How does this sound? George will stay in his new apartment, since the "living with parents" routine lasted long enough. Thus, he'll keep the job with the Yankees to afford the apartment. Elaine will move in with Jerry (where else would she go?), and have a disastrous job search. Jerry will find someone "just as good" as Rachel. However, after a few weeks Kramer's karma will mess up everybody else's, with massive unforseeable consequences.
In any case, we have a few months to speculate.
Also, the change in George's and Elaine's appearances throughout the season finale was wonderful. Their clothes, grooming, and body language kept pace beautifully with the changing turn of events. Those two can really act.
BTW, is there a candy called Ju-Ju's, or whatever it was?
