Erika and Sakaki manage to escape from under Sensei with her mother's guidance. Apparently, she's been making preparations, little by little, for Erika to run away one day. Erika learns of thoughts and feelings she didn't know her mother had.
After making contact with Mikado and the others, Erika tells them that she wants Sensei to stop doing the work they do, not just herself. Mikado decides to help, but it seems that Hiyakawa can't understand Erika and Mikado's feelings.
My husband hasn't come home, so I asked
 the two of them to show me here.
لم يرجع زوجي للمنزل، لذا طلبتُ
منهما أن يرشداني إلى هنا
Mi esposo no ha vuelto a casa,
así que les pedí que me trajeran.
Mi marido no ha vuelto a casa,
así que les pedí que me trajeran.
Mon mari n’étant pas rentré,
je leur ai demandé de m’amener ici.
Meu marido não foi para casa, então pedi
que os dois me mostrassem este lugar.
Муж давно домой не приходит,
вот мы и решили заглянуть в его кабинет.
