Rustling outside mimicked the static inside Elara's skull. Days blurred into a seamless, grey current, each one carrying away fragments, small eddies of what had once been solid. Marcus sat across the room, his gaze fixed on a point beyond the peeling wallpaper. A familiar posture, yet a strange distance had settled between them, thick as dust motes in the unmoving air. Felt a shift in the way he breathed sometimes, a shallow hesitation that wasn't his. Asked him about the old oak tree behind her childhood home, the one where they’d carved their initials. Marcus frowned, a slight furrow between his brows, then offered a vague recollection of 'a big tree, somewhere green.' Not *their* tree. Tried again, describing the deep scar near the base, the hollow where they’d hidden a time capsule. He nodded slowly, a perfunctory gesture, as if humoring a child’s fantasy. Cold seeped into Elara’s veins. It was like trying to sketch a forgotten face from a smudged photograph. Memories, once vibrant tapestries woven through years, were unraveling thread by fragile thread. An inside joke, whispered in a moment of shared terror, now hung limp and lifeless when she tried to evoke it. Marcus would stare blankly, his eyes holding no spark of recognition, no echo of their shared laughter or fear. He had mentioned a summer camp, a specific cabin where they’d spent two weeks building rickety rafts. Elara remembered the camp, the rafts, the sun-drenched days. But in her mind, Liam had been there, always. Marcus, however, spoke of a boy named ‘Sam’ who’d fallen out of a canoe. Sam. No Sam had ever existed in their story. Sensed the entity in these voids, in these small, insidious gaps. Not a physical presence, but a chill, a whisper of absence that settled whenever a memory failed. It was tearing at the very fabric of their connection, dismantling their shared past brick by careful brick. Found herself staring at Marcus's hands one afternoon. They were strong, capable hands, calloused from years of working with salvaged parts. But for a fleeting moment, they seemed alien, the fingers too long, the knuckles too prominent. She blinked, and they were Marcus's hands again, but the unsettling image lingered. Slightest sound in the next room, a creak that wasn't there, made her jump. Marcus, though, remained impassive, his focus unbroken on the non-existent point on the wall. Was she hallucinating the sounds, or was he immune to them now, perhaps even deafened to their shared reality? Night brought no solace. Dreams were a swirling vortex of familiar faces wearing unfamiliar expressions, of places they’d known twisted into monstrous caricatures. Woke up gasping, the taste of ash in her mouth, unsure if the dream had been a memory or a premonition. Whispered his name, just to hear it, to tether herself to something real.
