Undying Fidelity

Summary:

Sigyn feels like her whole world lost meaning when Loki took his last breaths in front of her. When the time heist comes to be, Sigyn has no qualms against volunteering. She would be willing to die if it meant being able to kill Thanos. She volunteers to return to 2012 New York with Tony, Steve, Scott, and Bruce. Her reasons weren’t selfish, she promises. Chaos ensues.

Work Text:

Sigyn had felt like the world moved in slow motion from the moment the life had left Loki’s body. The snap had only made things worse. It had been 5 years since she had seen pretty much anyone other than Thor and sometimes the residents of New Asgard. She kept to herself more often than not. 

It was almost ironic how Loki had spoken of undying fidelity shortly before his life had been snuffed out. Meanwhile her own undying fidelity had seemed to leave her cursed with never-ending grief.

The talk of time travel had gained her interest almost as soon as the idea was pitched to the team. Asgard was an option but she knew that wouldn’t be the best option for her. Odds were that in the time they would send them back to, the residents would still think that she was dead.

Her heart had done a funny sort of flip-flop as they talked about heading back to New York. Her stomach sank even lower as an image of Loki was pulled up on the screen.

“So Sigyn will come to Asgard with myself and the rabbit,” Thor began to announce.

Her brown eyes drifted over to where Rocket had, once again, slapped himself on the forehead in frustration. “As much as I would love to go back to Asgard, I believe my skills are needed in New York.”

“You sure that’s such a good idea there, Frosty?” Tony quirked an eyebrow. 

“Are you sure it’s such a good idea to have two Hulks in one place? No offense, Bruce.”

“She’s right.” Steve spoke up, “I know what you’re thinking, Tony, and it won’t happen.”

Sigyn locked eyes with Tony for a moment before the older man relented. “Fine. But any funny business and I’m leaving your ass back in 2012.”

She hated travel. Whether it was through space or time, it all sucked to her. All the hair on her arms seemed to stand up inside of the suit as she shared one last worried look with Thor before they were off. Something was different about hurtling through space when you were a lot smaller.

“We all have our assignments,” Steve began as Sigyn stood up straighter and began to glance around. She knew he was around but more importantly she could feel him again.

A loud roar jolted her from her thoughts as she took a step closer to the men she had traveled with. There was the Hulk. Or the old Hulk. However time travel worked, there was the previous Hulk from that time smashing up a car like his life depended on it. 

A small smirk crept onto her face as she caught the embarrassed look that Banner had on his face. That was the champion she had seen back on Sakaar. A total wild animal. 

This Bruce, however, didn’t seem to have any of that in him anymore. Sigyn’s head tilted slightly as the rest of them watched the green man try to get back into how he was before. “Well, he’s a little confused..” She muttered.

“But he’s sure got the spirit.” Tony joked. “Let’s roll.”

Sigyn didn’t even have to ask where they were going. Sure, they had talked about it in the plans but she felt like she was almost in a trance as she scurried after Tony and Scott as Steve split off from them with a flash of a reassuring smile.

After not using her magic for what was probably years, she was surprised that she didn’t stumble as she landed inside the Stark tower right after Tony. As she slipped behind the stone wall to hide from their old selves, she couldn’t help but sneak a peek. Did her hair really look like that from behind? Ew.

“If it’s all the same to you,” her heart leapt into her throat, “I’ll have that drink now.” Tony gripped her arm a little too hard. Her eyes narrowed as she shot him a look.

The 2012 version of her let out a quiet snort of laughter. She remembered the look that Natasha had shot her. “What?” She heard herself say. 

“All right, get him on his feet.” The younger Tony Stark ordered. “Uh-uh. Not you, princess. Come on, Point Break. Get him up. We can all stand around posing up a storm later. By the way, feel free to clean up.”

“Wow I almost forgot how much of an ass you were, Stark,” Sigyn hissed through gritted teeth.

“At least I had style. Speaking of! Mr. Rogers, I almost forgot. That suit did nothing for your ass.” Tony shook his head in mock sympathy. 

Steve practically sounded like he was rolling his eyes. “No one asked you to look, Tony.”

Sigyn raised an eyebrow and shrugged in agreement as she caught sight of Captain America. That suit really was terrible. 

“I think you look great, Cap. As far as I’m concerned, that’s America’s ass,” Scott called out over the line.

“C’mon.” Sigyn whispered, “No one likes a…kiss ass.” She smirked as Tony shot her an appreciative look.

“Who gets the magic wand?” Nat asked.

Thank god that Tony knew his way around Stark tower more than anyone even after years of not living there. Sigyn’s eyes narrowed as she watched the Hydra agents in disguise begin to file into the apartment from their new hiding place.

A laugh nearly slipped out as she watched Loki transform into Steve from across the room. “I mean honestly,” he joked as he turned back into himself, “how do you keep your food down?” 

“Shut up,” Thor snapped as he placed a lock over Loki’s mouth. 

“I wish I could tell you dearest,” she heard herself say as she watched the scene unfolding in front of her. In spite of Loki being in chains. A prisoner. She watched herself grab him gently by the arm to lead him into the elevator with Thor almost like when they used to walk through the gardens together. “But then I would have to kill you.”

Tony’s grasp on her shoulder pulled her out of the moment as he pulled her back towards the window. The plan flooded back into her mind as she began to plummet backwards towards the ground. She let out a grunt as she was finally able to regain her own balance to drift back towards the ground without Stark’s help.

“What’s-a matter, Frosty? No knight in shining metal armor today,” Stark joked. 

“You burn my hair with those flaming feet of yours and you won’t make it back to the future,” she hissed through gritted teeth as the small green embers flickered from her own fingers as she continued on a quick course back to the ground.

