Aito's face hardened for the briefest of moments at Viral's accusation, not at all appreciating it. Then, remember it was most likely not sincere he softened, letting out a sigh as he rubbed at his head. "I understand that, and I won't be conducting unwarranted tests anymore, I already said I wouldn't," the doctor responded, "If anything more needs to be done, you'll be notified beforehand and we'll need your permission to begin. I won't say that we won't have to run any more tests before this is done, because it may be a lie, so just understand that. Anything we do conduct is purely for your benefit." Leaving Viral to try and rest, Aito opted to do the same for himself, albeit in a different way. There was a plethora of questions currently demanding his attention, and he needed to find a way to address them relatively quickly. Viral's condition aside, he'd been asked to look into Shu, look into T'charrl, investigate what had been done to Yumi and even monitor Kiton's health as he recovered. Four patients, not overly intimidating numerically, but their conditions presented an array of problems for him. Mental, physical, emotional, cognitive, these were all issues for them in varying degrees, he had a lot of work for himself. Sitting down in a relaxed position, Aito closed his eyes and began an attempt to meditate, hoping to clear his mind and think clearly; doing this ought to provide Viral with privacy as well, despite only being a few meters away.

Takeshi had not expected to be the target of eraser-assault, and was quite surprised when he was struck. Wincing despite there being no pain he blinked just twice before looking at Vegeta defensively, rubbing a bit of smudge off of his forehead. That so wasn't necessary! But the guy was already going back to writing on the board, and he'd probably just ignore any attempts at talking, so on to T'charrl then. "Heh... Yeah, sorry about that. I guess everyone's trying to stay busy, even if they're in the hospital," the Saiyan remarked, coming over to the bedside and looking for a place to set Shu, "Like you are, studying and whatnot, you know? No one likes being made to sit around and do nothing." Hell, T'charrl would probably be out with them if he wasn't stuck here, poor guy. Finding a bit of space on the edge of the bed, Takeshi turned and eased Shu down to sit on it, smiling as he ruffled his brother's hair before stretching his bandaged shoulder carefully. "Oh, right! Uh we figured Shu was going to join your lesson, he wants to learn some stuff too. So if that's cool with you..."

"Whether it's 'cool' with me or not is irrelevant, you brought him here and so he'll learn," Vegeta responded without letting Takeshi finish, "It hardly matters to me if I have one student or ten, doesn't complicate my job any." It wasn't as though they were covering astrophysics or anything of the sort, this was very simple material that even Takeshi might be capable of teaching. In particular they were learning how to write at the moment, relatively simplistic sentences at that. With Shu now joining the lessons, he took a brief moment to grab another pad of paper and a pencil, bringing them over and handing them to the younger boy. T'charrl had already been instructed how to use them, but chances were Shu was a little clueless right now. "That thing in your hand is a pencil, and you use it to write," Vegeta explained, pulling one out of his pocket to show, "You generally hold one like this, but for your case and since you're learning, you can try like this," he added, holding the pencil enclosed in his palm. It was how a little child would use one, but for all intents and purposes Shu was basically that right now, so it would do. Going back to the board he pointed to the sentence there, and it read 'The cat is black'. "I just want you to try and copy this down you two, that's all. Shu? Have you been taught your alphabet yet? That means your letters."

Even when he was injured Kiton could strike fairly hard, no wonder his people used to be so feared. The power gap between them when he was healthy was likely massive, she'd never have a chance at really beating him then. But this wasn't a real fight again, it was more a show of technique than anything. Being knocked away hadn't deterred her any, and instead Sasha came right back in for a counter attack, bringing her leg up almost completely vertically in a jump before throwing it down, unsurprisingly being blocked by Kiton. Getting grabbed then she was thrown around by her leg, his tail coming around to strike her down again too. Reaching out she managed to not only grab his tail, but hold onto it and prevent herself from being tossed. Using the tail as leverage even, Sasha pulled herself back in and tried to knock Kiton to the ground, using her small frame as almost a battering ram to do so.
