I do not own avengers or any marvel character.

Soulmate AU no civil war or infinity war.

Tony was going through some of his father's old records when he found an old 10mm movie. just like the one he was given about the arc reactor. But this time there was a note.

Tony if your reading this then I'm sorry my son. Please forgive me. What we did was for the best for you and her. – yours and hers farther, Howard Stark.

He reread the note for what felt like hours. Within minute he had a projector set up ready to go when Pepper his own soulmate came in his lab. "Tony its late. What are you doing?" she saw that he was holding back tears and rushed to him.

"I think I have a sister somewhere." He handed her the note and waited for her reaction.

"oh my god tony I don't know what to say."

"stay with me while I watch this please. Friday lock it down."

"of course,". Friday secured his lab as pepper sat by his side. Slowly and even cautiously he started the projector.

Howard was sitting in a very plan room with the SSR logo behind him. "Tony if you are watching this then I'm most likely dead. Which would also mean that I did it." He laughs shaking his head. "I must have recreated the supper solider formula. We know hydra has infiltrated are government and we are trying to fix that but if I'm dead then we failed at that to." He sighed and ran his hand down his face. "sergeant Barnes is alive, but he was brained washed and god only knows what they did to him. Hydra turned him into the winter solider somehow. Unfortunately, they would have sent him to kill me. Your mother knows the risk and that they could use her to get to me." He rubbed his soul mark smiling. "I hope you find your soulmate because when you do, they tend to stick with you no matter what. As you know there are three forms of soul marks. The name of your soulmate, there birthdate or a unique shared symbol. Your mother and I had the symbol, as do you. But know I have to tell you something that I'm sure you will hate me for." He wiped the tears away form his eyes and set up straighter. "I cheated on your mother once with Peggy. Which resulted in you having a half-sister." He hid his face for a moment and took a shuddering breath. "her name is Gabriella Hope Carter-Stark." He turned to Peggy Carter as she stood before him and handed him the baby. "you didn't know because its to dangerous for anyone to know about her. Your mother dose but also understand why we couldn't tell you. She has all three soul marks." The baby stared to cry but stopped quickly. "I have seen her mark before. She's part of a triad. She's the soulmate of Steven Grant Rodgers and James Buchanan Barnes." He shook his head and kissed her forehead. Peggy took her and left. Howard spent a good minute just crying. "I'm sorry tony I'm so sorry. That was the last time either Peggy or my self will see her. This recording will be the only record of her. We have set it up so that she will be safe from everyone hopefully. If hydra finds her, they could try to use her like they are using Barnes. I have kept looking for Rodgers because her mark is proof that he is still out there some were. I think the ice has frozen him and his serum is what has kept him alive. Almost like cryogenics. My hope is that one day the two of you will meet and finish what we started with the SSR. As you hopefully now know, Peggy and I are part of the founders of S.H.E.I.L.D. Its my wish that the two of you will take are places and save the world from Hydra. I am so sorry, and I wish I could have told you this in person. Please don't blame Barnes for my death and possibly your mothers. He has no control over himself. Save him if you can." He smirked and smiled "all else fails at least you'll be able to get a look at his arm. I'm still mad that hydra was always had better tech than we did." His smile fell. "I don't know how to say good by to you. I mean your only 10 years old right now. And I know what kind of farther I have been and I'm so sorry I haven't been there for you. I know that one day you'll make ten times better farther than I was. I love you now and forever my son."

Tony was crying as pepper held him. He had a half sister who for all he knew was dead. "I remember when things changed between them when I was 10 and now, I know why. He cheated on my mother with aunt Peggy." He laughs but also picked up the evolve that was hidden in the real. It was a list of latitude and longitude and dates.

"tony what are you going to do?" he stood determined in reading the dates. They were all random and dated form when he was 16 years old to when he would be 75 years old at least. "I'm going to find her in three weeks and in Texas, I think. "Friday start surveillance on Big Bend National park."
