The Master in “Spyfall, Part 2”

If you're seeing this, you've been to Gallifrey. When I said "someone" did that, obviously I meant... I did. I had to make them pay for what I discovered. They lied to us. The founding fathers of Gallifrey... everything we were told was a lie. We're not who we think. You or I, the whole existence of our species, built on the lie of the Timeless Child.

Do you see it? It's buried deep in all our memories, in our identity. [sighs] I'd tell you more, but... [bitterly] But why would I make it easy for you? It wasn't for me.
