Adam's claustrophobia increases, which is illustrated in a reference to Arthur, and the fire escape cage where he lives. Adam knows what it is like to feel trapped, so it makes sense that Adam expresses empathy for Arthur and his cage. Adding to the suspense of the novel are the odd circumstances surrounding—his open white shirt and the way the other man orders him around.
We learn that Anthony's old hat and his army jacket are among the few items Louise saved from before they left their previous life. We understand why Adam is so attached to these items and why he immediately revealed that these were the items he took for his journey to Rutterburg. The presence of these items also makes us curious about the contents of his package and whether it is something that Louise saved.
