Lex was naturally unaware of what happened within the Origin realm. Even though he had searched for Moon's clone relying on his own bloodline, finding even one such facility was incredibly difficult and time consuming.
Although Lex had not completely located all of them, he had to hand over this task to others while he handled more urgent matters. While they could not rely on bloodline to find these facilities, they could rely on traditional means of tracking and searching.
It was not that he did not care, but that he could not afford to spend too much time on this. If he did not handle the many matters that bothered him, who knew when he would also get swept away by a formidable foe?
The Midnight Inn, for all its bluster, was, at any given time, just one big accident away from being destroyed.
But though there was danger, Lex was also making tremendous progress.
