Maybe there's something even more important than love.
Ahh! There's people in my bedroom wall!!!
How dare my parents protect our enemies!
Korrina and her parents are talking about one of her teachers that went to the Gestapo because she refused to let the Nazis take her father without her. They tell Korrina that her teacher went for love and then all three of them enter a discussion about "what is more important than love?".
Korrina finds out that her parents have been hiding Jews behind her bedroom wall. At first she sees her parents as "the enemy" and writes about how they are traitors in her "black book".
Korrina starts to get along with the Krugmanns (Jews) and learns that just because they are Jewish, they are not traitors or monsters. When she is at her Jungmadel meeting, she was a little behind when the whole group had to say "Heil Hitler" and she got slapped by her Jungmadel Leader!
The Krugmanns (jews) had to leave because the Rehmes were under suspicion. The Rehmes had a very clever plan and hoped that the Krugmanns didn't get caught.
Nazis searched Korinna's house, one of the Nazis was Rita's brother, Hans. He had Korinna's black book, and there is only one person who could have taken it and given it to him and that was Rita, Korinna's best friend. (Extra note: Rita turned Korinna and her family in because she thought they were traitors, yet at the same time, we see the Nazis as the antagonists. It's interesting how frame of reference is an important factor in this situation...Who did the right thing?)
Korinna and her parents have to leave because it is too dangerous to stay, and they know that they will be executed if they stay and the Nazis find proof that Jews were being sheltered in their home. It was at that moment that Korinna realized that freedom is perhaps more important than love.
