New Doctor Who Companion

So they announced the new Doctor Who companion as well as released a scene from an upcoming episode. Her name is Pearl Mackie and her character's name is Bill. I don't know the actress and I don't know if she's known in the UK. From what I can see she's going to be a interesting companion, but it really is hard to judge from a two minute clip. I was hoping we'd get a male companion but I guess that's to much to ask for. Peter Capaldi's Doctor is growing on me. He's still far from my favorite but I'm excited to see the Christmas special and then the new season in 2017. Check out the two minute clip below.
