Basil's reason in order that dorian of was showing the painting

Basil asks Dorian to return to pose for him but he refuses, then he asked him to teach his portrait to him and, when Dorian refused, seemed to him to be strange and said to him that it wanted to expose it. On having heard this, Dorian became nervous and said to him that it could not expose it for a few motives that it could not say to him, then they did an agreement, if Basil was saying to Dorian because estan importantly for him, Dorian would teach the portrait to him. Basil, though it cost him, spoke to him about his feelings towards him, and on having ended, Dorian said to him that it was disappointing and did not want to teach the portrait to him.
