[As distracted as she is by Artemisia's absence, and the fact that her throat still won't work properly, Mitsuru doesn't miss that there's something off about her classmate. But before she can pin down what, she sees that wave.

This isn't a greeting she's used to making, even on the best of days. So, when she raises her hand to wave back, the gesture is a bit slow, and hesitant. (And might well look even slower to him.)]
