He hadn't even thought about the friend endearment when it slipped out of his mouth. Even if the man was known as a trickster, he'd been nothing but decent to Wesley. It had been more decency than he had gotten in quite a while, so why couldn't they at least be light friends, if there was such a thing? This really wasn't the type of thing to think about right now. "See, now you've got me picturing foot high horns and I can't get it out of my head," he admitted with a laugh.

He'd been there enough in his life, thanks. He managed to shake the sense back into his head to see that Loki had pulled the creature off of him, and, grabbing his knife off the ground, slamming it into the demon's chest while taking care not to thrust it hard enough to possibly hit Loki as well. Right now he just wanted the thing to stop thrashing about and die.
