I'll try to post these every Wed & Fri, but I make no guarantees. 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.

7.17 Beginning: The episode begins with someone running along railroad tracks...
It's Sam. Poor, sick & hurting & hallucinating Sammy.
7.17 Ending: By episode's end, Castiel is back and transfers Sam's hallucinations over to himself. Now Cas is locked in the hospital instead of Sam, with new staff doctor Meg to watch over him.
