"I’m the one who gripped you tight and raised you from perdition" -Castiel
I have thought about this scene SO many times! You see the hand print and you think "Wow, how did he do it?". And then Anna says that line "Dean Winchester is saved" and you imagine an army of angels laying siege to Hell and Castiel dodging demons and just grabbing Dean and lifting him up out of there... I don't know, I just always imagined it as this epic battle and I wish we'd been able to see it
This is basically just Cas hauling ass out of Hell trying not to drop Dean I guess lol!
