Spoilers for "Game of Thrones'" Season 4 finale
Arya Stark might have ended Season 4 on a positive note as she sailed away to Braavos, but the season didn't end before she took a
very dark turn
. After the Hound spent more than a season caring for Arya in his own way, she left him to die without giving him the death he begged her for.
"That's her nod to the Hound saying, 'This is who I am now.' Episode 1 is the audience realizing, and then episode 10 is to the Hound: 'You thought you were brutal?'" Williams tells
. "All the lessons that he taught her, 'That's where the heart is,' and she's taking all of that in. ... [The Hound] is ready for her to kill him, and she just looks at him and walks away. And it's like, 'Yeah, you're right, I do know how to kill you. You taught me that. Thank you. But you're an a**hole, so thank you and goodbye.' It's sad."
When we spoke with Williams at the "Game of Thrones" Season 4 premiere, she expected audiences to be "a little bit angry" with Arya over the decision to leave the Hound. "They're starting to sympathize with the Hound, almost. They're starting to realize who he is," she says. "A lot of the cracks are coming away from the Hound in this new season. ... It starts to peel away, almost, this really rough exterior."
With the audience not seeing the Hound as the same villainous person he was in Season 1, Williams hopes viewers start questioning Arya's actions and motivations. "At that end episode, it's kind of like, was that necessary, Arya?" she says. "I hope the audience feel like, was that even necessary? That's what I wanted it to be like."
