Summary
Analysis
Liesel is awakened by Rosa's voice, and she expects her to launch into a tirade, but Liesel comes out and is shocked to see Rosa feeding Max her pea soup. She looks serious, but is pleased that he is enjoying her food. Max vomits from eating too much and Rosa cleans it up. They all sit down and Liesel watches from the hallway, wondering at her foster parents.
Rosa surprises Liesel (and the reader) again by accepting Max fully into the home, feeding him and never questioning whether he is welcome or not. Liesel realizes these are special people – the minority in such a time.
