Jayden

Jayden is an unseen character in Grand Theft Auto V.

Description
Jayden is a doctor in Los Santos, and runs a charity helping sick kids. He eventually starts a relationship with Tanisha Jackson in 2013, after she broke up with street hustler Franklin Clinton. Tanisha moved from South Los Santos to Jayden's house a few months prior to the events of Grand Theft Auto V.

Events of Grand Theft Auto V
Jayden is first referenced by Lamar Davis in the mission Franklin and Lamar, where he brings up the fact that he's either a brain surgeon or a lawyer. According to Tanisha on her Lifeinvader profile, Jayden has been teaching her proper table manners and occasionally corrects her pronunciation in front of people. He also planned to take Tanisha to Paris in 2014.

During the start of GTA V, Franklin and Lamar are unsure what Jayden's profession is, claiming that he could be a brain surgeon, a CEO, a judge or a lawyer. As the story progresses, Tanisha makes clear that Jayden is indeed a doctor on her Lifeinvader profile. Eventually, Denise Clinton bumps into Tanisha and Jayden offscreen, and comments on Tanisha's Lifeinvader profile that she made the right move on leaving Franklin, and comments on Franklin's Lifeinvader profile that it's time for him to move on.

Eventually, in the mission Lamar Down, Tanisha finds out that Stretch has set Lamar up to be killed by the Ballas, and she goes to Franklin's new house in Vinewood Hills to inform him about it, and briefly informs him of her imminent marriage to the doctor.

At the end of the storyline, Tanisha calls Franklin one last time to inform him about her wedding the following day. Franklin accepts this and wishes Tanisha the best.

Events of Grand Theft Auto Online
Despite Tanisha bidding Franklin an amicable goodbye the day before her wedding to Jayden at the end of Grand Theft Auto V, at some point between 2013 and 2021, her relationship with Jayden ended and she would reunite with Franklin, who went on to become a multi-millionaire and legitimate businessman by the events of The Contract update in Grand Theft Auto Online, through investments and other plays after 2013's Union Depository heist with well over $10 million. By 2021, Tanisha is married to Franklin with children and living in Frankin Clinton's house in Vinewood Hills.

Jayden is never mentioned in Grand Theft Auto Online, and the reason why his relationship with Tanisha ended is still unknown.
