Answer:
The reverend learns that Turner went to the island with Lizzie Griffin, an African American girl.
Explanation:
Turner falls in love with Lizzie, a black girl. Turner grew up in a racist community and always heard that blacks were dirty, inferior and unworthy, but Lizzie seemed totally different from that, which deeply caught his attention. Lizzie invited Turner to Malaga Island, to meet her family. He goes and is delighted not only with the environment, but with the people as well, who treat him very well making him spend a very comfortable day.
However when Turner returns home he has an unpleasant surprise, he discovers that the inhabitants of the city of Phippsburg are determined to expel all blacks from the island to build a resort that will bring profits to the city. Turner does not approve and is forced to admit that he spent the day with a black girl, when he admits, he receives another disappointment, as Reverend Buckminister is forced to side with the people of Phippsburg.
