The conversation builds tension and establishes conflict.
Explanation:
The conversation between Framton and Vera contributes to the story by building tension and establishing the conflict. In this conversation, Vera hints at the fact that a great tragedy had occurred, and that her aunt has lost her sanity. This makes Framton fearful and nervous. The reader similarly becomes more tense as he anticipates the way the aunt is going to react. The story also establishes conflict by introducing a problem that will only be resolved when we approach the climax.
