It seems to me Erica should have started to learn healing magic earlier. I wonder what made her start to learn it in the orginal timeline, as it couldn't have been for Harold's sake. I'm pondering this because if she had learned it, let's say, naturally, shouldn't she have begun her studies earlier, just like Harold was learning combat magic earlier (not just neo-Harold, but the original as well). Yet the initial impetus now was Harold getting injured. Well, who knows, since it was the game setting, it doesn't really matter.
