Her name is Pearl Mackie. I’m relieved that she’s not yet another white girl and I absolutely love that she has a big ol’ fro. The more natural hair we see on shows that appeal to an international audience, the better.
And I love that her character’s name is Bill. It’s so delightfully different.
At the end of the clip, The Doctor mentions going back to the future, and she’s dressed a bit late 80s/early 90s which is contributing to speculations that she might not be from the present day. That would be fun, I think :)
