David Tennant credited as playing...
The Doctor
- Tim Latimer: He's like fire and ice and rage. He's like the night and the storm in the heart of the sun.
- John Smith: [quickly and almost whispering] Stop it.
- Tim Latimer: He's ancient and forever. He burns at the centre of time and can see the turn of the universe.
- John Smith: [Panicked/Angry] Stop it, I said stop it!
- Tim Latimer: And... he's wonderful.
- Joan Redfern: Where is he... John Smith?
- The Doctor: He's in here somewhere.
- Joan Redfern: Like a story... could you change back?
- The Doctor: Yes.
- Joan Redfern: Will you?
- The Doctor: No.
- John Smith: You knew this all along and yet you watched while Nurse Redfern and I...
- Martha Jones: I didn't know how to stop you. He gave me a list of things to watch out for, but that wasn't included.
- John Smith: Falling in love? That didn't even occur to him?
- Martha Jones: No.
- John Smith: Then what sort of man is that? And now you expect me to die?
- Joan Redfern: I'm Sorry, John. But you wrote about it. The Blue Box. You dreamt of a blue box.
- John Smith: I'm not...
- [tearful]
- John Smith: I'm John Smith, that's all I want to be, John Smith. With his life... and his job... and his love. Why can't I be John Smith? Isn't he a good man? Why can't I stay?
- Martha Jones: But we need the Doctor.
- John Smith: Who am I then? Nothing...? I'm just a story?
- The Doctor: You're this doctor's companion, can't you help? What exactly do you do for him? Why does he need you?
- Martha Jones: Because he's lonely.
- The Doctor: [Horrified] ... And that's what you want me to become?
- John Smith: How can you think I'm not real? When I kissed you, was that a lie?
- Joan Redfern: No, it wasn't, no
- John Smith: But this 'Doctor' sounds like some, some romantic lost prince. Would you rather that? Am I not enough?
- Joan Redfern: No, that's not true, never.
- John Smith: I've got to go.
- Joan Redfern: Martha was right about one thing though; those boys, they're children. John Smith wouldn't want them to fight, never mind the Doctor. The John Smith I was getting to know... he knows it's wrong, doesn't he?
- John Smith: What choice do I have?
