Yeah! I didn't really explain about Inara. I know I told you about her because she's gorgeous and so fancy and graceful. But she's a registered Companion. Captain says she gives Serenity a bit of "respectability" in a lot of the ports.
They're well trained and well paid. They get to choose who they sleep with and sometimes sex ain't even involved at all. And Inara is probably one of the best. I don't think I'm biased just because she's my friend.
