Blair: Because I need to do a story on Raina for the magazine tomorrow night.
Serena: Okay, well why don't you just ask her yourself. After the Chuck thing doesn't she owe you a favor?
Blair: Yes, but she's not answering her phone and I can't leave the office. Besides it's better this way. Just two It Girls talking. Explain that you'll do the profile yourself.
Serena: Right. Because this is all just a favor to me and not a convoluted way for you to keep your eye on Raina and Chuck during Valentine's Day?
Blair: Hmm. I hadn't thought of that. Thank you!
