As I suspected. I have been attempting to map out the heart of the Barge, but it's buried and inaccessible, for obvious reasons. Is the Admiral a symbiote pilot?

A living ship, with a memory and emotions and an incredible urge towards freedom at any cost. Crichton would know more about them than I, having lived on one. While it is true that Peacekeepers have been capturing Leviathans for some time, I'm told that their behavior in captivity does not mirror that of a truly free ship.
