Lily: "Thanks for fucking my sister over with me, Ivy. Here is a million-dollar check I just wrote with a ballpoint pen that says One Million Dollars on it."
Ivy: "Lily, for real though. I came here because I was being paid, but fell in love with you and your family the second I got here."
Lily: "You keep saying that, but I have formed an opinion. Not to mention the fact that there's actually nothing to be done about it. You're a loose end. I already have three kids I pretend don't exist, I can't have another one bouncing around. Not when I'm so close to provoking Rufus's suicide."
Ivy: "I could tear up this check?"

I gotta say, this scene got to me the most out of the whole episode, even more than finally getting Blair back, because it's so well-acted and you can see all sides of them both. You see Ivy thinking, "This time she'll believe me and it'll work and I can be okay again," and you see Lily thinking, "There just isn't a way to do that." She takes Ivy's hands, not roughly, and smiles.

"Goodbye, Ivy."

It's the coldest room in the universe. Maybe I'm just doing my own issues, but there is something very real here, I think. Something about aspiration, sure, and moms, but also something about broken people trying to fit together, or this hope that somehow the person with all the power will see that you're being real, or good, or valiant, or whatever, and they just look you in the eye and smile and say, not entirely without regret, "Goodbye." It's a breakup, it's that WASP hardness, it's getting evicted or expelled or fired. A sudden absence, right there in front of you. It's awful. It's so much worse than Lily simply screwing her over again.

As Ivy's tearing up the check in the elevator, Lily answers the phone.

Wm vdW: "I got Carol's half for you, like you asked. But are you sure you're going to take care of Lola with it?"
Lily: "Why would I punish that little girl just because of your extramarital affair?"
Wm vdW: "You've done worse for less reason. In the last twenty-four hours."
Lily: "I'm not a monster, William."
Wm vdW: "Good thing you're so trustworthy, huh?"

Wm vdW: "Take me to JFK, actually. I'll figure this one out on my own."

Lola: "Hey, sis!"
Serena: "Fuck you want? Get out."
Lola: "I thought we could bond over destroying our parents together? You get back at Lily, I get Carol out of jail..."
Serena: "Uh, not interested in being your sister right now, thanks to daddy issues. Please just stay away from my family from now on."
Lola: "Sure, right after I steal the Gossip Girl website from you."
