"Manny: I'll be back before you know it.
Jay and Manny first started dating in We Got the Beat and broke up in Bust a Move (1) because Jay was too clingy. They got back together in Bust a Move (2) and broke up for the second time in Ladies Night after Jay stole Manny's engagement ring from a pawn shop. They started a third relationship in Degrassi Goes Hollywood and haven't broken up as of the series' end. Since both are off the show now, Janny is considered to be an "endgame" relationship.
In We Got the Beat, Manny is not looking forward to her Philippine Debut. In an effort to get her parents to cancel the event, she asks Jay to be her date, hoping that her parents will be put off by his "bad boy" nature and call the party off. Manny's plan backfires when she finds out that her parents sincerely like Jay. This made her want Jay to be even more repulsive. They both told Manny's parents that they aren't going to college, and Manny will work as a slave to Jay. Her parents see the problem with Jay, but before her dad could complain, she told him that she was just acting and presumably telling him that acting is going to be her profession.
In Owner of a Lonely Heart, Manny insists to Emma that there's nothing romantic between her and Jay. However, when a pretend date turns into an actual date and a pretend kiss turns into a real kiss, Manny and Jay are both pleasantly surprised. They pretend to get engaged to spite Manny's parents.In Bust a Move (1), Manny and Jay's faux-mance is working perfectly. However, when Jay gets too serious, Manny reminds him it's all fake. She's having fun, but the engagement thing is getting old - maybe they should 'break it off' after the road trip to Smithdale University, she thinks. When Manny, Jay, Ashley, Emma and Liberty are ready to go to Smithdale, Jay starts joking around about kids. Manny doesn't like it and kicks him off their journey. She remembers that she doesn't have her audition tape so she asks Jay for it. Jay, since he is mad, gives her a tape entitled "Manny xxx" and Manny doesn't see the title. As Jay walks away, the girls leave for Smithdale.
In Bust a Move (2), Manny discovers that her University demo reel is a sex tape that Jay made. By the time Jay catches up to her with the correct DVD, it's too late. Manny's already bombed her audition for Smithdale Drama School, so she throws their fake engagement ring on the floor and tells Jay to get out of her life for good. While everyone enjoys their road trip adventure, Jay hatches an awesome plan to get Manny into her program and to get back into her heart. In order to get Manny another audition, he pretends he is her agent and gives the judge a foot massage. After doing many other things, Jay finally gets another audition for Manny. Later, Manny aces the audition. At the Purple Dragon Concert, during the song My Window, Manny and Jay decide their engagement is real. They then kiss passionately.
In Sweet Child O' Mine, Manny and Jay are doing great together, until Manny wants to meet Jay's parents. Not wanting to tell her, Jay lies to her and says they live in Malta. At the Spirit Squad dance, Manny eagerly tells him that she bought tickets to Malta, so that she could meet his parents. Jay tells her the truth, that they don't really live in Malta, and Jay is angry, because Manny bought the tickets using the money from selling her engagement ring, which belonged to Jay's late mother. Though while walking down the street, they try to call and accidentally bump into each other. Jay says how sorry he is and tells her that he left his dad after he married his third wife and made a scene at the wedding, and never saw him again. Manny forgives him, and they leave together holding hands.
In Ladies' Night, Manny realizes that she has to get her pawned engagement ring back in order to stop Jay's pouting as it has real sentimental value to him. But she doesn't have any money, just two useless tickets to Malta. They go to an auction, but that didn't earn them enough money, only about $350. Jay goes back to his "old ways" and breaks into the store, stealing the engagement ring from the pawn shop. He gives the ring back to Manny who at first is thrilled. The she walks past the pawn shop and sees the broken window. She is upset and angry with Jay and breaks up with him once more.
