Scene 3 starts out with everyone anticipating Mr. Franks signal that everything is fine and that they can break the silence. They don't want to be found, of course. When everything is clear, everyone is relieved. Anne takes Peter's shoes and he chases after her, and ends up getting angry. Peter goes to his room and Anne leaves him alone. Anne talks about how after all day, she just want to move around and dance, and that "there's something wrong with that boy [Peter]." Anne's father dances with her.
Peter feels ashamed when his mother is teasing him about his "little girl-friend" (Anne). The conversation is shifted when Mr. Frank comments how Miep is running a little late. Then, everyone hears a car outside screech. Everyone stops what they're doing to listen. But they hear it driving away, and everyone is relieved. Anne comes out of Peter's room after feeding his cat, and is wearing his clothes. Everyone is amused seeing her, and seeing Peter so angry. Peter calls her Mrs. Quack Quack, trying to distract the others with this. Anne and Peter continue to pester for a while.
Mrs. Frank thinks that Anne has a fever, but decides she's all right. Mr. Van Daan come into the room. They discuss their school work. After Anne asks Mrs. Van Daan if she can try on her coat, they start talking about boys and Mr. Van Daan seems like he's heard all about these stories too many times. Anne and Mr. Van Daan get into a little argument when he's looking for his pipe. Anne accidentally spills milk on Mrs. Van Daan's special coat. Mrs. Van Daan is absolutely furious. The Franks have a conversation about how Anne should be more like her sister, Margot, who is always kind to the guests. Anne is angry with this idea.
Miep finally arrives and everyone gives her their list of things they need. Mr. Kraler arrives as well, which is a surprise to everyone. His visit is rare, but he is a very likable person. He come with some news, that another Jew, a dentist, is in trouble, and needs somewhere to hide. He asks them if he could stay with them. Â They discuss where the new guest would sleep for the few days he is there. Dussel, the new guest, meets everyone. Mr. Kraler says that he helps them because he doesn't like the Nazis telling the Dutch what to with Jews. Anne tells Dussel that they are sharing a room since space is tight.
While Anne and Dussel are going to sleep, they talk a bit, and Dussel tells her that he will have to get used to having a room mate since he has no one. Anne tells him the protocols and schedule. Dussel tells her he gets along with children well, so she won't have to worry. They talk and get to know each other a little bit, and get along just fine.
The scene ends.
