This is the first appearance of Susan Misner (Alison Humphrey).

Gossip Girl: Whoever thought monarchy was dead didn't realize it just changed zip codes. So, what will it be, Nate? Blair Waldorf's hand or your father's head?

Serena: Make a wish, Blair.
Blair: It already didn't come true.

Gossip Girl: Happy birthday to who? Forget cake and ice cream, I'm saving room for just desserts. Looks like Chuck's wish might come true.

Gossip Girl: Speak of the devil and he doth appear -- wearing his trademark scarf. Careful, B, hell hath no fury like a Chuck Bass scorned.

Serena: So you brought Vanessa as your date to Blair's party?
Dan: No. No, you're my date. I just thought it might be a good opportunity for all three of us to hang out.
Serena: Oh yeah, because it was so fun and not remotely awkward at breakfast this morning.

Chuck: Nathaniel!
Nate: Where's the girl?
Chuck: In my dreams. I was trying to get some shut eye. What's on your mind?
Nate: Just my mom.
Chuck: Sounds Freudian.

Chuck: So, where is your head?
Nate: Spinning. I mean, my mom wants me to get back together with Blair so Eleanor doesn't pull out of the business deal. It's all because of my dad's whole trial thing, you know?
Chuck: I'm sorry about that. But look, if you're done with Blair, be done. Don't cave to your parents' wishes if they're not your desires.

Chuck: 12:01. I'm sorry.
Blair: No, you're smarmy. There's a difference. If you're coming to collect, you can forget it.
Chuck: Turn around.
Blair: You get grosser by the second.

Anne: May I remind you that it was your own rash actions that got us into this predicament.
Nate: We're in this predicament because dad has a drug problem. I was trying to help him.
Anne: Then help him.

Alison: Hey, can we talk?
Dan: Well, that depends. Are you back for good?
Alison: I don't really know. Your father and I haven't really had a chance to talk, so ...
Dan: Well, do you want to come back?

When Jenny comes home after spending time with Nate, she has a blue shirt on. However, when she was with him, the shirt she was wearing was red, not blue.
