Remember when Kramer got that woman pregnant? Whatever happened with that? It's been a while since I saw that episode, but I seem to remember that she was on the verge of committing suicide until the man in the cape saved her. The man in the cape was (I think) representing Frank Costanza in the divorce that never happened.
I think the impregnated woman was played by an "In Livning Color" castmember.
It seems like they just dropped that "spawn of Kramer" storyline without any explanation.

P.S. - In the episode about Kramer passing a stone, Jerry makes a reference to capes. I just saw that ep. recently.
