Anyone read Superboy 19?
Basically, in an alternate future Supes and Lois have a kid. Then the kid dies and later revived by someone who hates Metas.
A lot more happens, but I just wanted to focus on where the kid comes from- An alternate future where Clark and Lois get together. What if that alternate reality was actually the Pre-New 52 earth. That would make the kid the son of Preboot Supes and Superboy a clone of Preboot Supes' son. I know in the flashback that Supes is not wearing his classic costume but that could be easily attributed to Harvest getting events slightly off during his history studies.
I doubt events will play out in that direction, but it could make for interesting story material.
nice vid celebrating Superman's 75
and Geoff Johns explaining why Superboy prime seems so powerful in IC which it was a theory I had when I read that comic 😄
