I still think Howland Reed ends up at Winterfell. He would be the only person other than Bran that would know Jon's actual parents except maybe the nurse maids. Any chance the show held something back for GRRM to release in the books if they could get released before next April? They already unveiled the meaning of Hodor and the Tower of Joy but could they have purposefully left out something for GRRM to have a big moment in the books? I know GRRM has said that Hodor doesn't go down exactly the same but the meaning is the same, just unveiled differently. I imagine as a writer to have these things "spoiled" for you does suck. Even though the Tower of Joy was the worst secret ever, he did spend over a decade developing his books to get that reveal. I hope the Winds of Winter at least goes into more depth and maybe we get Lyanna's whole conversation.
