Wesen who freeze to death unless they kill humans, or hibernate. Alrighty, but kind of funny they're in Portland & this is the first time they've run into them. Seems pretty unlikely they hibernate there & then just go back to South Dakota or wherever they came from without killing anyone, but whatever.
So then - Nick & Co. start trying to dig through a big pile of them in the hibernaculum-thingy, to get the one guy out? If they'd have managed to successfully pull whats-his-face from the pile, were they going to arrest him & let him freeze to death in jail like his brother did? I also thought it was funny they took them all back to the basement because "they're innocent". Just how are these Wesen surviving without killing other humans? We're supposed to believe that none of them have been killing people to live, when that's what they DO?
