Chuckling at the Flashes, Bruce flew past them and led the way back the the Cave, off-road just past the billboard over the bridge outside the city proper and around the brush and rock where no one would see the car or the impressions on the road.
The secret entrance to the Cave was radio controlled to sense the car as it approached and opened as they drew near, shutting down the security devices, as well. A long paved tunnel served as a driveway into the main Cave and Bruce piloted down, pulling to a stop on the circular dais that extended out over the open central portion of the Cave over the water. Looking down, several stories were visible, each housing its own set up and equipment.
An enormous semi-circle of computers were close at hand, glowing brightly in the dim light of the Cave. Bats cried overhead, some of them disturbed by their arrival, other accustomed to the comings and goings of the master of the house and content to remain hanging in place.
Getting out of his car, Batman left the platform to meet them on the Cave floor. "I'm assuming you want to start with a DNA test?" he asked.
