Hi everyone! I know it's been a while. I was originally hoping to get this all finished before Infinity War and Endgame came out but clearly that did not happen haha. So, these chapters are going to disregard a lot of those storylines. Sorry for the hiatus, life has been a lot but we're getting back into this. Thank you to everyone who has stuck with me and thank you for your patience! As a reminder, I do not own anything Marvel.

Her body was so thin Steve was worried he would crush her with a hug but he couldn't help it. He wanted to hold her as tight as he could and never let go. Her arms were tight around his neck and her feet dangled near his knees. He could feel each of her ribs through the sweater had given her from Pepper's closet. Dyed dark brown hair rubbed against his cheek as she buried her face in his neck, the lavender shampoo Natasha used on her filling his nostrils. He closed his eyes, blinking back the tears, but he knew they would come anyway the second he looked at her face again.

"I thought you were dead," she murmured.

"Me? I thought you were dead, for almost a century!" Steve laughed. "Wait, how did…"

"I saw the newspaper. You disappeared, Captain Steve Rogers," she pulled her head back and Steve set her down. He looked at his sister's face closely for the first time. He could see the beginning of her natural sandy blonde hair peeking out at her roots, the scar underneath her eye from when she hit her face on their kitchen table, and her unique eyes: blue with a thick ring of gold around them. The gold seemed to swirl with the edge of blue, at times mixing with it and creating a strange orange colored iris. "All those years, I thought you were gone."

"Technically he was," Tony murmured from behind them. Steve quickly elbowed him in the stomach and was slightly satisfied with the surprised umph he heard.

"Pardon me?"

"It's," he paused, unsure of how to tell his sister about everything he'd been through. He eventually settled for the best explanation he could think of, "A long story, Kate."

"I think I have time," Kate gave a small smile, almost to herself.

"Is anyone else as confused as I am? Raise your hands," Scott called from the island in the kitchen. Steve looked up and saw everyone with their hands up. Kate's face turned red.

"Everyone, I would like you to meet my sister: Kate Rogers," Steve took a small step towards his sister and put a hand on her shoulder. He felt her tense up, and saw the same look of confusion and fear in her eyes that he saw in Bucky's back in DC. He took his hand away, so many questions running through his mind. What could she have experienced with Hydra? How was she still alive? And still this young?

"Since when do you have a sister?" Sam leaned forward on the island, his confusion as apparent as everyone else's.

"I've always had a sister," Steve said slowly, unsure of how to proceed.

"But why didn't you tell anyone? It's not even in any of your biographies," Scott responded.

"Biographies?" Kate met his eyes, almost as equally confused as the others.

"Your brother is the world's first super soldier. Like Bucky, but not as crazy," Sam laughed as Wanda hit him in the soldier. "What? I said he was a friend earlier."

"C'mon Kate. Let's go catch up somewhere quieter." Steve laid his hand gently on his sister's arm and pushed her towards the elevators. She jumped back from his touch, her eyes flashing with fear. Steve dropped his hand and watched her for a moment, realizing that although he wanted to be as close to her as they had been as children, he was going to have to give her space to recover from the trauma she had gone through at Hydra. "Follow me. I'll show you what I've been up to."

Steve gestured toward the elevators which he and Tony had just taken and kept a short distance behind his sister when she started walking. They rode down to the floor below in silence, both staring at the doors in front of them. When the elevator dinged to signal their arrival, Kate stepped aside to let Steve lead the way. He walked down the long hallway with doors lining either side. After a couple minutes they arrived at the one he had been looking for.

"This is my room," he said.

"You…live here?" Kate's confused expression told him what she really wanted to know.

"Sort of. After you disappeared mom and I moved to a smaller house. She couldn't bear to stay in a home which had experienced so much loss. First dad, then you. After the war I was, sort of, forced to relocate from the house we had moved into." Steve didn't know how to explain the "frozen in ice for 70 years" situation to her. How would she understand that a special serum gave him the ability to survive? "Here, let's just go in."

Since he split his time between the compound and his apartment in New York City, although he was unsure what remained of his apartment after becoming a fugitive, there were not a lot of personal belongings in the room he had here. He hoped Tony hadn't touched anything after their fight in Germany, but it was Tony. He would never admit it but Steve knew Tony was sentimental when it came to his loved ones. He knew everything would be exactly as he left it and he was right. Turning on the light he saw his bed perfectly made, a few shirts tossed over the desk chair, and some pictures and news clippings taped to the walls. There was not a lot that would have made it obvious that it was his room and not a spare guest room, but what could he really put up on the walls? Most of his personal belongings were locked away or had been sold after he went into the army. He hadn't really found anything in modern culture that he loved enough to decorate the walls like Wanda or Sam did. Most of his photos were in New York and he preferred to spend his time there rather than the compound.

After taking a quick glance around the room, Steve stepped to the side and gestured for Kate to enter as well. She took a timid step into the room and look around with wide eyes. He could see her look quickly at all the possible exits, windows, air vents, and door, before taking more time to look at the bed and wall decorations.

Kate murmured something to herself, so quite Steve could not pick it up.

"I don't spend much time here so a lot of my personal belongings are back in New York. But it does the job."

"You…have more than one place…to live?"

"It's complicated…" Steve trailed off, not sure how much to actually tell her.

"Complicated…everything is always complicated," Kate sat down on the bed and stared at her brother.

"Well, since we're bringing up things that are complicated, how are you…still so young? You've hardly aged at all."

"I…I don't really know."

"It's okay. We've been apart a long time, I don't expect you to open up to me immediately. Why don't we start by asking simpler questions. Is there anything you want to know from me?" Steve sat down on the bed next to Kate, careful to give her plenty of space. He placed his hand slightly in the space between them, palm up.

After a few minutes of silence Kate answered quietly, "Mom, how did she die?"

Steve sighed, of course she would want to know. Kate and their mother had their differences but they still loved each other in their own way. "Tuberculosis. She caught it one day and couldn't shake it. We buried her right next to dad…and you." Kate looked up at him surprised. "You went missing, after a while the police said we needed to accept the possibility you were never coming back. There was a funeral, we buried you next to dad. It seemed like the only way we could really let you go."

Kate nodded as if in understanding, but Steve could see the tears she was holding back. "And you? The war? You…you were…"

Steve giggle, knowing exactly where she was going with her question. He motioned to the pillows on the bed, "Here, why don't we make ourselves comfortable. This is gonna be a long story."
