Ah, the old breaking into the pool episode ...

I don't know what Gossip Girl episode this is for but ...

Plot outline: The kids break into the school swimming pool at night to have a party, but someone nearly drowns. In the face of expulsion, a pact of secrecy is formed, which Dan is hesitant to be part of, causing tension between him and Serena. Meanwhile, Vanessa learns about Chuck and Blair's affair; and Lily considers expressing her true feelings to Rufus.

*shakes head* Dan .... Dan *shakes head again*.

The velvet glove of justice is back in action!
