WEISS: Right up until this point there was hope
that Arya could recapture at least some degree of who she was before.
She's not a little babe in the woods.
I mean, she understands that you have to be vicious in order to survive in this world.
But I think she still believes that you don't have to be a killer of innocence
to survive in this world.
After witnessing the Red Wedding from outside,
all hope for her is lost in that way.
She's certainly already had to grow up far too fast
and she's seen way too much bloodshed.
But there still remained a little bit of the core of that girl
and the hopefulness and the vitality
and I think it's extinguished forever in that moment.
It's over!
(GROANING)
(STARK SOLDIERS GROANING)
It's probably the worst thing that could ever possibly happen to her
and it's something that will forever change who she is.
Something snaps in Arya I think in that moment.
In some ways she probably...
Might spur her on to become a much greater force in the world
than she ever would have been if she hadn't witnessed these things.
But I think that the old Arya definitely dies with this scene.
It's too late.
(GROANS)
it goes back to what Melisandre said.
I see a darkness in you.
BENIOFF: That darkness is coming out fast now
and Arya is going to kill a lot of people before this is over.
