Nao smiled. "I can understand that, but I've never been to Narita Airport. I mean, this is my first time on a plane. It's all a little exciting that I need something to take my mind off it, you know?" She tried to make small talk, but it was like the words passed right through him, as if he was registering something else in his mind as he suggested the teacher might need help. They watched as Mizuho walked away. That girl was trouble with a capital T and Nao didn't like her, even if she was the closest of the other girls to her in age. She seemed like a brat. In a big airport like this, it made sense to Nao that Mr. Ralph didn't want Mizuho wandering off, but Mr. Ralph seemed especially concerned about such matters, more than what seemed necessary as it was clear to Nao that Mizuho had just gone to the restroom, albeit in the most disrespectful way given Mr. Ralph's rules.
"I'll get Ms. Oono first. Mr. Ralph will just get mad at me too if I go after her by myself," Nao said, putting her headphones away as she went to get their other supervisor for their trip, pulling her aside as discrete as she could be. "Ms. Oono, Mizuho-chan ran off to the bathroom. Can you go get her before Mr. Ralph notices and gets upset?"
