Oh, this is so hard, um. It's a tie between
Sacrifice and
After School Special, I don't really know why. In Sacrifice I really connected with Crowley's character, I guess, seeing him so vulnerable like that. Possibly. And I can't explain why for After School Special. Maybe it was because we got to see what their lives were like as children, and Dean's protectiveness over Sam started really early. I honestly can't pick one, because so many scenes come to mind, but I don't remember the episode.
