My own take on why the Enlightener was trying to expose Nice would either be:
He found evidence of cover-up with Nice and the Hero Smile incident. Cause indications and screenshots of that has been circle both here and Twitter. Even LH0 has been teasing about dark turn Nice possibly committed.
He is a petty paparazzi troll. He was probably jealous of Nice's personage and status as a hero that he maybe believe digging up or fabricating dirt would bump his own ranking.
Hopefully we get more Villains similar, in motivation, trying to expose the Hero Commission being picked up by the Spotlight Organization. It adds a layer of dark gray, if Spotlight is mostly trying to expose the hypocrisy in the Commission.
By making heroes essential brands, and having their own villains on payroll within agencies, I certainly can say that it would be interesting if Spotlight is composed of the former Golden Age of Villains and they are feed up with how they themselves have been pushed out of the spot light.
*Ba Dum tss*
But real talk, we'll probably learn with time, probably in the episode focused on Hero Tower.
man why was enlighter even looking into nice. he wasn't just trying to dig up dirty laundry, he was framing it as exposing nice for the good of the public. he even looked into the mistreatment of contract companies by nice('s pr team). i feel like we all glossed over the part where treeman legit fucked over lin ling's previous company for no other reason except to cover its own ass after og!nice dies.
obviously enlighter is framed as the antagonist (and he also is the antagonist) but like what's his motive? he seems genuinely convinced that nice is this goliath figure he has to fight against, but he somehow never entertains the idea that nice could be just as constrained by his trust value as enlighter is, or that nice is also beholden to treeman as an employee. i'm so curious about this guy. what does he know about og!nice that we don't?
