S2E9: a character remarks that he can only imagine his girlfriend kissing someone else if she was crying (implying that she would have to be forced to do so). S3E19: a plot point is that a male teenager gets angry at his girlfriend for saying no to sex. He pushes her down on a bed and continues to kiss her, attempting to remove her belt despite her protests. In order to end this interaction, she has to physically push him away. Season 4 (in particular, S4E9, S4E10, S4E19, S4E20): features a relationship between an 18-year-old student and a professor in his 60s. This is handled with a comedic touch, but some viewers may find the imbalance of power between the two (due to the professor's position and age) unsettling.
