Katrina didn't want Randall standing in her house so she was not willing to help him with this business idea he came up with. "Randall, stick to the business you have now and get out of Lockwood-"
"I'll give you a cut. Make you a business partner," Randall said, knowing it would get her on board with the plan. Just like him, she loved having more money and though she was now a Baroness, he doubted this side of her changed.
Randall asked around about her family before he approached her. He learned about her dead husband, her stepdaughter marrying big, and the debt she was left with. He had to applaud her for looking good while her life was falling apart.
