The Doctor: Rose... before I go, I just want to tell you: you were fantastic. Absolutely fantastic. And do you know what? [Pause] So was I!

In the end I sort of though we created a companion who was so alive and dynamic and so wedded to the doctor that you’d need a whole universe to contain her in. The only way to get rid of her is to send her into a parallel world from which she can never return; otherwise she would stay with the doctor forever.

What Rose brings to the Doctor’s life is completion. It’s completing a circle – he’s male, he’s alien, he’s a traveler. Between the two of them together they complement each other and discover each other. And are in love with each other – absolutely, unashamedly, unreservedly.

Captain Jack: Rose, you are worth fighting for. [Jack kisses Rose passionately] Captain Jack: Wish I'd never met you, Doctor, I was much better off as a coward. [Jack kisses the Doctor the same way]

Wilf: God bless the cactuses! The Doctor: That's cactI. Alien: And that's racist!

Anything works, as long as you write it properly.

Writing isn't just a job that stops at six thirty... It's a mad, sexy, sad, scary, ruthless, joyful, and utterly, utterly personal thing. There's not the writer and then me; there's just me. All of my life connects to the writing. All of it.
