I know Misha is already confirmed for S13 but I found this theory:

I think, actually, the biggest clue pointing towards it having been AU!Cas is, in fact, AU!Bobby.

''Bobby, who lives in a world taken over by a war between Heaven and Hell. A Bobby who never learned to love a weird dorky angel due to his love of his adopted son(s). A Bobby who was downright giddy when talking about killing angels. But yet, didn’t kill Cas, because he was “different”. Bobby wasn’t our Bobby. He was different. And he somehow knew Castiel enough to not kill him, despite him being something he enjoyed killing.''

It was not our Cas that brought the boys into that portal.

There’s also the fact that we never saw Castiel come out of the portal the first time.

''One moment, he’s facing down the demon. Then mystery man shows up. And then he’s suddenly back at the house with Kelly, not understanding why she’s in pain.''

''He seemed to know quite a bit about the AU world for the seemingly short amount of time he spent there. And he was oddly calm about the rip in time and space.''

Honestly, I don’t think our Cas ever came out of that portal.

I watched the first 20 minutes of the episode and it totally makes sense.. to me at least. Thoughts?
