Call-Back: Back in Chapter 55, Tom warns Adrien that women in pregnancy can get rather... frisky due to the raging hormones. Here, all of the girls suffer from it.
Double Standard Rape: Female on Male: Played for Laughs. Everyone walks in on Alix viciously making out with Nathaniel. He stops her from going further because he knows that as soon as her hormones subside, she'll turn violent on him for "letting" her.
Adrien: Can one of you go in there and and splash some water on Alix or something? Maybe take her to the nurse? She kinda tried to molest Nathaniel, and now Nino's holding her back, and I'm worried for his safety.
Everyone Has Standards: When the guys agreed to help their pregnant-partners however they can, they didn't mean sexually. Kim didn't get the hint, much to the other guy's exasperation.
Hormone-Addled Teenager: Being deep in their pregnancies, the various girls in the class go through very turbulent hormones that make them rather Lustful. Alya gets handsy with Nino, everyone walks in on Nathan and Alix making out and Kim was caught having sex with Ondineby her dad.
Pun: Adrien thinks of a rabbit-joke based on how voracious Alix is acting.
The Reveal: Not only are Kim and Ondine having sex, but after her dad caught them doing it once, they both had gone through a Shotgun Wedding (on paper, anyway).
Simple-Minded Wisdom: Adrien finds Kim's reasoning for marrying Ondine (they love each other, they're having a baby, she's super happy, what's the problem?) oddly profound.
