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.
but I don't think we can go 
back to the house or to school.
لكن لا أظنّ بإمكاني العودة
للمنزل أو البيت
Aber bis zum Schluss kann ich wohl
nicht mehr nach Hause oder in die Schule.
Pero hasta que esto termine, no podré
volver a mi casa ni a la escuela.
Pero hasta que esto termine, no podré
volver a casa ni al instituto.
Mais je peux retourner
ni à la maison ni à l’école
Però non posso tornare né a casa né a scuola,
Mas não podemos voltar pra casa ou pra escola.
Правда, пока всё не закончится,
дом и школа для меня закрыты.