“Looking fresh, Stark,” Sigyn mumbled as she walked up beside Tony in her own security outfit. The only difference was her long blonde hair hung out from under the helmet. “Almost didn’t recognize you without the extra few inches of metal.”

“That really hurts me, you know. I would think for someone so old you would want to be a little nicer to the younger gen-ow!” Tony rubbed his arm as he received a hard pinch. 

“Shut up. Here we come,” she swallowed hard as she spotted herself again out of the corner of her eye. She walked side by side with Loki with her head held high. It was amazing how she could walk like that when she remembered how she’d felt. She had known that Loki had pretty much signed his own death sentence and yet still she walked beside him with pride. He was her husband and she was loyal to him. It was her gift and her biggest curse. 

“Thumbelina, do you copy? I’ve got eyes on the prize,” Tony chirped into the ear piece. 

“I’m going inside you,” Scott whispered back after a moment. Sigyn’s eyebrows shot up as she shot an amused glance at Tony. 

Sigyn flashed him a delicate smile. “I didn’t realize I would learn so much about your personal life today, Mr. Stark.”

“Quiet down, Glinda. We don’t want Elphaba to hear you.”

“May I ask you where you’re going?” Pierce’s voice made her skin crawl as she watched him approach the group. 

“A bit of lunch and then Asgard,” Thor answered cheerfully.

“Perhaps a stop for gas. I hear mileage on the Bifrost is killer these days,” past Sigyn cooed as she shot a look back at Loki over her shoulder. 

Pierce stood up a little straighter. “I’m going to have to ask you to turn the prisoner over to me.”

Sigyn could almost feel her throat close up all over again as she watched herself take a defensive step back towards Loki. Her hand came to rest a mere inch away from the handle of her knife.

Tony whispered beside her, “Easy, Sig. We know how this goes, right?” He paused. “I see what you mean by the whole fidelity thing though but the victory thing?”

“Hush!” She hissed back as she watched Loki turn slightly with an annoyed look in his eye. The woman turned to face the other way quickly as chaos seemed to be breaking out behind them again. Pierce had always been an asshole that much was sure. She wished she could’ve said she were surprised when she found out he was Hydra all along. Her stomach churned as more thoughts raced through her head of what they would have done to her husband if they’d gotten a hold of him in the first place.

Sigyn squeezed her eyes shut tight as she heard the crackle through the ear piece and a different sort of chaos broke out. “Oh my gods! Stark,” she heard her own panicked voice and the two of them turned to see herself abandon Loki and reach a hand out to steady Tony.

“Aw, you do care.” 

Sigyn resisted the urge to punch Tony in the chest for good measure. Her heart leapt as the suitcase with the tesseract spun towards them. Her pulse quickened as Tony leaned down to pick up the case and her gaze wandered for just a moment. Loki had noticed. 

“Good job, meet me in the alley,” Tony mumbled as he began to quickly exit the building. She was just about to take a few steps to follow when another explosion happened. Except it wasn’t so much of an explosion as it was a rampaging green monster busting down a door.

“Oh shit,” she hissed through her teeth as she skittered back. Stark landed at her feet with a groan but a softer noise drew her attention. A soft tinkling noise and her gaze flickered to the case. The tesseract. 

Time seemed to stand still again as Loki glanced over his shoulder and locked eyes with her. A confused look crossed the upper portion of his face for a moment before he glanced back towards the chaos ensuing over past Tony. He had noticed.

With one last look back at her, he knelt down to pick up the tesseract. She thought she heard Tony grunt something but her feet carried her quicker than she could ever remember running before. 

Just as Loki stood again, Sigyn came within one step of him. The sudden noise behind him made him turn once more. She gritted her teeth into a grimace as she placed both her hands on the tesseract. Sigyn fully intended to yank the damned thing right out of his fingers but before she could, she felt a strange sensation. A wall of blue and black smoke engulfed the pair of them.

She hated space travel.

Loki landed in the sand with a loud grunt despite the muzzle still over his mouth. The tesseract was still in his grasp. Had he even really seen what he thought he had?

A loud scream echoed through the air around him. His eyebrows raised as another portal seemed to open in the sky right above him. A figure all in black fell through it; arms flailed and legs kicked as the ground seemed to raise to meet them.

Another loud grunt left Loki, this time a more pained one as the smaller figure landed right on top of him. 

Quickly, the woman rolled to the other side and let out a quiet groan as she pulled the helmet from her head. With a fluid movement, the black object was tossed aside into the sand before she flopped back onto the sand. A grunt beside her alerted her to the presence of the man. Without even a glance to the side, she reached over and pressed a hand to his mouth to deactivate the muzzle. 

“Lovely of you to drop in, Sigyn,” Loki coughed as he took a deep breath.

Sigyn let out an annoyed grunt. “A pleasure, as always.”

Loki caught her gaze out of the corner of his eye as he rose to a sitting position. “You should have just let me take it,” he hissed through his teeth.

Sigyn let out a heavy sigh as she sat up and shrugged off the heavy black bulletproof vest and jacket she wore. “And let you cause more chaos and destroy more cities?”

Loki glanced over at her. A nearly imperceptible look of nervousness crossed his face before he smirked at her. “Who says that’s what I was going to do with it.”

Sigyn rolled her eyes as her gaze flickered forward to a small group of people that were moving slowly towards them. “I would like to think I know you better than you know yourself. Whatever you do, we’re in this together now.” She wasn’t about to lose him again. Not so soon.

“I’m positively touched,” he cooed.

“Til death do us part, darling.” And even after.
