I am me, and you are you. We're Chuck and Blair. Blair and Chuck. The worst thing you've ever done, the darkest thought you've ever had... I will stand by you, through anything. Because I love you. You are Blair Waldorf. This matters.
Of course they're all simultaneously freaking out about the future and trying to figure out who they are before anybody figures out they've been faking it this whole time. That starts at graduation and never, ever ends. I really do like this. I mean, Vanessa's overreacting because we've seen plenty of relationships work no worse or better, even through these responsibilities, than anybody else. Anne loves the Captain still, and Rufus and Lily are so busy creating their own drama that they haven't even noticed that nobody really cares what they do or how it looks, and Serena's never given a single thought to that crap, so the question for Vanessa is whether she's even really going to be with Nate forever -- which as a teenager she can't help but assume -- because if she is, that's a whole other bridge to cross, but it all depends on Nate being who he turns out to be, and she's the one saying there are options available to him that he just shouldn't explore, which is gross.
And I mean, they're all in the same boat, no matter what school they go to or don't go to. Jenny managed to weather this entire crisis including actual homelessness without anybody really noticing, beyond Rufus making it all about him. But I will say that this show takes it lumps for being snarky and mean and all, but at heart they're all pretty loving people, who really just want everything to be cool. Even Blair won't mess with your shit if you don't make trouble, and she's needier than everybody else put together. It takes a cruelty not one of these characters possesses to truly leave someone behind, which means if you get left, you're the only one to blame.
Jenny plays kind best friend to Vanessa about her breakup with Nate, which may or may not even happened. "I don't know," V admits, "I just left. It was bad, whatever it was." That's so real, I love it. "It was a bloodbath, but I don't know if it means anything" is, again, an apt description of every day of high school and most of the rest of your life, especially on this show. Dan welcomes Vanessa cutely to "the world of Upper East Side grandparents," reminding her he's gone up against them himself, and even though he eventually charmed Cecile's socks off, those rich old folks are a lot tougher than they look.
