The twins are fighting. It is obvious to others that the reason for the disagreement is Plato. Tatiana Vladimirovna is trying to resolve the conflict, but it only makes it worse. Now all the girls are offended by the psychologist. Broom feels like he's living in a fairy tale about a stepmother and stepdaughters, and he's already tired of it. Borya suggests a radical solution: take the whole family on a winter picnic. It remains to convince the daughters to go there.

Broom is counting on the inexorable power of the bureaucracy to disrupt Sonya's wedding. It is enough to destroy the act, and there will be no marriage. All that remains is to find this document. During the search, he discovers a pregnancy test, and now Vasiliev is sure that his eldest daughter is expecting a child. Meanwhile, Lisa promotes the idea of opening a living corner in the school. Taisiya Kirillovna promises to help, but only if the girl conducts lessons with the second graders.
