Hi Virginia,
I'm happy to see that you are catching up.
Yeah, I had to have him call Clark something, some king of nickname because Jack is the casual type and besides they are coworkers.
They are confident that the story will pan out.
There are two things 1) the time he spent with Lois in both universes and 2) to him it's history. Lex Luthor was not around in his time at the DP, but after talking to Lois he could have gone into the morgue and pulled back copies to read about the events.
The only way he would have had a good handle on the timéline would have been that because the events occurred somewhat earlier in the Alt universe.
