Jeremy made up his mind. It was unfair for Mika but this was another chance for his little sister to brush up her skill and improve herself before he could hand in the company to her.
Of course, he knew about her plan to sell some of the shares to Ryn so they could work together. He approved it and even planned to sell some of his shares so that three of them could still own the company and Ryn would feel like one of the owners in the company.
He already ordered Jacob, his personal assistant to proceed with the agreement and all the details he already worked with his assistant so none of the three had any disadvantage when the shares moved.
He told Jason about his decision and ignoring Jason's argument, Jeremy simply cut the conversation. He still needed to call his Ryn and tell her about his decision. And he knew she was waiting for him at home. She would not move without knowing who would go to the shooting.
