In the book Uncle Tom's Cabin Ophelia overhears the conversation between Topsy and Eva. What does she learn?

Topsy understands that Miss Ophelia can hardly stand to touch her, let alone love her. As her reply, Eva touches Topsy and tells her she loves her. She asks Topsy to be good for her sake. "A ray of heavenly love" descends upon Topsy with Eva's touch and words of love. Topsy begins to weep and promises she will try to "be good."

After this touching scene, Miss Ophelia realizes that she has harbored a hidden prejudice against blacks. She never knew before why she didn't want to touch Topsy, but now she admits to Mr. St. Clare that she realizes she felt racially superior.
