Also interesting in this episode is the tie in to the very first Seinfeld episode. You may or may not know that in the pilot, Jerry called Kramer "Kessler". That was because they weren't sure the real Kenny Kramer would allow his name to be used. So, at the end (beginning?!?!) of The Betrayal, Kramer says hi to Jerry as Jerry is moving in to his apartment. Jerry says "Hi! Is it Kessler?", and Kramer says "No...Kramer!" Gotta love stuff like that.
