How does Mr. Loomis treat Ann?

In Chapters 13-16, as Mr. Loomis recovers from his illness, he immediately begins bossing Ann around. Ann is a good person, therefore she attempts to excuse Mr. Loomis' behavior. However, Mr. Loomis becomes not only demanding, but physically bullying. This reminds Ann of what she knows of Mr. Loomis' crime against Edward and she quickly becomes frightened. The reader, too, is worried for Ann. Mr. Loomis is only looking to the future, to creating food for them that will last beyond the shelf life of the canned food they have been living off of. However, his bossiness seems to imply that he feels he is in charge despite the fact the valley was Ann's first. This suggests a conflict that might become dangerous for one or both of them.
