Jokes about Pedophila with Aunt Debra and Seth are in the first/second act, but it’s brushed off for comical reasons, and Kim, Seth are clearly uncomfortable by Aunt Debra’s advances and tell her to stop.
Kim is verbally abused by her condition, students shoot her weird looks in one of the songs, and Kim’s dad says in act 2, that he wishes she wasn’t born, so they could have a “normal baby” . Kim’s mother says this in private to her father as well, that this baby shouldn’t have the condition.
Seth is Sexualized by Kim’s father and aunt, by thinking that “he wants to get in Kimberly’s pants” in the car scene in Act 2 and the pedophila joke from Aunt Debra early on. He is shown clearly uncomfortable but is played off for comical reasons.
Kimberly ages 4 years older because of her condition, so she looks like an adult women but is mentally 16, and Seth is shown as a teenager/young adult.
I would say words like that aren’t displayed, but the parents of Kimberly talk about her like she could have been a “normal child”.
Kim reflects on this in Act 3, asking her mom and dad this, they say nothing. The students during the disease number in Act 2, look at her like she’s different when Kim does her project on her condition.
Kim’s mother and father do with Kim, and the difficulties of pregnancy, and that traits get passed down through another baby that her mom is excepting.
Kimberly is taken to a hospital, after she pretended or fainted in Act 2, and they show her in a hospital with a gown and grippy socks, a IV tube and heart monitor. She sings a song with Seth about when she could leave the hospital and go back to the real world.
Mentions of miscarriages or at least implied. Kim’s mother is having a second child, and while it isn’t shown, it’s mentioned throughout the play in the songs. “Hello Darling”
