Fungous, I agree with many of your points. Ghost is more than a wolf I’m sure, how much more, not so sure. I am also pretty convinced that Jon is AA reborn, and probably TPTWP as well.
I don’t feel Jon can die at this point. Yes GRRM is capable of killing off anyone but too much would be lost if Jon where to die now, like that, for no gain.
So our options as I see them are:
1. Jon is not seriously hurt, much less dead.
I doubt this is the case, despite layers of clothing, his wounds are most likely serious if not fatal.
2. Jon will recover on his own, the old fashioned way.
Time becomes an issue here. The NW is falling apart, the Others are coming. If he is incapacitated for long, he is dead anyway.
3. Jon is brought back by Mel. He may flee into Ghost while his body is dying, then back once brought back.
This is certainly possible, yet there are problems with it. Mainly the North, especially the Wildlings will no longer accept him. He is one of the un-dead, brought back using the power of a God they hate and fear. They would never trust him again.
I don’t know if you have had the pleasure of reading this theory before, but here it is again. I still feel that it is fundamentally correct.
