Game of Thrones actress Maisie Williams (Arya Stark) is guest starring on Doctor Who, and it won’t be pleasant for our favorite Time Lord. Lead writer and executive producer Stephen Moffat notes:
“We’re thrilled to have Maisie Williams joining us on Doctor Who. It’s not possible to say too much about who or what she’s playing, but she is going to challenge the Doctor in very unexpected ways. This time he might just be out of his depth, and we know Maisie is going to give him exactly the right sort of hell.”
We will have to use or imaginations for now since the show won’t return until this Fall.
