Finally, they were back on their way to Hogwarts! Kiri had made her rather frosty goodbyes to her parents and aunt at the platform. Try as they might, they had not managed to get her to wear her aunt's robes again (which were now stored all the way at the bottom of her trunk) - it hadn't gone well, her aunt putting on an expression of pouty disappointment.

The train was rocking slightly from side to side as Kiri made her way to a cart in the back - at the station, she'd seen Raiden enter there, and, naturally, she wanted to spend the long ride to Hogwarts with him. In the interests of allergy-curing...

When she reached his compartment, Kiri was surprised to see it crammed with people. The compartments were built for maybe six people, but this one looked as if there was some sort of competition going on - were they trying to beat canned sardines?!
Kiri couldn't see anything, obviously, but from somewhere in the middle of the huddle came the voice of Raiden, which sounded rather strained. She began elbowing her way in, muttering apologies as she shoved and pushed.

Finally, she managed to get to the front. Raiden looked... well, faintly green. Nauseous. "Raiden... Excuse me." She shoved again, then seized his hand unthinkingly. "Raiden, are you okay? What happened?"
