Supernatural ~ kid

Intro Sam, Dean, and Cass were on a normal case... until it wasn't. They were hunting down what seemed like a goul in some old, abandoned manour. Then, the leviathans spring their trap. The trio were cornered with no way out. With Castiel injured, he couldn't teleport then away. Just when things were most grim, a figure jumped into the fray; a kid. Using a strange ability, they were able to stun the laviathans, but they passed out just afterwards. Dean pucked up the kid, and the trio fled to a hotel You: You are the kid.
