I still want to know how Chris Argent figured everything out. Why do all the hunters know more than Derek, actual mythical creature?

So, yeah, the Sheriff thought Stiles was making up the mythical creatures whatever, but why wasn't he curious at least about Cora? I mean, surely Stiles said she's a Hale, and wouldn't she be a missing minor case then?

wait but really what's wrong with Cora? I mean Peter was able to heal from being burned alive, what could be so wrong with her that she apparently needs the Darach to heal her or whatever?

guys Jennifer =/= Paige =/= Jennifer. Paige died in Derek's arms, remember? Not in the ER while birds crashed into windows/walls/whatever to sacrifice themselves

*whisks Derek away to a happy place where no one dies and no one is secretly evil and no one lights houses on fire or sacrifices people or gets bit by alphas* *hisses threateningly at Jeff Davis when he gets too close*

okay but seriously? does every love interest of Derek's have to end up evil or dead? pissing me off Jeff
