The Zygon Inversion (TV story)

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

This episode saw the Twelfth Doctor describe the immense pain he felt while fighting in the Time War in an emotional and angry speech for the first time since his predecessor discovered that the War Doctor had not destroyed Gallifrey. It also revealed that there are two Osgood Boxes, and their design is based on that of the Moment; this symbolises how the Doctor nearly destroyed his entire race with a box, just as Kate and Bonnie were about to destroy theirs.

 * The newspaper in Clara's dream that she checks to ensure she's dreaming reads gibberish, indicating to her it holds no significance.
