Once he miniaturizes the Doctor, Drax turns the dimensional stabilizer weapon on himself and shrinks down to the same size. The Doctor runs over to the wall and ducks into a crevasse, avoiding the mute, and explains to the confused Drax that he wanted the technician to shrink the mute. The TARDIS door is open and there’s no way to get to it, and they can’t enlarge themselves inside of the crevasse. ..Read the full recap
The Shadow: When the Key is mine, I shall dispel the light. And darkness and blight shall reign!
Drax: Me and the Marshal’s going fifty-fifty.
Romana: You and the Marshal?!?
Drax: Well, he’s out of a job now, isn’t he? I mean, no war, no job. So I took him on.
The Doctor: When did you arrange this?
Drax: In about a half an hour’s time I should think.
The Doctor: Fifty-fifty?
Drax: Well, sixty-forty, know what I mean?
The Doctor: We have the power to do anything we like. Absolute power over every particle in the Universe. Everything that has ever existed or ever will exist. As from this moment. Are you listening to me, Romana?
Romana: Yes, of course I'm listening.
The Doctor: Because if you're not listening, I can make you listen. Because I can do anything. As from this moment there's no such thing as free will in the entire Universe. There's only my will because I possess the Key to Time!
The Doctor: Key to Time, I command that you stay exactly where you are!
The Guardian: Doctor, you have fully activated all the TARDIS defences.
The Doctor: We can't be to careful, can we? It would be a terrible tragedy for the Universe if it suddenly turned out that I was colour-blind.
The Guardian: Doctor, release the Key to me immediately!
The Doctor: Unable to distinguish between the White Guardian and the Black Guardian.
The Black Guardian: Doctor, you shall die for this!
The Doctor: I think not. Remember, the Key to Time is still mine, rage all you like.
The Black Guardian: I shall destroy you for this. I will disperse every particle of your being to the farthest reaches of eternity!
The Doctor: Ah, well, I wish I could stay and watch you try. But you know how it is. Places to go. People to see. Things to do.
