TEXT: THE ARMAGEDDON FACTOR BY: BOB BAKER AND DAVE MARTIN Part Five Running time:24:42 [SCENE_BREAK] SHADOW: And you shall be my eyes and ears. K9: Affirmative, master. SHADOW: Go now. [SCENE_BREAK] DOCTOR: Well, here we are. We've tracked him to his lair. ROMANA: Yes, we've got him exactly where he wants us. DOCTOR: All we have to do is find the sixth piece and stop the Shadow taking those other five. ROMANA: How can we get the sixth piece without using the tracer? Or had you forgotten the tracer's holding the Key together, and if we take the tracer out, we break the time loop, and without the time loop millions of people on Zeos and Atrios will die, to say nothing of ourselves. And the time loop's stretching already. It's up to six seconds now. That's four seconds left. And how long will that thing last? DOCTOR: Diagonal thinking, that's what's required, isn't it, Astra? ASTRA: What? I'm sorry, I was lost. DOCTOR: Astra, we need you to help us to find the Shadow. ASTRA: I shall stay here. DOCTOR: No, no, Astra, no. You're the only one who's ever been to the third planet before. Come on. ASTRA: I want to stay here. ROMANA: Astra, you said you wanted to come with us. Don't you want to save Atrios? ASTRA: My destiny no longer lies on Atrios. ROMANA: What do you mean? SHADOW (OOV.): (in Astra's head) Go with them. Bring me Romana. ASTRA: I understand. ROMANA: What did you say? Are you all right? DOCTOR: Yes, yes, everything's perfectly all right. Everything's wonderful, isn't it, Astra? ASTRA: What? Oh, I'm sorry. I was thinking about Merak. Yes, of course we must do everything
