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.
Something or someone needs to reanimate Jon, certainly. Why not the children of the forest? Or Bloodraven? Or Bran, for that matter...
