Hi Dandello!
The note that day had read 'Perry, we're fine but we can't come home – Lois.'
Intrigue. Looking forward to seeing if they went forward or backwards in time. Also, shouldn’t he recognize Lois’s handwriting? Hmm…or do they know they can’t come home for another couple of years and had the first note delivered in the (nearer) future, akin to Back To The Future 2?
Superman had disappeared for several days after the Kents' vanishing. When he returned, it wasn't the same man.
Oh, so they are in the past and Superman’s now older? Or is it actually Baby Jordan?
Within days of the appearance of the new Superman, Jerome and Lois Clarke of Crosstime Industries announced they were moving their company headquarters from Los Angeles to Metropolis.

Then, when LexCorp disintegrated, the Clarkes were poised to pick up the pieces on the West Coast. It was as if they'd had prior knowledge of Luthor's fall and had just been waiting for it.
I can’t, for the life of me, figure out how they could *possibly* have known.
It was known that Lois Clarke was a close friend to Laurel Tideman of Tideman Industries – they supported many of the same issues, were on many of the same boards.

Lois called out to her son who appeared to be staring through the wall. "Jon, remind Jordy we still need to get a handle on the sound pressure waves. That's just annoying."
Teaching him to go supersonic without the boom?
So, why wait for 6 months? And they didn’t reach H G Wells before his death in 1946? I’m guessing letting some of the bigger death tolls happen over the past 50 years probably was a bit of an issue for Clark, huh?
LOIS: Yeah, you wouldn’t believe how fussy a baby he could be.
Their working behind the scenes must be really challenging. After all, they can only change things that don’t mess up the future. One wrong life saved could have dire consequences indeed.
And did Lois have a pseudonym for writing investigative journalism pieces submitted to various big news papers, possibly even the Daily Planet?
CLAKR: Yeah, you wouldn’t believe how fussy a baby she could be.
