Prince Brian and Prince Charles both looked in Aurora's direction. 

"Menial work?" Prince Charles was confused. "We have enough workers here to help you if you need it. There's no need to let this dirty trash to do your work."

"Perhaps, there are some confidential matters?" Prince Brian asked this instead. HIs eyes gleamed faintly as he looked at Aurora with some interest. "If other workers were to know those, they have to be silenced and it might be a bit troublesome. But for this one, you don't have to worry so much. Once he crosses the line, it's very easy to draw one's sword."

In other words, if Prince Lester knew too much, Aurora could kill him without the need to worry about the consequences. 

It was simple as that. 

"Oh right." Prince Charles clapped his hand and then grinned. "Just do that, Cousin Aurora."

"Should I ask for permission from His Majesty?" Aurora asked.
