Gigi and Rex get the horrifying news (though in Llanview, not very surprising news) that Stacy is pregnant after her one night stand with Rex! It's time to play the blame game, and Rex decides it's all Gigi's fault. If she hadn't lied to him in the first place, he never would have slept with her sister. Stacy says it's not over between them yet -- and everyone starts dealing with the fact that a new little bundle of Balsom may be joining the fray!
All this, PLUS: Jessica starts having visions of Nash AND gains a stalker; Cole begins his undercover work with John; Dorian and Blair mourn their lost love lives; and perhaps most important of all -- Lindsay's back!
