Cheyenne: Make believe it's nothing.
Frank: You've made a big mistake, Morton. When you're not on that train, you look like a turtle out of its shell. It's funny. Poor cripple talkin' big so nobody'll know how scared ya are.
Morton: I got on board within sight of the Atlantic, and before my eyes close I want to see the blue of the Pacific outside that window.
Frank: I know where you got on. I was there too remember? To remove small obstacles from the track you said. Well there were a few.
Cheyenne: Yeah, go on. Play, Harmonica. Play, so you can't bullshit.
Cheyenne's Lieutenant: Cheyenne. We thought we'd never make it.
Cheyenne: It's all right. You're right on time... to bury my escort.
Morton: Not bad. Congratulations. Tell me, was it necessary that you kill all of them? I only told you to scare them.
Frank: People scare better when they're dyin'.
Cheyenne: You deserve better.
Jill: The last man who told me that... is buried out there.
Harmonica: You know, Wobbles... I'm kind of mad at you.
Jill: Hey, you're sort of a handsome man.
Cheyenne: But I'm not the right man. And neither is he.
Frank: How can you trust a man that wears both a belt and suspenders? Man can't even trust his own pants.
Frank: Keep your lovin' brother happy.
Cheyenne: By the way, you know anything about a man going around playing the harmonica? He's somebody you'd remember. Instead of talking, he plays. And when he better play, he talks.
Cheyenne: They wanna hang me, the big black crows. Idiots. What the hell? I'll kill anything, but never a kid. Be like killin' a priest. Catholic priest, that is.
Jill: I could swear we're going to have that strange sound.
Harmonica: Right now.
Answer: 1) Jill is a prostitute from New Orleans. She seeks out a new life out West. Love is irrelevant here. 2) She was promised a country living, a family, and wealth. That's why she is looking not only for money or gold but also for the reason her family was killed. 3) So Leone can show her beautiful body. 4) She's saving her life. She's a prostitute and I guess she knows how to fake it. Remember: "There's nothing that can't washed off by a hot bath".
