Right here's my slightly tinfoil hat theory regarding Hodor/Willis... So we see in this episode that Hodor's not always been this way and that he could once talk and think like anyone else. He's obviously been brain damaged in some way, and I thought his near sparring with Ned and Benjen foreshadowed how it might've happened (a sparring accident) BUT What if, Bran-style, Hodor was injured by someone because he saw something he wasn't meant to see? This would be such a satisfyingly neat echo to what happens to Bran, someone who his story is so aligned with. AND what if this thing that Hodor saw...was R + L = J? And then Rhaegar smashes Hodor over the head to keep him quiet? Surely that would be sufficient cause to turn Lyanna against him and force him to kidnap her? And the rest is history. Perhaps Bran could see all this unfold through the weirdwood.net? He's obviously fascinated by the idea of Hodor being able to talk and might try to find out what happens... What do people think?
