"Kids would do that?" Jack looks genuinely surprised. He's never been around kids. Most people he knows are adults. He was around teenagers once, they were supposed to be his friends, but it didn't work out. He doesn't know the type of mischief or boredom that would lead to bad behavior.

He looks curiously up and down. "Yes, it startled me too. I was hoping it was someone I knew. I don't know how they would find me, but I guess it wasn't a logical idea." Castiel would go looking for him, he knew that much. He would knock on doors. Jack has faith in his father. Maybe he should be doing that himself, but he's more shy than that. He doesn't want to cause problems. Or mischief, like children.

"I'm Jack. I don't know anyone."
