Senku was a bit distracted with looking through the microscope but then he got an uneasy feeling, like someone was watching him. Intensely. For some reason.

He turned his head and glanced around. "Hey Airavata." He greeted, when he solved the source of the intense stare.

He saw her crutches. He absolutely knew nothing about those repairs, nope, he definitely didn't consult on them even though he didn't break his promise exactly, he didn't do any repairs himself. He didn't even touch it!

As for his condition he was looking a little more normal, he wasn't confused or dragging, in fact his mind was back to being sharp. A couple of days' rest took care of what was going on with him. Magic healing saved him weeks of recovery.
