[Apologies in advance if this is bad. This is my first fanfic, so here goes! :P] Cas is your average 16 year old guy. Well, on the surface at least. His best friends, Sam and Dean Winchester, are hunters. They kill anything from Vampires and Werewolves to Shapeshifters and Demons. Cas doesn't have much experience with the supernatural, though he's very eager to learn and become a hunter. Dean is eager to teach him and Cas is ready to learn. But when Sam goes missing, Dean and Cas have to find him, and fast. Along the way, they discover a secret about Cas that he didn't even know himself. Can they save Sam before it's too late?
