It was reported in the Boston Globe today that the episode will be the following:
Jerry, Elaine, George and Kramer see a car getting carjacked. Rather than report it, they go to the restaurant and laugh about it. In New York, that's illegal. They're all brought up on charges and in the courtroom, all of the characters from the past figure into the storyline and speak out against their characters. Meanwhile, it's also rumored that Elaine ends up marrying Keith Hernandez... but, beyond that, nobody knows how it'll end.
