The final family I had living on an empty lot is the Hart family. I brought them to Twin Towns because of their daughter, Bebe.
I think their house is the most successful I made yesterday.

I discovered Dorie and Gus were divorsed and Gus was in a relationship with Fiona McIrish. So I moved him out of the Hart household and in with Fiona.
Now I've returned to the Hart home and discovered Dillon Lawless, Bebe's boyfriend, has move in with them.
EDIT: I discovered it was Dillon Lawless and not his older brother Orion who has move din with the Harts.
