Pairing(s)/Character(s): Twelve/Missy, Twelve/Simm!Master. Twelfth Doctor, Missy, Simm!Master, Bill Pots.
Warnings: implied and forced mind control
Spoilers: it's set after The Pilot (s10e01) but it isn't compliant with how the series is going. Spoilers for a character who appears in the "coming soon" trailer but hasn't shown up yet in the series.
Summary: Something was out of time. Something was wrong, and the Doctor couldn’t pinpoint what it was. It made him feel nervous, wary, and protective of the human woman beside him. The Doctor is always clueless when he has to face who he knows best.
Disclaimer: Doctor Who and its characters aren't mine, I don't gain money or any kind of economic profit from this.
Author's note: Title taken from the song "Fury" by Muse, because its lyrics are kind of fitting for Twelve and the Master, in my opinion. Also, I'm new to this comm, hello!
