My Season 12 Finale Theory
Ok so, this is just my theory, mixed in with some head canon but inspired by the 2 in 1 teaser reel. So... ya ready?
I think, for reasons unbeknownst to me (or you) yet, that Dean is being fed Mary’s memories via the electrodes on his head. The crib in the beginning of the teaser, is set in a 70s style living room. I believe this to be Dean’s crib. Sam’s crib had been in his room, and this is a completely different crib than Kelly has for Luci Jr. But why is it in a living room and not a nursery? If you remember in S5, The Song Remains the Same, Mary just finds out she’s pregnant and John loses his job, so maybe when Dean is born, they hadnt been able to afford their little home, but had to move in with John’s mom. Grandmom Winchester.
This would be cool since we have no idea what ever happened to her after Henry died. She may have remarried... In “In The Beginning” John and Dean are in a diner, and a man talks to John and says “Tell your old man I said hi” Implying his father is still alive, but we know he wasnt, so how about step father? Maybe John and Mary moved in there so they could save for a new place and among the memories Dean recieves from Mary, are that of their grandmother? Maybe they were even close to her until Azazel came and John left her behind to keep her safe. MAYBE Sam and Dean have some 80 yr old grandmom somewhere?
Dean is going to find out something, some secret Mary kept, maybe about the demon deal or anything that could have transpired before he came to claim Sam, maybe theres a curse or something on Dean too and this is why he’s crying?
In part 2, episode 23, maybe we all see the future, and the mysterious man emerging from the mist with guns, is future Dean? Old Dean, like maybe 60ish? And they have to do something in the future to save the world today... hey, why the hell not?
I dont have a theory for everything we see, but what about these? Thoughts?
