[In mid-air]

(In mid-air)

DOCTOR: Listen to me, Karvanista. If you think you have won this little skirmish, you are very much mistaken. Do not imagine for a second that you have got the better of us. Right, Yaz?
YASMIN: Oh, yeah. We are totally in command.
KARVANISTA [OC]: Is that right? Cos from where I'm hovering, you seem to be handcuffed and footlocked to a gravity bar, which in 79 seconds will release you into the boiling acid ocean directly below, where your bodies will instantly disintegrate. Even if you survive that - which you won't - in four minutes' time the entire planet will be engulfed by a nearby giant red star. Oh, and if you try and escape, my Kill Disks will blast you to pieces.

(Flying machines with twirling blades.)

KARVANISTA [OC]: Meanwhile, I am now far away, travelling towards what will in future be known as the final hours of planet Earth.
BOTH: What?
KARVANISTA [OC]: Don't worry. You'll be long dead.
DOCTOR: Oh. I must admit, Yaz, I can't help feeling that some of this is my fault.
YASMIN: Some? All of this is your fault.
DOCTOR: What d'you mean?
YASMIN: Accidentally blowing up Karvanista's droid guards when we were trying to sneak into his operations base unnoticed?
DOCTOR: It's very temperamental, Nitro-9.
YASMIN: Suggesting we escape his base by air-surfing on this gravbar?
DOCTOR: How was I to know that force shield would reboot at the exact moment we were heading towards it?
YASMIN: And when we got captured, you had to mention the two sets of cuffs in your pocket.
DOCTOR: Two words, Yaz, Trapezium Seven.
YASMIN: Okay.
DOCTOR: Trapezium Seven. That high-gravity circus workshop. Who were the top two in the class? Ready?
YASMIN: No!
DOCTOR: Me neither. I love being not ready. Three, two, one. Alley-oop.
