“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.”

“I have lived a long life, and I have seen a few things. I walked away from the Last Great Time War. I marked the passing of the Time Lords. I saw the birth of the universe and I watched as time ran out, moment by moment, until nothing remained; no time, no space. Just me. I walked in universes where the laws of physics were devised by the mind of a madman. I watched universes freeze and creations burn. I have seen things you wouldn't believe, I have lost things you will never understand. And I know things, secrets that must never be told, knowledge that must never be spoken. Knowledge that will make parasite gods blaze! So come on then! Take it! Take it all, baby! Have it! You have it all!”

“How are you, Rory?' [the Doctor] asked.
I [Rory]... answered him. 'It's been odd being you.'
'Isn't it?' The Doctor's smile didn't quite reach his eyes.
'How do you cope?'
'Ah...' The Doctor picked away at a scrap of loose paint on the door. 'Well, I just get as close as I can to a happy ending, then I shut the door behind me and move on.'
I nodded.
We shut the door behind us and moved on.”

“I'll be a story in your head. That's okay. We're all stories in the end. Just make it a good one, eh? 'Cause it was, you know. It was the best. The daft old man who stole a magic box and ran away. Did I ever tell you that I stole it? Well I borrowed it. I was always going to take it back.”
