YN let out a sigh of relief as she slipped on the leggings and oversized t-shirt. "This. This is what I've missed the most about the twenty-first century."

"Really?" Bucky asked as he lay on the bed and watched YN wiggle into the stretchy pants she so obviously adored. "I, for one, am going to miss the outfits you've been wearing these past few weeks."

YN fixed him with a sultry look as she walked over to the bed and pushed him onto his back before straddling his lap. "Oh, don't worry about that. I plan to hit up the first Victoria's Secret I can find and buy all kinds of lingerie for you to help me out of."

Bucky let out a low growl as he sat up and captured her lips with his. His hands snaked up the back of her loose shirt to explore the soft skin of her back as she used her teeth and tongue to drive him crazy.

They would have probably ripped each other's clothes off before too long, but a knock on the door had them reluctantly breaking away with a sigh.

"Come in," Bucky called out, earning him a glare from YN.

"You didn't lock the door?"

"I didn't think you were going to jump me," he offered as an explanation.

"Am I interrupting?" Steve asked as he peeked his head in the door

"Yes," YN said with a wink.

"No," Bucky answered as he glared at YN.

YN leaned in and gave Bucky one more kiss before she got up off of the bed and started walking toward Steve. "How much do you remember?"

Steve pulled her into a bone crushing hug, and YN took that to mean that he remembered everything. She wrapped her arms around him, but it felt strange to her. Pulling back, she frowned and poked one of his shoulders.

"What?" Steve asked, suddenly concerned.

"You're so big. I miss little Steve."

"He missed you, too," Steve told her as he pulled her back into his arms.

"Yeah?" Bucky asked. "Do you remember both versions?"

Steve held onto YN, but looked at Bucky over her shoulder. "I do. It's so weird. What about you, do you remember both?"

Bucky nodded his head. "It's the serum, isn't it?"

YN stepped out of Steve's embrace and looked between both men. "I remember them both as well."

"Maybe it's because you actually lived through it instead of just being affected by the aftermath," Steve said with a shrug.

YN's demeanor changed in an instant. Her joyful smile faded as anger burned hot in her eyes. "Speaking of which. . ." She stopped speaking to punch him in the shoulder. When she started speaking again, she paused in between each word to punch him. "Why. . .did. . .you. . .wait. . .so. . .long?"

Steve took a step back and began rubbing his shoulder. "Ow."

"Oh, I'm sorry, was that uncomfortable? You know what else is uncomfortable? Try thinking that you're going to be stranded eighty years in the past because your buffoon of a best friend can't take a simple hint."

Steve hung his head in shame and grimaced. "I'm sorry?"

Her anger left as quickly as it had come and she let out a sigh when she saw his pitiful expression. "Steven Grant Rogers, you're insufferable." She stepped closer to him and framed his face in her hands. "But why?"

He leaned in and gave her a kiss on the forehead. "That's not my story to tell."

She tilted her head as she considered his words. If it wasn't his story, then who's was it?

"I think it's time I told you the truth, doll," Bucky said, drawing her attention away from Steve and back to him.

"What are you talking about, Bucky?" she asked as her breath caught in her throat.

"I can leave if you want to do this alone," Steve said.

"No," Bucky told as he gestured to a chair across the room. "Stay. I might need you to help me explain this."

Bucky reached for YN's hand and drew her back to the bed with him. She curled her legs up under her as she sat facing him with a look of worry on her face. He ran a hand through his hair as he tried to figure out where to start.

"Okay," he said as he let out a deep breath. "You know that Shuri and Wanda helped remove the trigger words and restore the memories that I'd lost over the years."

"Yes," YN said as she nodded her head. "You told me all about Wanda risking her life to help you and how angry Shuri was that you'd refused her initial offer."

Bucky let out a deep sigh. "There's something I didn't tell you about."

YN saw the look on Bucky's face and she knew she probably wasn't going to like what he was about to say next. "Tell me now."

"White people are idiots," Shuri muttered under her breath as she shook her head in frustration. "Captain, bring me your friend right away."

