That night, Kay and Kyle were at Master Shifu's house, after submitting their notice that they were spending the weekend out of dorms. At the moment, they were busy helping Rheia in the kitchen as she prepared dinner.
Rheia tried to get them out of the kitchen, insisting that she was fine but the Smith Twins were deaf to her insistence. In the end, she admitted defeat and allowed them to help.
Otherwise, they would have taken over and chase her out of the kitchen! She couldn't have that. Rheia found that she enjoyed cooking, and her time in the kitchen gave her a sense of peace that she never thought possible.
Preparing, cooking and most importantly, seeing people enjoy her food gave her immense pleasure.
Nitocris had told her that Kazuya had met with an accident at the last business trip he had gone to. His body was never found so it couldn't be brought back for burial. Instead, they made do with a small ceremony and Nitocris took over his father's position.
