She is starting to think that young people just want to get rid of her. Once she sees the words "odd man out" written on their photos with Sergey and Masha. From that moment, she realizes that she starts to go crazy, especially since Sergei adds fuel to the fire of their cruel jokes about this situation. In desperation, Vera turns to a psychiatrist, but the treatment is interrupted with a car accident.
