One of the main relationships that rises and falls multiple times throughout "Pretty Little Liars" is between Aria Montgomery (Lucy Hale) and Ezra Fitz (Ian Harding). The two meet and make out in a Rosewood bar, only to find out soon after that Ezra is Aria's high school English teacher. The pair embark on a forbidden romance spanning the show's entire run, "A" constantly lurking in the wings threatening to expose their secret.
"Original Sin" seemingly offers a more realistic (and decidedly creepier) take on Aria and Ezra's relationship in Tabby (Kinney) and Wes (Derek Klena). As Tabby's boss at the movie theater, when Wes isn't flexing his authority over Tabby, fawning over how "mature" her movie knowledge is, dangling his elusive NYU-film-professor connections over her head, or saying outright that he's interested in her, he's incessantly finding reasons to make her stay late at work and offer her rides home.
It has yet to be seen whether their relationship turns into anything romantic, but considering the original "PLL" was often criticized for the romanticization of a student-teacher relationship, it seems Tabby and Wes's relationship might be "Original Sin"'s attempt at a course correction.
