He was the one who told the Winchesters that demons possess and I was still a girl in there. So I actually owe him in a way. If he hadn't taught them how to exorcise the demon, I could still be trapped like that. And I would love to learn some combat stuff, thank you. I can teach you some of the stuff I know in trade if you wanted?
He sounds like a really great kid. Maybe the Seal has a weird sense of sentiment (does the Seal even think?) wanting parents to be with their kids or something? And I don't think anyone fights harder than a parent protecting their child.
