Very enjoyable!
I’m happy to see Clark returning to a semblance of rationality.
The idea of a ship surprised me. If it were me, I would make sure that:
1. Clark was on-board (edit: in agreement) right from the beginning.
2. The ship be either built for 1 or 3. I can see Lara go back to Krypton now that she’s met her son. Or, I can see Lois accompanying Clark and Lara.
The problem that Clark and Lara have to face is that any trip back to Krypton is potentially a one-way trip. I can’t see Clark leaving Lois when there is a non-trivial chance that he may not be able to return to Earth.
