What does Jasmin remember about the recirculation unit breaking?

Jasmin remembers that Hannah realized that the recirculation unit was broken. By eight o'clock, Jasmin's captor had not come and everyone was getting woozy from the lack of fresh air. Jasmin got the children ready for bed. Then she had them lay down with her in the big bed. Jonathan was struggling to breathe. Hannah whispered that they would definitely wake up in the morning. She said they would not die that quickly. Hannah and Jasmin said they loved one another and then said goodnight.
