George Martin pulls off a lot of surprises. I dont think Snow or Daeneris will rule at the end of the show
Another surprise might be Tyrion's disloyalty towards Daenerys when she starts fighting his brother Jaime. I speculate that Tyrion will be on the side of his brother in the end.
Agreed.
Anyways, Upon looking up at the odds they seem to be pretty bad, I don't know if they are going to be any better at the future, but all we can do is waiting to see.
Not placing a bet at the moment.
