Time stopped.
For Isaac, he was simply grabbing a shirt. For Cole, a trigger was pulled. The boundary was breached. The physical contact bypassed the rational, tired, civilian part of his brain and hot-wired directly into the reptilian survival mechanisms forged in the worst places on Earth.
The shift in Cole was instantaneous and terrifying. He didn't flinch. He didn't pull away. In a fraction of a second, the exhausted, hunched posture evaporated. Cole's right hand shot up, his fingers clamping onto Isaac's wrist like a steel vise. It wasn't a practiced martial arts grip; it was the brutal, crushing grip of a man who had held onto helicopter skids over black water.
Isaac paused. The smile faltered on his face. He tried to yank his hand back, expecting the old man's grip to break easily. Cole didn't let go. His fingers dug deeply into the tendons of Isaac's wrist, finding the nerve bundle and squeezing with mechanical, merciless force.
Isaac gasped, his eyes going wide. "Hey, let—"
Before the word could leave Isaac's mouth, Cole moved. He didn't stand up like a normal person; he exploded upward, driving forward off his right leg, completely ignoring the screaming pain in his bad knee. He didn't throw a punch. Punches were for rings and cages; punches broke hands.
Cole drove his left forearm straight up, completely bypassing Isaac's guarding hands. The hardened bone of Cole's forearm crashed into the soft tissue of Isaac's throat right beneath the jawline. It wasn't a strike; it was a displacement of mass. Cole stepped into the center of Isaac's balance, driving his entire body weight forward and up.
Isaac's feet actually left the ground. His breath caught in a sickening, wet choke. His eyes bulged as his airway was suddenly and violently compromised. All of his theories about pacing and dominance vanished into a blinding panic of suffocation.
Cole maintained his crushing grip on Isaac's right wrist, twisting it sharply outward. The pop of the elbow joint was audible in the sudden, dead silence of the gym. Isaac let out a strangled, high-pitched scream that died in his throat as Cole slammed him backward.
They crashed into the heavy dumbbell rack. Metal clanged against metal. Isaac hit the floor hard, his head bouncing once against the thick rubber mats.
Cole didn't step back to admire his work. He didn't pause to pose. The moment Isaac hit the floor, Cole dropped his weight directly onto Isaac's chest, his knee driving savagely into Isaac's solar plexus, expelling whatever air was left in the younger man's lungs. Cole's left hand immediately pinned Isaac's throat to the mat, his thumb pressing hard against the carotid artery. Cole's right hand pulled back, tightly balled into a fist, suspended inches above Isaac's face.
The transition from a quiet man on a bench to a predator pinning its kill took exactly 2.4 seconds.
The gym was absolutely silent. The students were frozen, their mouths hanging open. Nobody moved. Nobody breathed.
Cole knelt over Isaac. The older man's face was completely devoid of anger. There was no rage. There was no triumph. His eyes were dead, flat, and hollow—the eyes of a great white shark rolling back in the water.
