I'm not agreeing with you on Bran being a villain. I do think that Jamie will one of the heroes because he will be the one that chokes cersi to death.

The more I read about the whole rhaegar/mance deal the more I think mance is actually Arthur dayne. Ned sent him to the wall after the battle of the TOJ was cut short due to the birth of Jon. Daynes life revolves around protecting the "king". Well once jon is born, Ned convinces dayne to take the black and he'll be able to protect him later down the road while Jon grows up in winterfell.

That also leads me to think that the faith will chose mance/dayne as they're champion against Robert strong. At the battle by combat mance/dayne will unveil DAWN and put a serious beat down on the mountain.

The emp is a targ, not the twins
