ECHOES OF THE TERMINAL FLOOR

The polished porcelain tiles of Terminal 3 felt like sheet ice beneath Leo’s temple. Sounds reached him in warped, underwater pulses: running footsteps, frantic flight announcements, and the low, vibrational rumble of an idling jet out on the tarmac. Right beside his ear, the heavy panting of Officer Mark Vance’s German Shepherd, Rex, sounded like an exhaust pipe. Mark remained crouched on both knees, one gloved hand clamped tightly to Rex’s harness handle, the other hovering centimeters above Leo’s torn olive parka. The boy’s breathing was shallow and uneven.

Blood formed a crimson delta on the white tile, seeping from beneath Leo’s left side. Mark leaned closer, his dark beard twitching with every measured breath as he tried to project an immovable calm against the echoing panic of fleeing travelers. "Stay with me, buddy," Mark muttered, pitching his voice beneath the sirens beginning to blare across the terminal PA. "Eyes on me, Leo. Help is here."

Leo’s eyes fluttered, glassy and unfocused. His lips parted, trembling, releasing a broken whimper that cut through the noise of the terminal. He wasn't crying loudly; he was freezing from shock. Mark unzipped his own heavy duty jacket slightly with a free thumb, assessing the boy's wound without shifting his weight. A clean, targeted puncture wound cut right through the canvas parka near the ribs—not a scratch from a fall, not shrapnel from luggage. It was an assault.

The female paramedic, Sarah, skidded across the tiles on her knees, her medical pack slamming down beside her. Behind her, Dr. Bennett lunged forward, throwing off his stethoscope to press sterile gauze directly against the bleeding tear in Leo’s side. Leo let out a sharp, breathless gasp of pain, his small fingers clenching Mark’s tactical cuff.

"Pressure applied," Bennett barked, sweat already beading along his forehead under the airport’s harsh fluorescent strips. "Pulse is thready, 140. He's bleeding internally, Mark. We need him loaded onto the gurney thirty seconds ago."

Mark did not release the boy’s grip. He kept Rex locked tight between his knees. His gaze swept the upper mezzanine where silhouettes paused behind dark glass before dissolving into the crowds. The scent of ozone and copper was heavy in the air.

As Sarah prepped an IV line, Leo’s trembling hand suddenly shifted from Mark’s sleeve. With the last reserve of his fading strength, the boy pushed his fingertips deep into Mark’s open palm.

Mark glanced down. Wrapped around the boy's bloodied fingers was not a toy or a ticket, but a heavy, tarnished silver locker key stamped with an unfamiliar airline crest.
