The Revere Hotel hosted a special screening of the premiere of the third season of “Game of Thrones” on Thursday night. The VIP guest for the event was teenage English actress Maisie Williams, who plays Arya, the youngest daughter in the House of Stark. (That makes sense if you’re a fan.) Williams told us, of her visit to Boston, “I haven’t been here before . . . but it’s lovely so far and I’ve been told to check out a couple cupcake shops.” As for season spoilers, she would only say that “this year, Arya’s growing up.” Williams told us she was happy with her tomboy character but admitted that “sometimes, it would be nice to wear a dress.” The rest of the world will get to see the season 3 premiere on Sunday.
