"Belova," Winter says without hesitation. He hasn't asked her specifically, but he knows she'd do it. She could shoot him in the head if she needed to.

There's a pause, then, and he adds, "Though I do not intend to get like that. I don't have magic. And there is nothing I want except to keep people safe." So there's nothing the fear entities will be able to tempt him with, since he knows they won't want to keep anyone safe. Logic. He has it.
