Remember, Mina's a shapeshifter, Nick's an immortal reality warper.
"Alright, so in order to allow this court full disclosure, as Nick here said, he doesn't necessarily have an Ess'Vee speaking directly to him. Most of us have various levels of connection with our Ess'Vee, ranging from outright possession, to nothing at all." Remi coughs. "Now, my position of argument is that, as this court should know, those colloquially known as Mad Geniuses have only one speciality. Now, my comrade has demonstrated one of her abilities, that of complete and utter biological control over her body. This young boy right here, which I can prove if this court allows it, is immortal, through means of resurrection after his death, and is an extremely powerful reality warper. I am able to summon a gun, which holds some...special properties, but I assume that this court would not allow me to draw a weapon. These powers? They have absolutely no connection to each other. Now, you might be saying that Doctor Hematite might be able to grant powers, but I ask you this in return, why on Earth would he grant them to a lawyer, a child, and a random woman? In short, it makes no logical sense that Dr. Hematite made these powers, and granted them to us, lying to literally everyone, rather than his actual specialty, which is extradimensional shenanigans, tying beings to our bodies, which granted us actual abilities. Mina, Nick, you can return to your seats for now, if you'd like. I apologize for using you as a visual aid."
Remi's eyes turn Red. His Cheshire Cat smile returns in full force.
"Now, I realize this might still seem utterly improbable. As such, I am opening myself up to questions, rather than Remi answering everything, to prove the truth of the matter." He turns to the lawyers. "Ask me anything you want about this, and I'll provide an answer, to the best of my ability. Remember, I'm possessing this body, so I'm not omniscient, at least right now. This is a once in a lifetime opportunity, so cross-examine me carefully."
