I'll try to post these every other week day (Mon-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.

6.12 Beginning: The episode begins with a fearful woman in a small plane in bad weather and she has reason to worry. Something is about to pull the pilot right out of the plane.
Our first view of the boys is of an unconscious Sam in the Panic Room where Cas is checking that Sam's soul has indeed been returned.
6.12 Ending: By episode's end, the boys save the girls and kill the most of the dragons, Sam knows what happened when he was soulless, and the Mother of All has been raised from Purgatory.
