His sketchy behavior. Lucas has acted really sketchy throughout the end of Season 2 and all of Season 3. Here's a (non-exhaustive) list of his most noteworthy suspicious actions:
That whole incident with Hanna (Ashley Benson) at the lake in Season 2, when he acted totally creepy and then ran away for a while. He claimed he acted odd because he lost Caleb's (Tyler Blackburn) money gambling, but that story seems completely random (Lucas doesn't have a history with gambling, as far as we know), and we don't really buy it.
His attitude. Once upon a time Lucas was a nice guy, but these days he's jumpy, sullen, and downright mean. Even his friendship with Caleb seems to have been destroyed. Is the pressure of being on the "A" team getting to him, or is it just regular teenaged angst?
His anger issues. At a deeper level, we know Lucas has anger issues, as evidenced by the fact that even back when he was "nice" he destroyed Ali's grave and lashed out at Hanna while drunk.
Why he might not be the betrAyer. While all signs point to Lucas being up to something — most likely something "A"-related — we're not convinced he's the big betrAyer. Why? Because the betrAyal is supposed to be shocking, and the betrAyer is being billed as someone close to the girls. Lucas has only ever been close to Hanna, and at this point they aren't really friends anymore. And as for it being shocking … Well, just look at that list we put together. The only thing that would be surprising at this point is if Lucas isn't up to something bad.
