What were some of the Firefly stories you never got to tell?
He hemmed and hawed, “Should I tell you this?… Oh well, what’s he going to do, fire me?”
The original show was darker and this story was more in keeping with that tone. It opens with Mal and Inara fighting (as they do). Mal tells her she pretends to be a lady and wants everyone to bow before her and kiss her hand but she’s just a whore. Then the Reavers attack and take Inara. While trying to get her back they learn that she had something that would make anyone who had sex with her die. When they finally track down and board the ship they find all of the Reavers dead and Inara shaking
and traumatized. They take her back to the ship and Zoe guards her room. Mal tries to get in to see her and Zoe tells him he’s the last person Inara needs to see. He pushes past her, kneels before Inara and kisses her hand.
