Castiel nodded thoughtfully. "I'll do what I can."

He did't believe there were any children here, at least not by the generally-accepted definition. There were a lot of humans, though. There were people like Bruce who could be easily hurt. Castiel didn't want to see anyone hurt if he could help it, but his priority was to his friends. Dean always came first, of course, but Sam and his siblings and now Mina and Donna. He would defend them however he had to.
