"The Loudest Mission: Relative Chaos" (often shortened to just "Relative Chaos") is the twenty-fourth episode of the second season, the seventy-sixth episode, as well as the second full-length episode, of The Loud House.
Lincoln and Lori are seen leaving the Loud House in a rush. It turns out that Bobby, Ronnie Anne, and their mother, Maria, are visiting their relatives in Great Lakes City for two days. When they get to the Santiago House, Lori and Bobby continuously tell each other that they'll miss each other, while Lincoln and Ronnie Anne couldn't care any less, since they're not actually boyfriend and girlfriend. After twenty minutes of waiting for Lori and Bobby to finish, Lincoln and Ronnie Anne proceed to split the two apart, much to their despair. Once Lincoln and Lori leave, Maria arrives, and Ronnie Anne tells her that she went ahead and packed all of their stuff.
Sometime later, Bobby, Ronnie Anne and Maria arrive at the Casagrande apartment. Inside, the Casagrandes go about their day, which feature family members:
Bobby, Ronnie Anne, and Maria arrive inside, and the family members quickly greet them. As the family goes along with their day, and while Bobby and Ronnie Anne try to make themselves feel like home, Frida asks Maria if she ever told her kids the big secret yet. Maria explains to her sister-in-law that she hasn't told her kids yet, but it turns that Frida already blabbed it to at least Hector, Rosa, and CJ. Maria explains to them that she is planning on telling Bobby and Ronnie Anne, she's just waiting for the right time to do it. Maria asks them to not tell them yet, figuring that it will be best if they hear it from her.
Hector proceeds to show Bobby, Ronnie Anne, CJ, Carl, and Carlos the changes he made to the bodega, but Carlota drags Ronnie Anne away, not wanting her to visit that part of the house. Before the guys can exit the building, Hector tosses a container of fish onto the front steps, causing a swarm of homeless cats to fight over the fish. With the cats distracted, the boys make a run for it. Inside Carlota's room, Carlota presents Ronnie Anne with an outfit for her to wear, which leads to Frida snapping a photo of them. Inside the bodega, Bobby gives Hector a unique tactic on how to make some more money. Back inside the apartment, Ronnie Anne tries to get a snack, but Rosa catches her and proceeds to give Ronnie Anne a surplus of food for her to eat. When Frida, Carlota, and Rosa begin arguing on who needs Ronnie Anne most, Ronnie Anne excuses herself so she can get some time to herself. She sits on the couch, wanting to read a magazine, but the rest of the family arrives, because "The Dream Boat" is on. She then tries to get some privacy in the bathroom, but even there she is not safe from the overcrowding family.
At night, Ronnie Anne tries to get some sleep, but no matter where she sleeps, someone or something would get in the way, such as Maria rolling onto her, a passing train making a lot of noise, the black alley cats meowing loudly, Lalo taking her sleeping spot, Bobby being too noisy to sleep with, the contents of the closet falling onto her, and Sergio sleeping in the shower. Ronnie Anne's last resort is to sleep under the table.
The next day, as the family begins eating breakfast, Bobby says he's gonna miss everyone since the weekend's almost over, but CJ reveals the big secret to Bobby and Ronnie Anne. With this information revealed, Maria confesses to her kids that she's been thinking about this for a long time and goes into detail:
Bobby and the Casangrandes are really happy and excited to hear this, and the Casagrandes even offer to let Maria and her kids move in with them, claiming they have plenty of room (and at least that, Maria and the kids don't have to buy a new house). Maria and Bobby don't mind the idea of moving in with their extended family, but Ronnie Anne's clearly distraught by what has just happened.
Ronnie Anne breaks the news to Lincoln, who in turn, is shocked. Lincoln points out that Ronnie Anne could just tell her family how she really feels about the decision, but Ronnie Anne rebuffs that no one else will listen to her, as she's the only one who disagrees with it. Ronnie Anne requests to see Lori, who then tells her the announcement. Lori, furious at this revelation, quickly drives off to the apartment with Lincoln in tow.
