steps", it was shown that Lisa enjoys the peanut butter and jelly sandwiches Lincoln makes for her.

In "Making the Grade", Lisa gets prompted from kindergarten to the fifth grade after finding kindergarten too easy. Her smartness makes Lincoln an outcast and he tells Lisa to tone it down. Then Lisa's new personality made her become relatively popular. However, this cause issues at home because Lisa refuses to help her family solve things that the others cannot and their other sisters (except Lily) take their anger out on Lincoln.

In "The Whole Picture", it was revealed that Lincoln used to feed her with milk.

In "Garage Banned", Lisa harvested Lincoln's appendix and tried to harvest his kidney against his will.

Lily
He and Lily really love each other. Lincoln is one of the siblings who often carries Lily (along with Lori, Leni, and Luna), changes her diapers, and burps her. Lincoln lets Lily play with his favorite plushy Bun-Bun, as seen in "Heavy Meddle".

He tries to implement his interests on his baby sister, because he had nobody to play with in the episode "Changing the Baby". He's very protective towards her, as he saved her from falling, searched for her when she was missing, and saved her from Lisa's seemingly dangerous experiment.

In "Two Boys and a Baby", he babysat her, and learned it isn't as easy as he thought, which is strange, as in other episodes he hasn't had problems looking after her.

In "Cover Girls", Lincoln dresses up as Lily at one point.

In "Baby Steps", it was shown how he gives Lily his care if she gets hurt.

In "No Such Luck", Lily said Lincoln's name while he was trying to sneak away from their sisters.

In "Room With a Feud", Lincoln and Lily become roommates which the former has trouble adjusting to because of the latter's noise and smelly diaper.

In "Potty Mouth", Lincoln accidentally swears in front of Lily after he accidentally busted the TV with a video game motion controller.

His parents generally
Lincoln also loves his parents and they love him too. Every time he wants to do something he must ask them for permission like in "In Tents Debate", where he asks them if they can go to another place for their annual vacation. In "Ties That Bind", Lincoln believes that his parents want to get rid of him and his sisters, but it was just a misunderstanding. They seem to not favor any of their children to prevent harder sibling rivalry.

In "No Such Luck", Lincoln pretended he brings bad luck, and it worked so well his parents believed it and kicked Lincoln out the house because they were scared that his bad luck could hurt any member of their family, and sold his furniture.

In "Future Tense", both parents were concerned about Lincoln's future, but they just forced him to read educational comics instead of going on extracurricular activities like the rest of the sisters (minus Lily).

In "Not a Loud", it is revealed that Lincoln was born in a limousine which belonged to the president of United States, and signed an agreement saying that they would never discuss it.

Rita
He seems to be closer to his mother than his father. In "A Novel Idea", Rita felt sorry for Lincoln when Lynn Sr. only takes the girls to his workplace for "Take Your Daughter to Work" day, and decides to take him to her workplace; a dentist office. He tried to make the most of it, but fails. He accidentally lost his mother's journal while he at an arcade, and he goes on a wild goose chase and retrieve the book back. Unfortunately, her book disintegrated, she was angry at first, but he done a favor for her since she realized the book she wrote had a very boring plot. Then she decided to write a new book about Lincoln, he was overjoyed and the two hug. After the girls got home, they saw them on roller skates being pulled by a horse, much to the girls astonishment.

In "The Loudest Yard", Rita couldn't bear Lincoln's lazy lifestyle. She tried to convince him to do some exercises instead of reading comics and playing video games. After she discovered he doesn't take it seriously, she assigned him to play in a football team to force him to be more active. Rita was furious at Lincoln when she discovered he persuaded Lynn Jr. to impersonate him during his football matches.

In "Kick the Bucket List", she gives Lincoln a blanket to keep himself warm as he gets some sleep from working on shortening his list and reminds him to be back home before dark since he has to go to school the next day.

Lynn Sr.
In "Sleuth or Consequences", Lynn Sr. and the girls (except Lucy) blamed him for clogging the toilet since he always have a habit of doing it a lot. But it turns out that it was Lucy who clog the toilet, and Lincoln takes blame for Lucy (to save her from being embarrassed) and gets grounded.

