When Sam woke up he was tied to a chair over a Devil's Trap.

Fuck.

Dean was seated just outside the Devil's trap on a stool, holding a manilla envelope.

"What is this?" Sam asked.

Dean opened the manilla envelope and showed him the picture of a corpse. "Demon," he said. "Blood drained. Got anything you want to tell me?"

No. This couldn't be. He'd been off the blood for years. "Dean, it wasn't me. You have to believe me."

"You're a junkie Sam. Junkie's lie."

But it wasn't Sam. Which meant there someone else was out there draining demons.
