(We are seeing a Gallifreyan soldier from someone else's viewpoint.)

SOLDIER: Don't try to speak. If you can hear me, nod. When the headcam's attached for the first time, your speech centres get a bit confused. You'll be fine in a bit. Do you want to try standing? Oh, that's it. It'll feel better any second. What I'm doing now is fusing the grid to your neural receptors. From now on, the headcam is downloading directly into your memory. A tiny part of your brain is now a hard drive. Takes up hardly any space. You won't feel a thing. Now, at the beginning, sometimes this has side-effects. (flash of a screaming soldier) I don't know what the guys have been telling you, but trust me, they're not premonitions, okay? Just side-effects, hallucinations. Okay, take a look in the mirror. I'm going to show you how the fittings work.

(Our soldier turns, sees himself and staggers back, falling over.)

SOLDIER: It's only an hallucination. It's okay, it's not real, it's not a premonition. Are you listening to me?

(A little later, the soldier puts on his helmet.)
