At first, Chloe tried to remedy the situation by stepping between Chrome and Jan. "That's enough now," she said sternly, but to no avail, and was about to continue when the sides of the train caved in with a loud, earsplitting noise and caused her to jump, slapping her hands over her ears. Then the train started moving and she stumbled away from the clearly-unhinged metal man. Her heart rate was leaping upwards, and she was starting to feel lightheaded. She envisioned someone turning a gas valve somewhere in her lungs and letting loose the chlorine.
When the train lurched into motion, she found herself backing into a wall. Stop freaking out. Stop freaking out. Behind a fog of panic she could hear Dan leaping out the window, and clumsily she poked her head out of the hole he'd left to see him fall, swearing, onto the ground below. Jesus! Maybe she should follow him before the train gained much speed. That way she wouldn't kill anyone by causing a chlorine gas buildup inside the train.
She turned toward Chrome and shouted; she didn't really know what had come over her. "Stop the fucking train, idiot! Do you see what you've done?! It's a fucking sword and you're threatening everyone's lives over it! So you better calm the fuck down, right fucking now, open some windows or let me get out before you continue your stupid petty little fucking fight over a piece of fucking metal!" Throughout the entire rant, there was a very visible (and smellable) cloud of chlorine practically pouring out of her mouth, and a little from her nostrils. "Do you fucking hear me! I will gas everyone in this god-forsaken fucking train car who has a normal set of human lungs!"
She was breathing hard by the end of it, catching her breath. Chloe was putting out more gas with every exhale, the heavy stuff gradually floating toward the ground but definitely making its buildup. Finally she continued, trying to seem calmer, but the shaking in her voice betrayed her: "Now you both listen here. I don't know shit about chemistry. But I'm not so sure that chlorine, iron, hydrogen and nitrogen are such a good combination. Also, helium here isn't reactive but she could turn us all into fucking ice blocks right now so drop your immature bullshit if you want to live."
