Jenna has had a dislike for Marisol ever since season 10 when Marisol began to flirt with K.C. The two were teammates on the Power Squad together, so Jenna was forced to put up with her. However, Jenna grew to hate Marisol when she discovered that Marisol and her then-boyfriend K.C. Guthrie had an affair. It was revealed that Jenna thought Marisol was a homewrecker.
In Dirt Off Your Shoulder (1), Marisol is at work with K.C. and listens to him talk about Jenna, saying she is upset that he's working too much. She suggests that she can help out by playing a game where they guess if the customer's relationships will work out. After work, Marisol suggests he stay after, but he's reluctant to do so because of Jenna. Marisol reveals that, every day after work, they have a "clean-up party." Then, he joins in, leaving Jenna at home.
In Lose Yourself (1), at school, Marisol comes over to K.C., who is holding Tyson. He tells her that Jenna is coming back to school, so they have to tone it down. Marisol tells him that they always have work and walks away when Jenna comes over to inform him that she's coming back to school.
In Lose Yourself (2), Jenna is seen at school. She asks Alli if she has seen K.C., but Alli hasn't. Dave walks up, telling Jenna that he and Alli are dating, and Jenna sees K.C. getting into a car with Marisol. She demands Dave tell her what's going on with Marisol and K.C., and Dave tells her. Later that day, Jenna confronts K.C. about Marisol, and they get into an argument.
In Don't Panic (1), Jenna is seen in the cafeteria where Katie, Marisol, and Mo are running for president. When Katie calls Marisol a "homewrecker" and that she stole "Jenna's baby daddy right from under her nose". Marisol denies this, but Jenna says it is true.
Into Smash Into You (2), Marisol makes a pitch at Model UN for a universal charity song, but Jenna responds that it is impractical as there would also be a problem with language barriers. Marisol rolls her eyes while Jenna is talking.
