Not sure it is really an irrelevant point, as it’s engendered so much discussion. I would respectfully disagree there are cultural power differentials that make it acceptable, say, for a 25 year old female teacher to sleep with an 18 year old senior, but unacceptable if the genders are flipped. Camille may not be in a position of authority over John, but she’s old enough that I find her thing with John to be squiffy, regardless of their genders. Mileage certainly may vary, of course. I see the John thing as just one more in a long line of bad decisions Camille has made since returning home, fueled by vodka, triggers, memories, and Mommy Dearest.
