Headmaster Finch (Anthony Stewart Head): You poor child. Poor… thin child. Come inside. It’s nearly time for lunch.
The Doctor: It’s very well-behaved, this place. I thought there would be happy slapping hoodies. Happy slapping hoodies with ASBOs. Happy slapping hoodies with ASBOs and ringtones. {pleased with himself} Yeah? Yeah? Oh yeah! Don’t tell me I don’t fit in.
Rose: See? This is me. Dinner Lady.
The Doctor: I’ll have the crumble.
Rose: I’m so going to kill you.
Dinner Lady (Caroline Berry): What are you doing?
Rose: Calling an ambulance.
Dinner Lady: No need. She’s quite alright. screams come from inside the office. It’s fine. She does that.
Headmaster Finch: May I introduce Miss Sarah Jane Smith. Miss Smith is a journalist who is writing a profile about me for the Sunday Times. I thought it might be useful for her to get a view from the trenches, so to speak. Don’t spare my blushes.
Sarah Jane Smith (Elisabeth Sladen): Hello.
The Doctor: Oh, I should think so.
Sarah Jane: And you are?
The Doctor: Hm? Ah, Smith. John Smith.
Sarah Jane: John Smith. I used to have a friend who sometimes went by that name.
The Doctor: Well it’s a very common name.
Sarah Jane: He was a very uncommon man. Nice to me you.
The Doctor: Nice to meet you. Yes, very nice. More than nice. Brilliant.
The Doctor: Hello Sarah Jane.
Sarah Jane: It’s you. Doctor. Oh my god, it’s you isn’t it? You’ve regenerated.
The Doctor: Half a dozen times since we last met.
Sarah Jane: You look…. incredible.
The Doctor: So do you.
Sarah Jane: I got old. What are you doing here?
The Doctor: Well, UFO sightings, school gets record results. I couldn’t resist. What about you?
Sarah Jane: Same. They laugh. I thought you’d died. I waited for you and you didn’t come back, and I thought you must have died.
The Doctor: I lived. Everyone else died.
Sarah Jane: What do you mean?
The Doctor: Everyone died, Sarah.
Sarah Jane: I can’t believe it’s you. Mickey screams. Okay, now I can.
Rose: Who’s she?
The Doctor: Rose, Sarah Jane. Sarah Jane, Rose.
Sarah Jane: Hi. Nice to meet you. You can tell you’re getting older. Your assistants are getting younger.
Rose incensed: I’m not his assistant.
Sarah Jane: No? to the Doctor: Look at you, Tiger.
The Doctor: K-9! Rose Tyler, Mickey Smith, allow me to introduce K-9. Well K-9 mark III to be precise.
Rose: Why does he look so… disco?
The Doctor: Oy! Listen, in the year five thousand this was cutting edge. What happened to him?
Sarah Jane: One day just— nothing.
The Doctor: Well didn’t you try and get him repaired?
Sarah Jane: It’s not getting a part for a Mini Metro. Besides technology inside him could rewrite human science. I couldn’t show him to anyone.
The Doctor: Oo. What’s the nasty lady done to you?
Rose: No offense, but can you two just stop petting for a minute? Never mind the tin dog, we’re busy.
Mickey: You see what’s impressive is it’s been nearly an hour since we met her and I still haven’t said “I told you so”.
Rose: I’m not listening to you.
Mickey: Though I have prepared a little “I was right” dance I can show you later.
Sarah Jane: Did I do something wrong? ‘Cause you never came back for me. You just dumped me.
The Doctor: I told you, I was called back home and in those days humans weren’t allowed.
Sarah Jane: I waited for you. I missed you.
The Doctor: Oh, you didn’t need me. You were getting on with your life.
Sarah Jane: You were my life.
Sarah Jane: You know what the most difficult thing was? Coping with what happens next. No, with what doesn’t happen next. You took me to the furthest reaches of the galaxy, you showed me supernovas, intergalactic battles and then you just dropped me back on Earth. How could anything compare to that?
The Doctor: All those things you saw, you want me to apologize for that?
Sarah Jane: No! But we get a taste of that splendor and then we have to go back.
The Doctor: Look at you, you’re investigating. You found that school. You’re doing what we always did.
Sarah Jane: You could have come back.
The Doctor: I couldn’t.
Sarah Jane: Why not?
Rose: I wouldn’t touch it though. That Dinner Lady got all scorched.
The Doctor: I’m no Dinner Lady. And I don’t often say that.
Mickey: So what’s the deal with the tin dog?
Sarah Jane: The Doctor likes travelling with an entourage. Sometimes they’re humans, sometimes they’re aliens. And sometimes they’re tin dogs. What about you? Where do you fit in the picture?
Mickey: Me? I’m their man in Havana. I’m the technical support. I’m— pause Oh my god. I’m the tin dog.
The Doctor: You can spend the rest of your life with me, but I can’t spend the rest of mine with you. I have to live on. Alone. That’s the curse of the Time Lords.
The Doctor: Don’t forget to leave the window open a crack.
Mickey: What? He’s metal.
The Doctor: I didn’t mean for him.
Finch: And what of the Time Lords? I always thought of you as such a pompous race. Ancient, dusty senators so frightened of change and… chaos. And of course, they’re all but extinct. Only you, the last.
The Doctor: This plan of yours, what is it?
Finch: You don’t know?
The Doctor: That’s why I’m asking.
Finch: Well show me how clever you are. Work it out.
The Doctor: If I don’t like it, then it will stop.
Finch: Fascinating. Your people were peaceful to the point of indolence. You seem to be something new. would you declare war on us, Doctor?
The Doctor: I’m so old now. I used to have so much mercy. You get one warning. That was it.
Rose: The thing is, when you two met, they’d only just got rid of rationing. No wonder all that space stuff was a bit too much for ya.
Sarah Jane: I had no problem with space stuff. I saw things you wouldn’t believe!
Rose: Try me.
Sarah Jane: Mummies!
Rose: I’ve met ghosts.
Sarah Jane: Robots. Lots of robots.
Rose: Slitheen. In Downing Street.
Sarah Jane: Daleks!
Rose: Met the Emperor.
Sarah Jane: Gas mask zombies.
Rose: Anti-matter monsters.
Sarah Jane: Real living dinosaurs!
Rose: Real living werewolf!
Sarah Jane: The Loch Ness Monster!
Rose: Seriously?
Finch: Their lives are so fleeting. So many goodbyes. How lonely you must be, Doctor. Join us.
The Doctor: I could save everyone.
Finch: Yes.
The Doctor: I could stop the war.
Sarah Jane: No. The universe has to move forward. Pain and loss, they define us as much as happiness or love. Whether it’s a world or a relationship, everything has its time. And everything ends.
Mr. Finch: Forget the Shooty Dog thing.
The Doctor: Goodbye, old friend.
K-9 (John Leeson): Goodbye Master.
The Doctor: You good dog.
K-9: Affirmative.
Finch: You bad dog.
K-9: Affirmative.
Rose: What do I do? Do I stay with him?
Sarah Jane: Yes. Some things are worth getting your heart broken for.
