Ahah! A bit of interesting new data, from the The Thirteenth Doctor #0 comic: the narration (from the Doctor herself) refers to the Master in a way that supports Game-Fanatic's suggestions. Missy is referred to as "when he was a woman" (emphasis mine). And this isn't a case of referring to an old incarnation of a Time Lord who has turned back into a man, since as we know, Missy is (until the next retcon) dead as a doorknob before she could regenerate.
