Well, it certainly sounds like Michelle Gomez has made up her mind about this, but, dammit, it’ll be hard to see her version of Missy leave Doctor Who.
She debuted in the episode “Deep Breath,” and was slowly revealed to actually be the classic Doctor Who villain during the course of the season.
Her Missy was cunning, deceptive, sometimes wacky, mysterious, creepy and always a pure joy to watch.
Gomez has only played the character since 2014, when she took over as the regenerated Master from actor John Simm.
