I'm going to try and post these every week day, which should put us ending it on or around December 21st for this shortened season. Sometimes there will be more than one cap for a beginning or ending of an episode. I'm also using my capper's discretion - meaning I'm choosing the most aesthetically pleasing image that we see first or last not always literally the first or last things we see. I'll explain this as we go along.

3.15 Beginning: The episode begins with this great tilted shot of a building (I think it was supposed to be a health club?) and 2 men walking out...one of which is about to be abducted and then shows up at a hospital with his liver removed. With a splash of holy water we see the brothers are interrogating a demon for information on who holds Dean's contract, but they don't get an answer.
3.15 Ending: Ah, Bela...if only she'd worked with the boys instead of against them they might have been able to save her from the hellhounds. However, she does share the info. that Lilith holds Dean's contract.
