On Dawson's 16th birthday, he, Pacey and Andie follow her therapist's advice and throw themselves into an unabashed night of recklessness where both Dawson and Andie get drunk at the jazz club and end up on stage singing the blues. Meanwhile at the Leery house, Joey is organizing a surprise party for Dawson. But the longer the guest of honor is a no-show, the more she is subject to surprises of her own. Abby and two of her girlfriends crash the party and taunt Jack over his recent 'coming-out.' Jen and Ty finally face up to their potentially irreconcilable differences in which they break up for good. Also, Gayle and Mitch come to decisions about how to raise their son in light of their divorce.
