(TIME) — Arya just changed #GameofThrones history. Here's how she did it.
Arya used the Valyrian steel dagger that was meant to take Bran's life in season 1 to save him and the living in the Battle of Winterfell.
After thousands fell during the fight in “The Long Night,” Arya managed to kill the Night King — and destroy every single White Walker and wight in the process. She saved Winterfell and all of humankind.
Arya realizes her fate in a conversation with Melisandre, who returned to Winterfell to help the living after being exiled from the North last season. (She tells Ser Davos that there’s no need to execute her as she’ll be “dead before the dawn.”) After escaping several wights in the castle with the Hound at her side, Arya speaks to Melisandre for the first time since the Red Priestess took Gendry away. Arya confirms that Melisandre does indeed see the future — she saw that she and Arya would meet again, and that Arya would kill a great many people. Melisandre tells Arya that the Stark girl has closed brown eyes, green eyes, and then pauses before saying, “blue eyes.” With that hint, Arya divines she is meant to kill the Night King and sprints away.
