Not necessarily. During my durge run she told my character they'd go skinny dipping once everyone was asleep. Emperor cock blocked my guy though. Never happened.

I had skipped the grove and somehow got enough rep with her to proc that interaction. If you miss the skinny dipping thing though, not possible. Withers is a good way to figure out if you done goofed. He'll tell whomever character approaches him that they got no removed when you have no active romance options, and that they should care for them if they do.
