Sounds like a good talk. I see two possible routes, considering your plot synopsis on the OP and those two lines:
1) (semi reasonable, perverted) Peter makes sweet, hot love to Eleanor, and she reacts horrifically to it, destroying Peter in the process, and forcing her to find someone to help her.
2) (likely) Peter tells her about someone who can help a person like her, since he knows his family's hospitality will run out soon. That man is Jack Wynand. Soon, Ellie gets sick with a strange disease, and she has to find him anyways, since he's the only doctor for 100+ miles.
