Wilde uses this chapter to continue his character development of both Basil and Dorian. Basil shows himself to be a decent, caring human being who is as concerned for Sibyl and her mother as he is for Dorian. Unlike Lord Henry, he does not encourage Dorian to turn away from the girl's death or treat it like some entertaining fantasy. In a moment of heightened irony, Dorian accuses Basil of being "too much afraid of life." In fact, Dorian is afraid that Basil will see the portrait and thus learn of his secret pact.
As for Dorian, he shows himself to be fully immersed in his new life of selfishness and manipulation. For example, when Dorian learns of Basil's strange admiration for him, an admiration that has obviously had a major impact on Basil, Dorian is simply pleased to be adored by Basil. As he wonders if he will ever feel that way toward someone, it becomes evident that he already does — while he respects Lord Henry, Dorian only adores himself. When he gets Basil to admit his secret without having to reveal his own, he feels pleasure at having manipulated the situation so completely to his own advantage. His decision at the end of the chapter to hide the painting reveals his commitment to a life of vanity and self-gratification.
