Of course, her major hint, at the end of the show, must foreshadow what'll happen next week; at least I'm guessing that it will. But somehow, bringing Zach's/Alex's first girlfriend, back from the dead, is overkill. Perhaps it's the adoptive mother....but wasn't she also supposed to be dead?
They wouldn't be the first ones brought back from the dead on that show! I'm thinking it might be the (previously deceased) father of Zach, (Alex), or the (previously deceased) brother of Zach (Michael). Can't figure out how Janet would know any of the bunch, though. Only in soapland!
