Here's Another Doctor Who Season 9 Trailer (With More of Maisie Williams' Mystery Character!)

We’re in for a lot in this upcoming season of Doctor Who, not the least of which will be a character played by Game of Thrones‘ Maise Williams.

Her character pops up twice in this teaser, once in period garb with Clara, and again sporting a very different get-up in the company of a cat-person. This seems to imply that whoever she’s playing, she’ll be doing some time-hopping.

In addition to the Maise mystery, the Season 9 trailer also teases the return of Missy, Daleks, Zygons, and the introduction of a group of “deadly mercenaries called the Mire.”
