I was thinking that the reason for someone to remove Alison was to get the unborn baby from her? :shrug: I know it's gross but it could link the killer to her, maybe the killer didn't even know she was preg till after he murdered her.
And yea I kinda agree about Ezra (also I used to really like that name before this show, he's really turning me off of it) and this child of his, but if it breaks up him and Aria, I'm all for it :D last ep she nearly stole the show (although Meredith was the main star), and I put it down to her being Ezra-free.
I agree about Spence not telling them, she should have, especially sing A has put their lives in danger. But maybe she was just fed up with them too, like they weren't friends until Alison brought them together, and Spence was talking about forgetting about Alison and moving on, maybe dumping the other three as friends is part of her notion of moving on.
And I hope you're right about Paige.
Plus I guess after the drama of last ep, maybe they (the writers) wanted a quiet ep, so that could be another reason for Spence not telling the others about Toby.
And I haven't seen a trailer yet.
Also yea it could be that she has just picked Hanna first to target.
