Tsubasa started, and looked back at her. He fell into line beside her but it was a few moments more before he responded "... I appreciate your concern. There is nothing anyone can do." He knew that Hyuga and Akatsuki were doing their best to save him from having to transform, even though he had ordered them to forget it; and Rin was sure to be desperately anxious when he told her what was happening. Tsubasa felt guilty over causing others to worry, especially when they knew that as a Makai Knight he could have been killed in battle long before this.
