Didn't Think This Through: When Adrien finds out that Chloe told her parents that XY is the father of her baby, Adrien goes through the logistics of what would happen if she continued to let her parents think this.
Adrien: If they're only accepting this situation because they think your baby's father is someone famous, they're going to want you to make that information public once it gets out that you're pregnant. And then XY will find out. And I'm pretty sure he and his manager will have something to say about it. Chloe: That... that won't happen. Adrien: People get sued for slander, Chloe. Chloe: It... it's not... Adrien: Mitigating circumstances aside, it probably wouldn't be good for his image, even if it were true. Lying about people in a way that negatively affects them is definitely something people get sued over. You need to tell your parents the truth before this gets out of control.
