Shining the flashlight around, John attempted to get some idea of where they were. All he knew was that he, Tasha, and Harper had been descending for a while now, with no sign of either a bottom or any other light sources.
Sighing, John called out, "Yeah, you're right Harper. This is getting us nowhere. Screw it, I'm jumping."
Bracing his legs against the wall, John slowed himself to a stop. He exhaled slowly, and released his left hand's grip on the wall. Falling backwards, he pushed against the wall with his legs, propelling himself into the center of the shaft.
Quickly accelerating, John gave a command to HK. The battle-bot released its master's arm, and returned to its original shape. It then latched onto John's legs, shifting its body around his feet, forming a pair of boots.
