Winter's gone.
When they walk out of the tunnel you see a shot with a little green sapling peeking out of the snow.
I doubt that Jon will be King beyond the wall - there is no more need for that role. But he certainly will hold a special position because he saved their lifes. While it looks like he's wearing the black, the way he looks back I also think that he will stay north and not join the ranks of the watch again. Maybe he can assume an ambassador role screwy
Sam is in an iffy position as well, still man of the watch, (unfinished grand-)maester, and what about his unborn child - shall it be b4stard-born? Anyway the question why he took part in the meeting of the lords - must have been already as grand-maester, as he is not allowed to hold lands and titles as man of the watch.
Will the Iron Islands be part of the North or the 6 kingdoms - in which case one would wonder to which kingdom they would belong - or it becomes 7 kingdoms again?!?!
