1) Both Allison and Stiles are posessed - hence the "even if it is your own daughter" foreshadowing and why she hasn't been marked yet. Also, it would seem strange that she had so many hallucinations in the beginning and nothing came of it. Why would she be posessed and not Stiles? I know Claudia may have suffered from being posessed and passed it on to Stiles, but I think there must be something more to Allison and her "sacrifice" as well... They would very well be posessed by two different entities. Also Chrystal Reed hasn't been confirmed for season 4 yet - maybe she dies fighting this possession? Maybe Chris actuallly has to kill her?

2) Agent McCall is Derek's father. I know this is a bit far out, and I'm not sure the writers would actually do this, BUT they have put a lot of emphasis on family lineage and family names this season (Kira's father taking her mother's name, Scott asking Melissa why she kept the "McCall" name), and we know nothing about Derek's father, expect his "maiden name" can't be Hale, cause that's both Peter and Talia's name, AND Derek just saw Talia in that vision and she obviously told him something pretty important... And Agent McCall came back to BH to tell Scott something important, and Stiles and the Sheriff both know about it. Maybe they just know that Agent McCall had an affair with a woman, not knowing it was Talia and that she got pregnant?

I'm probably very very wrong about all this, but I like to consider every possibility :) 1) Has Allison shown any issues since More Bad Than Good? Nothing is standing out to me... But theres always a possibility.

2) It would make more sense for Melissa to have been the other woman in your theory. There would be no point in telling Scott that he had an affair with a woman who is dead, that as far as he knows, has no connection to Scott. Any children that he would've had dead in the fire. But if Melissa was the other woman, then he would've been with TLia longer, feasibly making Derek Scott's actual brother. Your theory has potential, if a few tweaks.
