His mess

"So, you mean you will keep teaching her from now on?"

"Of course not. I have to go back to my library. I'm late anyway."

He told them how they needed to keep teaching her about her powers from now on, and how she needed to learn more about herself to realize how she could do many cool things.

There was a possibility that she might awaken her powers with some more knowledge about herself, what her powers were, or how she could do much more than what a mage could.

"You know much more than I do, so you should obviously be the one to teach her."

Besides, as he said, she might just be a genius. 

Just knowing about a few more things should be enough for her to realize the kind of strength that she had.

"You're just dumping her to me now? Aren't you the one that has taught her until now?"

Alex didn't mind teaching their little friend.