Steve looked from Wanda to Bucky and then back at Shuri in confusion.

"Her," Shuri said, pointing to Wanda's nearly unconscious form on the table.

Steve scooped Wanda up and walked over to lay her down on a table that Shuri indicated. "What are you going to do?"

"First of all, I'm going to ease her pain," Shuri explained as she began tapping icons on the monitor beside the bed. "Then I'm going to make sure she didn't do any damage to her mind and fix it if she did."

"You can do that?"

Shuri pursed her lips and shook her head again. "If you had allowed me to fix Sergeant Barnes' mind to begin with, I wouldn't have to."

Steve let out a sigh as he looked down at Wanda. "She wanted to help – trying to atone for some of the choices she's made in the past."

"By dying?"

"Wanda knows her own limits. Don't underestimate her."

Shuri turned back to the screen and her eyes widened when she saw the brain scans. "I've never seen anything like this before. How did you say she got her abilities?"

"Thor calls them Infinity Stones," Steve explained. "HYDRA got their hands on the Mind Stone and used it to alter Wanda's, and her twin brother's, genetic makeup to give them their powers."

"Fascinating," Shuri said as she continued studying the scans. Once she was sure that Wanda would suffer no ill effects from her journey into Bucky's mind, she had Steve move her and help Bucky transfer to the other table.

"How are you feeling, Sergeant Barnes?" Shuri asked once Bucky had taken a seat on the table.

"Bucky," he corrected before he lifted his legs and lay flat on the table.

"Very well. How are you feeling, Bucky?"

"Good."

"I'm going to run a few scans to make sure that Ms. Maximoff didn't miss anything. The brain is tricky sometimes and likes to hide its secrets well."

"Do what you gotta," Bucky said as he closed his eyes and braced himself for the pain.

Shuri laid a hand on his arm. "This will cause you no pain. Those days are over, at least in my lab."

Bucky smiled and relaxed as best he could.

"What do you see?" Steve asked as he looked over Shuri's shoulder.

"There's something here," she told him as she pointed to a section of the brain scan that was darker than the rest. "I'm not sure what it is."

"Do you think it's wise to go poking around in his brain if you're not sure what you'll find?"

She took a deep breath and swiveled around to meet his gaze. "If HYDRA has any more surprises left, I'd say it's best to uncover them now rather than later."

Steve shrugged and let out a sigh. "Good point."

She turned back to the monitor and began tapping the screen again. Steve watched in awe as a beam of light from above the exam table centered on Bucky's forehead. Shuri glanced from the monitor to Bucky and back to the monitor again.

"Just a few more seconds," she said as the scan showed the darker section starting to lighten.

Bucky let out a gasp as his eyes flew open. Shuri quickly shut down the device and jumped to her feet as she rushed to Bucky's side.

"Are you okay?" she asked. "Are you in pain?"

"No," Bucky said as he shook his head. "It's just more memories coming to the surface."

"Memories of what, Buck?" Steve asked.

Shuri helped him sit up so that his legs were dangling off the side of the table. He gave her a weak smile and squeezed her hand before turning back to Steve.

"Memories of YN," Bucky finally answered with a confused look on his face.

Steve's brow furrowed. "I don't understand. You only met YN a few days ago in Germany. Or did you meet her on a mission as the Soldier that you'd forgotten about."

Bucky let out a long breath as he tried to wrap his head around what he was about to say. "No, not as the Soldier. I remember her from 1942."

YN got up off of the bed and began pacing the length of the small room before turning around and giving Bucky a long look. "Let me get this straight. Shuri – King T'Challa's little sister – accidentally unlocked your memories of me from 1942. . .before we travelled back in time."

Bucky looked to Steve for help.

"I was there, YN," Steve said as he got up and moved to stand in front of her. Reaching down, he grabbed her hands. "I didn't understand it at first, either, but now it all makes sense."

She let go of Steve's hands and moved to sit on the bed with Bucky again. "How was that possible?"

"I don't know," Bucky admitted. "All I know is that after she did whatever she did, I had all these memories of our time together in 1942."

