Martha Jones: That wasn't very clever running around outside, was it?
The Doctor: Sorry?
Martha: On Chancellor Street this morning. You came up to me and took your tie off.
The Doctor: Really? What'd I do that for?

Martha: Why's everyone fussing about rain?
Julia Swales: It's going up.
Tish Jones: The rain is going up.

The Doctor: One thousand people. Suffocating.
Martha: Why would anyone do that?
The Doctor: Heads up. Ask them yourself.

Martha: You step on a butterfly, you change the human race.
The Doctor: Then don't step on any butterflies. What do you have against butterflies?

The Doctor: I'm Sir Doctor of Tardis and this is my companion Martha Jones.
Shakespeare: Interesting, that bit of paper. It's blank.

Martha: And why are you telling them that?
The Doctor: ...Dark Ages. If I tell them the truth they'll panic and think it's witchcraft.
Martha: Well what is it then?
The Doctor: Witchcraft.

Martha: You're taking me to the same planets you took her?
The Doctor: What's wrong with that?
Martha: Nothing. Just a bit of a rebound.

Martha: Are they selling drugs?
The Doctor: I think they're selling moods.
Martha: Same difference.

The Doctor: What if there no help coming. Not ever. What if there's just the motorway?

Solomon: We got stockbrokers, we got a lawyer. But you're the first doctor. Place gets classier by the day.

Tallulah: You've got that guy in a suit...
Martha: We're not together.
Tallulah: Oh sure you are. I've seen the way you look at him. It's obvious.
Martha: Not to him.
Tallulah: I should have realized, he's in to musical theatre. What a waste. Still you gotta live in hope.

Martha: I'm so glad to see you.
The Doctor: Yeah well you can kiss me later. You too Frank, if you want.

The Doctor: Time was, four Daleks could have conquered the world. But instead you're skulking away, hidden in the dark, experimenting...

Martha: No! You can't go.
The Doctor: I've gotta go. The Dalek's just changed their minds. Daleks never change their minds.

Professor Lazarus: That's an interesting perfume. What's it called?
Leticia: Soap.

The Doctor: I hate this suit. Something bad always seems to happen when I wear it.
Martha: It's not the outfit, it's just you.

The Doctor: Now. Well this building looks like his laboratory. Now we do tests.
Martha: Lucky I've just collected a DNA sample, isn't it?
The Doctor: Oh Martha. You're a star.

The Doctor: Martha, be careful. There may be something else onboard the ship.
Martha: Anytime you want to unnerve me, feel free.
The Doctor: Will do, thanks.

Riley: The wonderful world of space travel. The prettier it looks, the more likely it is to kill you.

The Doctor: Humans! You grab whatever's nearest and bleed it dry. You should have scanned!
Cath: It takes too long. We'd be caught. Fusion scoops are illegal.

John Smith: Funny how dreams slip away.

Martha: It's Monday, November 14th, 1913. And you're completely human. As human as they come.
John Smith: Hm. That's me. Completely human.

The Doctor: This watch is me.
Martha: Right. Okay, hold on.

Martha: Don't just stand there, move! God you're rubbish as a human!

John Smith: I'm John Smith. That's all I want to be. John Smith. With his life and his job. And his love. Why can't I be John Smith? Isn't he a good man? Why can't I stay?

John Smith: You're this Doctor's companion. What exactly do you do for him? Why does he need you?
Martha: Because he's lonely.

Beware the weeping angels. Oh, and duck. No really duck! Sally Sparrow. DUCK, NOW! Love from The Doctor 1969

Sally: But what does he do?
Larry: Just sits there, making random remarks. It's like we're hearing half the conversation. Me and the guys are always trying to work out the other half.
Sally: When you say you and the guys you mean the internet, don't you?
Larry: How'd you know?
Sally: Spooky, isn't it?

The Doctor: Fascinating race, the weeping angels. The only psychopaths in the Universe to kill you nicely. No mess, no fuss. They just zap you into the past and let you live to death.

Larry: “The angels have the phonebox”. That's my favorite. I've got that on a t-shirt.

Martha: It's a bit odd though. Not very one hundred trillion. That coat's more like World War II.
The Doctor: I think he came with us.
Martha: How d'you mean? He's from Earth?
The Doctor: Must have been clinging to the outside of the TARDIS. All the way through the vortex. Wow, that's very him.
Martha: What, do you know him?
The Doctor: A friend of mine. Used to travel with me.

Jack: Doctor.
The Doctor: Captain.
Jack: Good to see you.
The Doctor: And you. Same as ever. Although. Have you had work done?
Jack: You can talk.

The Doctor: You two! We're at the end of the Universe. Right at the edge of knowledge itself. And you're busy blogging!

Martha: Oh my god. You've got a hand. A hand in a jar. A hand. In a jar. In your bag.
The Doctor: But that's my hand!
Jack: I said I had a Doctor detector.

Jack: Still, we made it. Twenty-first century by the looks of it. Talk about lucky.
The Doctor: That wasn't luck. That was me.

The Doctor: I've been alone ever since. But not anymore. Don't you see? All we've got is each other.
The Master: Are you asking me out on a date?

The Master: You're public enemies number 1, 2 and 3. Oh, and you can tell handsome Jack that I've sent his little gang off on a wild goose chase to the Himalayas. So you won't be getting any help from them. Now go on, off you go. Why not start by turning to the right?
The Doctor: He can see us. disables the CCTV
The Master: Oh you public menace! Better start running. Go on, run.
The Doctor: He's got control of everything.
Martha: What do we do?
Jack: We've got nowhere to go.
Martha: Doctor, what do we do?
The Master: Run, Doctor. Run for your life!
The Doctor: We run.

Tom Milligan: How long since you were last in Britain?
Martha: 365 days. It's been a long year.

Tom: Story goes that you're the only person on Earth that can kill him. That you can kill the Master stone dead.

Tom: You've been in space?
Martha: Problem with that?
Tom: No, just, wow. Anything else I should know?
Martha: I've met Shakespeare.
