Dunno. Whatever Coco has to give maybe? Maybe Alaria has some humility now? Nothing tangible that much I can say.

I could say that Alaria might be on somewhat better terms with the staff, but the only one who I could think would really care for what Alaria did would be Lucilia, since she more or less is interested in Coco. And even than Lucilia never had much opinions on Alaria herself, though at least now it's better than before. Which is to say, Lucilia doesn't think Alaria is a violent bully.

As I said, I wasn't part of the development for Electromancy, and even if the two of you did work on it with each other I can't imagine that it improved to the next rank. Neither Alaria or Coco are that great with their magebloods, so all they'd have is practice. Maybe Alaria learns a neat trick using her spear and her magic.
