Quote context

[...]

- You know about the machines?

- Yeah, I repair 'em.

- There's one chasing me now. A gunslinger.

- Gunslinger. Must be a model 404, maybe a 406. If he's a 406, he's got all the sensory equipment. It's a beautiful machine!

- He's after me!

- I don't doubt it.

- What can I do?

- There's nothing you can do. If he's after you, he'll get you. You haven't got a chance.

- There must be something!

- Fella, don't kid yourself. There are things you could try: Acid for his visual system, noise for his hearing.

- No matter what you did, he'll always be one jump ahead of you. You haven't got a chance!

- Yes, I do.

(Fast walking footsteps)

(Running footsteps)

- Help me!

- All right. It's all right.
