Setsura had no evidence, of course. But she has to be careful. Katakura told her that if the shard ends up in somebody else's hands, it would be bad. "Akito, I would like some new jewels," it was a lie, of course. She didn't need any more jewelry. Akito had bought her so much that she didn't know what to do with it.
This answer pleased Akito since he laughed, "Alright! I knew you'd say then, then let's get you ready for the event tomorrow. We have to buy you a nice dress."
...
The following morning, Setsura felt utterly devoid of all strength. Akito got way too carried away dancing. Her gaze fell on the carriage that was going to take them back home. When she saw the face of the Butler, she felt so relieved. Even the faces of some of the servants from Akito's mansion relieved her. She did narrowly escape from death this time.
