Wight Power

I think this points to Jon having to lie dead somewhere after the assassination. It suggests that he's turning into a wight, but a frozen inanimate corpse would do the same thing. He'll probably be dead dead for a while and then resurrected in some fashion. We also haven't confirmed how wights are created. There wasn't a conclusion for Jon's experiment with the corpses in the ice cells, personally I think an Other needs to do the deed.

I like the read of AA prophecy a lot, with the exception of smoke. I think fire still needs to be involved in some regard. For Quaithe's prophecy I guess the other names are associated in groups, but Tyrion didn't arrive with Connington. I think that leaves room for Aegon to be a fake or Varys' (the mummer) dragon.
