Not only were Game of Thrones and the Battle of Winterfell trending topics over the course of the day, but some Twitter users may have noticed the term "Mary Sue" grace their pages. Beloved GoT character Arya Stark–played by 22-year-old British actress Maisie Williams–didn't impress some fans after being the one to slay the Night King.

Williams spoke with Entertainment Weekly and said she was worried that fans would "hate" how the Battle of Winterfell was resolved and conclude that Arya "didn't deserve it."

"It was so unbelievably exciting," Williams said to Entertainment Weekly. "But I immediately thought that everybody would hate it; that Arya doesn't deserve it."

"The hardest thing is in any series is when you build up a villain that's so impossible to defeat and then you defeat them," she added. "It has to be intelligently done because otherwise, people are like, 'Well, [the villain] couldn't have been that bad when some 100-pound girl comes in and stabs him.' You gotta make it cool."

She concluded: "Then I told my boyfriend and he was like, 'Mmm, should be Jon though really, shouldn't it?'"

For reference, a Mary Sue is defined "as a type of female character who is depicted as unrealistically lacking in flaws or weaknesses," or simply, "a wish fulfillment." While some viewers complained Arya had little involvement in the show's White Walker storyline up to this point, others took to Twitter to point out that Arya had been preparing for this moment since the earliest days of the series.

Reminder that any time online fan dudes criticize a strong female character with terms like “mary sue” and “character development” and “storytelling” they are just mad that a woman got to be a hero and are using a facade of “valid intellectual critique” to mask their raw misogyny

This is really sad and so indicative of how we treat female characters/actresses. #GameofThrones

Fellow Game of Thrones star Sophie Turner–who plays Sansa Stark–voiced her support for Arya's triumph on social media after the episode aired.

Arya's role in "The Long Night" was one of the many female-forward moments for characters such as Sansa Stark, Cersei Lannister, Daenerys Targaryen, Lyanna Mormont, Margaery Tyrell and Melisandre.

Earlier in the final season, fans also applauded Arya's "sexual awakening" scene for putting female pleasure at the forefront. Throughout the Game of Thrones series, had often been used as a way to threaten and control women, but Arya's scene had a more positive, empowering tone.

Game of Thrones airs Sundays at 9 p.m. ET on HBO.
