Lev has essentially described what likely happened to his father after the publication of his book, and indicates that it was probably Gerasimov who is responsible for his father's arrest. Kolya’s recognition of Lev’s father’s name indicates that his father really was a famous, or at least good and moderately well-known poet. The exchange about Lev’s father again brings up the contrast between a kind of romanticism and realism. Now, though, it is Kolya who is being romantic, as he focuses on the excitement of having a famous poet for a father, but Lev is focused on the reality of his lost father, and so such romanticism merely makes him angry.
