Kiri heard the compartment door slide open again. Surely they could be left alone for a few moments! Raiden was ill, after all! She turned out, still crouching. But when she saw who it was, her exasperation vanished. "Hi Shana," she said with a preoccupied smile. And obviously the girl could see what was up. Kiri gestured wordlessly towards Raiden, then turned around again.

Vanessa, in the meantime, had apparently noticed her glance, because she had got up and was busy tugging on the window locks. After a brief struggle, they yielded, and with a loud whoosh, fresh air entered the compartment.
Kiri, meanwhile, was looking at Raiden again. He really didn't look well. She bit her lip uncertainly, then extended a hand that was shaking slightly and touched Raiden's forehead. At the touch, a familiar tingling feeling, starting at the fingertips, made its way over her entire body. Plunging on boldly, she caressed his face lightly - which was indeed hot. "Poor Raiden," she murmured. Suddenly, she was feeling a little light-headed herself.

Then Vanessa was kneeling next to her again. Kiri hastily removed her hand and watched in silence as the other girl dealt with the other people in the compartment very efficiently. Especially when the strange vial with the blue potion came into play, Kiri was glad that the older student was with them. She'd half opened her mouth to say something to the boy holding it herself, but the situation being as it was, she doubted she would have had much in the way of persuasive force.
The other boy seemed harmless enough. Maybe a little... overexcited.
