It occurs to me that, had Vatman had a twin brother that aged normally, he would be about 2 by the time Lois and Clark are planning their wedding. What if a Superbaby clone was found in the aftermath of Luthor's downfall and, thinking he was a regular baby, the state let someone adopt him?

"It is a remarkable dichotomy. In many ways, Clark is the most human of us all. Then...he shoots fire from the skies, and it is difficult not to think of him as a god. And how fortunate we all are that it does not occur to him." -Batman (in Superman/Batman #3 by Jeph Loeb)
