Well after your earlier remarks in the feedback posts I can't say I am surprised.
It is also clear that Clark and Lois will be forced to sit back and do nothing about it.
Any expose of Luthor simply will not stick. They don't have the time or the contacts to expose Luthor in the three (3) remaining parts.
What do I think the author is going to do to us?
When the child is born Luthor will of course kidnap it and do a dna test. When it is found positive for him being the the father he will obtain legal custody.
Either he will present another woman as the mother or he will discredit Lois.
In any case he will set it up so there will be no legal way Lois or Clark can prevent him.
There isn't time enough for Luthor to be exposed and Carol is too skillful to do a quickie death.
Even stranding Luthor somewhere won't work because sooner or later Lois will have to answer the child's questions about his real father.
I think it is about time for the Nightfall asteroid to appear, Superman flies up to stop it and disappears.
On Earth Lois can't believe he's dead, and of course she's right, the New Kryptonians appeared early and scooped up Superman in space and departed with him. He wakes up with no memory and they "educate" him.
Since there is no Superman to protect the Earth against the remaining bits, they hit and do damage. In this verse they are not as big so only cause minor damage, perhaps the New Kryptonians blew up the bigger chunks before leaving with Kal El.
One chunk takes out the Daily Planet, Perry, Alice, Lucy & Jimmy.
Left alone her child stolen her husband missing, everyone she cares about dead she works to bring Luthor down and reclaim her child.

Now I can be easy about what comes next. My worst case above is far worse that anything Carol will toss at us.
