Great timing. This throws some plausible deniability Superman's way. After all, nobody is going to accuse him of being Resplendent Man's father. People are going to start wondering what's going on. Is Superman going to be honest with Lois about how Resplendent Man got his powers? In the show, he didn't want the idea of his powers being transferable to get any publicity, and he didn't trust Lois not to print it. But I think in this situation he needs Lois as an ally and he can't afford to damage her trust in him.
You've certainly piqued my curiosity.
