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.

3.12 Beginning: Great first shot of the boys entering into Bella's motel room onto to find it empty and a trap has been set. Dean is armed and ready! Then we have Agt. Hendricksen entering the small police department where the boys will soon be put in a cell.
3.12 Ending: At the end we have dejected boys as they learn everyone at the police station was killed.
