If something possesses Zephyr or, Asri forbid, he gets sick, X will know exactly why.

"A school?" It doesn't sound dangerous, but then again, X has never been to a school. From everything he's heard, they can be cesspools of frustration and exhaustion. A more relevant question: "How did he escape it?" The Dreaming could manipulate time, but from the visions X had, it didn't seem like the crew were stuck in a solid place. Maybe they were trapped in a long-term illusion.
