Marlon scoffed, "Then what can he do anyway? He won't be able to do anything just because I attacked his mistress."
"But Sarah said he is already starting a business backed by Vernon Phoenix Gray. What would happen if he becomes extremely successful and tries to destroy all of Grant's family businesses?"
The smirk on Marlon's face disappeared instantly.
He would lie if he said he wasn't concerned about Henry's effort.
He saw Henry as lesser James.
He was less smart, brave, and skillful at managing business. Henry was also easier to control than James simply because he was the son of a prostitute. He understood his position and, thus, had lesser self-confidence and self-worth.
That's why Marlon didn't hesitate to kill James when he knew he had a dumber son he could control.
