- Sullivan: Could I made you blush ? Could I embarrass you ?
- Friendship: Can't blush. Got no liquids.
- Sullivan: Oh, you can't blush ? You've got no shame. You know that Darwin once said that blushing is the most human of responses. It doesn't occur anywhere else in the animal kingdom. It requires self-consciousness. It speaks of things that you may have admitted to yourself but you won't admit to others.
- Friendship: It's all to do with sex. Feeling flurried. Tingling. Glow. Enough to attract, not to intimidate. Blushing gives you away. It reveals your desires, your inadequacies. It's always sincere. That's why I can't blush. I can't be sincere.
- Friendship: What will happen when your machines become intelligent? When they become autonomous? When they have private thoughts? You humans look down on your machines because they're man-made. They're a product of your skills and labour. They weren't even domesticated like animals were. You see them simply as extensions of yourself, of your own will. I can't accept that. I can't accept subhuman status simply because I'm a machine based on silicon rather than carbon, electronics rather than biology. If I sound fanatical, it's because I've been trapped in a time warp. In a world where the full potential of machines hasn't been guessed at. A world where I have to wear a human disguise to be accepted? I came here too late. It will all end before the computers that already control the fate of the world have reached the point where they wanted to survive.
