J.J. (Jimmie Walker) does not appear in this episode.
The second and final appearance of the character of Frank Mason.
Wilona never mentions him again nor is it explained what happened to him since he did mention that he was moving to Chicago. And considering they were in love with each other -it's odd that he would just disappear like he never existed.
One has to think that the producers must have decided to scrap that story-line and just write him off like he never existed.
