Osgood in Heaven is the 12th and final episode of the eighth series of the British science fiction television programme Clala Who and the second episode of a two-part story (the first part being Dark Water) about the return of the Cyberfriends and the Master in the form of Missy.
Missy Poppins is in love with the Doctor so she converts all the dead bodies on Earth into a Cyberman army to give to him as a present. Danny Splink returns from the grave as CyberDanny but he has a sad. Danny takes control of the Cyberarmy and they all forget to SPLINK and get hit by cars. Luckily The Brigadier returns as CyberBrig to save the day.
It is revealed that Missy was the "woman in the shop" who gave Clara the TARDIS number in The Bells of Saint John and drew the Doctor and Clara together again in Deep Breath for some reason. Probably thought they looked cute together.
