On the road again.

until the meds wear off anyway

Even missing a leg, Candlewick can't stay still; a bit relatable. He probably uses his gleam to susbstitute for it.

Guy can probably float if he wanted, but was never taught he could

A certain striped Mur probably could if she existed with him on a metaphysical level. That incident would be incredibly non-canon though.

Maybe Naeha could do it instead when he fully recovers.

Muu would have absolutely taught him, and the scholarship is fully intact with Naeha in charge. They are not letting a powerful fawn like that get away without a good and thorough education of his abilities.

And again, he is also 4 years old, and school was out fo rhte season due to being so close to Witchburning and the end of the year. If I ever do any future stuff, he'll definitely have more control and finesse.

Would Cathy be a good teacher?

Yes, but she wouldn't be as fun as Muu. She'd be more strict and her tone could sometimes be unsettling to others.

Unsettling? to a fawn that was raised by untold horrors, and defeated said untold horrors from beyond the galaxy in the matter of a night? sounds like a battle of wills, lol
