Sprinting at the maximum speed he could without using his powers, Jack detected three more entities forming- Clones, by the looks of them. The original energy signature was still running, but Jack was gaining. "There's gotta be a way to cut him off..." Jack said to himself. Just then, BB brought up the city sewers maps in his Heads-Up-Display inside his helmet.
He imagined exactly where his adversary would be on that map, and then ducked into a side tunnel of the sewers. If he ran through them quickly enough he'd emerge right in front of the guy. He willed his kinetic energy to flow to his body, he felt the energy coursing through his veins, and his speed began to increase. He felt himself clocking what he estimated to be up to fifty miles per hour while he sped through the tunnels, and finally emerged in front of his opponent.
"You should know, you can't hide from me. I was always the best at hide and seek in school." Jack said, raising his pistols to his opponent. "Give up. Unless you'd like to receive a lead sandwich, which I'm fully willing to deliver."
