It sounded strange to have one of those in a mental hospital, but then again, it was a lot more normal than that secret passage, or the teleporters. Among various other things.

Though Lloyd's world of possibilities didn't necessarily sound like a good thing to him. As nice as having a key would be, there were a lot of rooms here, and it would waste a lot of time trying to check all of them. But at least there were apparently more than one, so they'd be able to split up to cover more ground.

Kyousuke found himself looking up in surprise when Lloyd mentioned Kratos' name, though. Did that mean he didn't know what a metal detector was either? He guessed that made sense, since Lloyd said they came from the same world, but Kratos had always seemed so sensible and with his head square on his shoulders, so unlike with Lloyd, it was pretty weird to think of him not knowing something like that. That was ... unexpected.

"Castiel?" he repeated, pulling himself out of those thoughts. "No, that doesn't sound familiar." But the numbers here weren't that big, so he'd probably seen him around even if they'd never spoken.
