This episode is interesting. Although in the first few episodes we saw Himeno's family neglect her, when she disappears for three days, they all move heaven and earth to find her. However, there's someone else at home suffering, and they don't notice. The Disaster Princess, in her cruelty, uses the only person Mawato trusts to cause her more despair and thus gain more power. What I like most about this episode is that many of the mistakes of the past are now exacting a huge toll. This anime doesn't forget past wrongs and works on them to develop the problems and make them even bigger.
