New to the boards, this idea may have been previously brought up (if so, please point me in the right direction) but something along the lines of Theon's Redemption has been on my mind. Whether to bring Jon back to life, or for some other "noble" reason, I could see Theon (who is a fraction of himself now) sacrificing himself for the Starks to redeem some honor and prove his ultimate loyalty. In particular, he is technically a son of a king (as Balon declared as one of the Five) and king's blood can be used by Melisandre to resurrect....anything here? It's not well thought out or documented but thought I'd throw it out there to see if anyone liked that angle. Thanks
