She's handy with a sword and can sneak up on you with someone else's face on, so blabber-mouthed Game of Thrones fans watch out: Maisie Williams is not happy with you.
The 19-year-old – who plays Arya Stark on the show – has told Radio Times that people leaking spoilers about the show's ploy 'really, really upsets me'.
"It hurts. It's just like, oh we wanted to tell this story, and yeah, lots of people don't want to read it, and don't want to look at it," she said.
"But then it's even more annoying when you know [the leaks] might be from someone on the inside, and it's just like… you're trying to make something really cool, that is really cool and people really like, and it's like "stop ruining it"."
She also labelled said leakers as 'sad' and said it's 'such a childish, annoying thing to do'.
The HBO show – rumoured to be making a return for season 6 on 25 June after a IMDb leak – only has two seasons left to run.
