Peter WHY...

The abandoned railway lair stood silent under the soft glow of sterile lights, its concrete walls a fortress of stillness as Peter Parker (MC) and the alternate Peter Parker stood near the workbench. Peter (MC) leaned against the edge, his red-and-black suit, mask off, a half-empty bottle of chocolate shake in hand, while the alternate Peter, clad in the borrowed black-and-red suit, paced slightly, his sharp features set with a thoughtful resolve. The air hummed faintly with the lair's equipment, the freezer holding Green Goblin's corpse a grim fixture against the wall.

The alternate Peter stopped, turning to Peter (MC), his voice steady but edged with decision. "I've been thinking," he said, his hands flexing in the suit's gloves. "It's time for me to head back to my Earth. Been here long enough, and my friends need me."

Peter (MC) nodded, setting the shake down with a soft clink, his grin easy. "Yeah, figured you'd say that," he said, crossing his arms. "You're good to go—bones healed, swinging like a pro. I'm cool with it. Been one hell of a ride having you around."

Back to his Earth, Peter (MC) thought, his mind flicking to the chaos of Green Goblin's invasion. Makes sense—guy's got his own battles. Glad he's patched up. The alternate Peter's recovery had been swift, his resilience a mirror to Peter's own, and the lair had served its purpose.

The alternate Peter smiled faintly, glancing at the borrowed suit. "Thanks, man—for everything. This suit, the lair, pulling me out of that mess. Saved my ass back there."

"Keep it," Peter (MC) said, gesturing to the black-and-red suit with a nod. "A gift—one Spider-Man to another. Looks good on you—better than sitting in my locker."

The alternate Peter's eyes widened, a grin breaking through. "Seriously?" he said, running a hand over the fabric. "That's… awesome. Thanks—I'll wear it proud." A gift? he thought, warmth cutting through his lingering tension. This guy's solid—more than I expected. A piece of his Earth to take home.

"You earned it," Peter (MC) replied, his tone light but firm. "Anything else you need before you bounce?"

The alternate Peter hesitated, then glanced at the freezer, his expression hardening. "Yeah," he said, his voice dropping. "Green Goblin's corpse—I'd like to take it with me. Back to my Earth. Gotta tie up loose ends—make sure this doesn't spiral."

Peter (MC) raised an eyebrow, then shrugged, his grin fading to a thoughtful nod. "Fair enough," he said. "Take him—less mess for me to deal with. He's all yours." Corpse on the move, he thought, his gaze flicking to the freezer. Smart—keeps it contained. I have already collected some tissue samples and blood from him.

The alternate Peter stepped to the workbench, picking up the Siege Perilous—the crystalline artifact glowing faintly green, its edges sharp and arcane. "This'll do it," he said, holding it up as he pressed a hidden catch. A low hum filled the lair, the air shimmering as a portal ripped open in front of them—a swirling vortex of green light, pulsating with energy. "Back home," he murmured, his thoughts racing. Time to face my Earth—Goblin's done, but this isn't over there.

He moved to the freezer, its frosted surface glinting as he gripped the handle and pushed, the wheels squeaking faintly as Green Goblin's body—still pierced by the glider shard—rolled toward the portal. With a firm shove, he sent it through, the freezer vanishing into the vortex, swallowed by the green glow. Good riddance, he thought, a weight lifting as the portal pulsed.

Peter (MC) stepped forward, raising a hand in a casual wave. "See you, man," he said, his voice warm. "Stay safe out there—kick some ass for me."

The alternate Peter turned, pulling his mask down, his grin visible through the fabric. "You too," he said, his tone steady. "Thanks, Peter—catch you in another universe, maybe." He's alright, he thought, a flicker of gratitude settling in. Got a brother out here—hope he's good.

With a final nod, the alternate Peter stepped toward the portal, ready to cross back, as Peter (MC) watched, his wave lingering as the green light flared.

The last shimmer of light fading where the alternate Peter Parker from Earth-1610 had vanished with Green Goblin's freezer-bound corpse. Peter Parker (MC) stood motionless, his red-and-black suit catching the sterile glow of the lair's lights, his mask still off, revealing a face etched with a mix of relief and calculation. The hum of equipment a faint pulse as he stared at the empty spot the portal had occupied. 

He's gone, Peter thought, his lips twitching into a faint smirk. Back to his Earth, none the wiser. Perfect.

He stepped back from the center of the lair, his boots scuffing the concrete as he retreated to the side wall, his gaze sharp and deliberate. 

Time to check the real prize, he thought, his fingers brushing against a nondescript tile near the workbench. He pressed it firmly, a soft click echoing in the silence as a hidden panel slid open, revealing a recessed shelf seamlessly built into the wall. The shelf gleamed under the light, holding a small, locked case—a secret he'd kept from his alternate self. With a deft twist, he opened it, unveiling a row of test tubes nestled in foam, each filled with dark red blood, labeled with cryptic markers. Beside them sat a few sealed containers of tissue samples—Spider-Men's blood , collected by Green Goblin across dimensions.

Peter's smirk widened into a full smile, his eyes glinting as he ran a finger along the edge of a test tube. Gotcha, he thought, satisfaction curling in his chest. The real deal—swapped 'em out before showing that fake batch to Earth-1610 Pete. Destroyed the decoys right in front of him—genius move. He'd played it smooth, letting the alternate Peter believe the DNA samples were destroyed, a calculated deception to keep his plans under wraps. He's got no clue I kept the good stuff—thinks it's all gone. Sucker.

His thoughts raced, ambition sparking as he stared at the samples—blood from Spider-Men across Earths, each a potential key to power. These are gold—Goblin was onto something, he mused, his smile sharp. Extract the traits, enhance my abilities—speed, strength, senses, everything. I'll be more than just Spider-Man—I'll be Ultimate. The lair's silence felt like a conspirator, its security a shield for his scheme. Only thing left is the gear—Vera's still rounding up the equipment. DNA sequencer, bioprinter, all of it—just a matter of time.

Peter closed the case with a soft snap, sliding it back into the shelf, the panel sealing shut as he pressed the tile again, the secret vanishing into the wall. Patience, he thought, his grin lingering as he stepped back, the lair's stillness wrapping around him. 

Few more days, maybe weeks—then it's game on. This blood's my ticket—Goblin's loss, my gain. He turned, the test tubes' promise burning in his mind, a quiet thrill settling in as he paced the lair, the snowy Queens night outside oblivious to the plans brewing within.
