The moment I touched the mirror, the world around me shimmered and wavered. My apartment dissolved into a swirl of colors and sounds, leaving me standing on the edge of a city that looked… familiar, yet wrong. Skyscrapers twisted into impossible angles, and the sky had streaks of violet I’d never seen.

A voice called my name—my own voice, but sharper, confident, and full of purpose. I turned and froze. Standing a few feet away was Scarlett Johansson—my exact double, though something in her eyes told me she was more than just a reflection. She smiled, a wry, knowing grin.

“You’re late,” she said, stepping closer. “We don’t have much time.”

“Wait… who are you? How are you me?” I stammered.

She gestured at the chaos around us. “I’m you, in another universe. And our worlds are collapsing. Something… something we both did triggered it. We need to fix it—or both of us will cease to exist.”
