If not Tyrion then who has Targaryen blood and can be the third head of the dragon?
I've heard it theorized lately that Jaimie will be the Prince that was Promised. He will kill Cersei as she is destroying Kings Landing before Danny can take it. Amidst all the destruction (salt and smoke) he kills her with Oathkeeper which was apparently lost by Brienne as she dies defeating the Mountain. It turns into Lightbringer as he kills the only person he loves in life, for him the ultimate sacrifice.
This fits a lot of the prophecy and fulfills Cersei's own as he is her younger sibling by seconds. It also sounds like something Martin would do, misdirection being one of his favorite things. The only problem is as I understand it, the Prince is supposed to be of Targaryen blood. Jaimie is not. That only leaves Danny, Jon and whoever the 3rd head is. Everything so far has really pointed to Danny. As Aemon saw it she has already fulfilled all of the prerequisites. But that would almost be too easy and obvious. A happy ending this show is not going to have. As Ramsey said, "If you think this has a happy ending, you haven't been paying attention."