In "The Loudest Yard", Lynn Sr. tried to do jogging with Lincoln. He was angry when he discovered he prefers playing arcade. Rita assigned Lincoln to football team and he convinced Lynn Jr. to impersonate him. Lynn Sr. was proud of his son as a football star but get devastated when he discovered it was false.

In "The Whole Picture", it is revealed that he taught Lincoln how to ride a bike.

In "Spell It Out", Lynn Sr. comforts Lincoln while Rusty gets killed in an online game.

In "Fool's Paradise", Lynn Sr. and Lincoln worked together to prank Luan back after she was pranking the rest of their family.

In “Legends”, Lincoln and Lynn Sr. compete in a game show.

Albert
Lincoln is quite close to his maternal grandfather. He greeted him with hug when they met in person. They both like having fun with each other. They both tried to jump into the pool and playing twister. In the past they also played in the forest.

Clyde
Clyde is Lincoln's best friend and wingman, and both have a good relationship. Clyde appears to be Lincoln's only male friend, as he is the only boy of his school class that tolerates his sisters' antics.

Clyde is very loyal to him and when Lincoln gets a plan, he is always prepared to help him. They usually hang out in other places, or just spend time with Lincoln's sisters. The only thing that annoys Lincoln from Clyde is his obsession with his sister Lori. In "Changing the Baby", Clyde feels sad after thinking Lincoln has replaced him with Lily, but at the end Lincoln says him that he won't be replaced because he is his best friend. He also came with him to SMOOCH concert in "For Bros About to Rock".

Although, the Loud sisters can get in the way, Lincoln and Clyde love watching TV together, as seen in "Left in the Dark" and "Cover Girls". It is shown in "Sleuth or Consequences" that the two boys like to cosplay as Ace Savvy and One-Eyed Jack together.

Howard and Harold
Lincoln has a good relationship with Clyde's dads. He admires the amount of time they spend helping Clyde, and somewhat envies the amount of attention they give their son. In "Attention Deficit", Howard and Harold try to help Lincoln with his school project. Lincoln's sisters end up hogging their attention, but Lincoln is not mad at them.

Lincoln normally addresses both Howard and Harold as Mr. McBride. He has also called Howard "Mr. McB."

Ronnie Anne
Ronnie Anne is Lincoln's other best friend and former love interest. He is initially bothered by her bullying him in "Heavy Meddle", but after she sends a note apologizing to him, Lincoln begins to see that she may not be such a bad person after all.

In "Save the Date", Lincoln tells a few kids at school that he would rather lick the bathroom floor than kiss Ronnie Anne, but only to hide their relationship. Unfortunately, Ronnie Anne overhears him saying this and is heartbroken about it, which makes Bobby break up with Lori. Lori then forces Lincoln to make it up to Ronnie and fix her relationship by going on a double date with Bobby and Ronnie Anne. While Ronnie is still mad at him at first, she understands his conflict with Lori, stating that she has similar problems with Bobby. Near the end, Lincoln kisses her in front of his classmates. The next day, Ronnie Anne once again hides their relationship by slapping him in the face and seemingly breaking up with him, which she soon reveals to be fake via note. It is believed that they are on really good terms.

In "April Fools Rules", Ronnie Anne is coming over on April Fool's Day, the day Luan becomes a pranking monster and sets up cruel pranks around the house. To protect her, Lincoln sacrifices himself and ends up setting off all the pranks, causing severe injury to himself. Ronnie Anne then comes to the house and throws a pie at Luan and offers to draw eyebrows on Lincoln and invites him for a milkshake, saying she was grateful for him protecting her from Luan's pranks and the two head off on their way.

In "Dance Dance Resolution", Lincoln ducks from Ronnie Anne to ensure she doesn't ask him to the Sadie Hawkin's Dance, not because he doesn't like her, but rather because he wanted to go to the arcade instead. When Luan, Lucy, Lynn, and Luna each get him a date to the dance, and he sees Ronnie Anne is at the dance as well, he tries to avoid her because he feels he will hurt her feelings if she finds out he went to the dance without her. When she finds him, she states that she actually never wanted to ask him to the dance but rather to go to the arcade with her. Upon learning he was avoiding her all day, she forgives him, she admitting she would've done the same if he were to ask her to a dance. The two are then seen together at the arcade, playing Dance Battle.

