What have you done with Don Lothario?

In my main save file most of the original premades died off, but then because of threads like this I put some of those families back into my neighborhoods. Right now Don is married to Katrina, but that relationship won't last because he's woohooing Nina on the side. She was distraught at her mother's wedding. I imagine Don will get Nina knocked up and then kinda be forced to stay with her. I don't see them leaving Katrina's house any time soon; neither of them really works. I've planned for Katrina to marry Dallas Winston and take in he and his two sons from his previous marriage. It's gonna end up a full house. Dina and Steve Randle are together now too, so that's probably gonna work out.