Arriving at the apartment, Ronnie Anne notices them, and lets them in, albeit in scratches due to the homeless cats attacking them. Upon seeing Lori, Carl suddenly starts acting cool. Ronnie Anne introduces the family and Loud's to each other, with Frida thinking that Lincoln is her boyfriend, which they both deny nervously. While Lincoln gets accommodated with the Casagrandes, Ronnie Anne takes Lori over to the bodega, where Bobby's excited to see her, and leaves Lori alone with her brother. Lori lividly questions her boyfriend's decision to move in with the Casagrandes since they would be far apart, but Bobby tells her that he has thought of something and shows her around the bodega, leaving her unable to convince him not to move. So, she and Ronnie Anne try some different tactics to get him to understand:
Lori gives up, and decides she and Lincoln should leave since she couldn't get Bobby away from the bodega. Lincoln, not wanting to see all the emotional drama, goes back inside. However, Bobby finally comes and he and Lori talk things over. Ronnie Anne notices them hugging and Lori smiling, thinking that she finally convinced him and thanks Lori for doing that, thinking they can go back to Royal Woods now. But Lori reveals what really happened: after finally talking it over, and ultimately just wanting her boyfriend to be happy, Lori's willing to let Bobby stay with the Casagrandes and keep up a long-distance relationship with him--they can reunite after they get done with high school by enrolling at the college that Bobby and Ronnie Anne's uncle teaches at. Ronnie Anne is displeased that while the older siblings have it figured out, she still can't tell anyone how she feels and tries getting Lincoln to back her up. But Lincoln, who's more accustomed to living with a large family and who also had a lot of fun with the Casagrandes, ends up siding with them, Lori and Bobby.
That night, Ronnie Anne is sitting on the front steps, upset with how things are going to change. Maria comes out to see what's wrong with her daughter, who confesses that she doesn't want to move. Although Ronnie Anne loves the Casagrandes, she doesn't like the idea of living with so many people under one roof and that she really misses her old life back in Royal Woods. Not wanting to force her daughter into something that she doesn't feel comfortable with, Maria tells her they can go home tomorrow. Ronnie Anne's happy that her mother understands her plight and they hug it out. However, when they go back into the building, they forget to close the door, leaving an opportunity for the cats.
Just as Ronnie Anne's getting ready to pack her things, she finds that the closet isn't cluttered anymore and is now converted into her own personal bedroom, much like Lincoln's room back in Royal Woods. Realizing that Ronnie Anne's not used to living with so many people and that she likes to be by herself at times, the Casagrandes decided that she should have her own room and designed it the way that she would like, such as:
Ronnie Anne is touched with what they did for her and changes her mind about moving before Maria tells them that they wouldn't be moving in after all. Her mom's surprised by this and questions her about it. Ronnie Anne acknowledges that her mom was right in that it will be a big change, but they'll at least be surrounded by a family that loves them. But the moment is cut short when they realize that they forgot to close the door outside and the cats barge into the apartment and start attacking everyone. They knock over the cake Rosa had made for the party and Ronnie Anne catches it, but the cats pass by her, making her drop it on herself. When the cats leave, everyone laughs it off.
The next day, the Louds and Santiagos are saying their goodbyes with Lori and Bobby eagerly awaiting the day they'll see each other again, and Carl will be waiting for Lori as well, saying that he'll be there for her should Bobby break her heart and revealing a tattoo of her on his stomach (that he made out of Carlota's eyeliner, which she finds out angrily). Lincoln and Ronnie Anne are about to bid farewell, and Ronnie Anne hugs him instead of playfully punching him, something she's not too keen on. Before he leaves, Lincoln gives Ronnie Anne a little tip on how to deal with the new arrangements in her life.
That night, Ronnie Anne is in her room enjoying an ice pop and starts to talk to the viewers, which is the tip Lincoln gave her, about how she'll have to get used to living with the Casagrandes. She sees that breaking the fourth wall does help after all. Sergio flies in and tells her "Dream Boat", making her think the show is on and she rides off on Lalo to join the others. But Sergio, still under the potion's power, was referring to a picture of Bobby that he snatches with. The episode ends with Rosa looking at her special candle, claiming it never fails, and was the main reason why the Santiagos moved in with them, as she blows out the candle.