"Why didn't you tell me?" she asked as her eyes pleaded with him to help her understand.

"And what would you have said if I had told you that we had previously met in 1942 and fell in love?"

"Okay, fine. I would've thought you were crazy. But that doesn't explain why you didn't tell me that Steve would show up the morning after the Expo to take us home. I can't believe you kept that from me for weeks when you knew I thought he was dead."

Steve's eyes grew round with shock. "You thought I was dead?"

She gave Steve a sorrowful look. "Yeah. It was the only logical explanation for why you hadn't come back for us yet. Well, either that, or you were the biggest idiot in the world and couldn't take a hint."

"I wasn't sure Steve was coming back for us," Bucky said, drawing YN's attention back to him.

"What do you mean? You just said Shuri unlocked those memories two years ago."

"She unlocked the memories I had from 1942 – the version of me that you met there," he explained. "I had no memories of the two of us going back in time. Don't ask me why, but for some reason the universe only saw fit to give me one side of the story."

YN took another breath and looked up at the ceiling to collect her thoughts. "Okay, let me see if I understand. You remembered meeting me at the Three Deuces. . .?"

"That was my first memory of you," Bucky said with a wistful smile. "God, you were so beautiful that night. And so feisty." He reached over and brushed a hand down her cheek. "I think I fell in love with you that night as you were yelling at me on the dance floor."

She let out a soft chuckle as she remembered the night in question. "You were so cocky. I had to put you in your place."

"But you let me kiss you," he reminded her.

"And then I went back to Howard's and I let you. . ."

"Okay, that's enough for me," Steve said as he jumped to his feet and started for the door. "I think you can handle it from here, Buck."

"Sit back down, Rogers," YN ordered as she pointed to the chair he'd just vacated. "You're an adult, you can handle it."

Steve sighed and returned to his seat. "Can you please refrain from going into too much detail, though?"

Bucky laughed as he shook his head. "Sure thing, pal." He turned back to YN. "Where were we? Oh, right, that first night. I'll fully admit, I was terrified that night."

"Why?" she asked. "You already knew I was going to fall in love with you. What were you scared of?"

He reached out and took her hands. "I was scared you were only in love with him."

"Not this again," she said as she rolled her eyes. "You and him are the same person, Bucky."

"I know that now," Bucky said with a huff. "But you have to remember that I only had one set of memories to go off of. I only knew how you felt about the 1942 version of me."

"And yet you let me go out every night not knowing if I'd only fall in love with the younger version of you."

"Yeah," he said. "I was praying that as you fell in love with him, you'd somehow find it in your heart to love me as well."

"I fell in love with you first," she reminded him.

"I had no way of knowing that at the time, though."

YN took a deep breath as she tried to imagine what Bucky must have been going through while they were stuck back in time. He'd not only had to deal with his guilt concerning Howard, but he also had the stress of not knowing if she would ever love him the way he was in the present, or if she'd only loved the man he used to be.

"I'm curious," she said after a few moments. "Once Shuri unlocked those memories, did you think I'd somehow traveled back in time, or did you think I was reincarnated, or what?"

Bucky looked at Steve and they both began to shake their heads. "Neither one of us had a logical explanation. We went over all the different possibilities, but since Steve didn't have those memories yet, we decided it must be some type of brain damage from when HYDRA used to wipe my mind."

A sad look came over YN's face. "And you had to live with that thought for two years."

"Finding out the truth behind those memories made the trip back in time worth it all."

She leaned in and kissed him. For a moment, they forgot about Steve until he began loudly clearing his throat to remind them that they weren't alone.

"Sorry," YN said with an apologetic shrug.

"It's good to see you two like this," Steve said with a smile. "It reminds me of the old days when the three of us would hit the town."

"I still can't believe you had all those memories of our time together and you never said anything." YN gave Bucky a long look before her expression slowly morphed into one of surprise. "Wait a second. Prague. And the plane. That's why you were staring at me, wasn't it?"

