The Hummingbird Protocol [Carlos Oliveira x Original Character Fan Fiction]

The snow came softly that morning, the way it always did in Montana—not demanding, just there, settling over the pines like the world had pulled a blanket over itself and decided to rest a little longer. Kira noticed it first through the kitchen window. She was still in her oversized cream sweater and black jeans, her hair half-pinned and falling around her shoulders. She pressed two fingers to the cold glass and watched a fat flake drift past, unhurried. "It's snowing again," she announced to no one in particular. "Mmm," Maria replied, not looking up from the stove. The older woman moved around the kitchen with the quiet authority of someone who had claimed this space long ago. The smell of butter and something sweet already hung in the warm air. "Sit down, querida. Coffee is ready." Kira sat. The kitchen table was round and worn smooth at the edges from years of elbows, morning papers, and card games that ran too late. Mr. Henderson was already in his chair at the far end, reading glasses perched on his nose, turning the page of yesterday's newspaper as though the news might have changed overnight. "Good morning, Mr. Henderson." He peered at her over his glasses. "You have paint on your chin." "That's from yesterday." "Still there." She rubbed harder. Dr. Mizutani arrived next, already dressed for the lab in pressed slacks and a collared shirt, but he'd forgotten the top button again. Kira reached up and fastened it for him as he passed. He patted her hand without breaking stride, heading straight for the coffee pot like a man with a singular purpose. "Cold out?" she asked. "Very." He poured his cup and held it in both hands. He had kind eyes—the sort that crinkled at the corners even when he wasn't quite smiling. Kira had always thought of him like the big pine tree at the edge of the yard: reliably, permanently there. Dr. Smith came in last, slightly breathless, his jacket half on. "I overslept," he said. "You say that every Tuesday," Maria said, setting a plate of toast in front of him. "It's Wednesday," Kira corrected. "Every Wednesday, then." Uncle John—as Kira called him when the lab coats were off—dropped into his chair with a comfortable heaviness and reached immediately for the jam. He was a broad-shouldered man with deep laugh lines, smelling faintly of the cedar soap he'd used for as long as Kira could remember. He winked at her, and she smiled back, sliding a bottle of vitamins next to his plate. The coffee was extraordinary—dark, strong, and hot enough to sting slightly. Outside, the snow kept falling. For a while, the table was quiet in the "good" way, the kind of quiet that meant everyone was content exactly where they were. When breakfast was done, Kira walked her father and uncle to the hallway entrance—the boundary where the warm, lived-in mansion ended and the sterile, white-tiled world of the lab began. Dr. Mizutani paused and turned. Kira stepped in and hugged him properly, her cheek against his shoulder. "Have a good day, Dad." His hand rested on the back of her head, gentle. "You too, hummingbird." She watched them disappear down the hallway. The heavy security door at the end hissed shut behind them, sealing the two worlds apart. By late morning, Kira had settled into the library. It was her favorite room, home to a fireplace that had not once failed her in twenty-one years. After reading for a while, she drifted to the old grand piano. She played the Aria from the Goldberg Variations first, the orderly notes filling the room with a sense of peace. Eventually, she moved on to the piece Uncle John always requested: Rachmaninoff's Prelude in G Minor. She played it without sheet music; the complex, rhythmic chords lived in her hands. The rest of the afternoon was perfect. She baked a chiffon cake that released cleanly from the pan—a rare victory—and shared tea with Maria and Henderson at half past three. Kira curled her hands around her teacup and felt the particular goodness of an ordinary day. She was back in the library by five. The room had taken on the blue-grey quality of a late winter afternoon. She kicked off her boots and tucked a knee up on the window seat, lost in her book. She almost didn't register the alarm at first. Then it was everywhere—a harsh, repeating tone designed to be impossible to ignore. Kira dropped her book, her heart hammering against her ribs. The lights shifted, emergency amber bleeding in along the ceiling. She heard the distant, heavy mechanical thud of the main entrance locking down. "Maria?" Kira called out, her voice sounding small. Footsteps hurried down the hall, and the library door swung open. It was Dr. Mizutani. He was still in his lab clothes, but there was a dark smear on his sleeve that she forced herself not to look at. His face was a mask of controlled panic. "Dad—" "Listen to me." He took her by the shoulders. His hands, usually so steady, had the slightest tremor. "I need you to listen carefully." "You're scaring me." "I know. I'm sorry." He guided her toward the fireplace and crouched to meet her eyes. "There has been an accident in the lab. I have to go back, and I need you to stay here, hidden, until I return for you. Do you understand?" "What kind of accident?" "Kira." His voice was final. "Get into the fireplace. The alcove on the left, behind the screen. You fit there. Do not come out for anyone until I come back for you myself. No one else. Me." He pressed something into her hand—a gold pendant of a hummingbird in mid-flight. It was warm from his pocket. "Keep it close. I love you, my hummingbird." He straightened and turned toward the door, his mind already racing back to the disaster he had left behind. In his desperation to reach her, he hadn't even heard the security gate fail to click behind him. He disappeared into the hall. One hour earlier, someone else had been waiting too — but with entirely different patience. Dr. Michelle Brown had red hair tied back in a bun so tight it looked architectural, with a few wavy strands left to frame her ears. She had a slender nose and wore a shade of red lipstick that looked like a warning. She moved through the lab wing with a predatory grace, looking like she belonged everywhere she went. The coffee station was used by everyone. The micro-needles were nearly invisible. She was thorough, she was careful, and she was done in under four minutes. The first scientist turned at 4:31 PM. Elena was a level 4 scientist. She had been at a general-use computer in the office when she turned, which meant Mizutani and Smith would spend time on level four looking for an explanation that wasn't there. Brown noted this and found it useful. In the shared office, Mizutani and Smith didn't waste time. She watched them from afar, around whiteboards — just a glance, enough. The thumbdrive passed between them with the quiet efficiency of men who had prepared for this. Then they moved, and she let them go. There were other things to handle first. At 4:50pm, the second scream came from level 3. She heard it from across the lab and watched the door to level 4 open — Mizutani and Smith coming out, looking at each other with the particular stillness of men who have just understood something. Level 3 had no T-virus. Level 3 scientists had no access to level 4. They knew what this was now. They ran for the office. Brown moved. She fired at Smith as he came through the door. She missed—but she saw the box in his hands. He scrambled away, bleeding from a shoulder wound, and disappeared toward the Level 5 vaults. Brown tried to follow, but the emergency lockdown hissed into place. Her ID card was useless against the reinforced doors. Smith had opened the Level 5 biological hatches on his way through, putting a nightmare of experimental subjects between himself and her. She turned back toward the residential wing. She reached the iron gate that should have sealed the lab from the house and stopped. It was standing wide open. Mizutani, in his frantic rush to find his daughter, did not close it. The smartest man in the building had let his heart override his training. Brown pulled the radio from her hip. "1730. Retrieval failed. Subject Smith is mobile but compromised. Mizutani has fled to the residential wing." She paused, her eyes tracking the open path. "I'll get his ID card. And the girl. I'll handle the girl." Kira heard the gunshot shortly after she hid herself. It was distant, muffled by the heavy mansion walls, but her body recoiled instinctively. She pressed herself flatter against the cold stone of the fireplace alcove, her knees pulled to her chest. Footsteps approached the library. Measured. Deliberate. The door opened. Kira stopped breathing. A woman's voice, flat and professional, spoke into a radio. "—Not in the library, either. I'll keep checking." The door closed. Silence returned, heavy and cold. Kira stayed absolutely still, one hand closed around the hummingbird pendant so tightly the small gold wings bit into her palm. She waited for her father to come back. He had said he would.
