Dan chases Serena down on the street and immediately apologizes, because he knows he was out of line. "Yeah, you were. Look, I'm sorry that Blair and Chuck messed with Vanessa. She doesn't deserve that." Like fuck she doesn't. "But instead of hurting Blair, you should have been honest with me." Dan knows, but calls back to Amanda Lasher, and how he was so terrified of fighting with Serena, about anything, and it getting nasty, that he didn't know what to do. He gives her some dumb speech about how they should be friends, and how they should be honest with each other and he totally gets it, and she's like... "Okay, I like this guy Aaron." And they totally forget about the Blair thing altogether, awesomely, and start talking about themselves some more. So real.

Dan gives her his blessing or whatever, in a way that isn't disgusting, and as she's trying to explain her vague attraction to Aaron she realizes she's actually known him her whole life. "Oh my God. 'Cecil The Caterpillar'! Camp Suisse!" Dan's like, "Are you having a seizure?" She explains that she is not a crazy person who speaks in riddles, but in fact a person who went to summer camp with Aaron Rose, and he didn't tell her. "Oh, wow. You... You went to camp in Europe together. Uh, that's cute." And Dan has accumulated so much goodwill this week that it's actually kind of a sympathetic little ouchie. "No, it was much more than just camp. We got married! Uh, there was a small ceremony with licorice rings on the banks of Lake Geneva. It was tasteful..." I mean, her whole life was just wedding after wedding, so that's probably the only game she could think of. "I took a bite out of my ring, so he asked for a divorce... But we were happy for a time." Serena van der Woodsen rules. Suddenly she's like, "Fuck! Forget you like we just forgot Blair, I gotta go tell him I figured out the riddle! Do you mind?" He actually doesn't, because he's cool now: "Look, he's the ex-husband. I'm just the ex-boyfriend."

Serena makes that kissy face, almost hugs him, does the nod that she always does where she can't quite figure out if the conversation is over, and then runs off, only to spot Aaron getting on his motorcycle with some other girl. Her face falls. "The problem with fairy tales is that they set a girl up for disappointment. In real life, the prince goes off with the wrong princess..."
