Your Superman is anything but "not real" and Lois is clearly responding to him.
She said sorry so Superman will think better of her.
Yet again Clark comes off poorly.
She knows Clark and Superman are completely different people. She is growing closer with Superman and has the start of a friendship with Clark.
But clearly this Superman and Clark won't leave her feeling in love with two people. She won't have any trouble choosing.
And even if Clark were to put on the suit today, she'd know he wasn't the Superman she knew, but a substitute of some sort.
It is like getting to know twins, after really getting to know one of them you don't confuse them with each other.
Superman is years older, more mature, more self assured, radiating confidence. And so much more comfortable with Lois then he was as Superman the first time around.
When he leaves and Clark has to step into the role he will be a poor second. Everyone will notice. Lois will know it is a different man in the role, others will wonder what happen to make him so much less.
I'm sure the papers will have a field day. he will seem to have regressed. People will be very concerned about his well being.
His beginner mistakes with not be seen as beginner mistakes but as symptoms of his regression.
Wells really shot himself in the foot this time.
