Seeing his sisters squabble with their roommates, Lincoln suggests a roommate shuffle, based on a compatibility test he and Clyde took.
Lincoln is in the living room, watching a baking show called Dessert Storm. However, before Lincoln can see which of the two contestants is the winner, Lola pauses the video, and begins complaining that Lana is ruining all of her dolls. Lincoln attempts to watch his show again, but this time, Lynn arrives, and complains that one of Lucy's bats bit her on the arm, and now has a taste for her blood. As Lynn runs away from the bat that bit her, Lincoln once again tries to see who the winner will be, but this time, Leni arrives, and complains how Lori's hair ruined one of her hairpins. Leni notices the show Lincoln is watching, and accidentally announces the winner, much to Lincoln's despair.
Lincoln enters his room, and gets a video call from Clyde on his laptop. As they begin talking, Clyde overhears a loud ruckus from Lincoln's side of the call, and Lincoln informs him that the roommates are squabbling with each other. As Clyde acknowledges the fact that he and Lincoln are great for each other due to getting the same score on a compatibility test, Lincoln realizes that if he makes his sisters take a compatibility test, he might be able to figure out which roommate is best suited for who. Lincoln proposes his idea to his sisters, and they immediately go along with it, not wanting to spend another moment with their old roommates. After one hour of taking the test, Lincoln has the results:
Lana with Lynn due to their rugged personalities.
Luna with Lisa due to their explosive personalities.
Lola with Lucy due to their flare for the dramatic.
Luan with Leni due to their shared love of laughter.
Lori with Lily because of their respective phones.
That night, Lincoln checks up on his sisters, and discovers that the sisters are getting along with their new roommates. However, just as Lincoln calls up Clyde to inform him that the compatibility test was a success, the roommates are already running into trouble. Lynn is complaining to Lana about her pet rattlesnake resting on her lucky jersey, Lola gave Lucy's bust of Edwin a makeover to bring him to the 21st century much to the latter's dissatisfaction since that is her least favorite century, Lori accidentally stepped on Lily's phone, prompting the latter to post embarrassing photos of her online, Luna's jams have gotten in the way of Lisa's experiments where the D6 note broke her beakers and her glasses, and Leni would annoy Luan by laughing at every little thing she would say, such as having to go to the bathroom. The sisters are quick to chastise Lincoln, since the compatibility test didn't work. Lisa looks over the compatibility test Lincoln gave them, and discovers that it came from one of Lincoln's Ace Savvy comics, meaning that the test only works on fans of Ace Savvy. Because of this, Lisa proposes on using an actual compatibility test.
Lisa unveils a machine that will calculate on which sister works best for the other by using collective data such as report cards, journals, medical records, and DNA samples. After scanning the information, Lisa is given a list on who goes with who: Lori with Lola because of their authoritarian nature, Leni with Lynn where they asked Lisa how they are compatible at the same time, Luna with Lana because of their garage-based hobbies and their respectful axes, Luan with Lucy due to their shared creativity and their way of befriending inanimate objects, and Lincoln with Lily, leaving Lisa all alone. Lincoln objects to this, saying that he and Lily have nothing in common, and Lisa wants a roommate but she seems to match with no one. This confuses her and as she scratches her head, her hair accidentally falls off, revealing her brain to be a pulsating green, much to the horror and disgust of her siblings.
That night, Lincoln is unable to sleep due to Lily babbling loudly in her sleep and the smell of her diapers contaminating the entire room. Lincoln barges into his room (which Lisa is staying in), and complains that her compatibility test must have some flaws as well. Lisa looks over the information, and discovers that the sisters who are paired have compatibility over 90%, while Lincoln's compatibility with Lily is only a measly 17%. Because of this, Lincoln threatens to make the sisters go back to their original rooms, but as he does so, he sees that the roommates are getting along really well. Luna and Lana get along by playing with both mud and drums, Lynn uses Leni as a weight, causing the latter to use that to decorate the ceiling, Luan and Lucy are getting along playing a friendly game of poker, and Lori and Lola get along bossing others around with their strict behavior. As Lincoln heads back into the room he's staying in, Clyde calls him, and he tells him that his sisters are happy with their new roommates, and because of this, he decides to take one for the team by letting them stay that way, and accept the fact that he has to stay with someone he doesn't have a lot of relatability to. Unbeknownst to him, the sisters overhear his conversation, and look at each other with concern.
The next day, Lincoln wakes up, and discovers that he's back in his original room. Just as Lincoln begins to question whether or not he's dreaming, the sisters enter, saying that they overheard his conversation with Clyde last night, and are grateful at the fact that he decided to take one for the team, so they decided to return the favor by going back to their original rooms with their original roommates, saying that they'll try their hardest to correct their behavior. As Lincoln appreciates his sisters for what they did, they all leave, except for Lisa, who informs him that some of her chemicals might still be in his room, and says that if he ever finds one of them, he should let her know. Suddenly, the second Lisa leaves, one of her chemicals blows up in Lincoln's room, covering the entire room in soot, and his hair to fall off, revealing that he now has a pulsating green brain just like Lisa does.
