Rose’s heart hammered against her ribs as she stepped back, clutching her phone to her chest though she knew its uselessness. The relentless roar of water filled the hallway, swallowing the children’s anxious voices as she fixed her gaze on the woman standing before her. For a heartbeat, Lei—no, the doppelganger—stood perfectly still, her eyes meeting Rose’s in a moment of unblinking, watchful silence. Then her smile twitched, the practiced warmth melting into something unreadable and cold.
Khiara clung to Rose’s skirt, her small hands trembling. The boys, Hezekiah and JJ, hovered in the doorway, eyes darting between the adults, uncertain if this was still their world or if they’d slipped into a nightmare. Zia pressed against her brother, mouthing silent questions, uncertain terror reflected in her wide eyes.
Rose took another step back, subtle, careful, unwilling to startle the impostor but needing space. That smile, stretched and unyielding, followed her. "You’re frightened," the not-Lei said, her voice perfectly mimicking the gentle cadence of their friend, but now every syllable rang hollow, slightly off-pitch like a warped recording.
Water sloshed across the tiled floor, soaking into Rose’s slippers. Every instinct screamed at her to run, to scoop up the children and flee, but she forced herself to stand her ground. The doppelganger’s posture remained relaxed, but her hands rested on the edge of the counter, fingers splayed as though bracing for movement—hers or Rose’s, it was impossible to tell.
"The house is flooding," the woman said softly, her eyes shining with a false sympathy. "We should try to stop it, don’t you think? The children mustn’t be frightened."
Rose could barely swallow. Keep her talking, she thought. Don’t give her a reason to act. She slid her foot back, inching herself between the children and the not-Lei. "I think we all need to leave the bathroom now," she managed, voice shaking but firm. "Maybe… maybe we can call for help outside. Our neighbors—"
The doppelganger shook her head gently, almost pityingly. "There’s no need for neighbors. It’s only water. I’ve been through worse, Rose." Her tongue lingered over Rose’s name, tasting it, as if savoring the access it gave her to this moment.
A sudden crash sounded from below—the unmistakable sound of something heavy falling. The children gasped, Khiara clutching tighter. The doppelganger’s eyes flicked downward, then back to Rose, and in that instant, the mask slipped. For a fraction of a second, pure calculation—sharp, ancient, inhuman—flashed across her face.
Rose’s knees nearly buckled. She recognized, now, the predator that stood before her. Not-Lei took a step forward, hands raised slightly, palms outward to feign calm. "Let me help you, Rose. Please," she said, her voice soft, her smile returned, as if nothing had changed.
But everything had changed. The water was rising. The threshold was breached. Rose could no longer feel the floor beneath her bare feet.
Then, from the hallway—a voice, thin and trembling, barely audible over the torrent: "Mom? What’s happening?" It was JJ, his small face pinched with fear.
The doppelganger tilted her head, her attention sliding from Rose to the children. The air between them tautened, every movement suddenly heavy with consequence. What Rose did now would shape everything that followed. In the drowning house, with her children at her back and the impossible stranger before her, every second counted.
The doppelganger took another step, hand outstretched, as if to comfort—or to seize.
