Remember when this guy…
And got sucked back to Gallifrey during the time war?
Which considering it didn’t get destroyed now, means he could very easily come back?
“There was a goblin, or a trickster… or a warrior. A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos, and nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.”
When the doctor says things like these I like to remind myself he is actually a grandpa who has no idea what he’s saying.
