@RandomFanguy: From the way she reacted to the King commenting on how weak Fooly looked, it seems all but certain that her "panic" earlier wasn't because she was worried about Fooly being way over his head, but rather it was the kind of worry that a person may have about their parent/best friend/sibling/etc. embarrassing said person in front of their work colleagues by being themself. Because let's be honest, do you actually see Leo being perfectly okay with having Fooly accompany her to the royal court and introduce him as her new adventuring companion? She wouldn't get caught dead openly associating with him in front of her former comrades in the Royal Knights brigade; she already has to deal with the shit that one such comrade is pulling in her mad obsession with Fooly himself.
Meanwhile, Fooly's kicking ass because of course he is. He can read the language of abs better than anyone, and they tell him everything he needs to know.
@RandomFanGuy Well, maybe she was just worried about the later opponents Fooly's going to have to face, whereas the king was downright insulting her man right in front of her, so seeing Fooly prove the king wrong obviously made her do that :3 smug face
