TEXT: TERMINUS BY: STEPHEN GALLAGHER Part Four First Air Date: 23 February 1983 Running time: 24:49 [SCENE_BREAK] DOCTOR: We must stop the sequence. KARI: Do you know how? DOCTOR: Not yet. KARI: What, then? [SCENE_BREAK] VALGARD: Where are the others? OLVIR: What? VALGARD: Spies! OLVIR: Oh, no. Nyssa! [SCENE_BREAK] TEGAN: Are you all right? TURLOUGH: I think so. TEGAN: What happened? TURLOUGH: I don't know. TURLOUGH: Look! TEGAN: We must make it materialise fully. TURLOUGH: It won't move. TEGAN: Let me help. It's not going to defeat us now. [SCENE_BREAK] VALGARD: I wouldn't. The radiation'll kill you. Get much closer and you're dead, unless you can get to a decontamination unit. OLVIR: You're lying. VALGARD: Please yourself, then, but in my day we were better trained. OLVIR: What? VALGARD: You're not from the Company. You're combat trained. Colonel Pereira, was it? The one they call the Chief? OLVIR: How do you know? VALGARD: Recognise the moves. Taught the same ones to me. I was with him for five tours, till he turned me in for the reward. OLVIR: And how did you get here? VALGARD: Slave labour. That's how Terminus works. You couldn't pay anyone enough to work here. OLVIR: Where are the guards? VALGARD: Don't need them. If we don't work, we don't get the Hydromel we need to stay alive. Help me, please. Oh, come on. Look at me. I'm a danger to no one. I'm finished. I'm dying. OLVIR: Where did that thing take Nyssa? VALGARD: Nys
SUMMARY:
The Doctor discovers that the pilot had dumped the ships fuel billions of years ago and that the ship is going into another automatic fuel dump sequence because of the damaged engine. He determines that if the fuel gets dumped into space again, it will cause the destruction of the universe. Nyssa makes a decision that affects everyone.
