Minoru was off training for the American Ninja Warrior Finals, leaving Isamu to wander the plaza alone, lost in thought.

He'd been working long hours at the IRIS analyzing and testing the drug samples he'd gotten from a Ministry lab in Jack's world. Part of the cocktail they used to control their genetically-modified soldiers. He felt like he was closer than ever to answering questions that had bothered him since his first year in the Nexus - where do telepathic and empathic powers begin in the brain and what structural or neurochemical anomalies prevent someone from perceiving them?

But that wasn't the question he was bringing to the plaza.

No, something else from the visit to that lab was on Isamu's mind.

"...what would you do if you found another world's version of you that has committed morally reprehensible acts in the name of the same values you hold dear?"
