James tries to peek over at Yuu's phone, but never really fully understands what it is, aside from being some Muggle thing sort of like the journals in Wonderland.

"Maybe they're all just stuck wherever they wound up," he says. "When I woke up I was in Hogsmeade, but then it started to feel a bit strange, so I wandered here. Maybe they just haven't gotten to that wandering part yet."

And maybe Yuu hasn't either, but it seems like a gentle enough nudge in that direction.
