The stun grenade whirred, a soft, insidious sound that drilled into Ren's skull. Red light pulsed, faster and faster, painting the shadowy archway in frantic, blood-like flashes. Sixty seconds. And counting.
Panic flared on the faces of his new squad mates. Anya, the girl with braided hair, instinctively reached for a weapon that wasn't there. The hulking boy stumbled back, hitting the damp stone. The nervous cadet whimpered, clutching their glasses like a lifeline. Ren, however, remained still, his eyes locked on the device, then on Rivan, the sneering Plata cadet who held them captive.
"It's a diversion," Ren stated, his voice flat, cutting through the rising tide of fear. He didn't look at his escuadrón, his gaze fixed on Rivan's subtly surprised expression. "He doesn't want us to disarm it. He wants us to try."
Rivan's sneer faltered, replaced by a flicker of annoyance. "What are you talking about, Bronce? Just disarm it, unless you want to spend your first night unconscious in the infirmary."
"No," Ren continued, taking a slow, deliberate step forward. His eyes, usually placid, now burned with chilling intelligence as they locked onto Rivan's crony holding the grenade. "The device isn't the real problem. It's the camera." He pointed to a barely visible pinhole lens on the crony's uniform collar, just above a wrist-mounted data logger. "And the timer on that grenade is rigged. It's set to detonate the moment we're scrambling, making us look like incompetent fools on camera, regardless of whether we disarm it or not."
Rivan's smile vanished completely. The crony with the camera device subtly shifted, his hand moving as if to cover the lens. Ren had struck true.
"The real test," Ren's voice dropped to a near whisper, yet it resonated with immense weight in the confined space, "isn't about disarming the grenade. It's about exposing your manipulation." He stared Rivan down. "You wanted footage of Bronce VII failing under pressure, a report to solidify your escuadrón's superiority. But what if the footage shows you attempting to sabotage a First Year squad's orientation, Rivan?"
The red light on the grenade pulsed with frantic urgency. The whirring intensified. Less than ten seconds remained. Anya, the hulking boy, and the nervous cadet stared at Ren, then at Rivan, dawning comprehension replacing their panic. The trap had sprung, but not on them.
Rivan's face was a mask of furious calculations. He had underestimated this nameless Bronce cadet. This wasn't just a pawn; it was a viper. His carefully laid trap was about to ensnare him instead.
"You have ten seconds, Rivan," Ren stated, his voice devoid of emotion, yet dripping with silent threat. "Ten seconds to decide if you want to be known as the Plata Cadet who illegally tampered with a new recruit's orientation for a cheap laugh, or if you simply 'guided' us effectively, by not letting your 'test' escalate into an official incident."
The red light on the grenade was a frantic strobe. Five seconds. Four. Three.
Rivan's eyes darted between Ren, the pulsating grenade, and his crony's camera. His carefully constructed image, his escuadrón's reputation, hinged on this moment.
Two seconds.
"Disarm it!" Rivan snapped, his voice tight with barely suppressed rage, nodding sharply at the crony with the grenade. "Lesson learned, Bronce. Next time, move faster!" The crony, startled, fumbled for a split second before pressing a hidden button. The red light vanished. The whirring died.
Silence.
Rivan's eyes, burning with a dangerous mix of hatred and reluctant respect, locked onto Ren. He had been outmaneuvered, exposed, and forced to back down in front of his own cronies and the academy's supposed weakest.
"You may have won this round, Bronce," Rivan snarled, his voice a low growl. "But Aegis is a long game. And you've just made yourself a target." He gestured sharply to his cronies. "Let's go. Our time is too valuable for these… exercises."
As Rivan and his Plata escuadrón stalked away, their retreating footsteps echoing ominously, Anya stared at Ren, her mouth slightly agape. The hulking boy looked at him with a mixture of awe and fear. The nervous cadet, slumped against the wall, now had a strange, new glint in their eyes.
Ren merely watched Rivan disappear into the deeper shadows. He had achieved a minor victory, exposed a bully, and gained fleeting respect from his escuadrón. But Rivan was right. Aegis was a long game. And by saving his escuadrón, Ren hadn't just made Rivan an enemy. He had finally, and irrevocably, stepped onto the battlefield.
"Come on," he said, his voice flat. "Our quarters aren't going to find themselves."
As they began to move, the nervous cadet, still leaning against the wall, whispered, "How did you… how did you know all that?"
Ren didn't answer, didn't even look back. He simply kept walking, his mind already three steps ahead, anticipating Rivan's next move, and the academy's next hidden challenge. He knew this was just the beginning. The scent of ozone and ambition still hung heavy in the air, a constant reminder of the battles to come.
