Okay, so Rufus and Lily's lovechild is writing a fan letter to Dan? And now adoptive parents are freaking out. I still don't get why the adoptive parents are so worried about 'losing their son'. So Lily gives the kid up for adoption, probably takes a couple of months for her to recover from the pregnancy. A few months after she gave up the baby, she meets Mr van der Woodsen. They're together for a few months, get married and 9 months later, she has Serena. Serena is 18, so Baby Humphrey would have to be at least 20-years-old. Why are the adoptive parents so worried that Lily and Rufus are going to take this kid away from them? The kid is already legal, it's not like Lily and Rufus can claim parental guardianship over him. All the lying and fabricating that he died, and deleting Dan's number from his phone all seems pretty pointless to me.
