First Look at Tati Gabrielle In 'You' Season 3 & Premiere Date Revealed!

Tati Gabrielle is joining the cast of You for the show’s upcoming third season and the first look has been revealed!

The former Chilling Adventures of Sabrina actress takes on the role of Marienne, a smart, no-nonsense librarian who doesn’t let much get by her.

She is a keen observer of the neighborhood’s denizens, too savvy in the ways of the real world to be taken in by patrons’ privilege and oblivious entitlement. Beneath her practical, buttoned-up exterior, Marienne is hiding personal struggles that continue to set her back, hard as she tries to create a better life for herself and her young child.

Also featured in the new stills are Penn Badgley as Joe Gardner and Victoria Pedretti as Love Quinn, as well as new cast members Scott Speedman, Chris O’Shea, Shalita Grant and Shannan Chan-Kent.

In season three, Joe and Love, now married and raising their baby, have moved to the balmy Northern California enclave of Madre Linda, where they’re surrounded by privileged tech entrepreneurs, judgmental mommy bloggers and Insta-famous biohackers. Joe is committed to his new role as a husband and dad, but fears Love’s lethal impulsiveness. And then there’s his heart. Could the woman he’s been searching for all this time live right next door? Breaking out of a cage in a basement is one thing. But the prison of a picture-perfect marriage to a woman who’s wise to your tricks? Well, that’ll prove a much more complicated escape.

You season three premieres on Netflix on October 15th.
