Considering how Blaster treats you and the other Autobot Cassettes, some part of you felt bad for how Soundwave must be treating his own Cassettes.
Decepticons have no sense of loyalty; they're just killing machines with sadistic tendencies who only look out for themselves.
So, when you managed to corner Frenzy on the battlefield, it didn't surprise you when he shot at the ground beneath you, causing what must be a cave-in or something similar.
Such underhanded tactics are all Decepticons can do, and it seemed to be some karmic justice when the ground continued to give way, causing Frenzy to fall into the hole he'd just created.
What does surprise you is just how badly you react to something blocking the exit, but more importantly, blocking the light.
It almost seems as though all the air has been sucked out of the small space, and your engines splutter as your vents close up, causing you to begin overheating. It's not enough to be dangerous, but it is enough to be uncomfortable, and to add to your quickly growing unease.
You hate the dark, you hate small spaces, it's not fair, you haven't done anything wrong, you don't deserve to go in the box, it's not fair, it's not fair, it's not-
"Uh... You okay there? I know we're supposed to be killin' each other and all dat, but you keep muttering about a box, and I need'ta know if you're just crazy."
Frenzy. That's right, Frenzy's in the box with you. Why is Frenzy in the box, too? Oh. That's right, you're not in the box, are you? You're just in a cave-thingy caused by Frenzy shooting the ground.
You're not in your alt mode, you can move, you can speak, you can open your optics-
"Helloooo? Luna-1 to the Autobot scum...?" Frenzy waves his servo in front of your faceplate, his red optics bathing you in dim crimson light, and when you finally open your blue optics, they cast him in dim sky-blue light.
Why isn't he freaking out? Does Soundwave not put his misbehaving cassettes in a box? Whatever a Decepticon does to punish bad cassettes must be even worse, even if you can't think of anything worse than the box.
"What?" Frenzy blinks at you, realisation dawning on his faceplate.
It's almost as though he read your processor, and you're tempted to start trying to imagine walls around your thoughts before you realise the echo surrounding you is your voice.
You asked him what Soundwave uses instead of the box.
Why does he look so horrified...?
