“The Doctor: [hologram, speaking towards the console] This is Emergency Programme One. Rose, now listen, this is important. If this message is activated, then it can only mean one thing: we must be in danger, and I mean fatal. I'm dead, or about to die any second with no chance of escape.
Rose Tyler: No!
The Doctor: And that's OK, I hope it's a good death. But I promised to look after you, and that's what I'm doin'. The TARDIS is takin' you home.
Rose Tyler: I won't let you.
The Doctor: And I bet you're fussing and moaning now, typical. But hold on, and just listen a bit more. The TARDIS can never return for me. Emergency Programme One means I'm facing an enemy that should never get their hooves on this machine. So this is what you should do: let the TARDIS die. Just let this old box gather dust. No one can open it, no one will even notice it. Let it become a strange little thing standing on a street corner. And over the years, the world will move on, and the box will be buried. And if you wanna remember me, then you can do one thing. That's all, one thing.
The Doctor: [hologram turns to face Rose, and with a full voice] Have a good life. Do that for me, Rose. Have a fantastic life.”

“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.”

“I’m sorry if I’m not flirting with you. I’m kind of spoken for.”

“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.”
