Can someone explain what happened in ch-5 please? Edit . Sorry I meant ch 15

well daath is setteling in in his knew live. He's searching for his sister. And honoring his agreement with juda (paid sex). But he doesn't want to get pregnant yet so he's still taking birthcontrol pills. Juda isn't happy that daath is constantly wandering outside. Eventually Daath gets into a fight with other omegas at the residence. Finally they end up in Juda's second house (probably in the hope of cooling the situation down?)
