Cold water soaked through the worn fabric of the duster jacket. Rain fell in thick, heavy sheets, drumming against the concrete of the Sydney mall parking lot. Underneath the concrete ramp, a small patch of damp, oil-stained dirt offered no real protection. Lucas pressed her bare soles into the muddy grit. Shivering, she dragged a broken wooden stick through the mud, carving intricate, repeating spirals over and over. Every line had to be perfect. If the spirals aligned, maybe the noise in her head would stop. Beside her, Barnaby shivered too. The scruffy terrier mix pressed his wet, warm flank against her hip, a solid anchor in a world spinning out of control. Lucas reached up with a trembling hand, gripping the plastic pendant of her chewed necklace. She bit down on it, letting the familiar rubbery resistance ground her. Overhead, the massive mall exhaust fans hummed. It wasn't just a hum; it was a physical weight, vibrating through her teeth, shaking her bones. To anyone else, it was background noise. To Lucas, it was a physical assault. Every sensory detail arrived at maximum volume. Air pressure shifted, warning her of an approaching storm front three minutes before the first drop fell. She knew the exact cadence of the traffic on the nearby highway, a rhythmic drone that suddenly broke with the screech of distant brakes. Footsteps splashed nearby. High heels clicked on wet asphalt, a sharp, metallic sound that made Lucas flinch. A woman holding a bright yellow umbrella stopped a few feet away, her brow furrowing as she took in the sight of a shoeless teenager huddled in the dirt. "Are you alright, dear?" the woman's voice cut through the hum, sharp and intrusive. Lucas froze. The stick slipped from her fingers, rolling into a puddle. She wanted to say *I'm cold, my feet hurt, I can't find the bus*, but her jaw felt wired shut. Her throat squeezed tight, locking the words inside her chest. "Bah... bah-buh?" Lucas babbled, the sound slipping out dry and cracked. She tried to force her vocal cords to shape the words, but they shattered into a rhythmic, nonsense chant. "La-la-la, go? Up? Up-up?" "Excuse me?" The woman took a step closer, her heels clicking louder on the wet ground. "Do you have someone with you? Where are your shoes?" Panic flared hot in Lucas's chest. She fumbled in the deep pockets of her oversized duster jacket, her numb fingers brushing against her AAC device. She pulled out the rugged tablet, its screen already speckled with raindrops. With a desperate swipe, she tried to tap the icons for *Help* and *Scared*. Moisture on the glass confused the touch sensor. The screen flickered violently, jumping from folder to folder, refusing to register her frantic fingers. "No, no, no," Lucas whined, a high-pitched hum escaping her nose. She rocked back and forth, Barnaby whining in sympathy, his tail giving a hesitant, worried wag. Desperation took over. Lucas reached out and grabbed the woman's coat sleeve, a silent, begging plea. "M-muh? Go-go?" she squeaked, pointing toward the bright entrance of the mall, then to her own chest. Her eyes pleaded for understanding, searching the woman's face for any sign of connection. Startled, the woman pulled back, her eyes widening in alarm as she snatched her sleeve away. "Don't touch me! Please, just stay there. I'm going to get help." Help was a terrifying word. Help meant people. People meant eyes staring, hands touching, and the inevitable, crushing weight of their expectations. Lucas pulled her knees to her chest, burying her face in the damp fabric of her duster. She pressed her plastic headphones harder against her ears, but the silence they offered was an illusion. The foam pads were soaked, squelching against her temples and amplifying the sound of her own rapid, shallow breathing. Within minutes, the world exploded into chaos. Wailing sirens tore through the rainy afternoon, a high-pitched, warbling shriek that sliced straight through Lucas's skull. Blue and red strobes cut through the gray downpour, bouncing off the wet asphalt in a dizzying array of neon light. Two police officers scrambled out of a white sedan, their heavy boots splashing through the puddles. The sheer volume of their arrival felt like a physical blow to her chest. Lucas whimpered, pressing her hands over her ears, her fingernails digging into the plastic casing of her headphones. The lights flashed against her closed eyelids, turning her inner world into a pulsing, painful red. "Hey there, buddy," one of the officers called out. His voice was booming, designed to project over the siren's fading wail. "What are you doing out here in the wet?" Every word vibrated in Lucas's chest like a subwoofer. She couldn't breathe. The air felt too thick, smelling of wet dog, exhaust fumes, and the sharp, metallic tang of ozone. "Don't come closer," she wanted to scream. Instead, a series of clicks and soft chirps escaped her lips. She rocked faster, her forehead pressing against her knees until it bruised. Rigid structures of the outside world had no room for someone who couldn't fit their neat little boxes of questions and answers. They wanted a name, an address, a simple explanation. Lucas had none of those things to give right now. "We just want to help you. Can you tell us your name?" the female officer asked, kneeling a few feet away. Her voice was softer, but it still carried the weight of authority. Barnaby growled, a low rumble of warning from deep in his throat. He stepped in front of Lucas, his small body tense, guarding his human. "Easy, dog," the male officer cautioned, his hand hovering near his belt. Terror clawed at Lucas's throat. She wanted to tell them Barnaby wouldn't hurt anyone, that he was just scared, but her voice was gone. Her mind scrambled, trying to find the sequence of sounds to make them understand. Rain poured down harder, a relentless drumbeat on the metal roof above them. Lucas felt the shift in the air, the sudden spike of electrical tension in the atmosphere. As a kind-faced officer reaches for her, Lucas's vision blurs into a kaleidoscope of red and black, a chilling premonition of a shattering window, yet no window is in sight.
