Sarah: [the Doctor has ferreted out Sarah Jane's identity] Are you going to give me away, Doctor?
The Doctor: I don't think so.
Sarah: [suddenly cheering] Why not?
The Doctor: [leans back, tents his fingers] Well, you can make yourself useful. We need someone around here to make the coffee.
Sarah: [incensed] If you think I'm going to spend my time making cups of coffee for you...
[she halts as the Doctor leaps out of his chair. Reubish is scribbling something in chalk on the side of the TARDIS]
The Doctor: Professor! Would you kindly desist? This isn't a blackboard, you know!
[begins to unlock the TARDIS door]
Professor Rubeish: Oh, I do beg your pardon, Doctor. I was just trying to prove...
Sarah: What are you going to do in there?
The Doctor: [opens the TARDIS door] Make *myself* a cup of coffee. Good day to you.
The Doctor: Brigadier, a straight line may be the shortest distance between two points, but it is by no means the most interesting.
[Irongron and Bloodaxe approach a strange, spherical object, while the other men stay back with the horses]
Irongron: A star. A fallen star.
Bloodaxe: Careful, Captain, looks like the devil's work to me.
[a door swings open from the side of the sphere and a silver-suited and -helmeted figure steps out]
Irongron: A warrior? A warrior from the stars!
Irongron: [draws his sword] You've come to challenge me, sky warrior?
[the alien produces a probe-like device. Its tip glows and it emits a high-pitched whirring noise. Irongron's sword is knocked out of his hand in the blink of an eye]
Bloodaxe: Flee for your life, Captain!
Irongron: [steadies Bloodaxe] What creature is this?
Bloodaxe: 'Tis a devil from *Hell*!
[the alien holsters its weapon, then adjusts a device on his hip, making strange electronic noises. It appears to be a translating device as next-]
Linx: Peace. Fear not. I shall not harm you.
Irongron: It speaks. Who are you? Where do you come from?
Linx: I am a Sontaran officer. My name is Linx.
Bloodaxe: I say he's a Saracen. I have heard tales of his Eastern magic.
[Linx steps forward, plants a pole into the earth, and steps back. He salutes with his right arm at his chest and two pennants burst out from the pole in immediate response, white with a circled S in black on each]
Linx: [an eerie Sontaran anthem plays] By virtue of my authority as an officer of the Army Space Corps, I hereby claim this planet, its moons and satellites for the greater glory of the Sontaran Empire.
[Linx then adds his left arm to his chest-salute, completing the ritual annexing the Earth]
