The "Pretty Little Liars" star recently told "Watch What Happens Live" host Andy Cohen that she thinks mysterious baddie "A" is “one of the four main girls" -- which doesn’t rule out her character, Aria. We've had our suspicions about Aria since season one, but is it possible one of the other Liars could be the enigmatic psycho-stalker? We weigh the possibilities, starting with the least likely Liar:
Hanna being "A" is highly unlikely. It's not that Hanna isn't smart enough to pull it off -- she is a secret genius, after all -- but Hanna seemed genuinely heartbroken over Mona's "A" reveal, and equally saddened by her death. Not to mention, "A" was the one responsible for sending her mom to jail.
And while Hanna more than anyone has a reason to hate Ali, if there's one thing we know about Hanna, it's that she's incredibly loyal to her friends. So we're putting Hanna at the bottom of our list.
Emily has always been the detective of the group, and her ace investigative skills could be a sign that she knows how to cover up her tracks. This is an important "A" trait. Em also has the strongest feelings toward Ali -- Ali was her first love -- so that would account for a motive. Plus, Emily was the first Liar to befriend Toby, who we know had connections to the "A" team. That being said, "A" also was responsible for driving a car into Emily's house, and we just don't think Em would put her mom through something like that, especially after she got her fired from the police station. Even though Emily has the motive, we don't think she has the heart to be "A." Now, Spencer on the other hand...
Spencer is the perfect "A" suspect: she's smart, conniving, and has a known ruthless streak. That, and she's Ali's biggest threat now that Mona's out of the picture. Spencer briefly joined the "A" Team in season three, but what if she never turned in her “A” Team badge? In the season four summer finale, Mrs. Grunwald implied that one of the Liars couldn’t be trusted. Could that Liar be Spencer? Sure, she seems to head up the “A” hunt, but what if that’s just a ploy? What if she’s the reason “A” is at least always one step ahead of them? Still, Spencer has an alibi to account for where she was at the time of Mona's murder. She had already been arrested for the murder of Bethany Young. So if Spencer didn't commit the murder, who did?
