Louis was placed in front as Alex and Yun Fao followed closely behind, they had no idea what to expect, but nevertheless they all knew they were in for quite the experience. As soon as they left the cells, the feeling of weakness was eliminated, however they knew that they weren't strong enough to fight their way away from this guy, so they had to hold on a bit.
Walking through the tunnels was a little bit unsettling, because there was not a single soul in sight. Come to think of it, during the time Alex was connected to khan, there was also not a single soul in sight, except for the cell where a man was being tortured, but even then Alex did not remember seeing anybody torturing the man, his limbs were just being cut off, it became obvious that this place was just as freaky as the underground prison they had escaped from.
