The laptop screen glowed, illuminating Amelia’s face with an eerie light. She hadn't meant to snoop. Really, she hadn't. Just a quick peek while he was in the shower. But there it was, a document titled "Project: Amelia." Her fingers, usually so deft at knitting, now felt like lead weights. She clicked the mouse.

A wave of heat washed over her, making her cheeks burn. She felt a strange tingling in her fingertips. She closed the lid with a snap, the silence of the apartment suddenly amplified.

Her breath hitched as she heard the water turn off. She scrambled to put everything back in place. He emerged, towel-wrapped, humming cheerfully. "Hey, babe," he said, oblivious. "What's up?" She managed a weak smile. "Nothing," she croaked, the word sounding foreign.
