- Kate Lethbridge-Stewart: My father, he'd tell me stories about you when I was a kid. He'd sit there in the firelight, telling tales of the Doctor, his eyes... shining. But he never, ever mentioned a granddaughter.
- The Doctor: I was a different Doctor back then, Kate. Great enigma. Still can't shake it off. I'm trying.
- Kate Lethbridge-Stewart: If you've got a granddaughter, that means you've got kids.
- The Doctor: Well, not quite. Not yet.
- Kate Lethbridge-Stewart: But, you mean... you can have a granddaughter before a daughter?
- The Doctor: Life of a Time Lord.
- Kate Lethbridge-Stewart: But... Ok, the grandchild exists and you've got the Tardis, but you've never gone back to see her. Why not?
- The Doctor: You've seen my life. I bring disaster, Kate. Disaster. What if I go back and ruin her?
- Kate Lethbridge-Stewart: For what it's worth, I think you bring joy.
- The Doctor: Ok... all of you... I need your help. Because something really weird keeps happening. Everywhere I land, a woman appears. Look. So, she is a comms officer in the planet Pacifico del Rio. She's someone's mum in Finetime. She's an ambulance. She's a portrait in 1813, and the list goes on. Planet Sloog, she's a Sloogma. Planet Varsitay, she is a Griffin. The Fivefold Configuration, she is a Bleet. So she's everywhere. She must be here. So I'm hoping that UNIT can find her and analyse her. She's always middle-aged, about so high, 60, slim, fair hair... What? What? What is it?
- Morris Gibbons: And right on cue.
- Cherry Sunday: If you're chasing after that Doctor man, I warnin' you, him is trouble!
- Carla Sunday: Everything is trouble. And I've decided it's about time I cause trouble for myself.
