I wonder if he can use wind magic to help speed up his return to the academy, if not outright fly there. There's no way Slow is staying in Yolem city after hearing that. On another note, I'm a little suspicious of Maldini and how ordinary people have been evacuated in the area leaving only Royal knights stationed there.
With less than 10 chapters left, I hope we're not getting into a long political/coup plotline for this arc. I'd rather see some romantic progress before this ends.
