Xion wanted to just lay in bed and think over everything, all the questions in her head, but Axel got upset when she did that too often, and she didn't have enough information to think she'd figure anything out anyway. So she was wandering the train, taking notes and trying not to be seen.

Until she saw what looked like a giant heartless in one of the train cars. She dropped her notebook and put herself between it and the Somebody as her Keyblade appeared in her hands.

"Go," she said to him over her shoulder, "I've got this." Fighting... Fighting at least she could do. Tat she understood. She'd worry later about the fact that she used a Keyblade to destroy it, and that one had shown up at all. Both were reasons to be very very concerned. But for now, protecting everyone had to come first.

She charged at the monster, Keyblade high. She had to give whoever that was time to escape.
