Everyone is acting like she's the worst councilor so far, but she's literally the only one who hasn't wanted to beat him to a pulp. On top of that, she's the only teacher (aside from the first one we saw interacting with the principle way back in the first chapter) so far who's even come close to seeing him for who he truly is. Honestly, if it weren't for her particular knack for misfortune, she'd probably be his greatest and most effective advocate among the teachers (if she stayed on as staff, that is).
