Update 3/19: The Pretty Little Liars Season 3 finale confirmed that Toby (Keegan Allen) is, indeed, alive. But that doesn't change the fact that on Episode 23, we learned that a body was found near where Spencer thought she saw Toby. Who's dead in his place? We're afraid it's Jason DiLaurentis (Drew Van Acker).
The body that was found was a male in his late teens or early twenties, but he couldn't be identified because of significant trauma to the face. In the episode tag, we saw that this body did have Toby's tattoo, so it's definitely who Spencer saw. But clearly the "A" team recreated Toby's tattoo on someone.
Why do we think it's Jason?
The main reasons are pretty obvious. The last time we saw Jason he was seriously injured, and now he's MIA, with only some texts "proving" he's okay. On top of that, there's a pattern of N.A.T. club members dying. If the "A" team is targeting the former club members, Jason would be next on their list. It's easy to see them deciding to use his death to their further advantage.
On top of it being general logical, there's also this: One eagle-eyed fan spotted what looks like it could be Jason's wound from the winter premiere on the dead body, and it looks like that wound might be there on the body in the morgue, too.
What do you think? Is Jason dead, or do you think he's okay?
