Dr. Tony Stark, please report to Sector 3 for briefing. The announcement echoed.
"Can't a man enjoy some free time for once? This is the the last time I want to get interrupted during my 2 HOURS A DAY lunch break!" Stark said in an annoyed tone. "Yinseng, get me the labcoat and a lunch pack!"
"Why?"
"BECAUSE I TOLD YOU TO, and you definitely do not want another employee misconduct report on your file, or am I hearing that wrong? "
"All right you made your point. Here you go."
"Remember, when I come back, I want a fresh American cheeseburger WITH fries delivered to my office. The keyword is FRESH, not one of those melted burgers I got the last time."
"No problem, DOC-TOR." Yinseng said, grinding his teeth.
Stark heads for Sector 3. He is then escorted to a room where Dr. Selvig is waiting.
"Where were you Stark?" Selvig asks impatiently. "Actually forget it, we don't have time to argue. This is MTF Omicron-6 , the "Howling Commandos". This is the Team Leader, you will brief him on the anomaly."
"Which one? We already had like, 9 anomalies this week."
"That building on Bleecker Street in New York, the one you researched on."
"Oh that one. Thanks. And by the way, what's the point of Level-5 Clearance if I can't get the name of a Team Leader? What should I call him, Michael Corleone?"
"He is Team Leader Steve Rogers, but you will refer to him as Cap. Now stop being annoying and brief him already."
"Happy to see you too Selvig."
Stark grabs a file from the desk and goes to Cap.
"Hello Dr. Stark. I have heard about you. Your reputation precedes."
"Thanks, and hello to you too Ste- I mean Cap. I am Dr. Tony Stark, and I will brief you on the anomaly. The building's exact address is 177A, and currently the only safe entrance is from the front. You must enter in your public disguises, and your equipment must only be used when the building is confirmed to be empty of civilians. Evacuate and use amnestics if civilians are found on the property. Our special agents have reported no hostile encounters, only space-time gateways. Set your loadout to these specifications, and we should have no problem containing this anomaly. Remember to always keep your communications system ON so we can detail you along the way. Roger that Mr. Rogers?"
"Roger that. All right team, Let's move out!"
MTF Omicron-6 arrives at 177A Bleecker Street in civilian clothing. It is midnight. After checking the surrounding areas for civilians, they proceed to the entrance of the building.
"Steve, you sure we don't need guns for this extraction?" Agent Barnes asked.
"Don't worry Buck. It's just another mission in the book."
"You sure about that Rogers?" Agent Carter replied.
"I told you it is nothing out of the ordinary."
"Our standards for 'ordinary' are much more widespread than you think Rogers."
"She's right Steve."
"Stop being paranoid. It will be fine. A simple Secure and Contain mission. Easy as that."
Steve opens the main entrance door. He is surprised to see it unlocked. He and the MTF team proceed to enter the building and search for civilians.
"Team, split up. Barnes, Carter and me will check the upper areas, while you check the lower areas. Maintain radio contact. Out."
Agent Rogers, Carter and Barnes proceed to the upper section, while the other agents investigate the lower areas.
"So, Steve, how much do we know about this place?" Barnes asked.
"What we do know is that there is some teleporation device here. We need to confirm its existence and extract it."
"I didn't know Harry Potter went here."
"Who's that?"
"The most well known wizard of all time, I think? You need to brush up on your pop culture Steve."
"I hear that a lot. What about you Carter, how much do you know about this Harry Potter stuff?"
"As much as I know you. You cannot say you even haven't heard of it, ever."
"This is strange then. You two know about all of this pop culture stuff while I don't? I am not that older than you people."
"Hehe, Old Man Steve sounds pretty catchy I think. Or does Old Man Cap sound better?" Carter said sarcastically.
"That is the best name I have ever heard." Barnes replied. They both started laughing.
"All right, quit it you two."
Through the radio "Cap, lower area clear, going to get the equipment. Radio silence for 15 minutes. Out."
"I guess I better go help them. That research mumbo-jumbo stuff is pretty tricky to handle. Barnes come with me, guard the entrance. Steve, stay here. Keep an eye out. Me and Barnes will be radio silent for 15 minutes."
"Hey I thought I was the Team Leader." Steve said.
