It sounds to me like Superman is flat out lying. I'm betting he was captured by the government, and they've been brainwashing him or something like that all this time. It's a frightening prospect.
I love the direction you're taking this, and I love how Lois can read his body language and knows his habits and see that something's off.
It makes me wonder whether he doesn't remember being Clark (either because he's been brainwashed or because he's a clone), and that's why he hasn't visited his mother, or maybe he has some tracking device he can't get rid of, and he's not being Clark to protect his identity and his mother.
I'm eager to see how this plays out.
