Good point, Tank. I probably don't have to tell you how much *I* want Lois and Clark to be together. But what's preventing them from being together in SR is Richard, not the kid. And as I already said, Richard gave me the creeps... precisely because he was such a severe impediment to Lois and Clark being together.
On the other hand, if you consider what was done to Lois and Clark (or Lois and Superman) in the four Christopher Reeve movies, and bear in mind that SR is supposed to be a sort of sequel to the first two CR movies, I guess Singer and the DC/Warner people were just looking for a way to keep Lois and Clark/Superman apart.
