The tenth incarnation of the Doctor on Master (Doctor Who)

“Children of Gallifrey were taken from their families at the age of eight, to enter the Academy. Some say that's where it all began, when he was a child. That's when the Master saw eternity. As a novice, he was taken for initiation. He stood in front of the Untempered Schism. It's a gap in the fabric of reality through which could be seen the whole of the vortex. We stand there, eight years old, staring at the raw power of Time and Space, just a child. Some would be inspired. Some would run away. And some would go mad.”

“It can't end like this. You and me, all the things we've done. … Axons, remember the Axons? And the Daleks?… We're the only two left. I have no one else. REGENERATE!”
