"The lift was downstairs, and quite possibly not empty."
                          
"Stand aside."
                          
"Do as she says."
                          
"Stand aside."
                          
"Do as she says. Is the future going to be all girl?" The Master asks.
                          
"We can only hope." The doctor and I say at the same time. Bill takes point, and we all point our sonic screwdrivers at the lift. The lift arrives, the doors open, and a Cybus-style Cyberman is revealed.
                          
"Fire!"
                          
"Kill it, kill it, kill it, kill it! Kill it, kill it. Kill it." We succeed in destroying it.
                          
"Missy, sonic the lift. Keep it here."
                          
"Why's it different? Why does it look like that?"
                          
"It evolved." The Master replies.
                          
"Exactly. Since we left, they've built a weapons-grade version to come after us. And we just gave our position away. Well done, the genius twins."
                          
"It doesn't matter. We can still get out of here. We go take the lift right to the top and escape in your Tardis. We could evacuate the Waltons back there, if you're feeling ridiculous."
                          
"We can't go back to the bridge. We can only go four or five floors up at the most. The further we move up the ship, the slower time moves for us and the faster it moves for the Cybermen. By the time we get to the bridge, they'll have had thousands of years to work out how to stop us. There is no safe way to get back to the Tardis. It's a mathematical impossibility." I say.

"Operation Exodus. Troops to attack phase."

An electronic siren sounds.
                          
"Nardole, what is that?"
The various modes of Cyberman are lifting off with rocket boots.
                          
"Tell me, what is it?" The Doctor and I run up.
                          
"Doctor? Seer?"
                          
"The Cybermen don't have fear, but they know how to use it. Operation Exodus. They're announcing their arrival. They're coming! The Cybermen are coming."
                          
"How long till they get here?" Bill asks.
                          
"Two hundred miles of time-dilated spaceship. According to my calculations, we need a plan, quick."
                          
"You realise this is hopeless, don't you?"
Nardole is using a laptop.
                          
"Oh, I was hoping someone would say that. For a moment there I was feeling a glimmer of purpose." Nardole says.

"But do we have long enough?"
                          
"They're Cybermen. There's no such thing as long enough." We open the trapdoor to the cellar.
                          
*Farm*
                          
The new design Cyberman has been brought here, and Nardole's laptop is connected to it.
                          
"But Nardole, look at it. They've got armour! We don't have guns that can shoot through armour."
                          
"Look. Give me one of them rifles."

The Master is practising applying eye liner.
                          
"Dearest, I've been thinking. We need your Tardis. We can't go up, but we can go down. Your Tardis is right at the bottom of the ship, isn't it?"
                          
"Well, I suppose." The Master replies.
                          
"Is it, or isn't it?"