"Bwah-Bwah, little baby Stevie scared of being alone for a few minutes?" Barnes said sarcastically.
"No.. well.. what choice do we have. Go on. Will rendezvous here in 15 minutes. Before going radio silent do a check first." Steve replied.
"Relax Steve. Nothing out of the ordinary, remember?"
"Ha ha ha. Very funny."
A minute after Barnes and Carter leave, through the radio "Hello hello, 1, 2, 3, mike check. You hearing me?"
"Yeah, loud and clear."
"Good. Woah woah be careful, that shit is expensive. Our budget is low as it is."
"Language, Barnes."
"Seriously Steve, you are definitely old."
"Sorry, just had an impulse."
"Yeah most old men have that. Radio silence in 3, 2, 1. Out."
Steve wanders around. He waits for radio contact.
Suddenly, he hears something.
A sound.
Steve turns around, to reveal that there is a man, in blue and red robes, wearing a glowing necklace. Steve, confused and shocked, takes out his knife.
"Whoever you are, stay away, or else I will be using lethal force. Stay back."
"Steve, listen to me. I am from the future. Your memories are not real. This is not who you truly are. Relax, and listen to me. Just hear-"
"What? How do you know my name? Are you mind-reading me? Tell me, are you a telepathic entity? Why are you trying to fool me?"
"Steve, I am sorry I have to do this."
The man disappears through a portal.
"What? What just happened? Grabbing the radio Team, I think we found your Harry Po-"
The man comes out from behind and suddenly grasps Steve's forehead. "Open your eyes Steve. Open your mind!"
Steve goes into a trance. All of his memories from his actual reality come back to him. His tragic past, the friends he lost, and everything he had to sacrifice.
The man then removes, the hand from Steve's forehead. Steve drops from the trance onto the floor. He is sweating profusely. His mind is torn. He doesn't know what he believes. The only thoughts of his mind are those of his past.
"What is happening?"
Breathing heavily
"Bucky is dead."
Breathing heavily
"Everyone is dead."
Breathing heavily
"Half of the univ-"
Breathing heavily
"Half of the universe, is dead."
Breathing heavily
"We failed."
Breathing heavily
"We lost."
Breathing heavily
"Oh no."
Breathing heavily
"Am I real?"
Breathing heavily
"Is this world real?"
Breathing heavily
"Did anything I believed here, was real?"
Breathing heavily
"Oh God."
Breathing heavily
"Please let it be real."
Breathing heavily
"Please let Bucky be real."
Breathing heavily
"Please let Peggy be real."
Breathing heavily
"Please let me be real."
Breathing heavily
"Don't let him be real."
Breathing heavily
"Don't let Thanos, be real."
Steve, had his mind torn apart. He had lived two lives, but he didn't know which one to believe.
"Who are you?" Steve asked, still finding it hard to breathe.
"My name is Doctor Stephen Strange, I am from the future. Whatever you believe here, this whole world you live in, is an illusion. Thanos, has trapped you in this illusion. Your minds, memories of this place, anything here, is not real. He did this, so you won't try to come after him."
"Is the actual reality still the same?"
"Yes, unfortunately. Half of the whole universe does not exist anymore."
"Do we have a chance? Is there anything we can still do?"
"Yes. That is why I am here. I also died with half the universe."
"Then how can I see you? Are you real?"
"Yes, yes, I am very real. I am from the future. In the future, you undone what Thanos did. You, and the Avengers combined."
"How did we do it?"
"That is something you must learn for yourself."
"I need to know what I need to do from now on. I will be trapped forever here!"
"Remember, Tony Stark is the key. Protect him. Give him this artifact."
Strange hands over an amulet to Steve.
"What will this do?"
"It will restore his memories, and inspire him where to go, and what to do. I will do the rest."
"Thank you."
"No, thank you. I am here today because of you. You will save us all. May we meet again, one day."
"We hopefully will."
Strange leaves, through a portal.
Suddenly the radio comes on.
"Steve? Steve? Are you there?"
"Yeah I am here. Over"
"Phew. Thought we lost you there for a second. Over"
"Its nothing, I just forgot to push the button to talk, over."
