Key Dialogue
"DOCTOR: These discs you wear round your neck. You press them to your forehead and you speak or hear through your mind, hmm?"
"SENSORITE 1: Ten years ago, five human beings landed on the Sense Sphere. Our planet welcomed them. Their minds were closed against us, although we sensed they thought our planet was a rich one. Then the five men quarrelled. Two of the humans took off in a ship. It exploded a mile in the atmosphere. We imagine they hid themselves aboard, then fought the other two for control. Anyway, all were killed."
"DOCTOR: Ah ha! I thought so. Yes, yes, yes, some kind of bargaining ahead of us."
"BARBARA: Look, I know how you feel, but your grandfather loves you. Be patient. We're all on your side really, you know."
"DOCTOR: Susan. We can't do without you. Can we?"
