Ruby: Is it safe? What if I step on a butterfly or something?
Doctor: That is not going to happen. Who steps on butterflies?

Poppy: We're not supposed to be like this. Did we grow up wrong?
The Doctor: Nobody grows up wrong. You are what you are and you are wonderful and magnificent.

Ruby: I can't just call you Doctor. I want to know your name.
Doctor: That's kind of complicated because I was adopted and the planet that took me in were posh and used titles like Doctor, Rani, Conquistador. Say Doctor for 1000 years and it becomes my name.

I am the last of the Time Lords. And I am so glad to be alive.

It's strange, you were abandoned like this lot. If things connect, you are connecting like crazy.

The Doctor

Ruby: Ten minutes ago, you said genocide. Your people are gone.
Doctor: Yeah.
Ruby: How do you go on?
Doctor: For days like this, Ruby Sunday. I don't have a people. I don't have a home. But I don't have a job either. I don't have a boss or taxes and bills to pay. I don't have a purpose or a cause or a mission, but I have freedom. So I keep going to see the next thing and the next and the next. Sometimes it looks even better through your eyes.

The Doctor: Come on then, you lot. Places to go!
Yaz: When you say 'Places to go!' where you thinking? Where to next?
The Doctor: I was thinking... EVERYWHERE!

The Doctor: It's shutting down the wi-fi, the phone signals... Woah, that Dalek just shut down the whole of Britain's Internet.
Graham: What, on New Year's Day? When everything's shut and everyone's hung over?
Ryan: What a monster.

Oh, you're good, Ryan's Dad. You're almost making up for your parenting deficit.

The Doctor: How are you feeling, Lin?
Lin: Shaky
The Doctor: I'm not surprised. You will for a while. But you kept fighting it, thank you. Take these. Three a minute for four minutes. Don't take with alcohol, you'll grow an extra head. That was an embarrassing party.

Yaz: How'd it go? What happened?
Ryan: Did you get rid of it?
The Doctor: Not quite.
Yaz: How much 'not quite'?
The Doctor: Not at all. Slightly riled it and let it get away. And now it's in a tank, trying to summon the fleet.

Dalek: Humanity will surrender!
The Doctor: They really won't, trust me. I've seen them in action. They've fought off so many things, including the worst of their own people. They're really stubborn. Have you not worked that out yet?

Doctor Who Quotes

There's a horror movie named Alien? That's really offensive. No wonder everybody keeps invading you.

The Doctor

The Doctor: It's a risk.
Graham: Oh, like none of our other trips have ever been risky.
The Doctor: I have apologized for the Death Eye Turtle Army! Profusely.
