Overhated AF

This episode was literally first mentioned in Series 11 episode 2, Ghost monument by a rag, then the destruction of Gallifrey shown in the episode was shown at the beginning of Series 12

This just shows Chibnall had a vision he followed through on.

The "Fam" escapes from the cybermen and destroyed Gallifrey. Thirteen isn't as lucky being arrested the second she re-enters her TARDIS
