I love these two and I've had this idea in my head for awhile... so here we go!

(I already started posting this on AO3, so the first few chapters will be up all at once then I'll update at the same time)

Prologue

"Do you understand your mission, Agent Martinelli?" Repeated the man in the expensive black suit, looking down at her coldly.

Angie simply stared back at him not bothering to respond. The doctors hurried around her adhering electrodes to her temples, wrists, and the insides of her arms, with a kind of manic frenzy. She assumed they were scared of the man in the suit, worried he might decided to execute the lot of them on a whim if they appeared idle.

Or maybe they were just afraid of her.

A needle jabbed in at the base of her skull causing Angie to gasp involuntarily. Bright flares of pain shot across her nerve system, leaving the ends of her fingers tingling unpleasantly and her chest tight. It felt like being stabbed with an ice pick. Sure, she had endured worse over the course of her career, but that really didn't make it any easier to endure.

"Fuck." She bit out, glaring at the only nurse she could see without moving her head. Angie had been warn repeatedly not to move during this procedure or she might simply die in the chair.

"This better work." Angie met the man in the suit's cool gaze evenly. "How exactly do we know this isn't just going to fry my brain?" The corners of her lips turned up into a wry grin, which he didn't seem to know what to do with.

"We don't." Was The Suit's only response.

"It will work." Assured Dr. Ross confidently from behind her, he had a Jersey accent that clearly wished it was Manhattan. "One flick on the switch, Agent Martinelli and it's hello 1946 for you."

"Fantastic." Angie muttered dryly, her eyes moving past The Suit to the large skull-octopus insignia on the wall behind him. The dead eyes bored back into hers. "Just fantastic."

They laid her chair back carefully and, for the first time since this process began, Angie could properly see the strange instrument on the table beside her. A triangular base of alloyed metal holding up a series of spinning dials, some of which flickered with blue lights, ran a tangle of wires to the electrodes attached to her body. Angie seriously doubted it was earthly in origin. The thought sent a chill down her spine.

The nurses quickly stationed themselves at their various computers and monitors that filled the bleak underground lab. It was so quiet Angie could hear her own heart beating in her chest, and she prayed she was the only one that could. The first rule was always: never let them see your fear. Your fear was a weapon they could turn against you.

Moving up to the table, Dr. Ross made a show of putting on a pair of thick gloves designed especially for this moment. He began turning the first dial on the device, counting off the numbers to the other doctor as he did so. She could hear the scratching of the pin on the paper as the other man - Angie never did bother to catch his name - wrote everything down excitedly. Dr. Ross repeated the process on the next two dials then stopped, his fingers hesitating above the metallic knobs.

The doctor leaned over Angie, his face alight with a disturbing sort of glee. "I imagine this is going to hurt." He said.

Angie's gaze focused in on the red Hydra pin on his white coat, not wanting to look at this face. She continued to stare unblinkingly at those dark skull eyes as Dr. Ross turned the last dial on the machine.

"Hail Hydra!" Was the last thing she heard as the world dissolved into white light. And for some reason it made her want to laugh.

The world compressed and stretched and bent around her. Angie Martinelli felt the weight of the entire universe, and was part of it, for half a second before she opened her eyes again. She had not moved an inch, but the world she was seeing now was completely different from the one Angie had been in seconds ago.

She was standing in an overgrown vacant lot, littered with broken bottles and candy wrappers. Beyond it was a city she could almost recognize as her own beloved NYC. It worked! She took in a gasping breath of different tasting air. Angie couldn't believe it, the crazy ass thing actually worked.

This was New York City 1946 , and Agent Angie Martinelli had only one mission: kill Peggy Carter.
