Yesterday, the BBC announced that Michelle Gomez will be returning in Series 10 as Missy.
The female incarnation of the Master has appeared alongside Peter Capaldi’s Twelfth Doctor in both Series 8 and Series 9, so it seems fitting that she should join Twelve for his swansong series.
In true Missy form, the announcement came in the form of a video on social media of the actress painting what looks like a TARDIS.
