I'm with ImperiexSeed, surely not all the alphas, maybe a few, I mean sure Dean and Crowley only think theirs one, but why would the alpha's make there presence clear to either hunters, or to a demon who had kidnapped and tortured hundereds of there kind?

There is bound to be atleast a few left, Personally I'm hoping for the alpha werewolf, I imagine him, or her, to look like an actual werewolf, like in the films, covered in fur, about seven foot tall, and can talk and is completely intelegent even in beast form, they can also change when they want, without the full moon.

So they can't have killed off all the alpha's it would destroy so many possible future episodes.

As for there reward, I think it was that his children would get there prey much more easily, but the levithans didn't tell him, that the food additive was toxic to all monsters but leviathans.
