“I'm a Helian, and you're an Arcan. We're just made that way. I don't think we would ever be able to really understand each other.”

“You're what my art's all about, Marcus. We see something and think we know it, understand it, but really we're lucky if we ever understand any more than a small piece about anything. The infinite of the universe is in each one of us. You're grace, faith. Hopelessness, despair. Violence and anger. Beauty. You overwhelm me.”

“But don't go thinking that I'm critical of you, Anton, because really I'm not. Not a bit! It's just that you're not here. I'm alone and I'm frightened and you're not here. And you're not ever going to be here for me.”

“Simon: You're in a dangerous line of work, Jayne. Odds are you'll be under my knife again, often. So I want you to understand one thing very clearly: No matter what you do or say or plot, no matter how you come down on us, I will never, ever harm you. You're on this table, you're safe... 'cause I'm your medic. And however little we may like or trust each other, we're on the same crew. Got the same troubles, same enemies, and more than enough of both. Now, we could circle each other and growl, sleep with one eye open, but that thought wearies me. I don't care what you've done, I don't know what you're planning on doing, but I'm trusting you. I think you should do the same. 'Cause I don't see this working any other way. River: Also, I can kill you with my brain.”

“My husband and I see each other only on weekends, and generally get along well. We're like good friends, life partners able to spend some pleasant time together. We talk about all sorts of things, and we trust each other implicitly. Where and how he has a sex life I don't know,and I don't really care. We never make love, though -- never even touch each other. I feel bad about it, but I don't want to touch him. I just don't want to.”

“I want us to be able to live our lives and experience things apart from each other, but at the end of the day, I would want to be able to fall asleep knowing that our lives are intertwined in a way that only we can understand.”
