Ok, but imagine Chuck getting so sick of bringing Cas back that he upgrades him again. Only this time he dubs him a demi-god or an archangel of sorts that can create things from thin air like Gabriel.
But, instead of materializing junk food and women, Cas is always creating more and more creatures to fill the bunker with. Cats. Dogs. Guinea pigs. Panda bears. Dean isn’t sure what’s going on inside Cas’s room, but he’s pretty sure it’s something weird when he finally thinks he hears an elephant on the other side of the door.
