Why haven’t we seen the white walkers? There’s only one reason why we haven’t seen the white walkers. Because Hodor’s been steadily doing his door-thing since episode 5 from last season.
I can’t wait for the scene of the Night King patiently speaking (muffled behind the door) “Now, Hodor, I think you’ve quite made your point old chap. We all have things to do, so you’ll just need to step away from that door.” (indistinct muffled chatter) “No, I bloody well don’t think he’s listening! (frustrated pounding) This is intolerable! Get me Martin on the phone… and another latte.”
