[Suddenly, something comes back to his memory. People had indeed attempted this before. And it had worked. But...]

...That might not take too long. Though the Malnosso didn't set up secure cells in the tunnels, I believe someone else made the attempt. When the Medic vivisected someone named Klonoa.

I have not been down there to examine them yet, but I have my doubts they'll be secure to the degree we desire. First thing is to evaluate them and then strengthen them as needed.

By the time that's done I should have a plan to draw the Remnants into the open.

[Of course, Batman doesn't know Lloyd's skill at craftsmanship. The cells might very well be excellently made..]
