Fandom: Supernatural, Supernatural RPF
Pairing: Sam Winchester/Jensen Ackles, past Sam Winchester/Dean Winchester
Characters: Sam Winchester, Jensen Ackles, Crowley, Demon!Dean Winchester
Summary: Two months after Dean died and disappeared, Sam is getting desperate, doing whatever he can to find his brother. He finds a locator spell that seems to work, bringing someone to the bunker who looks and sounds exactly like Dean, but isn't. Sam's missing his brother something awful, and having his doppelgänger around is pretty confusing.
Note: This is a little story that came to me after watching "Behind the Scenes: A Fan's Perspective," because I was worried about Sam being all alone after Dean left him at the end of Season 9.
