That raises the question: Where exactly has he gone? We know his car has also disappeared, but beyond that, there aren't a lot of clues about what he's up to. Read on for our top four theories about his disappearance — and then we want to know what you think!
He is trying to find out about Ali's body: Remember, Jason (Drew Van Acker) did end up writing a giant check to a mystery person, theoretically for info on the whereabout of Alison's (Sasha Pieterse) body. Maybe he's following up on that.
He is trying to find evidence against Garrett:Jason seems just as convinced of Garrett's guilt as the Liars, and, being part of the NAT club, he might actually know something about how and why Garrett might have been involved with Ali's disappearance and death. While drunk, he rambled about being in jail with Garrett and guilty people getting their dues. Maybe he has made it his mission to keep Garrett behind bars.
He's been kidnapped: Hey, it wouldn't be the first time someone has been forcibly dragged off in Rosewood. We just hope he's okay!
He really is just getting his car fixed: Maybe Toby (Keegan Allen) is right … But we kind of doubt it.
