re: Crackpot ASOIAF Theories SPOILERS

Personally I think Howland Reed will seek out Jon very close to the start of the next novel. Once he heard he was Lord Commander of the Night's Watch, I imagine he personally has personally been marching toward Jon, but has had problems navigating around Moat Cailin. He will present two scrolls, both of which prove he is the rightful king. The first will be from Robb and his bannermen. The second will be from Rhaegar, Lyanna, the 3 Kingsguard, Ned Stark, and Howland Reed. He'll open up Robb's first and refuse it, but the second scroll will leave him for a shock and he won't know what to do.
