This is based off of one of my favourite editorials on my DeviantArt page.
This list will be about episodes where the Loud Sisters were nice to Lincoln or had them working together vs. the episodes where the Loud sisters were mean to Lincoln. First off, I'm going to mention the rules of my list:
1) An episode will be disqualified if Lincoln does something wrong and his punishment does not exceed the crime.
2) The Lincoln torture can't come from other characters (ie the Green House.)
3) I'm not including episodes where the fighting was every Loud for themselves (like the Sweet Spot.) It can only make the list if the sisters gain up on Lincoln.
4) An episodes placement on the list does not reflect my views on the actual episode.
5) And the most important rule: an episode will not be on the mean list if it ends with the Loud sisters doing something nice for Lincoln.
As an added note, I won't include No Such Luck because the actions of the family were out of fear rather than anger, plus Lincoln himself spread the rumor that he's bad luck.

And keep in mind that I only focused on episodes with all of the sisters, and my list does not include the one on one bonding episodes like For Bros about the Rock, Funny Business, and Frog Wild.)
Episodes where the sisters were mean to Lincoln -
Sound of Silence (Even if Lincoln was being rude, they do go overboard with their revenge.)
Sleuth or Consequences (They make fun of him for liking Ace Savvy.)
Lincoln Loud: Girl Guru (They laugh at him when he mentions his girl guru business.)
Brawl in the Family (The sister protocall.)
So even if you don't agree with my list, you can agree that the nicer moments greatly outnumber the meaner moments, even more so now that the second season has finished.
Also, I'm ok with you disagreeing about the list, but try to be civil in the comments section.
