I'm so tardy with this, but I've been trying to think of stuff to do with it.

L will stop by for the demonstration and he will probably have Karako with him. His main interest will be in observing the machine (and wondering if it has anything to do with how resurrections happen on the ship, an idea he won't be forthcoming with).

What happens when they come by? Does the machine seem shady in any way? Etc. etc.
