What does Chillingworth most likely see when he secretly enters the minister’s room? What effect does the incident have on the physician?

The end of the chapter brings to light some of what previous foreshadowing promised. Earlier, Chillingworth told Hester that he would be able to know her partner by reading his heart. In the final scene, he opens the minister’s shirt, to look at his chest. The minister was Pearl's father. Hawthorne, however, indicates that Chillingworth is surprised by what he discovers, implying that Chillingworth never fully suspected Dimmesdale of being Pearl's father."
