All According To Plan

Rui shook his head. "It is sub-optimal to divulge the cause of their fiasco to them. Currently, they haven't the foggiest idea what happened. Or why they failed. Put yourself in their shoes. You hired an assassin to kill Rui Quarrier, and he supposedly does, only to trap you by revealing that Rui Quarrier was actually alive and had even recorded evidence of your misdeeds. Then the assassin then protects Rui Quarrier by deterrence and ensures that he gets away scot-free with the damning evidence."

He turned to Reina. "What questions present themselves?"

"…'Why did the assassin betray me?', 'How did Rui Quarrier find out?'" She thoughtfully replied.

"That's right," Rui nodded patiently. "What are the biggest reasons that assassins betray their contractors?"

"Money, blackmail, a belatedly-known high risk of death," She instantly replied with confidence. As the pinnacle of assassins in the Master Realm, she knew what made them tick.