In "Shell Shock", Mrs. Johnson assigns Lincoln and Ronnie Anne to take care of an egg as a school project. Lincoln is afraid that Ronnie Anne is too reckless to take care of an egg so he tries to not let her take it. When Ronnie Anne says she's going to take the egg home at the end of the day, Lincoln makees a complete replica of the egg from rubber cement and gives it to her. She is surprised by his sudden change in attitude. However, Lincoln soon finds that he actually gave Ronnie Anne the real egg instead of the fake egg, so he goes to her house, telling her he just wanted to see the egg. Just after Lincoln switches the eggs, he notices that Ronnie Anne is a really thoughtful and helpful person at her house. Realizing that Ronnie Anne is not as reckless as he thought, Lincoln decides to put the real egg back, but Ronnie Anne catches him trying to replace the eggs and is furious when he tells her he didn't think he could trust her to take care of something so fragile. During this, Lincoln himself accidentally causes the real egg to fall and break. Heartbroken at the fact that they're going to flunk the assignment, and at how Lincoln perceives her, Ronnie Anne tells Lincoln to leave her house. Sometime later, Lincoln comes back to the Santiago house with a replacement egg. He explains that he talked with Mrs. Johnson to give Ronnie Anne a second chance on the assignment, because he learned that she's not as bad as he thought. The teacher agreed, but they won't be rewarded with the big waffle breakfast, but Lincoln says he no longer cares about that, just as long as he and Ronnie Anne can get the assignment done. Ronnie Anne, grateful for what Lincoln did, invites him inside, since they're having waffles for breakfast. Then Ronnie Anne tricks Lincoln into thinking she's going to break the replacement egg as a revenge.

Bobby
Lincoln is pals with Bobby, as shown in the episode "A Fair to Remember", after Lori tells Bobby to hang with Lincoln instead of her. At the end of the day, Lincoln and Bobby became friends. They seem to regard each other as "bros", both seeing the other as the brother they never had.

Casagrande Family
Generally, Lincoln gets along well with the Casagrande Family and relates to them as he also comes from a huge family. He appeared to have really enjoyed what little time he spent with them, though he was embarrassed by them referring to him as Ronnie Anne's boyfriend. While both Lori was trying to convince Bobby to leave, Lincoln spent his time hanging out with the Casagrandes, playing with CJ and helping Rosa Casagrande with her cooking.

Carlos Jr Casagrande
Despite Carlos Jr's disability, the two became fast friends, with Lincoln treating Carlos almost like he would a younger sibling. He loved playing childish games like "Pirates" with him and truly enjoyed his company. Later, the pair would help repel the incoming homeless cats by playing Pirates once again.

Rosa Casagrande
Rosa, like the rest of the Casagrande family believe Lincoln to be Ronnie Anne's boyfriend, much to his chagrin, though despite that, Lincoln gets along well with Rosa. When Lincoln arrives to the Casagrande residence, Rosa happily offers to cook for Lincoln, assuming he must be hungry, to which Lincoln takes the offer. After the meal, Lincoln is suffering from a stomach ache, and Rosa uses her special technique to make him feel better. Later on, Lincoln offers to help Rosa cook.

Agnes Johnson
Lincoln is one of Mrs. Johnson's most dedicated students. Whenever she gives him an assignment, he does his best to follow through with it rather than slack off and procrastinate like most kids, even if at times, it doesn't work out.

In "Project Loud House", she originally planned to give Lincoln an "A" on his report about his sisters, but thanks to Luan's bucket prank, she downgraded it to an "A-".

In "The Green House", she, along with the rest of the class, disciplines Lincoln for not being able to save enough energy to help them win a contest to name a polar bear, which cannot be helped because of his big family. However, when he finally manages to do his part, she congratulates him for leading them to victory.

