I think the smallest daughter (the one played by Raven Simone) is a closet sociopath. Had the series continued, we would have seen Cliff weeping on the steps of the Courthouse while Sam Waterson held a news conference and Lenny Briscoe dragged the little kid through the hallways of justice, handcuffed and screaming.

Clair would have attempted suicide (only to be rescued by that bitchy doctor on ER - the one with the crutches), Theo would be dealing Crack (as evidenced by his cameo on Law & Order: Criminal Intent) and the rest of the kids would have bailed for Montana to start a commune.