"Well we are coming up to the rendezvous point, meet us there. We didn't find anything particularly interesting here, just some cool stuff. I don't think this deserves to be called an anomaly, over."
"Yeah you are right. Pack up the equipment and head out. No need to come up here. I will meet you at the entrance. Over."
"All righty then. Over."
Steve, walks to the entrance. Conflicted. Half of the Universe is dead. It doesn't matter which life he believed in, but if he wanted to believe it. This life is peaceful, Bucky is alive, Peggy is alive, everyone is alive, like they should be. The Foundation protect this world. There is nothing to worry about.
"Wait."
"No."
"This life isn't real."
"But it looks so real."
"I want to be here."
"But I cannot."
"But Bucky is alive here."
"No he is not."
"If I don't go, maybe he will stay alive here?"
"But I can bring him back. Really bring him back."
"If I could do that, would I take the chance?"
"Yes I would."
"This life isn't real."
"Bucky isn't real."
"Peggy isn't real."
"Only Thanos is real."
"Only my other life is real."
"Only I am real."
Steve, now awake of what he truly is, and what his responsibility is, is ready to face Thanos.
But he cannot do it alone.
"Hey Steve, you all right?" Barnes asked.
Steve looked at Barnes. He knew his best friend is an illusion.
"Yeah Steve, you look pretty shaken up."
Steve looked at Carter. He knew his love interest is an illusion.
"Team Leader, do you feel alright?"
Steve looked at his whole team. He knew that the people he had been doing missions with for as long as he can remember, didn't exist. They were illusions.
Steve replied
"Yeah, I am fine. Just feeling a little sick, that's all. Lets go, we need to be there for debriefing."
"All right Steve, Whatever you say."
At the Foundation Site
Team Leader Omicron-6, please report to Sector 3 for debriefing. The announcement echoed.
Steve walked the corridors.
He arrived at the room.
Dr. Selvig was waiting.
"Hello, Cap. This will just be a quick debriefing of your observations of the building you searched."
"Ask."
"Are you absolutely sure you found no traces of any anomalous activity in the area?"
"Yes, I am sure."
"What about the data Dr. Stark gave you?"
"I think it was probably faulty information from the special agents. It can happen from time to time, you never know."
"So if we were to send another MTF unit for investigation, we wouldn't find anything of suspicion there?"
"Don't know why you would want to do that, it would be a complete waste of manpower, but if you sent another team you would get the same results."
"All right then. Thank you Cap."
"Hey, Dr..?
"Erik. Erik Selvig."
"Dr. Selvig, can I personally meet Mr. Stark please?"
"Yes, of course. Let me lead you to his office. Be careful however when you talk to him, he has a very fragile ego."
"I'll be sure to keep that in mind Doctor."
Steve is escorted by Selvig to Tony's office. They arrive at the door.
"Well I will leave you to it then. If you finish talking, report to the guard down the hall. He will lead you to wherever you wish to go around the site."
"No problem. Thank you Dr. Selvig."
Tony's Office
Steve knocks on the door.
Muffled voice "Who is it?"
"This is the Team Leader Omicron-6. I wished to talk to you personally."
Tony opens the door.
"Yeah this is the second time today I met you. Coincidentally, this is the second time my lunch has been interrupted. I wonder if they correlate?"
"I am sorry Doctor. I just wanted to hand you over this artifact I found on the site."
"Oh a souvenir! I hardly get them these days. But then, the number of days I get a holiday each year is pretty limited too, so thanks, I guess."
"Yeah, I just wanted you to take it. Close the door, don't want anyone seeing me giving you this."
"Yeah you're right." Tony closes the door.
"Here you go."
Tony takes the artifact. As soon as he touches it, he goes into a trance. His memories, the true memories, come back to him. But his mind becomes shattered. This time however, Steve is here to guide him.
"What is happening?"
Breathing heavily
"Peter is dead."
Breathing heavily
"Everyone is dead."
Breathing heavily
"I failed."
Breathing heavily
"I lost."
Breathing heavily
"No, Tony, we didn't lose. We just hit a setback."
Tony looks up and sees Steve's face.
"Steve?" Tony says, with tears in his eyes.
"Hey Tony. It has been a long time." Steve replies, with watery eyes.