In "Along Came a Sister", she chooses him to look after the class pet tarantula Frances over the weekend, showing that she can trust him.

In "Dance, Dance Resolution", she holds a raffle where the winner has lunch with her in the teacher's lounge, and he wins that prize. She also unknowingly bumps him with her butt when he's trying to avoid Ronnie Anne.

In "Study Muffin", she broke her leg from a mechanical bull incident, and hired Ms. DiMartino to substitute her class while she recovered. When she returned, Lincoln unintentionally commented on how beautiful Agnes was when he meant Ms. DiMartino, and she was so flattered by his words that she invited him to sit in the front row.

In "Shell Shock", Mrs. Johnson pairs Lincoln and Ronnie Anne to an assignment of taking care of an egg. Lincoln accidentally breaks the egg, so he came to his teacher to ask for a second chance for Ronnie Anne. Mrs. Johnson agreed for giving her another egg so she could pass the assignment, but with no reward. She also decided to give Lincoln a second chance as well so both Lincoln and Ronnie Anne could complete the assignment together.

Rusty Spokes
Rusty Spokes is one of Lincoln's friends and classmates.

They first met in "Hand-Me-Downer". Rusty mocked Lincoln's pink bike, but accepted him as a member of his bike gang when he made him believe he has a cool BMX. When Lincoln revealed the truth, Rusty and the other bikers kicked him out of their gang. Because of this, he at first appears to be one of the mean kids, but in later episodes, he is seen as a more sympathetic character, and he and Lincoln seem to get along just fine.

In "Lincoln Loud: Girl Guru", Rusty was mad at Lincoln for bad advice about his would-be girlfriend.

However, they were friends again in "Dance, Dance Resolution", and along with Clyde, Liam, and Zach, he's one of the few who knows about Lincoln's secret relationship with Ronnie Anne. He also agreed to accompany Polly Pain to the dance and became her date.

They both worked together on a science project in "Back in Black".

In "Making the Grade", Rusty turns against Lincoln because of Lisa, and refused to let him sit with him, Liam, and Zach. But later lets them sit with him at lunch after Lisa made an antidote for the sick kindergartners.

Liam
Liam is one of Lincoln's friends and classmates. They appear to be quite close friends, in "Overnight Success", Lincoln invited him over for a sleepover. In "Back Out There", Liam, along with Zach, Clyde and Rusty tried to help Lincoln get over Ronnie Anne by taking in on a night out.

Liam respects Lincoln, as he was reluctant to spy on him and instead opted to "respect his privacy", though eventually did help Clyde spy on him. He was shown to be concerned for Lincoln when he feared he wasn't getting over Ronnie Anne and tried to help him through it, even setting him up on a movie date with his cousin, Hattie.

In "Overnight Success", Liam was the first friend Lincoln invited, after he thought he can't spend his sleepover with Clyde. He enjoyed it until Lola gave him a makeover.

In "Lincoln Loud: Girl Guru", Lincoln gave Liam advice to give his girlfriend chocolate. Liam was so happy that it worked, he called Lincoln a "Girl Guru".

In "Dance Dance Resolution", Liam agreed to accompany Tabby and became her date.

In "Making the Grade", Liam turns against Lincoln because of Lisa, and refused to let him sit with him, Rusty, and Zach. However, he later lets them sit with him at lunch after Lisa made an antidote for the sick kindergartners.

In "Back Out There", Lincoln kept going to Ronnie Anne's old house, which made Liam and the boys concerned that he had "post break-up blues". To help him out, he introduced him to his cousin Hattie, who likes sci-fi movies just like him.

Zach
Zach is another one of Lincoln's good friends. Like Liam, Clyde and Rusty, Zach was concerned over Lincoln's "post break up blues" and tried to help him get over it by participating in a night out.

In "Overnight Success", Zach was the last friend Lincoln invited, after he thought he can't spend his sleepover with Clyde. He immediately left when he knew about Lincoln's sisters' antics.

In "Lincoln Loud: Girl Guru", Zach was one of Lincoln's customers, and Lincoln advised him on something based on what Lisa said by taking a chemistry class. However, this caused an explosion that ruined the girl Zach was thinking of, Kat's hair and he wanted a refund.

