Meera goes into Bran's chamber to say goodbye because she's going back home for when the White Walkers attack.
Bran is
and Meera gets annoyed.
Then Bran gives her an emotionless "thank you". Meera can't believe that's how he reacts after her brother and Hodor died for him and all she did to keep him safe.
Bran tells her he's not the same anymore. That he does remember all that happened to him as Bran but he has so many memories now.
Then Meera realizes Bran "died" at the cave and leaves.
Basically no one besides Bran acknowledges Meera (on screen) and she goes home without any sign we might see her - or her father - again
