He didn't care. Or that's what he told himself. He couldn't care. Because caring hurt. When those kids, stupid, useless kids got themselves killed, it broke him inside.
But that's alright. Because he didn't care about them. He was "the wine dude," who liked nothing except his pinochle games and his diet coke. He certainly couldn't be bothered to learn all of their names, and actually pay any attention to when they survived a quest, a big god like him.
Deep down, though, he loved them. But loving hurts. And when you've lived for eons, you get tired of pain.
