I think Aria/CeCe or CeCe twin is A. I have an odd feeling about Wren too. But hey, the writers know how to throw shade at every character. I think there were way too many hints that Aria was A to believe she's the actual A. It's too obvious. But I would love her to be though. I heard theories that Bethany could be alive and be A. That's AWESOME. But if we get another "she's not dead or buried alive" most people are gonna get pissed. So I'm leaning toward cece/cece twin is A theory. I want to be surprised though :)
