The Zygon Inversion (TV story)

 was the eighth episode of the ninth series of Doctor Who produced by BBC Wales.

This episode would show the Twelfth Doctor at his most emotional, having to describe the intense pain of fighting in the Time War, and how it's revealed that not only were there two Osgood Box's but that they were both made after the Moment, symbolizing how the Doctor had nearly destroyed his entire race with a box, just as Kate and Bonnie were about to do with the Osgood Boxes.

The Doctor

 * The Doctor nicknames Bonnie "Zygella."
 * The Doctor jokes that as he is over 2000 years old, he is old enough to be a Messiah.
 * The Doctor calls London a "dump". When Osgood says he goes there often, he says that doesn't mean he has to like it.

Clara

 * In the TARDIS Clara is seen fiddling with settings on the console. The Doctor does not appear to object, suggesting she knows what she's doing.
