THE DOCTOR: Okay, now back to the real problem: How to stop my impending death? (thinks) I've got it! Russel T. Davies said I would fight water monsters next, so I can't die if I don't fight any water monsters!

ADELAIDE BROOKE runs in.

BROOKE: Help! Water monsters!

THE DOCTOR: Oh, give me a break! Wait a minute. Who are you?

BROOKE: I'm Captain Adelaide Brooke. (holds out hand)

THE DOCTOR: Wait. The Captain Adelaide Brooke? (to himself) Oh, no. I have to-but I can't-it's a fixed point-what can I-? (notices BROOKE's hand; shakes it) It's an honor to meet you.

BROOKE: Thank you.

THE DOCTOR: Now, what's this about water monsters?

WATER MONSTERS enter. They are dressed as thugs and carry plastic water bottles which they occasionally swig from.

WATER MONSTER #1: Yeah!

WATER MONSTER #2: We're the Water Monsters!

THE DOCTOR: Uh, context?

BROOKE: The Water Monsters. They're a rap duo that just showed up and have been causing all kinds of trouble.

THE DOCTOR: Oh, well, that's good. Because I was worried that I'd be facing, like, actual water monsters from space.

WATER MONSTER #1: And we're from space!

THE DOCTOR: Of course you are. (to BROOKE) But look, you're Captain Adelaide Brooke. Surely you can oust a couple of unruly rappers?

WATER MONSTER #1: (draws gun): We're gonna kill everyone on this planet!

WATER MONSTER #2: (draws knife) Yeah!

THE DOCTOR: Well, that escalated quickly.

BROOKE: Is there anything we can do, Doctor?

THE DOCTOR: Sorry, no. This a fixed point in time.

BROOKE: What does that mean?

THE DOCTOR: Millions of people have been asking themselves that for years. But the upshot is that if you don't die here, history changes.

BROOKE: Okay. I can accept that.

THE DOCTOR: (to himself) What bravery...She can accept her own death without so much as...Wait a minute! (to WATER MONSTERS) If I helped you guys out with your music, would you go away?

WATER MONSTER #1: How would you do that?

THE DOCTOR: I could lay down some backing vocals for you. I'm a very good singer.

WATER MONSTER #2: When would you do that?

THE DOCTOR: Later. Maybe much later. But I will do it.

WATER MONSTER #1: Works for me.

WATER MONSTER #2: Yeah, same here!

WATER MONSTERS exit.

BROOKE: What have you done?

THE DOCTOR: Okay, so Adelaide doesn't get killed by a couple of rowdy rappers on Mars. So what? The point is, I now know that I have the power to rewrite history!

BROOKE: But no one should have that kind of power!

THE DOCTOR: Uh, am I bovvered?

BROOKE exits.

THE DOCTOR: I don't know why you're so upset. I mean, I just saved your life. I may be a power-tripper, but at least I saved your-

SOUND: Gunshot.

THE DOCTOR: Uh, Captain Brooke? (a beat) Don't you think maybe you're overreacting?
