Rosa gives Max some of her pea soup and stands beside him with a look of triumph. Liesel believes that this look has less to do with saving another human being's life and more to do with pride in her soup, which Liesel and Hans often scoff about. Max then vomits in the sink, saying that his stomach must not have been ready for food.
This chapter provides a lighthearted moment during a very serious situation. It also gives another glimpse into Rosa's character and at the caring nature that she often tries to hide behind her gruff exterior.
