Serena: So, how's your mom doing? With the divorce and everything.
Blair: Great. So, my dad left her for another man. She lost fifteen pounds, got an eye lift. It's been good for her.
Serena: I'm really sorry.
Blair: Yeah, I could tell, since you didn't call or write the entire time it was happening.
Serena: I, I know, it's just… boarding school --
Blair: I don't even know why you went to boarding school to begin with. Do you know how it felt calling your house when you didn't show up at school and having your mom say "Serena didn't tell you? That she moved to Connecticut? "
Serena: I just… I had to go, I… needed to get away from everything. Please, just trust me.
Blair: How can I trust you when I feel like I don't even know you?
Serena: Well, let's fix that. I saw you at school with Kati and Is and I get it. I don't wanna take any of that away from you.
Blair: Because it's just yours to take if you want it.
Serena: No, that's not what I mean. I miss you. I just want things to go back to the way they used to be. You know, walking to school together, dancing on tables at Bungalow, night swimming at your mom's country house? You're like my sister. Y'know, with our families… we need each other.

Blair: Well, you missed some classic Eleanor Waldorf meltdowns. If it wasn't such a tragedy it would've been funny. Actually, it kinda was.
Serena: Well, I wish I could have been there.
Blair: You are now. Well, I have to go meet Nate. We kind of have something special planned.
Serena: Well, I don't want to keep you, but, um… I love you, B.
Blair: I love you too, S.
