Yeah, that makes no sense. I think at this point, it has to come down to either Jon or Dany. On the one hand, I think those messages that Varys was sending could be significant in Jon's favor, but on the other hand, I read an article the other day where GRRM said that you don't always end up with the best ruler, which could be a hint that it will be Dany. A lot of fan theories have been blown to smithereens, including all of mine, so I really haven't got a clue.
