Tommy: I've seen him. And he's like fire and ice and rage. He's like the night and the storm in the heart of the sun. He's ancient and forever. He burns at the center of time and he can see the turn of the universe. And he's wonderful.

Professor Yana opens his fob watch and comes to a realization:
"I AM the Master."
