Joss is Boss.
Ebony hurried towards the cargo bay, Wash and Zoë close behind her. As they reached the top of the stairs, the scene below them became visible. Serenity's crew stood together on the further side of the bay, facing the stairs. The girls were stood facing them, a clear gap between the groups.
"You're gonna tell us what in the hell is going on!" Came Mal's voice. Zoë recognised his tone. It was the tone he used when he didn't understand a damn thing that was going on, and that fact had made him angry. As she hurried past Ebony and down the stairs, she could see a little better what had caused this. Simon was clutching his arm where Nova had grabbed it, Kaylee at his side, and Jayne was half leaning on Shepherd Book, leaning forward as though winded. She picked up her pace, rushing to Mal's side, Wash following her. Ebony went straight to her friends.
Nova was stood directly opposite Mal, and Zoë recognised her stance as one that could become defensive, or a fighting stance, in a moment.
"Mal, what…?" Wash started, but was interrupted by Jayne.
"Little bitch kicked me clear twenty feet!" he yelled, trying to start forward and being restrained by the preacher.
"You grabbed me! What reaction d'you expect if you grab someone from behind, you twat?" she shouted back, causing everyone to begin yelling at each other at once, even if they were only trying to ask what was going on. The unintelligible noise went on for some time, with River clutching her head, until Mal fired his gun into the air, bringing a loaded silence made more prominent by the distant rumble of the engine. Finally, Mal managed to spit out a sentence.
"Who are you?" he demanded, staring at the girls, who at the sound of the gunshot had all assumed fighting stances.
"I'm Nova," she replied. "The Vampire Slayer."
