that's what I'm thinking but because of his personality i think it was because he feared how much more powerful she was than.him.
I think you're right. He said he "saved" her and the flashback was of her exhausted to the point of having a nosebleed, so power aside I think he didn't want to see a kid push herself to death to learn magic
I think so too. He is just a dumbass that doesn't know how to avoid an undesired future with caution. She could be a natural that needs a trigger to awaken and that must be the problem.
i bet valerie is actually quite powerful but the magic dude was somewhat scared of her power or tried to protect her from herself hM
