"Oh, do cheer up, Robert."
"I can't. I feel physically incapable of cheering up."
"Look on the bright side!"
"There's a bright side?"
"We're in an underwater city, brother, think of that. Think of the implications of such a tight and confined society. Also, that little girl we saw. Wasn't she fascinating?"
"She rather scared me, actually."
"You're hopeless. Or, really, DeWitt is hopeless."
"No, Ros, there was hope this time. He got so far…"
"Don't feel bad for yourself, feel bad for him. Bleeding to death is never a pleasant fate."
"How would you know?"
"Now, don't be insolent, brother. I have an imagination. How else do you think I got a city to fly?"
"I figured it had more to do with science."
"Yes, well. It's funny, though, I thought the girl had more medical knowledge than to let him just die."
"She was distracted by Songbird's death."
"Probably."
"He just came so far."
"Yes, brother, you've said that over a dozen times in the last hour. Shall we leave now?"
"If you insist."
"I'd rather we gave the whole thing up, myself. But I do love you. So I will insist on your behalf."
"I love you too, Ros."
"I'm sure I love you more."
"Is this about my threat again?"
"Maybe. You were rather exploiting the fact that I can't live without you."
"I know."
"You're colder than I give you credit for, brother. You do impress me from time to time."
"You impress me on a daily basis."
"You're also more easily impressed than I gave you credit for."
"I love you."
"Let's go."
