Dan almost cries and looks away, and finally Serena's like, "So what, Dan? We're exactly where we were at the Bass's brunch when we first started dating? I'm not who you thought I was, and you can't forgive that." Dan's like, "I have only increased tenfold the backlog of things to hold against you. I tremble under the mighty weight of my resentments! It tastes like power and the sense of control only victims and sadsacks understand!" And she's like, "So that's it then? It's just... Have a good summer, I'll see you back at school?" He totally goes, "I guess." Then he agrees that yes, that is how gross he is. She stands up, amazed, and clomps off through the grass. And then a swarm of vipers as long as your arm floods up out of the New York City water table, cornering Dan on all sides, and all that's left when they're done is the white rubber ONE bracelet that Dan got from Richard Gere when they were having a Superiority-Off for charity. (It's like arm wrestling, only instead of your arms, you use how you're better than the other person. Gere won because he has a Prius, while Dan is still driving Vanessa's lesbian sister's gas-guzzling band van when he needs transportation. Good show, Gere.)
Chuck clinks his glass and begins. "My father is someone who goes after what he wants, and Lily van der Woodsen was no exception. In typical Bass man fashion, his pursuit was direct and at times, not exactly subtle..." Blair sits across the room, looking completely amazing, because when she's seated looking over her shoulder at you, you can barely see her dress.
Chuck is inspired by the new vision of loveliness unobscured by her excruciating dress, and puts down his notecards. "One thing I learned from my father's courtship of Lily is the importance of perseverance. That in the face of true love, you don't just give up, even if the object of your affection is begging you to..." The guests laugh, and Blair watches him intently. "And one thing I learned from Lily is the importance of forgiveness." Serena sits down, of course, right at this word, and an instantly worried Lily takes her hand as Death Cab starts to play under the toast. ("We're not the same, dear, as we used to be / The seasons have changed and so have we...") "She gave my father the gift of a second chance," he says, referring to the time he accidentally said Bart was having a fake affair, "And in kind, I've watched him become someone actually worthy of that gift. And one day..." He meets Blair's eyes, "I hope I'll be lucky enough to find someone who will do the same for me." Blair is moved. Serena feels like dirt. "To the happy couple!" ("There was little we could say and even less that we could do / To stop the ice from getting thinner, under me and you...") They toast; Blair smiles tenderly at him but she's already on the ice and doesn't even know it.
