Brigitte's trauma is too egregious. I really hope it won't be solved too simply and only thanks to Yuri helping her. That would be too thick writing and would only work with a far lesser trauma, in my opinion. Of course it's usually easier to overcome anything if you have got support, but her situation more or less ignores everything around her, so what good would support do? Even if he was hugging her tightly when she sees flames, it seems to me she would again fall into her own inner world of trauma and the outside world would become meaningless. I can't imagine how they would even begin to help her. Since half of her trauma was caused by the grand betrayal by her own parents, that might be one option, but with such a monster of a father, what good could it do? I doubt her mom is any better.
