Z for Zachariah Chapter 12

I think Ann should try and change out Mr.Loomis routine. For example maybe surprise him with a nice new dinner or desert when he wakes up. There is alot of questions I want answered, like is there anyone else who survived the radiation? If so, how and where. But the book keeps talking about Mr.Loomis being sick. I hope in the upcomming chapters it gets more interesting.
