DOCTOR: You betrayed me. Betrayed my trust, you betrayed our friendship, you betrayed everything that I've ever stood for. You let me down!

CLARA: Then why are you helping me?

DOCTOR: Why? Do you think I care for you so little that betraying me would make a difference?

MISSY: (as Maggie Smith) I am in charge.

DOCTOR: Well, who's in charge of you?

MISSY: I'm in charge of me.

DOCTOR: Well, who repairs you? Who, who maintains you?

MISSY: I am programmed for self-repair. I am maintained by my heart.

(Missy takes the Doctor's hand and places it on her bosom.)

MISSY: Is everything in order?

DOCTOR: Who maintains your heart?

MISSY: My heart is maintained by the Doctor.

MISSY: Hello. I hope you're well. How may I assist you with your death?

DOCTOR: Well, there is, er, no immediate hurry. We're just, er. We're just...

CLARA: Browsing.

DOCTOR: Yeah, yeah, browsing.

MISSY: Please, take all the time you need. At 3W, you always have the rest of your life.

DOCTOR: Who maintains your heart?

MISSY: My heart is maintained by the Doctor.

DOCTOR: Doctor who?

CLARA: Oh, I’d say I’m sorry but I’d do it again.

* (Clara falls to her knees and cries.)*

DOCTOR: We're here to get your boyfriend back from the dead. So buck up and give me some attitude!

DOCTOR: That won't do.

CLARA: What won't?

DOCTOR: You won't. Look at you. I need sceptical, clever, critical. I don't need mopey. It puts years on your face. What if people see us together? It looks like you've been melted.

CHANG: We call it dark water. Only organic matter can be seen through it. I keep saying they should use this stuff in swimming pools.

DOCTOR: Why?

CHANG: Think about it.

DOCTOR: I am thinking about it. Why?

MISSY: You felt it. (sighs dramatically) Surely you did.

DOCTOR: Two hearts.

MISSY: And both of them yours.

DOCTOR: Clara. Clara... Clara! I've got to get to Clara!

MISSY: Oh, "Clara, Clara, Clara!" I should shoot you in a jealous rage – now, wouldn't that be sexy?

MISSY: I've turned the lift off, though.

DOCTOR: I presume you have stairs.

MISSY: (to herself) Well, I'm not a Dalek!

DOCTOR: What's so good about seeing a volcano? It's just a sort of leaky mountain.
