Doctor Who Season 1 Episode 13

The Doctor's Hologram: This is Emergency Program 1. Rose, now listen, this is important. If this message has 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: No!
The Doctor's Hologram: And that's okay, I hope it's a good death. But I promised to look after you, and that's what I'm doing. The TARDIS is taking you home...
Rose: I won't let you.
The Doctor's Hologram: ...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 Program 1 means I'm facing an enemy that should never get their hands 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 want to remember me, you can do one thing. That's all, one thing: (The hologram of the Doctor turns to stare at Rose) Have a good life. Do that for me Rose. Have a fantastic life.
