Myshkin follows Nastasya and Rogozhin, and after the three live for a time in Moscow (where Nastasya decides to marry Rogozhin, then refuses, and comes to Myshkin for comfort), Myshkin returns to Petersburg. He visits Lebedyev and also visits Rogozhin. He tries to convince Rogozhin that the two men are not rivals for Nastasya and, seemingly, Rogozhin understands and swears to be Myshkin's spiritual brother. But after Myshkin leaves Rogoshin, he wanders absently and finds himself at Nastasya Filippovna's house. The girl is not at home but Myshkin senses that Rogozhin has followed him. He is correct; Rogozhin has followed Myshkin to see if he would go to Nastsya as the victorious suitor. Rogozhin then follows Myshkin bcak to his hotel and attempts to murder the prince but Myshkin suffers an epileptic attack when he realizes that it is Rogozhin who is hiding in the dark with a raised knife. The attack saves the prince's life.

Recuperating at Lebedyev's villa in Pavlovsk, Myshkin is visited by the Epanchins and, during their visit, several young men demand to see the prince. Before the Epanchins, the young men demand money from Myshkin; he is not the true son of Pavlishtchev, while Burdovsky (one of the intruders) is, althought illegitimate, and they demand that Myshkin give Burdovsky his rightful inheritance.

Myshkin exposes the young men as frauds; he has known of Burdovsky's claim and has had Ganya verifying the facts of the case. Myshkin says that he will not give the men conscience money, but, he says, because Pavlishtchev did take an interest in Burdovsky (the boy is the nephew of a woman Pavlishtchev was once in love with), he offers to give Burdovsky 10,000 rubles - approximately what Pavlishtchev spent on Myshkin's education and medical bills. Madame Epanchin is aghast at such unnecessary extravagance and , after Ippolit, one of the young men, damns the company, she gathers up her family and leaves.

As they leave, a carriage drives up and a voice shouts to Radomsky, an admirer of Aglaya Epanchin, about some IOUs; Myshkin recognizes the voice as Nastasya Filippovna's.
