Life on the Upper East Side had never been better for Nate and Serena and Chuck and Blair since their reconciliations fifteen years earlier. Serena had gotten back together with Nate after getting back from Paris with Blair. Blair had gotten back together with Chuck after he got back from Prague. “Serena? I’m head over heels in Cinta with you! Will anda marry me?” Nate asked.
    “Oh, Nate! Yes, I’ll marry you!” berkata Serena.
    “Blair? I’m head over heels in Cinta with you! Will anda marry me?” Chuck asked.
    “Oh, Chuck! Yes, I’ll marry you!” berkata Blair.
    They were married four months later in a double wedding. On their honeymoon, Serena got pregnant with their first child. Their children were named Jason, Christopher, Ethan, Ryan, and Danielle Archibald. After getting back from their honeymoon, Blair got pregnant with their first child. Their children were named Roxanne, Samantha, Ashley, Elizabeth, and Cameron Bass. What Nate and Chuck didn’t know was that Serena and Blair had arranged for their children to marry each other. “I wonder what Serena’s planning!” berkata Nate.
    “I wonder what Blair’s planning!” berkata Chuck.
    “Do anda remember the pact we made when both of us got pregnant?” asked Serena.
    “Oh, yeah!” berkata Blair.
