Solomon: What's the work?
Mr. Diagoras: A little trip down the sewers. Got a tunnel collapse, needs clearing and fixing. Any takers?
Solomon: A dollar a day. That's slave wage. Men don't always come back up, do they?
Mr. Diagoras: Accidents happen.
The Doctor: What do you mean, what sort of accidents?
Mr. Diagoras: You don't need the work, that's fine. Anybody else? (The Doctor raises his hand) Enough with the questions!
The Doctor: Oh no, no no no, I'm volunteering, I'll go.
Martha: I'll kill you for this (raises hand as well).
