(17 December 1966 - 7 January 1967)
[The Doctor is pretending to be a German doctor.]
You suffer from headaches?
[The Doctor bangs his head on the table.]
[The Doctor bangs his head on the table again.]
Oh, dear. You call me a liar?
I simply don't understand it.
Doctor, it wouldn't, I mean it couldn't possibly have anything to do with Lister, could it?
Well, I mean, you did say that you took your degree in Glasgow in 1888. It does seem an awful long time from now, 2070 or whatever it is.
Polly, are you suggesting that I'm not competent to carry out these tests?
Oh, no. No, no, no, no. I was just wondering if there was anything that Joseph Lister didn't know in 1888 that might possibly help you now.
Shh! Somebody's coming. It's Mister Hobson, out for blood. Ours. Look busy. Quick!
HHobson
Well Doctor, as I was saying, you've had your chance and you've come up with absolutely nothing. Now, I-
[The technician cries in pain and drops to the floor]
Now don't touch him! Let me look...
[The Doctor moves the technician and reveals his hand is covered in black lines]
HHobson
Charlie, and what's your name.. Ben, give us a hand to get him into the medical unit!
Try not to touch his skin.
[They both pick him up, and rush him to the medical unit. Hobson, Polly and The Doctor sit back down again. Then, The Doctor looks at the sugar container, with a look of realisation, then proceeds to knock the cup out of Hobson's hand just as he is about to drink the coffee.]
DON'T DRINK THAT! It's the sugar! Don't you see, that's why the disease doesn't affect everyone, it's the sugar! Not everyone takes it! Now don't touch it!...
[Polly and Hobson look at each other confused, as The Doctor picks up the sugar carefully with a piece of equipment and brings it to the lab.]
HHobson
What are you doing?
[The Doctor examines the sugar under a microscope, revealing the disease hidden inside]
Just as I thought. A large, neurotropic virus.
HHobson
Like the space plague?
No. A large, infective agent that only attacks the nerves. That's why the patients have these lines on their faces and their hands. It follows the course of the nerves under the skin.
HHobson
That's all very well, but how did it get in here?
Oh, it is the Cybermen. I believe they have deliberately infected the base.
HHobson
My men have searched every square inch of the base, there's no space to hide a cat, let alone a Cyberman! Anyhow, how did they get in?!
[Everything goes quiet for a second]
[The Doctor and co walk over to the medical room]
You say you searched all the base?
No chance of anyone hiding anywhere?
Did your men search in here?
[sighs]
HHobson
There are always people in here so they thought that...
[whispering urgently] Did they search in here?
But there's nowhere in here they could hide.
[the Doctor inspects all the beds in turn until he comes to one particular bed, where he sees the boots of a Cyberman sticking out]
There we are! In perfect flight!
Oh, and look what happened last time!
Oh, and all that a lot of fuss, it was just a bumpy landing, that's all, it won't happen again!
Let's have a look at the time scanner.
The time scanner! Instead of showing us a normal picture of where we are, it, gives us a glimpse of the future.
A second sight? Very dangerous...
Oh, nonsense! I, haven't used it much, it's, not very reliable as you can see..
[protesting against something] I... I will tell them. I will tell them. I... I'll do what you say. K-keep away. Don't touch me! I-I'll obey!
[a claw is seen on screen dragging the old man off]
What's that? What's happening!
Doctor, that was it? that thing in the picture! That was the claw! They're in control.
PPilot
Take them out of here. They are condemned to the pits!
The old shaft. Doctor, that's where Jamie is!
So they're going to pour this gas in the old shaft - gas they value above all else. What do you make of that, Polly?
For goodness sake, Doctor. What are you going on about?
Don't you see? Control are not pouring this poisonous gas into the old shaft to kill Jamie. They've quite another reason.
Doctor, you've got to do something to help him.
Before we act, we must think. Now, the Macra that have come to the surface of this planet have not found sufficient gas in the atmosphere, so they've had to get somebody to pump it up from down below.
But, if it's life and death to them, why do they waste it? Why divert it into the old shaft?
[thinking aloud] That's obvious, Polly, obvious. Because there's something trapped down there they wish to keep alive!
