- Peri Brown: Have you noticed the radiation level?
- The Doctor: What's a little radiation when we have a purpose, a mission in life?
- Peri Brown: Silly me. What's a little radiation sickness between friends?

- Peri Brown: Well, let's get outta here.

- The Doctor: Worse. Yes. Yes, well, p-perhaps you're right. The purpose of recommesance, after all, is to gether information, not to finish up face down in a pool of one's own blood - especially blood as noble as mine.
