“Arya is in danger, she’s got an open wound in her stomach, and the one person who has protected her to this point unfortunately gets murdered. The fact that the Many-Faced God gets the people who have been promised to him really makes you think that there’s almost an inevitability about what happens to people who run afoul of the Faceless Men, as Arya has done.”
On the final part of the sequence:
“Arya’s telling Jaqen by putting the face on the wall that ‘this account is settled, and we’re good here, and now I’m going to walk away,’ and I think she knows what the answer’s going to be. The implication, obviously, is that Jaqen was, on some level, rooting for the outcome that he got. He may be “no one,” but there’s still enough of a person left in him to respect, and admire who this girl is and what she’s become. Arya finally tells us something that we’ve kind of known all along, that she’s not no one, she’s Arya Stark of Winterfell.”
