I am confused about the place where Bran Stark and Jon Snow almost meet in this episode. Bran is in a tower with his allies whereas Jon Snow fights and kills some free people and leave Ygritte.
I don't understand if the action takes place to the south or the north of the Wall. I thought that Jon Snow was at the north side and was going south whereas Bran was at the south side and going north. If that's the case, how could they possibly meet?
Can anybody explain where these events took place?
