Sure, we all knew that Michelle Gomez was returning as the Master in the next season of Doctor Who.

But now we know she’s being joined by one of her former selves: none other than John Simm himself.

I mean, sure, if the Doctor can bring along his past selves for adventures, why not his best friend/mortal nemesis?

That story, the final one of David Tennant’s tenure as the Doctor, saw Simm’s Master sacrifice himself to stop the Time Lords from wrenching their home world back into existence.

Even that was after he’d already “died” a first time in the climax of his debut in the show in season three.
