It's a big night at the Loud House, because Pop-Pop has a new girlfriend, and he's about to introduce her to the family. Upon arriving, Pop-Pop introduces his new girlfriend as Myrtle, and she takes an instant liking to the family, especially the children and their individual personalities. When nighttime comes, Pop-Pop decides to call it a day, much to the dismay of Myrtle and the kids.
The next day, the siblings arrive home, and are surprised to see Myrtle at their house, doing some cleaning up. Eventually, Myrtle becomes a nuisance to the siblings, as she begins smothering them with her kind nature. After a whole day of Myrtle making their day a nightmare, the siblings realize that they need to get Pop-Pop to break up with her in order to get her to stop. Lincoln remembers that Seymour (the African-American elder from "The Old and the Restless") had an eye for Myrtle, which gives them an idea on what to do.
At the retirement home, Luan and Lori manage to get Seymour and Myrtle into getting into positions that make it look like they're about to kiss. After taking the photos, they're uploaded onto a computer, and put into a single image to give off the impression that they're kissing. Upon completing the photo, Lynn sneaks it into Pop-Pop's room. The siblings attempt to escape before they get caught, but Myrtle sees them, and reminds them it's her birthday today.
Inside, the siblings ask Myrtle why there aren't many guests. Myrtle reveals that she was a single child, and because of that, she doesn't have much of a family. She also reveals that the reason why she hooked up with Pop-Pop was because she knew that he had a large family, and thought it would help her get the family she has long wanted, which is why she was so smothering towards them. Realizing her pity, the siblings realize that Myrtle is not as bad as she is. Suddenly, they remember the photo they slipped under Pop-Pop's door, so Lynn and Lincoln attempt to retrieve it before Pop-Pop finds it. Unfortunately, it's too late, as Pop-Pop has found the photo, and is starting to chase Seymour around the pool. After a brief scuffle, the siblings reveal that the photo is fake, and tell Pop-Pop what happened prior. After explaining, Pop-Pop forgives his grandchildren, and proceed to the dining area.
In the dining area, as the siblings and elders celebrate, the siblings decide to head back home, and Myrtle promises to see them tomorrow. Luckily, Pop-Pop, noticing the worry in the siblings, tells Myrtle that they'll meet up with the kids on Sunday, giving the siblings some personal time.
Coincidentally, all 3 episodes have Darin McGowan as the storyboard artist.
It's also worth noting that Lincoln's section has more awards/trophies than before. If one looks closely, there's a book with the text "Wild Card Willy" on it, which is assumed to be the comic competition he won in "Pulp Friction".
Lucy's dislike of pink is shown in this episode when Myrtle decorated Lynn and Lucy's room pink, and Lucy hissed at it.
The title card music for "Patching Things Up" can be heard when the family was eating dinner at the beginning.
In one scene, Myrtle mentions that there were spiders living in Lucy's cobwebs. In reality, cobwebs are made from dust, and do not house spiders.
The music that plays when both Lincoln and Lynn were trying to retrieve the fake photo before Pop-Pop finds out about it, was used as the title card theme in "Cheater by the Dozen".
Sammie Crowley and Whitney Wetta have also written that episode as well.
This episode reveals that Luan cannot eat corn due to her wearing braces.
This is the second time the Loud kids were seen wearing matching sweaters, the first being "Picture Perfect".
At one point, Lynn wore her regular clothes in one shot, but then in another shot, her clothes were suddenly changed into her Ninja outfit. When Lincoln asked her how that happened, Lynn asked him how he changed his hairstyle back to normal. This is a gag on the cartoons error where a character's or object's appearance is changed from one shot to another without any explanation.
This is the fifth episode that had a title change during production.
If one were to notice, Luna had a somewhat irritated expression when she was wearing the sweater Myrtle made for her. According to Darin McGowan, the storyboard he made for that particular shot didn’t have Luna looking irritated, and claims that the way he drew her hairline may have been responsible for the animators thinking he wanted her to be irritated when wearing the sweater.
Innuendo: According to Myrtle, the reason why she deleted Lori and Leni's recordings of "Nail Polish Wars" was because of the foul language in it, which implies that Lori and Leni were watching a show that's out of their age range.
