In season 4, there was the continuing story of Joey, Kathy and Chandler.
Chandler ended up with Kathy ("TOW Chandler in a Box").
But I don't remember ever hearing about her again, or about them breaking up. What happened? Or is this just a case of the writers/producers not really following up on a storyline?
I'm reading some episode guides/transcriptions on the Web, but that's a bit slow going (though fun).
Thanks for any light you can shed on this!
