“Rose Tyler: Can't you come through properly? The Doctor: Then the whole thing would fracture. The two universes would collapse. Rose Tyler: So?”
“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.”
“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.”
“Cyber Leader: Daleks, be warned. You have declared war upon the Cybermen. Dalek Sec: This is not war - this is pest control! Cyber Leader: We have five million Cybermen. How many are you? Dalek Sec: Four. Cyber Leader: You would destroy the Cybermen with four Daleks? Dalek Sec: We would destroy the Cybermen with one Dalek! You superior in only one respect. Cyber Leader: What is that? Dalek Sec: You are better at dying.”
“Rose: Who are you then? Who's that lot down there? [The Doctor ignores her] I said who are they?!The Doctor: They're made of plastic. Living plastic creatures. They're being controlled by a relay device on the roof. Which would be a great big problem if- [he pulls a bleeping bomb out of his coat] -I didn't have this. So I'm gonna go upstairs and blow it up. And I might well die in the process. But don't worry about me, no. You go home, go on! Go and have your lovely beans on toast. [suddenly serious] Don't tell anyone about this 'cos if you do, you'll get them killed. [closes the door] [opens it again] I'm The Doctor, by the way. What's your name?Rose: Rose.The Doctor: Nice to meet you, Rose. [holds up the bomb, shaking it slightly while grinning.] Run for your life!”
“I am the Bad Wolf. I create myself. I take the words. I scatter them ... in time, and space. A message to lead myself here.”
