It seems like the cast and crew of the "Doctor Who" series are huge fans of the "Game of Thrones" series, and it's a fact that new cast member Maisie Williams likes to use to her advantage.

In "Game of Thrones," Williams plays the rebellious Arya Stark, who heartbreakingly loses majority of her family members at the hands of their foes the Lannisters, Freys, and Boltons. In season five, she even loses her half-brother Jon Snow, who was stabbed to death by his own brothers from the Night's Watch, and it looks like the remaining Stark family members who are still alive are her elder sister Sansa and younger brother Bran.

As for Arya, her eyesight was taken from her by the many faced god when she took a life that was not hers for the taking, so when season six starts, she will be dealing with her new predicament.

Fans of the "Game of Thrones" series are all dying to find out what happens next to the characters, and cannot wait until season six starts airing next year, so for them to hear spoilers before the season premiere would be a terrible thing indeed.

Williams knows this fact well, so when the cast and crew of "Doctor Who" would start teasing her, she knows which weapon to use against them - and it's not Needle.

"What would happen, like on the 'Doctor Who' set, was I would threaten people with giving them spoilers if anyone would wind me up. I would threaten to spoil the next episode. Or I'd go, 'I'll spoil the next season!' And everyone would be like, 'No! No! No! Don't! You can't give any spoilers!' So that was really, really good. It was a power I had over the whole cast and crew," she told Vulture.

Arya might have a lot of enemies in "Game of Thrones," but when the cameras stop rolling, Williams revealed that she actually gets along well with everybody, even the stars who play characters on the show who want nothing better than to get Arya killed.

"I know it's a common thing for people to do, to keep their relationships similar on set, but I've never been in anything where I needed a bad relationship like that," she shared. "I've been on sets with people who were playing my parents and with people who were antagonistic towards my character. In both cases I've gotten on really well with them, had lots of conversations."
