- Brigadier: Oh dear. Women, not really my field.
- The Doctor: Don't worry, Brigadier, people will be shooting at you soon.
- [the Brigadier comes across the Doctor saving him from the defence system]
- Brigadier: I just can't let you out of my sight, can I, Doctor?
- The Doctor: Brigadier Alistair Gordon Lethbridge-Stewart. So you recognise me, then?
- Brigadier: Yes. Who else would it be?
- The Doctor: [the Doctor stops the duel between Mordred and Ancelyn] STOP! I COMMAND IT! THERE - WILL - BE - NO - BATTLE HERE!
- Brigadier Lethbridge-Stewart: [showing the Doctor their ammunition] Armor-piercing, solid core with a teflon coating. Go through a Dalek.
- The Doctor: A nasty bullet.
- Brigadier Lethbridge-Stewart: UNIT's been very busy, Doctor. We've also got high explosive rounds for yetis and very efficient armor-piercing rounds for robots. And we've even got gold-tipped bullets for you-know-what.
- The Doctor: No silver?
- Brigadier Lethbridge-Stewart: Silver bullets?
- The Doctor: Well, you never know.
- Brigadier Lethbridge-Stewart: Quartermaster Sergeant! Silver bullets! Have we any?
