Chuck: Did you notice her talking to anyone? Whoever she kissed seems to have had an effect. "Life-changing" were the words she used.
Dan: Well a life-changing kiss might not be something you want to mess with.
Chuck: What are you trying to say, Humphrey?
Dan: With you, she was always caught up in schemes and takedowns. But that's not really her. She's intelligent, she's intuitive. You know? She weeps when she watches Nights of Cabiria.
Chuck: How do you know that?
Dan: Uh... Serena told me. But listen, if Blair's happy, I mean maybe you should let her be.
Chuck: You care more about Blair's happiness than I knew.
Dan: Eh.
Chuck: Thank you for your time.
