Rising early in the morning, he made sure to keep himself close to the hospital, moving and positioning himself as needed to help with any breakthroughs with his mother, but nothing had come up yet. He had people working around the clock for her. Himself included, he was surely ready to know the idea that he would be able to figure everything out to keep her alive as long as possible. Maybe they would have to amputate the leg completely? Maybe, but then he'd have to prepare the puppet limb for her to move around. Nothing would change the fact that she was in pain and he wanted to help her as best he could.
Though, he took his mind off of it for the time being, ordered against himself to train in some classes to help the next generation of medical practitioners. And Mikasa would be overlooking it, or so he thought. He felt that she trusted him, but maybe this was because she kept him on a relatively short leash. Knowing the Minamoto boy wasnt daft enough to overstep his boundaries or to betray her trust for fear of the power she held within. So there he would stand in the midst of the building. The Class room was read with his name on the chalk board, with the Title, 'Intro to the Medical Branch', he would be enthusiastic to see who would breach the threshold and begin down the path of saving lives with their minds more so than their brawn.
He made sure to make posters and plaster it upon the announcement board in the academy that there was a class in the hospital directly. This would be a simple class, enough to get their brains in gear and enough to know the ideas of what would be asked of them by joining the ranks. As well as a brief understanding of each level in the Medical Group.
