Cat Room
It is, in fact, a cat room. Cat toys, cat food, everywhere...and there are also actual cats!! A big poster on the wall lists two rules: To not harm the cats (or harm anyone in the cat room), and to not take a cat out of the cat room. It seems to be a very expansive room with a lot of space, enough for all the cats to live in there comfortably.
Firestarter: "Alright, we're here," Firestarter says as she walks into the room, "Why did you want us to be here? Please tell me you're not doing something stupid."
Tarnish was right behind her.
Dax: Meanwhile, Dax and Rue sat on the floor, surrounded by cats as usual. Their faces were both unchanging as the two of them came inside.
"Close the door...and sit with us~"
Rue: "Yes. Sit."
Tarnish: He sat across from the two of them, Firestarter following suit, and with a cock of his head he straightened his coat.
"This feels like an interrogation, almost. Don't tell me I'm being trialed for my crimes! Just because of what I have done in the past, does not mean I'm associated with her!"
Firestarter: "Wh- What do you mean!?"
Rue: "This isn't an interrogation. This is....well."
He turns to Dax.
"I'm not explaining your nonsense for you."
Dax: "Hmm...well, I've invited you here because you're both insane and-"
Firestarter: "I'm not insane!" Firestarter immediately interrupts them, arms crossed. "Nobody gets me, that's it!"
Dax: "...Like I said, you're both insane," They continued. "And so are me and Rue! Or, to be more precise, we're both...quirky. Weird. So I declare that we form an alliance under the title of "Normal Gang". Yes?"
Tarnish: "Why, sure! I happen to love myself a good-"
Firestarter: "Nah."
Firestarter stood up. "Do whatever you guys want, but this bitch only rocks solo. All I need is me and my fire, got it!?"
Dax: "What does fire do for you? It doesn't purr or cuddle you like cats do," they reply. "This is a tactical friendship, you know. I'm trying to make sure you survive."
Firestarter: Looking down at Dax, she glares. "Course you wouldn't understand. It's not like everyone loses everything they have to fire."
She mumbles as she speaks, gripping her flamethrower. "The flames? Man, they're the only thing that remains at the end of the day. Everything else burns away. Whatever the hell you guys are doing? Yeah, probably not going to last long. It, too, will burn. My ass will, too, but at least fire will be able to soothe me. To comfort me."
Rue: "...You have interesting coping mechanisms, Firestarter."
His voice is laced with a hint of intrigue.
Firestarter: "I'm not coping with anything!"
She snaps at Rue, and it seems like her eyes almost begin to glow. "I lost my home to fire, my family, to fire...so I realized how powerful it was. Now look at me, the hunter instead of the hunted! I'll serve these flames and NOTHING ELSE until some motherfucker stabs me to death!"
Dax: ...Quietly, they tilt their head.
"You had a home? And family? Wow. I thought that was a rare thing."
The room instantly turns quiet.
Tarnish: "...B-Both of you, heed!" Tarnish interjects. "I believe that things have gotten a tad too serious-"
Firestarter: "Whatever, you bunch of losers," Firestarter snarls. "Have fun, I'm gonna go burn one of the rooms down."
She proceeds to leave.
Dax: "...Well, that went badly."
They shrug. "At least we have us three. I think that's enough, right Rue?"
Rue: ...Rue is processing what Firestarter just said.
"...Did she say she was going to burn one of the rooms down?"
Dax: "Oh. Yeah, she did. Is that important~?"
Tarnish: "Of course it is! I don't want this entire building to end up on fire!" Tarnish yells, getting onto his feet. "Normal Gang, deploy! We must strike down the chaotic force that is the lady of fire!"
