TEXT: THE INVISIBLE ENEMY BY BOB BAKER AND DAVE MARTIN Part Three Running time: 23:28 [SCENE_BREAK] Inside, the clones struggle through the maelstrom. At least they hold on to each other. Shortly they find themselves in a surprisingly dry area. DOCTOR 2: Well, what do you think? LEELA 2: I don't know what to think. I've never been inside anybody's head before. DOCTOR 2: No. LEELA 2: It's very interesting. DOCTOR 2: Thank you. LEELA 2: Hey, why aren't we wet? DOCTOR 2: Because we're too small to break the surface tension. LEELA 2: What was that? DOCTOR 2: Oh, just a passing thought. Electrochemical reaction in the synapses. Leg wants to move. [SCENE_BREAK] Back in the lab, the Doctor's leg kicks wildly into the air, breaking the straps. Marius and the others hold him down. MARIUS: I don't think he can hold out much longer. The virus is strengthening its grip. LOWE (on screen): Marius! You have not replied to my ultimatum. I shall destroy this centre. MARIUS: No, wait! I agree to your terms. I have no further use for the Doctor. He's yours whenever you want him. LOWE (on screen): A wise decision. Tell me, Professor, is the woman Leela with you? MARIUS: No. As you can see, there's simply myself and my two assistants. She is somewhere in the Foundation, but I have no idea where. LOWE (on screen): No matter. She will be destroyed. Stay where you are. We are on our way. The screen goes blank. Marius goes over to the door and opens it. MARIUS: Leela! He gestures for her to come over. They're coming now. We must hold them up for ten minutes. Can you do that? LEELA: Can I borrow K9? MARIUS: Yes, certainly, certainly. K9, cooperate with Leela. K9: Master. LEEL
SUMMARY:
The medical center mounts a defense against alien forces trying to take the comatose Doctor while clones of Leela and the Doctor go microscopic so they can hunt down the intelligent infection that's in his head.
