"You know this ain't gonna work forever, right?" groans the Commander, his voice rough and with a strange, almost otherworldly undercurrent to it. He stares at his friend, eyes wide, essentially his only remaining semblance of humanity.
"I know," confesses Jimmy, watching over the strapped-down figure. All of his skin seems to have a mind of its own, constantly shifting and changing underneath the restraints, squirming even as MCBC tries to remain still.
"It's alright," he offers, voice sounding more and more like he's lying about it. The pitch shifts oddly, the undercurrent becoming more apparent and sounding like a chattering noise in the back of his throat. It's almost a growl; a freakish, alien growl that quivers as he lets out a whimper, clearly in pain as the infection crawls further across his skin, looking like the abstract shape he's becoming could cleave his very body in two with the inhuman contortions he's transforming into.
"I can't do it."
"You have to, Jimmy, I… I can't hurt you, too. Not after everything else. Please…"
Jimmy's eyes lower to the floor, trying his hardest to ignore the desperation on his Commander's increasingly monstrous face. But he's becoming something he never was, and not just physically, either. When it first took over fully and he tore holes in the Battletram, nobody was capable of stopping him as he rended flesh from bone and steel from support beams with no discrimination whatsoever. Jimmy, the only piece of metal capable of staying out of his path, was one of the only things not ripped apart in the carnage. And when he finally had the courage to leave the lab, having to try his hardest to ignore the cries and pleas for help from his fellow Aquabats, he found the atrophied, deformed figure of the Commander sobbing in a heap on the floor, surrounded by smears of blood and having a bout of humanity again. It comes and goes, MCBC occasionally just resorting to strange gurgled noises or spasms and aggression again. Jimmy knows it can't last any longer, feeling he'd be more comfortable with the option he's presented with and knowing that his best friend would, too - to leave him all alone after the Commander inevitably destroyed him would be a far worse fate for him, although the robot considers the opinion that it might be a better option for himself.
"It'll be okay," Jimmy coos soothingly, trying to reassure the pair of them as tears roll down the Commander's face. "Just… Shh, it'll be okay."
It doesn't take long before the injection he had to force through the tough skin on the Commander's arm starts to work. The robot lowers his head over the now still figure, his breathing coming to a peaceful stop, and wonders if decommission would be more favourable than trying to deal with the fact he just killed not just his only living friend, but also his dearest.
