Maisie Williams a.k.a Arya Stark crashed into a fan's apartment to watch the worldwide premiere of the Game of Thrones season 6 on Sunday.

The 19-year-old gate crashed into a GOT 6 viewing party of some UCLA students and brought in snacks to dig in. She documented all the fun, and ultimate reactions of people on her Instagram.

The 12-part ' Surprise series', as we call it, started with a random tweet from William's official social media account where she urged fans to post pictures of their viewing parties.

"ANY @UCLA STUDENTS HAVING A VIEWING PARTY TONIGHT? TWEET A PICTURE OF YOUR PARTY USING #GAMEOFTHRONES FOR A SURPRISE," Williams wrote.

The actress then chose a lucky couple, who she named as Mark and Kate for the big surprise. William, as her Instagram says, went for a snacks shopping and amazed the couple and their friends with her appearance at their apartment an hour before the West Coast premiere.

"I found a couple, Mark and Kate, film students, who were throwing a party at their apartment, with a few friends. So at 8pm we left the hotel to go get snacks," Williams wrote in her second post.

And then it was some snacks shopping time...

 The time when you are all set for the surprise...

(5/12) We could hear the party inside so we had to be REALLY quiet!
