Game Of Thrones Season 6 Finale: A Dish Served Cold Video Released

WARNING! This article contains SPOILERS from the season finale!

The moment Walder Frey's ugly mug resurfaced in Season 6 of Game of Thrones, Stark supporters began foaming at the mouth wishing he'd get his comeuppance for The Red Wedding sooner than later, and in Sunday's season finale, "The Winds of Winter," they got their wish -- thanks to Arya Stark.

"As the seasons go on and on, it's still nice to be part of the show -- as not many characters make it," says Maisie Williams in the video above. "Upon reading my storyline this year, I was really excited. It's something we don't see, but when Arya arrives back in Westeros, she's out of touch with where people are. She's been out of touch for a really, really long time. But if there is one person on her list that she is 95% sure where they'll be, is Walder Frey.

Using the skills of disguise and deception that she acquired during her time spent at The House of Black and White, Arya is able to knock Walder off her kill-list. But before she reveals herself and kills Walder, Arya, who is disguised as a pretty servant girl, feeds him a pie made out of his sons. Noice!

"When Arya kills Walder Frey, she thinks it's very important for him to know exactly who she is," Williams explains. "It is the most unexpected family, in Walder Frey's eyes, that would come for him. He's done a lot wrong, but he's so confident that he's safe. And Walder Frey is such an evil, evil character. She doesn't need to explain why, he's fully aware of why she's doing it. Although Arya wouldn't know that her mother's throat was cut, she does the same deed. From a story point of view is very, very cool. One thing we can take away from this series, after watching Arya's storyline, is that she's definitely back."
