Serena sits down. This is her choice, coming down the pike. Since the story itself doesn't allow both, she has to weigh this morning's calamitous disaster with Dan against the fairly enjoyable relationship with Aaron before she speaks again. She can't know how manipulative Rufus has been, which should inform this choice, so it seems clearer than it should be: "Well, this may sound strange coming from me, but... If you want to be with him, then you should. Maybe it's your time now. After all that you've been through, you should at least try." Lily asks about Dan, and Serena gives a fatalistic hum. "I'm gonna try to make things work with Aaron. We're going to Buenos Aires for the holidays. That is, if it's okay with my Mom?" Lily agrees; she'd agree to anything. She throws her arms around her daughter; the tears in her eyes are tears of joy.
Jenny's steaming the wedding jacket when Dan arrives, complaining in a bizarre accent from some imaginary Scottish antipode of Argentina that she's off on holiday with Aaron. "Uh well she hasn't actually decided yet but he invited her and she's not sure so I think I tipped her in the direction of saying yes." Jenny asks why the eff he did, and Dan's like, "Because she asked me not to?" He realizes how boneheaded he just was, but says it's in fact not because he's a moron who had no idea what was going on, but because he's above "stupid games." Um, stupid games like, "Please ask me to go back out with you so I can go back out with you and we can have some sex?" That's real esoteric.
"If you play the game, then Aaron ends up dancing the tango alone and Serena would be with you," Jenny explains, and then garners one of the best lines of the episode: "You still have feelings for her. Right? Okay, so do you think you could put them into words? And speak to her out loud?" I was so hoping he'd be like, "That's just a stupid game!" But instead he nods delightfully, like a bobblehead of himself, and he's like, "YES. Or uh oh if she flies away first!" Jenny points out that there's an entire interfaith wedding still coming in this episode, because it's Gossip Girl and there might well be an earthquake and the Kennedy/Nixon election and half-human half-cat hybrids still coming in this episode, so he's got a couple minutes to play with.
