"It-Girl Happened One Night" featured the continuation of the battle for Bass Industries, as well as major developments on the Dair front, as our official review noted.

For further examination, we turn to one of favorite pieces of Gossip Girl media coverage, N.Y. Magazine's patented reality index. Behold, the weekly +/- scale:

• Wait, Gossip Girl spotted Raina and Chuck IN the Bass apartment? So she is Eric! Plus only 1, because this could also be a minus. Or it could be Vanya.
• Without reading it (or maybe after reading it, it’s unclear), Blair analyzes that Dan’s article is about "a boy from Brooklyn and an untouchable Upper East Side blonde," and that supporting it "would be like showing up at an accessories shoot in Crocs." Plus 10.
• Plus 2 for Damian knowing that lurking in a dark alley wearing leather gloves is enough to scare Eric into thinking he actually has something on him.

• Serena and Ben are sitting out Valentine's Day because it's "too much pressure." After her mother had him falsely imprisoned for three three years, Valentine’s Day is too much pressure? Eh, Minus only 2.
• Chuck offers to prove the cache of the Bass name in … one night? Come on. He’s a trickster, but he’s not a moron. And neither is Lily. (The only person who proves their non-moronity in agreeing to this is Russell, natch.) Minus 10.
• Blair submits Dan’s article to Vanity Fair instead of Details? Maybe this is another devious plan for him to fail, but … it doesn’t seem like it, so Minus 3.
• Rufus and Lily’s V-Day plans involved Jacques Torres fondue and Love Actually. Everyone knows that’s a Christmas movie, but Minus only 1 because that’s clearly the influence of the perpetually sweater-clad Rufus.
