During their walk in the park, James is brooding and angry; Sibyl dreams of "Prince Charming" and fantasizes aloud, in a somewhat childlike manner, about the great success that her brother is to be.
James hates the "young dandy" who is courting his sister, hates him the more because he is a "gentleman." He warns his sister that the man wants to enslave her and repeatedly threatens to kill the "gentleman" if he does Sibyl any wrong. James is especially angry when Dorian suddenly passes through the park in an open carriage, but only Sibyl actually sees him. James is also angry with his mother. At the theatre one night, months before, he had heard "a whispered sneer" about her.
After James and Sibyl return from their walk, he confronts his mother. He wants to know if she and his father were actually married.
The crude situation reminds the melodramatic Mrs. Vane of a bad rehearsal. She simply says, "No." James accuses the father of being a scoundrel. Mrs. Vane defends the man, now dead. She knew that he was "not free" when she got involved with him. He would have taken care of her and the children had he lived. He was, after all, a "gentleman." James insists that Sibyl never be told about the father and notes that his sister's suitor is another "gentleman." He repeats that he will track down Sibyl's "gentleman" caller and "kill him like a dog" if he wrongs the girl, a threat that becomes very important later in the book.
