I'm looking for a gen coda to an ep - I don't remember what ep though XP I only remember that in the fic, Sam leads a hurt Dean to the Impala and leans him against the car and Dean basically passes out on him. I remember that in the ep, it didn't look like Dean was hurt much so it surprises Sam too. He is holding Dean and he has no idea how to open the car's door without dropping him.

Vague, I know. And it's driving me nutty!!!
