They'd never stop loving Serena: Blair, Lily, Eric, Nate, all her friends. But sometimes, even if they couldn't say it, they'd think it, and she'd know she was scaring them, and scaring herself. She lived in the dark. Not even Chuck liked Georgina, even though Georgina helped Serena be the kind of girl Chuck could respect. Old Serena was a blur, from morning to night, laughing and falling down, drinking herself silly and worse. And now that she realizes she's back there -- even if she's just a tourist, even if she's keeping her promises to herself -- she can't tell anybody she's even visiting that place. Not when her entire existence depends on the burlesque of New Serena. How do you make that phone call, home or to Blair or Nate, and say, "That thing I should never do? That road I promised I wouldn't ever walk down again? I'm standing in the middle of it." Can you imagine calling Blair and telling her you're drunk and scared and stuck in a bar, with two G's on the way?
If we don't have the people who love us to validate, to reify, the person we choose to be, it might as well not exist at all. New Serena exists by existing in the heads of everybody that loves her. She's forging a new reputation with her own two hands, and this is already a crack in it. Need a White Knight? Call Dan Humphrey. But White Knights don't come into the dark. If they see you there, maybe they leave you there. And then who will she be? Without Dan to prove that she's a good girl, she'll get stuck. She can already smell it on herself. So you don't call the White Knight because you don't want him to see you've fallen even this far, or to ask how it happened, or to see the other girls you can be. You don't call the White Queen, because she'd move earth for you, but needs New Serena as much as you do; she'd take one look at you, with Georgina all over your skin, and see herself on the floor of the bathroom again. Serena's redemption is redemption for everybody, and she's always covered everybody else's ass: when she was crazy, she was the crazy one, and now that she's sane, she's the light they warm themselves by. That's a lot of pressure. But it's not Blair that replaced Georgina Sparks in Serena's life: it's Dan. And if G keeps asking about him, she'll figure that out, and then he'll be toast. So she has to draw a line in it, now, and say this is a world that she has to negotiate all on her lonesome, without any backup except the dirtiest of friends; the one person she knows that won't judge her, not even silently. The one person who knows about Georgina, and all the girls Serena can be.
