"She really needs to tone down on the social niceties," Chuck says as he sits beside Serena. "It's embarrassing." S says he's eventually going to have to work out his issues with B, but from where he's sitting, he's issue-free. As is Serena, because the mysterious G, Georgina Sparks, is nowhere near the "fair isle," of Manhattan. "She's in Switzerland, dating the prince of Belfort." Serena's giddy about the near miss, and Chuck suggests it's an opportunity to enjoy the gifts of G with peace of mind ... "And maybe Chuck in the room?" She pushes his face away, giggling, and reminds him they're brother and sister now. He ruminates for a moment. "Georgie always brought out the devil in you. Part of me is a little disappointed she's not here." S is like, "Yeah, the dick part of you," but Chuck admits to missing Old Serena.

Which is key to this whole episode, because the further S slips this week, the more she depends on Chuck. And I don't think it's that they're suddenly friends, I think it's more about the fact that before she left, Chuck was a huge part of her life and possibly the only person that could keep up with her, and the reason we haven't seen them together much before now is that she had drama and he had drama, and she and Blair have A stories every week basically, so when would they spend time together? But also that coming back, she made a concerted effort to avoid that part of her life, which meant avoiding Chuck and the associations he evokes. Which is even more interesting if you think about the last fourteen episodes and the ways they have interacted, because that means he had all of the Blair issues with her disappearance, plus the fact that he was too dirty for her to deal with when she came back sparkly and new. So now Chuck's resentment of Dan, which looked originally like Mean Rich Guy high school shit, has this extra flavor of Dan being a symptom of Serena's rejection of Chuck.
