Author's Note: I do not own any of Marvel's characters, just borrowing for funsies. This story was inspired by an AU gif set on Tumblr, who ever made that in the first place is awesome. I'm marking this as complete because I probably will just keep this as a drabble, though I do have some ideas about where this story could go so we'll see. Hope you enjoy and please leave a review! I love constructive criticism!
Loki and Thor stood to the side of a secluded hallway. Loki watched as Thor fidgeted increasingly with Mjolnir the longer they stood waiting for Sif to bring Thor's beloved Jane Foster. The fact that they were in the act of committing treason would be obvious to anyone who saw Loki standing out of his cell. Loki's back was toward the arriving couple and as he turned he was stricken with shock. How could it be? 'Sigyn' he almost said aloud but instead schooled his features. It could not be yet he watched as the love of his life strode toward him accompanied by Sif. It couldn't be her he kept telling himself. He had watched her die, gurgling out her last words while drowning as her lungs filled with blood, "Promise me you'll come find me again? When I wake up?" He had searched for her for decades going on centuries only for her to find him.
Except that this was Jane, Thor's woman. He had been so distracted by her familiar appearance that remembering who she was now stunned him almost as much as seeing her in the first place. Jane looked exactly like his late wife. If this woman was not Sigyn she was no doubt her reincarnation. Would she recognize him? Would she have the same personality traits, same mannerisms and intelligence that he had so completely fallen in love with?
He watches as recognition fills her features, "You're…" She did recognized him! Sigyn's past life's memories must have been incredibly strong whispering to Jane about Loki showing her glimpses of him. But this was still Jane, not Sigyn, best to start with a formal introduction, "I am Loki, you may have heard of me" from those deep voices in the back of your head that recognize me that are telling you that you are finally home, Loki finished the thought to himself.
Jane suddenly hits him across the face hard. His whole head is whipped to the side. "That was for New York." Jane bit out.
Right, how could he have forgotten that he invaded her planet? That's why she knew him. Had she really just hit him? He turned back to face her and he couldn't help but chuckle to himself. Yes this was definitely Sigyn's reincarnation. Their brief interaction left him with no doubt. She was audacious, she was unafraid to stand up against a God, she was beautiful, she was his Sigyn. He turned to Thor with his trademark mischievous grin, "I like her" he said, 'and I will have her again' he left out.
