Thanks!   
sigh...better days...

This was a few months after Jack Smith joined Kay Alden as headwriter. I loved this period of the show... things had been revving up from a boring spring and early summer.

It was a pretty good month with the poolhouse fire mystery continued onward and of course Victoria's slap that was heard around the universe but also rather ugly with Paul's rape of Christine on the night she got engaged to Michael as well as the Brad/Olivia stuff heating up. Andy came back to bring Paul and Diane back down to Earth. 

I couldnt stand Kelly Kruger’s Mac. By far the worst Mac recast. Her scenes were consistenly unwatchable. I was so glad to see her leave the next summer.

When did Raul's parents debut? 2002 or 1999?

2002.
