I just honestly hope it’s not Aria!! and we know it’s not Mike because he’s leaving the show to be on Teen Wolf! Toby has been kinda freaking me out lately but I doubt it’s him! Marlene did say that A has been A since Mona went to Radley.
I doubt it’s Aria. I know there are a lot of theories regarding to her being A but I just can’t think of Aria as an “A” material. I hope, they don’t drag Toby’s A storyline again. Since A took the game from Mona, when she was in Radley, that’s why I think it’s Wren because he spent quite a lot of time with Mona. Also, Hanna visited Mona a lot. Mona hallucinated Alison’s presence there but what if it was Hanna since she’s also blonde and everyone gets her confused with Alison. However, I really hope it’s Wren because I wouldn’t like to see the girls falling apart.
