Great Xpectations - S4.E6

Andie gets accepted into Harvard in advance, but accomplishing what should be the biggest thing in her life doesn't exactly makes her happy. She decides to explore different paths in her life by going to a rave. In the party, Drue gives Jen drugs, and she gives it to Andie. She tries ecstasy, which has a reaction with her anti-depressives and makes a disastrous combination, which almost leads her to death. Mitch and Gail decide to keep their baby, and things get awkward during the celebration when Gretchen brings Pacey and Joey with her.
