I suspect, having read something the writers said, that they ARE messing with Aiden's character again and I'm not a fan of that. I could justify it in some way if it turns out to be the case though. Emily chose Daniel and her life of revenge over him...and then Daniel shot him. I doubt he'll be against her forever (if he is at all). I really hope not, anyway!
Aiden and Jack are Emily's two loves - the man who understands her and the man who understands her past. I personally hate her with Jack, who's just a drip and a bore. I mean seriously - he's so into Amanda Clarke that he'll fall for anyone claiming to be her?
I actually really enjoyed the first ep, but I also liked season 2 which many people hated. I just don't see how they can extend it out for more seasons...if the timeline is currently 2 months for Ems to get her revenge, get shot in a wedding dress and fall bleeding into the ocean... (Amanda all over again?!).
