The long-awaited reunion between Arya Stark and Nymeria took place in the second episode of "Game of Thrones" season 7. It was a moving scene and the fandom loved it, but the "That's not you" Arya line at the end of their encounter was pretty cryptic. That's why "Game of Thrones" showrunners Davide Benioff and D.B. Weiss decided to explain it.

What happened in the last episode of the show

In "Game of Thrones" Season 7, Episode 2, "Stormborn", Arya re-encounters an old friend of her: Hot Pie. The young but skilled baker informs her that "the Boltons are dead" and Jon Snow rules Winterfell as King of the North.

Arya, visibly excited, leaves the inn heading north.

Later, Arya is surrounded by wolves. But they are not common wolves. They are members of Nymeria's pack. Nymeria, who Arya sent away in Season 1 after the direwolf bit Prince Joffrey's arm, is now a huge, feral beast. Arya drops the sword and tells her: "I am finally going home. Come with me," but the huge direwolf and her pack turn away and leave. "That's not you," Arya says at the end of the scene.

The showrunners' explanation

As the showrunners explained in the "Inside the Episode," the "That's not you" line was a callback to "Game of Thrones" Season 1. At the beginning of the TV series, Eddard Stark describes to Arya a happy life for her in a great castle.

But Arya never liked the idea. "That's not me," Arya answers Ned in that "GOT" moment.

"Arya is not domesticated, and it makes total sense that her wolf would not be either," said Weiss. "Once the wolf walks away [...] she realizes the wolf is doing exactly what she would do if she were that wolf."

When her direwolf turns away, Arya realizes that Nymeria can't live in a castle.

By saying "That's not you" to her, she shows to have understood that she can't ask the fearless, wild animal Nymeria became to follow her like a common house dog. So, the line actually means that Arya still understands her direwolf.

Maisie Williams spoke about the reunion scene as well. "It’s even nicer that they don’t live happily ever after," the young star told to EW.

"Nymeria has created her own world and created her own pack and isn’t ready to be Arya’s pet."

Will we see Nymeria again?

We're pretty sure we're going to see Arya's direwolf again. An old statement by the "A Song of Ice and Fire" author apparently supports this idea. In a 2014 interview with Mashable, Martin said that he was going to use the giant wolf pack in the story. Since in the books Nymeria is reported to be leading hundreds of wolves, there is no doubt Martin was talking about Arya's direwolf back then.

If Nymeria does return, as it seems likely to happen, her next appearance will be epic.
