Personally I didn’t mean for the Huntsman himself to come, just that whatever help he meant is going to. Whether it’s himself or his wolf or controlling another wolf or something else I don’t know. I think it’s would be one of the latter, simply because the actor for Graham isn't yet credited anywhere, but they might have done that on purpose. It would be cool, if it was the first option. 🙂 And if the whistle came up again, of course. xD
