“The Zygon Inversion” is episode eight of season nine of the new Doctor Who.
At the end of the previous episode, “The Zygon Invasion”, the Zygons had taken control of a large part of London and had neutralised UNIT. The Doctor had called Clara, but the call was answered by Zygon Clara, who calls herself Bonnie. Bonnie told the Doctor that both Clara and Kate were dead, then fired a missile at the Doctor’s plane.
It seemed unlikely that Clara was dead, and debatable that Kate was. This episode opens with Clara apparently in her home with no exits. She isn’t, but she’s linked to Bonnie, and manages to make the latter miss the Doctor’s plane with the first missile. By the time the second missile was launched, the Doctor and Osgood had managed to jump out (although, if there was anyone piloting the plane, they presumably died. They apparently weren’t important enough to consider).
Bonnie and the rogue Zygons are looking for the Osgood box, but are having problems, because both Osgoods had set things up that way.
Quite a lot of talking in this episode by the Doctor, especially in the final confrontation and, like the previous episode, it’s aimed at current situations, so listening carefully can be interesting.
