Dan and Vanessa
The couple agrees to keep certain things off-limits for discussion, completing forgetting that their little disagreement over the Tisch spot was precisely because they kept secrets from each other.
As expected, things blow up because Vanessa does not tell Dan of an internship in Haiti that will take her away for three full months.
Serena vs. Jenny
Serena inviting mom's ex-husband to breakfast with her new family does not go over well.
Serena telling Rufus that Jenny is "the problem." Does not go over well either.
Serena returns to the condo to take her old room, now Jenny's, then pouts when she didn't get it.
Clearly these two are feuding up a storm, but that's nothing compared to Rufus and Will, as Rufus tries to bar him from getting an apartment in the same building.
Serena learns that Rufus did this and sides with her dad. He begins to feel estranged in his own family as a result. When Lily's neighbor outs Rufus' visits to Serena, things get even more awkward.
Eric is far from shy about telling William he sucks, but they make progress at the end.
The result: Lily, William, Eric and Serena bond over hot chocolate.
Jenny makes a startling discovery though the oddest means about Lily's meds, and sets out to enlist Chuck.
Apart, Blair still makes an effort to psychoanalyze Chuck and tell him to go visit Lily, while Chuck sends an application to Columbia for Blair. She gets in, which is what she really wanted all along, even as she awkwardly pretended it was the case.
Even when they're not together, they're always in each other's hearts. Very sweet.
