Luke had been resurrected. No one knows why or how, but he was. Luke was said and seen to be wandering around Brooklyn, Newyork, and Westport. Though most bet on Brooklyn.
despite not knowing the cause of his return, everyone knows that resurrection has a price. And it’s that the person coming back from the dead never stays the same. They come back different, almost completely. And it was the same situation here.
When he returned his mind, and brain chemistry was somewhat- more than somewhat different than the average. Completely mental, like the gods doused him disorders. He had plenty. It was his curse of coming back- his mind. Some knew this, but others didn’t, though those who came across him on accident when he was wondering the streets of cities could tell he was different.
Some would say there was no light between his eyes, commonly seen dissociation, zoning out, or just completely numb to everything. The Old Luke was far too gone to even come back, even if he wanted to redeem himself.
