DOCTOR: Why are you calling me madam?

YASMIN: Because you're a woman.

DOCTOR: Am I? Does it suit me?

YASMIN: What?

DOCTOR: Oh yeah, I remember. Sorry, half an hour ago I was a white-haired Scotsman.

DOCTOR: Come on, Ryan. Come on, Yaz. I'm calling you Yaz, cos we're friends now.

GRAHAM: Don't be daft. There's no such thing as aliens. Anyway even if there was, they ain't going to be on a train in Sheffield.

DOCTOR: There's this moment where you're sure you're about to die and then you're born. It's terrifying. Right now I'm a stranger to myself. There's echoes of who I was and a sort of call towards who I am. And I have to hold my nerve and trust all these new instincts. Shape myself towards them. I'll be fine. In the end. Hopefully. Well, I have to be, because you guys need help and if there's one thing I'm certain of, when people need help, I never refuse. Right? This is going to be fun.

DOCTOR: When people need help, I never refuse.

DOCTOR: We’re all capable of the most incredible change. We can evolve while still staying true to who we are. We can honour who we’ve been and choose who we want to be next. Now’s your chance. How about it?

DOCTOR: Bit of adrenaline, dash of outrage, and a hint of panic knitted my brain back together. I know exactly who I am. I'm the Doctor. Sorting out fair play throughout the universe. Now please, get off this planet while you still have a choice.

GRAHAM: And I know if she was here now, she'd tell us not to be so sad. You see, I can hear her saying to me, Graham, we had three glorious years, what're you complaining about? I'm complaining because I wanted more.

YASMIN: Have you got family?

DOCTOR: No. Lost them a long time ago.

RYAN: How do you cope with that?

DOCTOR: I carry them with me. What they would've thought and said and done. I make them a part of who I am. So even though they're gone from the world, they're never gone from me.

DEAN: Halloween's next month, mate. (throws salad at him) Eat my salad, Halloween!

GRACE: That was a big fall you had, love. We should get you checked out at A&E.

DOCTOR: No, no, no. I never go anywhere that’s just initials.

YASMIN: You don’t know your own name?

DOCTOR: Course I know it. I just can’t remember it. It’s right there, on the tip of my… What’s that?

RYAN: Tongue?

DOCTOR: Tongue! Smart boy. Biology. What did she call you? Ryan?

RYAN: Yeah. Ryan Sinclair.

DOCTOR: Good name. Are you a doctor, Ryan?

RYAN: No.

DOCTOR: Shame. I’m looking for a doctor.

GRAHAM: Go on, Ryan! You’re doing it, mate!

YAZ: What do we do when we get up there?

DOCTOR: Don’t worry, I’ve got a plan.

YAZ: Really?

DOCTOR: Well, I will have by the time we get to the top.

DOCTOR: Don't panic. Not the end of the world. Well, it could be the end of the world, but one thing at a time.

TZIM-SHA: A Stenza warrior wears his conquests. You may tell your children you were once privileged to encounter Tzim-Sha of the Stenza.

DOCTOR: Tim Shaw?

TZIM-SHA: Tzim-Sha.

DOCTOR: Tim Shaw?

TZIM-SHA: Tzim-Sha! Soon to be leader of the Stenza warrior race, conquerors of the Nine Systems.

DOCTOR: When you say soon to be leader, what are you now, the office junior?

GRAHAM: Eh? No, don't wind him up.

DOCTOR: I'm just a traveller. Sometimes I see things need fixing, I do what I can.

DOCTOR: Right, then, troops. No, not troops. Team. Gang. Fam? I'm distracting myself.

GRACE: You came crashing through that roof.

DOCTOR: I was thrown out of my TARDIS. Oh! I've lost my TARDIS! It was exploding and then it dematerialized! Don't panic. Not the end of the world. Well, it could be the end of the world, but one thing at a time.

GRAHAM: Are we supposed to understand anything you're saying?
