The Liars may think "A" is gone, but we're sure the ultimate creepster is still around Rosewood somewhere, and every week we're on the lookout for new clues about who it could be. So, who's looking the most shady after Pretty Little Liars Season 5, Episode 3 (“Surfing the Aftershocks”)?

The episode didn't include any clear actions from "A", but here are three people we've got our eyes on.

Peter Hastings

Why He Might Be "A": Spencer's (Troian Bellisario) dad is sketchier than ever these days. He shuts Melissa (Torrey DeVitto) down every time it looks like she's going to reveal something important, and he's trying to downright intimidate Spencer into towing the family party line. He clearly has secrets, and even Jason (Drew Van Acker) thinks he can't be trusted. Plus, his run-in with Ali seemed like it was full of tense subtext.

Why He Might Not Be "A": Does Mr. D know more than he's let on? Unquestionably. Is he willing to push the bounds of decency to keep his secrets? Probably. Do we trust his motives? Not at all. That said, we're still not sure he quite fits the "A" profile. He's clearly a piece of the puzzle, but running around Rosewood in a hoodie doesn't really seem like his MO.
 

Ezra Fitz

Why he might be "A": Ezra (Ian Harding) is back in town even though he promised to stay away. He hinted to Alison (Sasha Pieterse) that he might know more than he's letting on, and yet he's not sharing that info with Aria (Lucy Hale) right now. Is he really just a repentant, love-sick writer, or is he actually pulling the ultimate long-con?

Why he might not be "A": OK, this one is a bit of a stretch, and would certainly require some major explanations about everything that went down in NYC with that whole gang of "A"s that chased the Liars around. Plus, we've already been down this road before; we're pretty sure the writers aren't going to go here again — but wouldn't it be a shocking surprise if they did?
 

Jason DiLaurentis

Why he might be "A": Jason seemed awfully intent on getting Spencer to stop digging into Mrs. D's death, and when that didn't work, he made a cryptic comment about their dad. Was he really being helpful, or was he trying to throw her off his trail? His whole "live and let live" philosophy, not to mention that he keeps conveniently disappearing for rehab, could be a clever cover.

Why he might not be "A": The finger has been pointed at Jason one too many times. Plus, we just really hope he isn't. We prefer him as Ali's conflicted, struggling, but ultimately loving older bro.
