Spn: Sam's Kid

Story: A few days ago, Sam, Dean, Cass, Rowena, and Jack found out something interesting. While doing a spell to ward the boys, Rowena used some of Sam's hair - DNA - to ward him. When she tried to perform the spell, the magic was attracted to both Sam, but some of it tried to go somewhere else; to another person. The magic didn't try to go to Dean. There was only one possible answer; Sam had a kid somewhere. So, the group, minus Rowena, went on a road trip to find Sam's child using a tracking spell. YOU: You are Sam's kid. Choose your name, age, gender, appearance, etc. (Ignore the voice. Good luck, friends)
