Kakashi:

Kakashi wrote out his report to the Hokage while Ryuishi showered. The spa day had been a bizarre experience for him, and he wanted to get the details right for the Hokage. Maybe he could get bonus pay for having to put up with such ridiculous things? Even if it had been oddly relaxing and refreshing, and – nope, he will not do it again. Definitely never again.

Ryuishi had been in the shower for a while, and should be out soon, but then again, Ryuishi seemed to have an inordinate fondness for his shower, and may spend more time in there just to throw him off or annoy him. Suddenly, Kakashi felt a disturbance in her chakra, and soon after there was a twist of chakra that he recognized came from a summon returning.

Her features were a tightly controlled mask at first glance, but Kakashi could read the utter fury and bloodlust that lurked just beneath the surface when Ryuishi emerged from his bathroom. She quickly and mechanically packed her belongings, turned to him, and said, "Trigger, out of the village, now." He calmly began to lead her out of the village. Asking her about the trigger would likely make it worse, and it was best to get her away from Konoha as efficiently and quietly as possible. Kakashi had seen her act as a capable kunoichi; he'd seen her act as a harmless civilian; he'd seen her try and relax and just be a person; but now he was seeing how she could have been the one to devastate a hidden village. They didn't need a repeat performance to occur in Konoha. Though they would be able to stop her, damage would be unavoidable, and the consequences of subduing her would likely be disastrous for the village when her network of people and connections became aware of the situation.

Did her effort to control herself mean that she actually cared about their "friendship" and by extension, Konoha? Or was there something more to this? After all, he knew that she seemed to have been extremely close to her teammates in Kiri and she cared more about them that she did about him, at this point. At least, that's what he thought. Had she been triggered and no one was nearby to restrain her? Had she simply not cared enough for Kiri or her teammates? Or had she put so much faith in her teammates that she felt that she could rampage through Kiri and not need to worry about them or their reactions?

Did her effort to control herself have emotional or logical reasons? Though Ryuishi had at first appeared to be unlogical and highly driven by her emotions, Kakashi had begun to realize that she was actually very calculating and could be manipulative as well. Whatever her reasons for controlling herself, this served as a reminder of why his mission was so important for the village's safety and well-being. Without his presence, she may have lost it right there in the middle of Konoha. What news had she received that triggered her, anyway? He would need to keep an eye out for possible triggers and try to avoid them when she was around. Every time he began to slip up and relax around her, something happened that reminded him of just how dangerous she could be and how precarious his situation was. At least now she was safely out of Konoha and on her way to being some else's problem, though now he had to write up another report for the Hokage, so in a way she was still his problem.
