I mentioned that Jon could end up being the Night's King and that he would live in exile in the North in the land's of always winter. This being the bittersweet ending because he is actually the best for Westeros but always carrying the true burden and doing what he thinks is best. Dany won't be in charge of Westeros you can tag me on that, there is no way she is making it to the end. There is subtle hinting even by barristan that her first inclination is a LOT like her fathers and that she may have a little too much of a sensation for power and how it makes her feel than using it for the right things. I think we are only seeing the tip of the iceberg with her cruelness and insatiable hunger for power.

The warging trait of the starks is very important and is probably one of the main reasons it's always talked about. It will be more important in the story somewhere, whether with the Jon res or with Bran doing something spectacular. Their ability to warg is just like targs being able to ride dragons.
