Ooooh, fun one. Even got an idea. Sadly, time's not cooperating in the immediate future.
As for the idea: Based on today's ubiquitous surveillance and the advances in AI, the cameras in Lex Tower could be watching and the building's AI taking note of the various events happening. For instance Lex threatening Clark with a sword and the Clark*) firing a gun at Lex's face while being dressed in bright clothing, to be continued up to Lex imprisoning his would be attacker in a cage in the building's cellar.

*) Yes, an AI can be guileless and with the marvel of facial recognition, there is not sense for the AI to consider them to be separate people.
LOIS:
Are you implying that even a *computer* is smarter than me?
