Professor Wagg
- Grace: Professor Wagg! This is Professor Bowman. He's from London. He was just going to share a secret with us.
- The Doctor: Erm, yes professor. Is there a chance of a closer look at the clock.
- Professor Wagg: No! No. I'm afraid I am the the only person allowed up there.
- The Doctor: Oh well, can't you bend the rules a little...
- Professor Wagg: No.
- The Doctor: Oh but you see...
- Grace: [Interrupting the Doctor] Grace says you have a big secret. What is it?
- The Doctor: [Taking Professor Wagg to one side] I'm half human.
- [pause as Professor Wagg gives the Doctor an odd look]
- The Doctor: On my mothers side.
