Her cover story is that she doesn't feel like it, and will be going to the spa for a facial instead. Sometimes you go with what feels right.
Bart: "Hey, do you want me to go yell at Chuck at all? Since I know you're with him."
Lily: "No, I'm over the fact that Gossip Girl reported that I acted like a huge whore with the grossest person in New York. I'm all, Whatever! And it wasn't him anyway, he told me so. And before you ask unnecessarily, yes I believe him."
Nobody: "You know what, now that I think about it, it's probably the insane con artist with a huge grudge against Lily that is now sleeping with Rufus and has access to all his shit."
Lily tries to drag Chuck off for a mother/daughter exploration of the grounds and endless recitation of her ridiculous childhood that has never made sense in terms of either time or space, but Blair jumps in with a quick Princess Anne horse joke that never lands and in the end doesn't work anyway, so Lily runs off with old Chuck.
Sage: "Nate, you remember my dad. He punched you for fucking an underage girl?"
Serena: "Yes, and then I talked such bullshit that everybody got over it."
Steven: "You want to be best friends now?"
Nate: "Yes, let's be best friends. Oh, we can talk about doing it with Serena! That's how this show usually operates."
Announcer: "Sheikh Hassan's daughter is just leaving the field. Avoid the steaming divot!"
Chuck: "Lily, I have to go talk to that little girl for a second."
Lily: "Nothing odd about that, no sir."
Chuck: "Can I buy your horse? Just kidding, I gotta yell at you about your dad for a minute."
Georgina: "Pick your ho, Humphrey. I don't have all day."
Dan: "This just isn't me! I respect women, just as long as they do exactly what I say at all times!"
Georgina: "Give me a goddamn break."
Weird because I think there's an actual, intentional comparison here between Dan literally shopping for poon and Chuck discussing the buying of horses with various people. That sounds like too much credit, though.
Chuck: "[Random Bruce Wayne talk.]"
Iman: "That's so funny you would say all those words, because Lady Alexander was my childhood horse and Bart bought her from me instead of sending her to the glue factory and then randomly had a painting painted of her and then also bought a million other horses from my father, a Sheik."
