Martha: Don’t you want to know what I was really doing when I was walking the Earth?
The Master: [rolls his eyes] Go on then, tell me.
Martha: I told a story. That’s it. No guns, no bombs, just words. I told them about the Doctor. I told them my story, and I told them to pass it on, to tell everyone they could so that the whole world know.
The Master: [mockingly] So faith and hope…That’s your plan?
Martha: No. I gave them an instruction; I told them that if everyone thinks of one word at one specific time-
The Master: Nothing will happen! Prayer, is that your weapon?
Martha: -Right across the world! One word, just one thought, at one moment…But with fifteen satellites!
The Master: [freezes] What?
Jack: The Archangel Network.
Martha: A telepathic field, binding the whole human race together. All of them, every single person on Earth, thinking the same thing at the same time! And that word, is “Doctor”!
