"That's not even how you have babies!" Howled the irate youth, burying his face in the bed in the closest approximation he could of the headdesk that inane complaint so desperately deserved. However, much to his frustration, the girl didn't seem to be listening, instead going on at length about how he'd ruined her life, how all she'd ever wanted was to escape and go back to her father, and how-
Wait... she WHAT?! But... but they said...
She was supposed to be... you mean she wasn't... like me?!
And I... I...
They... they tricked me! They tricked me and made me-
"Oh god, I'm ruined, I'm ruined. Soiled. By a complete stranger, no less!" The girl sobbed, apparently heartbroken. The bedsheets Myrion had wrapped around himself fell away from him as his grip went limp, his eyes wide in shock as a horrified realization overtook him. Memories flashed through his mind of a white room, of joyous excitement at the prospect of running his own experiment, of plans drawn up and materials requisitioned and procedures performed, new inventions created and connected and assembled and...
...And a girl with oddly colored blue hair, lying prone before him as machines - his machines - transformed her body from the inside out, improving it in every way he could think of, turning her into a testbed for living armor and weaponry.
Those bastards! They told me she was an artificial test subject, no different from me! And I, fool that I am, believed them! They lied, lied, lied! And... and I didn't even think to question it!
Abruptly casting an indignant glare in Myrion's direction, the girl pointed directly at him, placing blame where it was, perhaps, most justly due. Even if her reasons for accusing him were all wrong, even if she didn't seem to know what he had done to her, she had every right to sling guilt and shame upon him. And so, even as she did, he merely lowered his head in silent guilt, any and all objections he himself might have raised dying before they left his throat. "You did this, so take responsibility!" She commanded. Myrion, try though he might to act mature, was still a child. As such, coping with the guilt of having single-handedly ruined someone's life was far more than he could really bear to contemplate. It was hard enough not to cry. It was even harder not to confess his guilt on the spot and plead for forgiveness. But still, he hesitated, realizing that, given her impulsive demeanor and willingness to break out of her cell, she'd probably have no hesitation in killing him if she found out he was responsible for her current misfortune. As such, he had to keep it secret. He had to keep a straight face, and say nor reveal nothing. He'd even play along with her ridiculous illogic, if it meant concealing his true guilt.
Myrion, you pathetic, festering cur! This is all your fault. You did this to her! She was just a normal girl, and you turned her into... into this!
"Get me out of here and I'll forgive you! It's the only way!"
Myrion gave a quiet hiss of annoyance. He had been perfectly happy with his work, and was loathe to cause even more unrest within the foundation that had created and housed him, and had, if unintentionally, given him the abilities he now cherished. He also had little will to go against his father. But, at the same time, if this was the true magnitude of his guilt, then...
"Tch. Fine, I guess if it has to be this way, I'll help you out. The outside world may contain interesting research subjects of its own, I suppose. So... there, are you happy? Will you stop freaking out now?"
