Game of Thrones Season 4 spoilers on Arya Stark's transformation

Arya Stark, played by Maisie Williams, has become a fan favorite character on the HBO smash hit Game of Thrones. Whether it's her ability to wield a sword or her "take no B.S." attitude, the young girl seems to resonate with fans. But according to Williams, those same fans might not be too fond of her by the end of the upcoming Season 4.

Williams spoke to the "Spoiler Chat" column at E! Online and previewed her character's arc for this season:

"Ugh, why isn't it March yet so I can watch Game of Thrones?! What can we expect?
Ch-ch-changes, which you might not like! 'Arya's really changing this year and I'm not sure people are going to like who she's becoming,' Maisie Williams previews of the fan favorite Stark. 'She's turning a lot darker and she's not quite as fun as she used to be...It's a different Arya than we've seen before.'"

Williams and the article do not elaborate on what these changes could be, but Game of Thrones by its very nature lends itself to misery for its characters, who could face death at any moment. Arya has spent her time out on the road for much of the series, particularly after the death of her father, Ned Stark, at the end of Season 1. It's possible that this situation has finally taken its toll on her, but we'll find out as Season 4 progresses.
