Georgina lights up with devil power when the wedding march begins and nobody appears. Serena steps forward immediately, of course, and addresses the crowd. As she's telling them it's going to be okay, Georgina prances past. One eye on her, Serena promises to check on things, and follows; behind her is Blair, who reaches back for Chuck, without looking: for the hand she knows is there.

"I can't believe you. You want to know what our future looks like, Lily? It looks like this. We are going to fight. We're gonna want to kill each other sometimes. That's what marriage is about: Not running away from every little problem. Sticking it out, you know? Committing. Do you think you can do that or not?" Scott appears, listening carefully to the silence, until Lily shakes her head. It's too real. "I don't think I can."

"...In order correctly to understand a plant nothing is more necessary than to remember that its characteristics are the result, not of its inheritance alone, nor of its environment only, but of the interaction between the two."

"Wait, so you're not getting married?" Scott's alarmed; Rufus is shocked to see him, but Lily snaps on his ass. "What? Who are you? This is a private conversation at a private event. How dare you?"? Scott, feeling dumb, squished down into nothing with that Rhodes woman charm, brushes past. Lily's grossed out, asking if Rufus knew the kid. Before Rufus can reply, Georgina appears, surrounded by the entire cast looking murderously scared: "--Your love child. Yeah, not dead. Congratulations, it's a boy!"

That's my fever girl. "Man is born to trouble, as the sparks fly up." Or, as our guide Dr. Gager already told us:

"Mutation ... offers a method by which evolutionary changes may take place within a much shorter time-period than was demanded by the natural selection of fluctuations."

Lily almost barfs, of course, and Serena immediately reminds everybody that Georgina is a huge liar, which is technically true except when it counts. Jenny, hilariously, is like, "What is she even doing here?" Lily and Rufus confirm for each other that their son died, and Lily starts yelling at him about hiding a relationship with their dead son's brother, but Dan finally speaks up. "I'm so sorry, I was going to tell you after the wedding. I found out just yesterday." The misery, the terror, the shame: the absolute, stark, heartbreaking hope on their faces. Man.
