I re-watched the episode and bawled again 
And it's just now that I realized Jon said to Edd something like: 
"Don't bring the wall down while I'm gone".
What is this s***? 

 I hate when they do this in tv shows. It's clearly foreshadowing.
I'd like to see what Bran does next,  how consume by guilt is he? or does he make another terrible decision or does he learn from this in some way. If the mark (of the Night King on his arm) broke the magic spell on the cave then the mark could break the magic on the wall if Bran passes south of the wall. The same sort of language has been used in the books to describe the magic of the wall, now if Bran goes back south of wall because it's safest place for him and Meera to go, to get to Jon, that could break the magic of the wall which could either let the White Walkers follow him or could even bring the wall down, I don't know. It's a huge guess. If Bran does THAT. Then I will start to give him a hard time. 
I don't think show watchers know that there's magic in the wall that keeps the White Walker's out and that's the main reason why they haven't marched south of the wall yet cause they literally can't get past the wall the same way that they couldn't get in the cave before. Maybe Benioff and Weiss let go of that idea and in the show it's just a big ass wall. No magic.

 In the books she's deep in the "no one" s**t to the point she forgot most of her childhood. In the show they're definitely going the other way, it doesn't feel like it but they're speeding things up just like Sansa. (who is still stuck in the Vale in the books)
I think they're skipping the "no one" phase of the book in the show, she directly doesn't buy any of it and doesn't want to be a Faceless Men. My guess is still that she will soon leave Essos and replace LSH.
