God also answered some questions about the absolute STATE of the multiverse:
-God doesn't know how many universes there are because "Heaven lost count. Most of them are boring"
-One has no yellow
-One is "just all squirrels"
-Alt Mike was lying his ass off about the book thing. According to Chuck, at least.
-This universes's S&D are the most interesting out of all the ones in all the multiverse. He watches them constantly, and they're "his favorite show"
...you know where this is going, don't you?
The resolution happens because the characters are possibly literally, in light of soon to be disclosed events
moving at the speed of plot. Jack has been wandering aimlessly as every single person he meets makes him feel terrible. Castiel finds him, and Jack feels terrible bceause he's a goddamn baby and just /wants/ to feel bad and his adoptive parents' approval which Cas wants to give. Somehow, this conversation takes /the exact amount of time/ it does for Dean to walk up with the balance gun. Jack doesn't fight back, he just kneels and says he's sorry for everything expecting death. Dean then hesitates EXACTLY LONG ENOUGH for Sam to drive there. And Chuck pops up outta nowhere.
Dean doesn't fire the gun.
Sam notices Chuck is smiling excitedly for some reason.
Dean doesn't lowers the gun because he suddenly decides Jack is NAKAMA on the spot.
Chuck panics and really, really wants Dean to fire the gun.
Chuck offers to rez Mary.
