re: Crackpot ASOIAF Theories SPOILERS

I think that in the Seige of Winterfell, Stannis and Ramsey are still at a stalemate somehow even after the Northern Conspiracy switches sides, and Howland Reed arrives with an army of Crannogmen to break the siege (possibly in the style of what Tywin Lannister did to the Mad King in King's Landing).

While there, Stannis receives a Raven from the Wall that Jon has been stabbed and won't live much longer. Howland makes haste to the wall to deliver the news to Jon, but he dies before Reed arrives. There, Melesindrie revives him and Howland delivers the truth, but to prove it, he must go to the crypts beneath Winterfel for some reason. There, Jon has a conversation with his "father" (Ned) somehow and receives the letter from the mailman right after the delorian disappears. It says that Doc is still alive, albeit in the Old West, but open the door, get on the floor, everybody walk the dinosaur.
