Mickey O'Connor of TV Guide has this mini-Gossip Girl spoiler / commentary in the website's Q&A today about Dan and Rachel, as well as Chuck and Elle ...
Q: Please tell me the student-teacher sex storyline on Gossip Girl will be short-lived. Talk about cliché!
A: While "hot for teacher" isn't exactly breaking new narrative ground to begin with, here's my thing: Rachel isn't even that hot, and neither is the chemistry she shares with Dan Ho-Humphrey. So I'm with you, they should put this story to bed, so to speak, as soon as possible. And it looks like they're going to - in a very surprising way.
The bad news: Chuck Bass' hooker-with-a-heart-of-gold from the Eyes Wide Shut party turns up again like a bad penny. Emphasis on bad. And pennies.