Bobby has no lines in this episode. Albert is mentioned in this episode.
The title card depicts a blueprint of the Loud House's second floor.
Lincoln appears on the title card as a little doodle of his head in Lisa and Lily's room.
This also makes the third episode where a doodle of Lincoln's head is used in the title card instead of his physical appearance. The first time was in "Save the Date", and the second was in "Making the Grade".
Lynn can lift Leni with ease, but needs Lana's help lifting Lincoln, meaning that Leni weighs less than Lincoln.
In "House Music", Leni can lift Lincoln with ease, so that means Leni is stronger than Lynn and Lana.
The arrows on the title card goes as follows:
Lincoln to Lisa's bed, and then back to his bed.
Lana to Luna/Luan's bed.
Luna/Luan (specifically Luan) to Lynn and Lucy's room.
Lori to Lana's bed.
Lynn to Leni's bed.
This foreshadowed the second room shuffle.
This is one of the few episodes where Lily says actual words.
This episode reveals that Leni thinks Luan's jokes are funny.
Aside from a few exterior shots, this episode takes place only within the Loud House.
This is the second time Lisa is seen bald, with the first being in "Potty Mouth".
In that episode, thanks to a nuclear experiment gone wrong, it was revealed that her hair is actually a wig.
Lana has a pet rattlesnake, despite the fact that rattlesnakes are venomous.
This is the first episode to feature Lily's phone.
This episode reveals that Lucy's least favorite century is the 21st century (in other words, the present).
Lana once tried to cut the hair off of one of Lola's dolls in "Along Came a Sister", but didn't get the chance. This time, she succeeded in doing so.
Roommate shuffles suggested by Lincoln and Lisa:
Lincoln - Ace Savvy comic book
Lincoln's room - Lincoln
Lori & Leni's room - Lori & Lily
Luna & Luan's room - Leni & Luan
Lynn & Lucy's room - Lynn & Lana
Lana & Lola's room - Lucy & Lola
Lisa & Lily's room - Luna & Lisa
Lisa - DNA Machine
Lincoln's room - Lisa
Lori & Leni's room - Leni & Lynn
Luna & Luan's room - Luna & Lana
Lynn & Lucy's room - Luan & Lucy
Lana & Lola's room - Lori & Lola
Lisa & Lily's room - Lincoln & Lily
Lola was the only sibling who didn't change rooms in either of the two shuffles, while Lana was the only one who didn't stay in her own room in either of the two.
Lucy and Lana were the only two siblings to switch rooms with each other in the first shuffle, while Lincoln and Lisa were the only two to switch with each other in the second shuffle.
This episode reveals that Lori has a double chin, when Lily takes photos of Lori and posts it on the internet.
Lori's "Bad Side", mentioned in "Save the Date", appears when Lily takes a picture of Lori at a certain angle.
Both this episode and its sister episode, "Out of the Picture", feature Lily taking a picture with a mobile device.
Though, in this episode, Lily uses a phone, and in "Out of the Picture", she uses a tablet.
Both Lincoln and Lisa were organizing the tests, and they both have a desire to be alone.
The sisters all changed back to their original roommates for Lincoln, but it was unnecessary for all of them to change back; the only one who actually needed to go back was Lisa, who was the only one without a roommate, and would've went back to living with Lily either way.
When Lori broke Lily's phone, she could've bought her another one instead of standing there, like she did in "Get the Message", where she broke Lincoln's VR glasses and bought him another one.
It could be possible she didn't do so since it was nighttime.
Room with a Feud - The title is a pun on the phrase, "room with a view".
Some of the sisters' squabbles don't make much sense, since they appear to be one-sided. One example of this is when Lynn said that one of Lucy's pet bats bit her on the arm. While this may be a problem for Lynn, it's not a problem for Lucy.
When Lincoln is trying to sleep, his eyes are bloodshot, but when he gets up to see Lisa they're gone.
Lynn and Lana are shown to be incompatible with each other, even though the two got along fine in "Linc or Swim" and "Suite and Sour", and also despite the fact they're close to each other due to their tomboyish natures.
In the Latin American dub, when Lisa presents Lori and Lola as compatible roommates, she says Lana's name instead of Lola's.
When Lola says that Lana and Lynn carried Lincoln while he sleeps, both seems exhausted, but in "Get the Message", Lucy holds him without any problem. Considering Lucy weaker than Lynn and a little stronger than Lana, they shouldn't have done any effort.
Also, Lynn carried Leni without effort when they shared the room.
The sisters pausing Lincoln's program to make him listen to them.
The sisters squabbling with their roommates.
Lincoln observing his sisters with their new roommates.
Clyde calling Lincoln on his laptop.
Lincoln and Lisa's hair falling off, revealing a radioactive green brain due to Lisa's chemicals.
