1. He nearly killed Thane, stole and injured kids, made war between 2 tribes and you think, he will be good boy after all?)
Or you didn't read the text after losing to him? How brutal he ends with you after sex...
2. Thane is still unconscious in the Tavern. Doppelganger took his form and backstabed Eywind (if u didn't pass skillcheck).
Don't worry, here are more chameleons (and I bet that Selye somehow involved to it). Thane said, he was attacked by several of 'em.
