It was the person who had told her that he was cheating with the company's profits and he was a close friend of Charles so he spoke up freely. Charles stepped forward to speak against this person as he could not accept anyone speaking against his daughter but Rachel held her arm and said with a broad grin on her face "Dad let me handle this and I promise to give you a thank you gift for trusting this company to me. You just need to enjoy a good show."
Charles knew that his daughter was up to something and he trusted her with his life so he didn't interfere and let her handle it because when she was confident about something the person in front of her was meant to be scared to death.
