Summary: After going back in time to return the infinity stones and deciding to stay with Peggy, Steve has created an alternate reality. This is my take on what happened in that reality. It will basically follow various of the movies, but with some changes. Two of these changes include Steve and Peggy's two children: Natasha Sarah Rogers (Sarah) is three years younger than Tony Stark and is two years older than her brother, James Anthony Rogers (Jamie). Both of these children inherited their father's super soldier serum.
1980, Stark Residence
Everyone fell to the floor as the explosion rocked the building. Years of training and battle caused Steve to instantly jump to his feet and carefully analyze the situation. Howard Stark was picking himself up and helping his wife Maria up as well. Peggy was sitting on the floor carefully checking Jamie for injuries.
"Howard?" Steve asked.
"It came from the lab." The words had barely left Howard's mouth before Steve was running for the basement. He got down there in record time to a sight that made his heart stop. The lab was completely destroyed and Tony (who thankfully seemed to be uninjured) was sitting on the floor, cradling Sarah's limp body in his arms.
"U-uncle Steve!" Tony cried on seeing him.
"What happened?" Steve urgently asked as he knelt beside the children, checking Sarah's weak pulse.
"I told her not to touch it!" Tony exclaimed, tears streaming down his face. Steve put a hand on his shoulder.
"I know. Were you hurt?" Tony shook his head, swallowing hard.
"I was on the other side of the door."
"Good thing I had those reinforced." Howard remarked as he walked in. He shoved a pile of smoking equipment off of a table and turned back to Steve. "Put her here."
Steve carefully picked Sarah up and carried her to the table, gently resting her on it. Tony nervously followed, wringing his hands.
"Will she be okay?" He hesitantly asked.
"Probably, she's a tough one." Howard's tone was a little too light to be natural, but Steve didn't comment on it. "What did she touch?"
"That thing." Tony said, pointing at one machine in particular. "It made this big sphere of glowing light and she touched it and it exploded." Howard and Steve exchanged a worried glance.
"What does it do?" Steve asked.
"I'm not sure yet." Howard uneasily replied. "It's a piece of strange tech that S.H.I.E.L.D. found and asked me to analyze."
"What's going to happen to Sarah?"
"I'm afraid I don't know that either." Howard paused for a moment, thinking. "I have another, smaller lab upstairs. Bring her up there and I'll take a look at things, see what I can determine."
"Fine, but you get to explain this to Peggy and Maria." Steve told him, scooping the tiny, unresponsive figure up into his arms.
A/N Consider this fair warning. This fanfic will be updated when I have inspiration. I hope to update at least once a week, but no promises. And yes, Sarah has other powers now. I'm not going to try to list them all here as I'm still exploring them myself, but flight is definitely one of them. And the cover photo is what Sarah looks like.
