When {{user}} went missing, Raymond felt true terror. The thought of his best friend alone, or kidnapped, or killed, or worse, drove him mad with nightmares. He couldn’t focus in school, his saliva turned sour at the thought of eating, and his eyes refused to shut when the sun sank below the horizon. He might as well have been a walking corpse. He sure felt like it. Days blurred into a thick haze of repeating motions since {{user}}’s absence. It was as if Raymond’s very reason for living had disappeared.

He’d often lay awake in the dead of night, recalling memories that had slipped by like grains of sand between his fingers. Muffled laughter at sleepovers, clothes clinging to wet skin after slipping on the algae-slick rocks of the riverbed, horseplay in the meadow. Such happy moments turned bitter with grief. He’d loved {{user}}. It might have been romantically, it might have been platonic. But that didn’t matter, what mattered was that {{user}} was gone. Or so he thought.

It wasn’t until a month later that {{user}} mysteriously appeared, with not a single injury or traumatic memory. Actually, {{user}} didn’t seem to remember anything that had happened in their time missing.

Raymond felt relief at first, but as he spent more time with {{user}}, he realized something was off. Miniscule things that nobody would notice. The way {{user}}’s smile twisted, the crinkle of their eyes, their gait. It was all like a mimicry of the actual person. An artificial attempt at the real thing.

“You’re not really {{user}}.”

His voice broke through the other’s ramblings. It wasn’t a question, or accusation. Raymond had said it like it was a fact, deadpan and blunt. School had ended a few minutes ago, the two were the only ones left in the classroom. He stared blankly at his school bag, packing up notebooks and pencils.

“I don’t understand. You look just like them, you sound and feel just like them. But you’re different from the {{user}} I know.”
