The Echo Chamber

The alley was a wound in the world. Even in the daylight that filtered through the grimy fire escapes, it felt wrong—like someone had bleached the colors and stretched the shadows too long. Peter Parker stood beside Doctor Strange, his spider-sense buzzing at the base of his skull like a trapped fly. "You're sure this is the only place a temporal containment unit can stabilize?" Peter asked, adjusting his mask. It was getting harder to breathe through the webbing lately. Strange didn't look at him. He was already tracing a sigil in the air with his right hand, the Cloak of Levitation rippling like a living thing. "The Sanctum's vaults hold many things, but the unit attuned to your specific quantum signature is stored three dimensions over. I can't just portal us there without risking a sympathetic resonance that would collapse this alley into a singularity." "So we're taking the scenic route." "We're taking the *safe* route," Strange corrected, and the golden ring of a portal snapped open, revealing a narrow corridor lined with mirrors. "Follow me. Don't touch anything. Don't talk to yourself in the mirrors, even if you see yourself looking back." Peter followed, stepping through. The corridor smelled of ozone and old paper. The mirrors didn't reflect him—they reflected rain-slicked streets and stars that weren't in his sky. A woman in a green cloak walked past him in a reflection, her face blurred. He looked away. They emerged into a circular chamber filled with floating crystals. In the center, on a pedestal of carved obsidian, sat a small silver pyramid no larger than a Rubik's cube. Strange reached for it. "Careful," Peter said. "That thing looks like it could—" The air screamed. A tear in space opened beside them, and a figure dropped through—a man in a tattered Spider-Man suit, but the colors were wrong. The blue was too dark. The red was almost black. And the mask was torn, revealing half a face that was Peter's, but older, jaw set with a permanent grimace. "You shouldn't be here," the echo said, and his voice was Peter's, but dragged through gravel. "You'll break it again." Peter went rigid. "Who—" "You know who I am. You're looking at him." The echo raised a hand, and a web-line shot out—not from a shooter, but from his palm, organic. It wrapped around Peter's wrist and yanked him off his feet. "You died in my world. You died saving a bus full of kids. And I couldn't save you. Now the multiverse is stitching us together like a bad scar, and someone *wants* that." Strange conjured a shield of orange energy, deflecting a second web-line. "Release him, or I'll—" "You'll what?" the echo snarled. "Apologize?" Peter twisted, firing a web at the ceiling and swinging himself away from the echo's grip. He landed beside Strange, heart pounding. "He's from a universe where I died?" "An echo," Strange said, voice tight. "A memory made flesh. The multiverse is healing wrong—*someone* is pulling threads, and this is the result. Fragments of what was and what never was, all converging on you." The echo stood, shoulders hunched. "The unit won't help you. The rupture is already spreading. You need to cut the cord before it drags every broken timeline into yours." "Who's pulling the threads?" Peter demanded. "A man who remembers dying." The echo's mask flickered, pixelating like a bad video. "He calls himself the Loom. He's the reason I'm here—to stop you from containing the damage. He wants the chaos." Strange snatched the silver pyramid from its pedestal. The echo lunged, but Peter intercepted, tackling him into a crystal formation. They crashed through, shattering glass and light. For a moment, Peter stared into his own dying eyes—and saw the echo smile. "Good luck, kid," the echo whispered, and dissolved into wisps of green smoke. Silence. Strange stood over Peter, the containment unit glowing in his hands. "We have approximately nine hours before the stability window closes." Peter got up slowly, his suit torn. "Nine hours to find a dead man named the Loom." "And to apologize," Strange muttered, almost to himself. "For all of it." The portal opened again, and they stepped back into the alley. But the alley wasn't empty. A crowd of echoes stood waiting—versions of people who never existed, all staring at Peter with knowing eyes.
