Sebastian Stan/Bucky Barnes - He's Real

You went to slam the door, but that same metal arm reached out and stopped you. You turned back around in fear before walking backwards and hitting the wall behind you.

"I need your help," his deep, gravelly voice spoke. The fear in your eyes only grew.

"Sebastian!" You called out desperately. You heard Sebastian immediately shooting up from his place on the couch, and he was soon rushing over to the scene.

"(Y/N), are you-" he began, but he cut himself off as he laid eyes on the man standing in the entry way to your home. "Wh-what? But... But that's... Not possible..." He whispered. Sebastian grabbed you and pushed you behind him, keeping his hands on your hips in case he needed to move you again to keep you out of harm's way.

"Sebastian Stan," Bucky acknowledged your boyfriend with a casual nod of his head. "I need your help. Please," he continued, his voice desperate. You could see his chest heaving as you looked out from behind Sebastian. Bucky's head turned every once in a while to check behind him.

"Help you? I don't even know how this is possible! You look exactly like me!" Sebastian shouted with a dangerous edge in his voice. Bucky huffed in annoyance.

"My name is Bucky Barnes, you know exactly who I am-"

"No, Bucky isn't real! Who are you?" Sebastian questioned, his grip on you tightening. You reached out and pressed your hands against his back, trying to calm him down. It must have worked, because his grip loosened once more.

"Listen, I'll explain everything if you just let me inside, alright? I'm not going to hurt you as long as you don't try to hurt me," the metal armed man reasoned. Sebastian hesitated.

"Sebastian," you whispered. He turned his head to look at you. You nodded, causing him to sigh.

"Alright, fine. But if you try anything, I can take you down," Sebastian muttered. Bucky chuckled and nodded, walking in.

"I'm sure you can," Bucky replied as if speaking to a child. You couldn't help but let out a small laugh at his comment. You all made your way into the living room again. You and Sebastian sat down on one couch, while Bucky sat down on the one across from you. You took a moment to completely take in his looks.

He did, in fact, look exactly like Sebastian when he was in his costume. His eyes were the same shade of blue, he had the same stubble, his hair was the same length, his arm looked the same, he had the same weapons, and he was the same build. It was actually quite terrifying, if you were being honest.

It was about now that you realized the intense staring match going on between Sebastian and Bucky, so you decided to step in before one of them started attacking the other. You cleared your throat. "So, you said you would explain everything?" You prompted, snapping the two men back into reality.

"Yes, I did. So, you know all about my life. You know what happened with HYDRA and everything, and you know all about the feud that went on between Tony and Steve." You and Sebastian both nodded. "Well, not too long after I went into the cryo freeze, I was brought back out. T'Challa's men had made me a new arm, which is the one I have now. I was wanting to go back into cryo, but that's when things got... Weird. This yellow and red streak raced into the building, and when it stopped we realized it was a man. He looked around like he was terrified, and of course, he should have been. Everyone was ready to fight him in case he attacked us, but instead he started asking us for help. He said that he had come to the wrong universe and that he had to get back home to stop another 'speedster' as he called them. We asked him how he got there and he told us that there was a singularity that opened portals to other universes, and he had tried to recreate one to bring him to a specific Earth, but it brought him to my world. We tried to help him, but when HYDRA found me again, they ran me straight into one of the portals we had made with one of their own speedster agents. That portal led here, to this Earth. Now HYDRA agents are here, and they're looking for me. I need your help to get them and myself back through the portal."

Both you and Sebastian just sat there in confusion as his explanation. Finally, you turned to Sebastian to whisper, "Did he just explain season two of The Flash?"

Sebastian raised an eyebrow at you before looking back at Bucky. "Let's say we believe you-"

"Which we should because you literally have Sebastian's face, and that's kinda hard to just kinda... Do," you interrupted.

"-then why did you come to us? You could've gone to any scientist and they would do you so much more good. Why us?" Sebastian asked. Bucky sighed.

"You're the only people I can trust, because you're the only people that will believe me. There's a good chance you won't tell anyone or send me off to HYDRA again because from what I've heard, you guys actually care about me, or at least you care about my character in your movies. Now, since your movie career is based off of me actually living in my universe, then I believe you would be pretty desperate to get me back there so you can continue to be successful, correct?"

Slowly, Sebastian nodded. "I can't imagine what the fans would say if Bucky just disappeared..." He whispered. You nodded in agreement. "God, this is so weird... I'm talking to my character..."

Bucky huffed in amusement. "You think it's weird for you? I'm talking to the guy that acts like he's me for months at a time. I don't even exist in this universe. Now that  is a weird feeling."

You chuckled and looked down at your hands before looking back up at Bucky, who seemed to be staring at you a bit, his head tilted ever so slightly.

Sebastian noticed this as well and began to clear his throat, sending a glare in Bucky's direction. "Hey, do you mind not staring creepily at my partner, though?" He suggested in annoyance, wrapping an arm around your waist and pulling you closer to him.

Bucky shook his head to clear his thoughts. "Sorry, it's been a long couple of days."

"What can we do to help you, Bucky?" You asked in concern. Sure, he might not exist in your universe, but he existed. You cared about whether he was okay, and the fact that he had your boyfriend's face probably contributed to that a bit.

"I need to get back through the portal, the same one I came in through. That's the only way I can know that I'm getting back to the right place. It's too risky to make a new one. Plus, making a new portal is just ripping another hole in time and space, and that puts every universe in danger. It's not going to be easy, though. It'll definitely be risky. HYDRA will be tailing our every move. They'll try to stay three steps ahead of us at all times, and they'll ambush us at every possible point. I can't promise that you'll make it out alive," Bucky explained. You stayed silent as he began to speak once more. "I understand if you don't want to help. I know that it's a big thing to just drop everything and help someone you don't even know. I just had to try."

Sebastian chuckled. "Bucky, I probably know you more than you think I do. I know all about your life. I know everything there is to know about you. I have to put myself in your mind and in your place for months at a time. I feel what you feel and I see what you see. You're not a stranger to me, and you're not a stranger to (Y/N) either." You nod in agreement, and a small smile makes its way onto Bucky's face.

"So that means..."

You and Sebastian both smile and nod. "We're in."

Okay so that was completely nonsensical blabbering about how he got there but I kind of wanted to use The Flash for some reason, so bam. I made some crap up, yes, I know it makes no sense. Welcome to my mind.

Stay street, stay unlit, stay alive.
