Spoiler alert! The following contains plot details from “Game of Thrones” Season 8 Episode 2, "A Knight of the Seven Kingdoms."

The White Walkers have nothing on Arya Stark when it comes to shocking an audience.

Sunday's episode of HBO's "Game of Thrones" was on the quieter side when it came to frozen zombie violence and death, but it still managed to stun viewers into silence (followed by Twitter jokes) with its most unexpected sex scene yet.

"Thrones" is known for its sex (for good and very bad reasons), so it didn't seem weird that, as the occupants of Winterfell braced themselves for an imminent battle, some would seek comfort in each other. But it did seem weird that one of those people would be Arya Stark (Maisie Wiliams).

Arya sought comfort in her longtime crush, former road companion Gendry (Joe Dempsie), telling him that she wanted to experience sex before she died. But she (and, of course, Williams) started out as a child on the show, and although both now are full-fledged adults, it was still hard to see her in such an intimate situation.

The partial nudity in the scene was also jarring, although Williams had the final say in that, she told Entertainment Weekly.

“(The creators) were like: ‘You can show as much or as little as you want,’” Williams, 22, told the magazine. “So I kept myself pretty private. I don’t think it’s important for Arya to flash. This beat isn’t really about that. And everybody else has already done it on the show, so …"

She also felt it was an important moment for the character. "It was really interesting because it’s a very human relationship for Arya,” Williams said. “This is something she’s stayed away from, an emotion we’ve never really seen her engage with. ... So it was that moment where she says, ‘We’re probably going to die tomorrow, I want to know what this feels like before that happens.’ It’s interesting to see Arya be a bit more human, speak more normally about things people are scared of."

It was a big moment for Arya, and fans were with her, or just plain bowled over by the situation.

Next Sunday, when the White Walkers attack Winterfell, there probably won't be much time for sex scenes. But you never know: This is "Thrones" after all.