Bucky let out a relieved breath. "It's so good to finally tell you the truth. Those first few days I spent with you were absolute torture. I had all these memories of dancing with you and kissing you – spending that night lying in bed and talking until we both fell asleep. I thought none of it was real, but then seeing you again. . ."

"That's why you were acting the way you were once we got back to the compound," she mused aloud. "I couldn't figure out why you were acting so possessive in front of Tony."

Bucky's eyes grew hard. "It just about killed me to see the way you looked at him."

"And that's why you couldn't stand Howard at first," she added with a laugh.

"The apple doesn't fall too far from the tree, huh?" Steve asked with a smile. "I take it Howard hit on you?"

"Oh yeah," YN said as she started to laugh. "Especially once he thought I was a super soldier."

"Why did he think that?"

"We may have led him to believe that the program produced more than just one," Bucky admitted with a grin. "It ensured that he'd let us stay with him until you came back for us."

Steve snapped his fingers excitedly. "Avengers Tower. Tony built the tower in the same spot that Howard had his house in the forties."

"He was a huge help to us," YN told Steve. "I don't know how we would've survived if it hadn't been for Howard, Jarvis, and Ana."

"I'm sorry you had to go through that, guys," Steve said with a sad look on his face. "Like Bucky, I only knew one half of the story, so I thought I needed to wait until the day we both left New York to come back for you two. I wanted to make sure you had enough time to fall in love."

"Admit it, Rogers," YN teased. "You just wanted to spend those last few weeks hanging out with me so you'd have someone to watch your back in those alleys."

"Just how many fights did you two get into?" Bucky asked with a laugh.

YN and Steve shared a conspiratorial look. With a laugh, YN answered, "More than we told either version of you."

"I have an admission to make," Steve said with a bashful look toward YN.

"What?"

"I saw you use magic that day."

"You did? Why didn't you say something?"

"I didn't know what to say, but I was scared that if I told you that I'd seen what you could do, you'd disappear on me."

"Okay, I still have one question that needs answered," YN said as she gave Steve a look. "How did you know to come to the apartment that morning and not Howard's?"

Steve let out a breath. "I spent a good hour weighing my options before Strange and I attempted the portal. The last memory I had of you was walking away with Bucky at the Expo. I figured you'd want to spend as much time with him as you could, and the only place that would afford you the privacy you wanted was the apartment." Steve paused and looked at Bucky. "I remember how hard Bucky took it when he asked Howard about you during the war and Howard told him that he hadn't seen you since the Expo. I figured you wouldn't have taken Bucky leaving for the war all that well, and I guess I was hoping that this idiot would realize that as well and go to you instead of making you find your way back to Manhattan on your own."

YN shook her head. "None of this seems real, you know? I mean, how is any of this possible?"

"The only thing I can figure out is that it was meant to be," Bucky said.

"Like fate?" YN asked.

"Yeah, something like that," Bucky agreed. "I mean, how else could Shuri have unlocked those memories if we weren't meant to go back in time?"

YN looked from Bucky to Steve. "So, what happens now?"

Bucky shrugged his shoulders and looked to Steve for an answer.

"Tony is pretty sure the amendments to the Accords will go through and then we can all come out of hiding for good," Steve told them. "If it doesn't, I'd like for us to stay together from here on out."

YN and Bucky shared a look before YN turned back to Steve. "Nat will be invited as well, right?"

Steve's face took on a slightly pink hue as he began to rub the back of his neck. "Sure. I mean, the two of you are pretty close, right?"

"Just admit that you have a crush on Romanoff," Bucky said with an exasperated sigh. "Didn't you learn anything with Peggy?"

"I've been a little busy the past couple of years trying not to get arrested," Steve said with an angry look on his face. "What have you been doing, you jerk? Oh, that's right, you've been hiding out in Wakanda playing with your goats and brooding over YN."

"Wait a second," YN said as she raised a finger in the air. "No one told me anything about goats."

Bucky waited until YN was asleep before quietly getting out of bed. They'd both had an emotional day and while she'd passed out almost immediately after Steve had left, Bucky couldn't get his mind to shut down.
