What happens in the last episode? I heard Tia and Tamera find their dad and go on a trip with him. And does anything happen with Lisa and Ray? They're so cute together :D

Lisa got married to another man, and the episode was about that

To me the last episode of this show is one of the better series finales I've seen. I don't think Ray and Lisa belonged together, and apparently so did the producers because they seemed to be orbiting towards each other in season 4 (the last year 4 show has Ray's wife's ghost showing up) but at the start of year 5 Viveca is on the scene. Ray and Lisa were better off as friends than lovers IMO and the Victor guy was Ok for Lisa. Also in the finale they had a scene that was reminiscent of the pilot so they brought it full circle, plus Roger came back and the girl's father was in it along with that bus!
