In Chapter 16, Uncle Henrik rewards Annemarie's exceptional courage and maturity. Although he was reluctant at first to tell her about the Rosens’ escape, Annemarie shows through her actions that she is brave and responsible enough to keep the secret. In a situation where many lives are at stake, Annemarie must earn the trust of the adults before they can confidently share their plans with her.
Annemarie demonstrates her maturity throughout the chapter, even in less urgent situations. When she returns to Uncle Henrik's home after delivering the packet, she realizes that Blossom needs to be milked, and because there is no adult in the house, she does it herself. She also cheers Kirsti up, who is upset because Ellen left without making a dress for her doll. Annemarie knows that Kirsti is behaving selfishly only because she does not know the reason for the Rosens’ midnight escape. Even if Annemarie is annoyed about Kirsti's childlike concerns, she does not scold her sister. Instead, she simply promises to make the dress in Ellen’s place.