In "Dance, Dance Resolution", Zach agreed to accompany Giggles and became her date.

In "Making the Grade", he didn't know Lincoln was calling him a half-wit.

In "Back Out There", Lincoln kept going to Ronnie Anne's old house, which made Zach and the boys concerned that he had "post break-up blues". To help him out, he introduced him to his friend Renee who is a die hard Ace Savvy fan like him.

Tabby
Tabby agreed to go on blind date with Lincoln at the Sadie Hawkins dance party. She was excited when she met Lincoln for the first time, and encouraged him to play on imaginary instrument. He picked piano, and she accepted it. Later they were playing their air guitars. Tabby was upset at Lincoln, when she discovered he's on dates with three other girls. However, she didn't mind it for long because she found Liam.

Giggles
Giggles agreed to go on blind date with Lincoln at the Sadie Hawkins dance party. She was happy when she met Lincoln for the first time and zapped him with the old joy buzzer trick. He retaliated with the classic something-on-your-shirt nose flick joke, which she enjoyed. They later tried to see how many muffins Giggles could juggle at once. Giggles was upset at Lincoln, when she discovered he's on dates with three other girls. However, she didn't mind it for long because she found Zach.

Haiku
Haiku agreed to go on blind date with Lincoln at the Sadie Hawkins dance party. When they first met, Haiku recites to Lincoln of her sad poem. Lincoln told her an improvised poem version of Jack and Jill and Haiku was quite impressed. Lincoln showed Haiku a shadow puppetry, but she showed her more complex shadow puppetry. Haiku was upset at Lincoln, when she discovered he's on dates with three other girls. However, she didn't mind it for long because she found Clyde.

In "Out of the Picture", Haiku agreed to let Lincoln pretend to be a member of the Morticians Club to get their group photo taken. That means she still considers him as her friend.

Polly Pain
Polly Pain agreed to go on blind date with Lincoln at the Sadie Hawkins dance party. Polly first came up to Lincoln by vigorously slamming into him with a roller derby move she calls Booty Block and claiming she nailed him. She also used another move on him called the Helicopter, which involved spinning someone around really fast until they get dizzy. Lincoln was the first person she used it on not to throw up after being spun, which impressed her. She was later seen practicing more derby moves on him like tossing him across the gym. Polly was upset at Lincoln, when she discovered he's on dates with three other girls. However, she didn't mind it for long because she found Rusty.

Paige
Paige is a girl that Lincoln met at the arcade in "L is For Love". She watched him beat Clyde at air hockey, and gave him a thumbs up, in which, he was flattered by it, even though, he blushed (but Lincoln was mostly pleased about her giving him the thumbs up).

Thinking she sent him a love letter, Lincoln tried to return the favor by complimenting her dance moves on Dance Battle, but she didn't see him and unknowingly kicked him away by accident.

Later, instead of waiting for her to come to him, he went to her, and snuck a love letter in her backpack.

It is unknown when Lincoln met Paige, considering his relationship with Ronnie Anne.

Becky
Lincoln met Becky on Lori's sophisticated party in "Party Down". She enjoyed his party tricks like juggling and removing his underwear without using his hands. When she asked him for more tricks, he said "For you babushka, no problem". Together they enjoyed a wild party when Lori was finally herself.

Both Lincoln and Becky are fans of ARGGH! and both went to see ARGGH!, when it stopped in Royal Woods.

Bun-Bun
Lincoln really loves his stuffed rabbit Bun-Bun, and cares for it. He's attached to him as much as Luan is to Mr. Coconuts, or Lucy to Edwin, if not more. He claims he doesn't remember a day without him. He worries if he might get damaged by Clyde in "A Tale of Two Tables", and by Lynn in "Space Invader". In his nightmare, he was devastated when he heard he was flushed away.

In "Ties That Bind", he was ready to hand-me-down Bun-Bun to Lily, believing she'll take care of him well.

In "Not a Loud", it's revealed that he has had Bun-Bun since he was a toddler.
