For a moment, Richard seemed stuck, tugging at the knife with both hands, laughing like it was all part of the game. Nathan took the opportunity and lashed out, driving his foot into his father's knee.
The sudden impact sent Richard sprawling backward, losing his grip on the knife. He landed with a grunt, but even then, his laughter didn't stop. His arms flailed wildly, his eyes still locked on Nathan.
"Nice one, Nate!" Richard giggled, rolling over to his feet with an unnatural agility, as if he were a marionette on invisible strings. "But I'm faster than you think!"
Nathan barely had time to react before Richard lunged at him again, his movements unpredictable and erratic, like a man possessed by something far worse than insanity.
Nathan dodged, grabbing a chair and thrusting it between them, hoping to create some distance.
