#but he does have his own new fave old musicians now - folks dean probably never listened to.

right on op

imagine cas annoys the empty so much again it spits him back out except...it spits him out into the wrong universe (and time) and that's how *our* cas ends up in the winchesters universe. and at first he doesn't realize it's not the right time or universe and he goes looking for dean and instead finds the Lebanon bunker closed off and eventually finds john + mary and he thinks it's his universe's past john and mary and he tells them he needs help to get back to his time (bc his grace is still too low). he tells them he's from the future and needs to get back to someone and he pulls out his wallet and shows them a picture of dean and they're like "whoa whoa we know that guy!!!!" and cas is like, "that's impossible. he hasn't been born yet." and they're like "no no he was here. he helped save our universe. he's from another universe and he came here from heaven because he's dead and there was this young guy with him, jack? and an older guy, robby or bobby or something...." and cas is just slowly losing his mind, all the color draining from his face because first of all what do you mean he's dead?!!! and then all the other universe stuff and then jack? and bobby??? and yea anyways they team up to help get cas to dean and along the way hmmm what if jack pops in again....only this time he's acting even weirder than before, because chuck / the god power are gaining more control / corrupting him more. and jack becomes the big bad, thwarting their attempts to get cas to dean, and wreaking havoc on their universe, so the winchesters squad help them save jack and then dean and cas can eventually get their proper reunion (which everyone in the winchesters squad is now nvested in, especially carlos, number one deangirl and destiel stan) oh and the whole time they also do not know dean is mary and john's AU kid because cas never gives a last name just keeps calling him dean. and so john also grows invested in seeing these two people get their happy ending and BOY would it be cathartic for dean to see a version of his father who is so happy to see dean happy with a man-shaped person<3
