In Alt-dimension, naming a building or business after a living person is illegal, so even if Lex Luthor existed (with that name) and he was basically the same man he is in canon dimension, it's possible that Clark had never heard of him.
Or when Tempus jumped universes he decided to eliminate the competition, so to speak, and destroyed Luthor before he was particularly well known.
Or hey, maybe Luthor actually managed to be a good guy for a change and was off helping orphans in Africa or something!
…
Naw.
Wondering how Clark and Lois will arrange their evening chats now. I guess they could come up with something else, but losing the cannolis will be such a tragedy!!!
