Arya exacts her revenge on house Frey
This was a surprisingly brief part of the episode, but we see Walder Frey brought a meat pie meal by a house wench. The wench removes her face to reveal that it’s truly Arya, and the pie that she has served him is made up of his chopped-up sons. Arya then slices his throat, and creepily smiles before cutting away. What’s most disturbing here is the ease with which we now see Arya conducting these killings, and how surprisingly sadistic she can be.
What does this mean for season 7?
Arya is officially back in Westeros, and it seems like she’s on a spree. If the threat of Dany and her armies and dragons won’t be enough, it looks like Cersei will also have to worry about Arya, as she is one of the last living souls on her list. Other than that, it’s hard to predict what else she’ll be after, but we can most likely expect a proper Stark family reunion down the line.
