Warning: This is not happy. I'm sure that's an understatement, and anyone who's seen part one of the S2 finale knows that. Spoils the end tremendously.

How It Ends
Sam stared down at Jake. It would have been easy to kill the guy, justifiable even, but he couldn't and wouldn't let himself be the damned demon's pawn. Wouldn't do what he knew was wrong on several levels. He took a shaky breath and wished with his whole heart and soul for Dean…and then actually heard Dean's voice and ohthankfuckdeanwasthereandalive. His whole body felt lighter just at the sound of Dean calling his name. He stumbled away from Jake's unconscious form, shoulder throbbing and jawbone aching intensely. Neither of those things mattered, because Andy's wireless communication had worked and Dean was there for him. He smiled when he saw both Dean and Bobby up the sodden road.

Hands on his neck now, his head wouldn't stay up and Dean was right in front of him but Sam could hardly see. He should be able to see. Tried. Taste of metal in his mouth. What? Eyes didn't work well, but enough. Dean's face was haunted, haunting. Forever.
