Sherlock meets the Avengers- A crossing of fandoms

Revealing the story

A/N: I just watched the new season of sherlock (or, what's on Netflix) you should go watch it before you read this. May be spoilers!!!!! (Read the rest of the A/N if youve seen the season or dont care about spoilers) I will change the story a little though. John will not have been there and Mary is alive, their child unborn. Ok, to the story, hope you enjoy.

Sherlock, John, and Tony once again set off for England. They only took the team of three to avoid looseing time. The three seemed to be a good team. They landed in a small field near the dock. Sherlock made sure to bring a couple guns and his harpoon.
"Here it is. This seemed way to easy. Watch out for traps." Sherlock stated, pointing to the now recognizably run-down warehouse. What was with this guy and warehouses?
"Aren't traps far from his style?" John asked, haveing never heard of Moriarty useing traps.
"I have the feeling that might have changed." Sherlock gulped, pulling out his gun. Tony had his suit on and was ready to fight if he had to. Everyone stopped at the door, took a good look and scanned for traps before slowly opening the door, jumping out of the way just in case. Nothing. Sherlock made sure there were no trip wires before entering. The building was just one big room, nothing inside other than pillars supporting the roof, and an office. There was nowhere for traps. This was to easy. The door to the office was also trap free. The trap was mental. The trap was a picture and a note. An obligation. On the wall, one note was taped to the wall, hide inside an envelope with a picture of her. The note read as follows; sherlock, I gave you a dead trail for a reason. I want you to go through your past. I want to force you to show your colors to the world. Use your family resources, this is a family matter.

"Sherlock, are you ok?" John asked, seeing how sherlock gulped.
"We have to involve my sibling.... siblings." Sherlock hesitated.
"Siblings? Sherlock, you have one sibling." John stated, confused.
"Ya, I searched you up when I found out you would be comeing. You have one brother. Mycroft, right?" Tony stated, very confused.
"I used to have three siblings. Your about to meet the two that live." Sherlock stated grimly, takeing out his phone and calling his brother.
"Yes, brother dearest? This must be important." Mycroft spoke through get phone.
"Moriarty is back and he has gone to far." Sherlock stated.
"How so?"
"He has kidnapped mother and father. He was controlling loki since he first came to earth. And... and he is forcing me to get you involved, and... let's just say the east wind is comeing. Moriarty wants me to go down 'memory lane' that means Eurus must be brought into this. We have to speak to our sister." Sherlock gulped, remembering what happened the last time anyone tried to get help from his sister.
"What!? Just... what? Do you remember what happened last time, Sherlock? Do you remember what she did to Victor!? She is in the equivalent to hell and even shield doesn't even know she, or where she is, exists. And you want to get help from her!? Even after what she did to us!?"
"I know! But mother and father will probubly die if we don't do this. Along with some poor man caught up in the middle. Moriarty gave this to me as the case I have to solve before a man blows up, just like last time. Remember how a man shot himself because you couldn't,  and how that got his wife killed as well? Remember how I was ready to shoot myself instead of shooting you? Do you remember that? We had to be soldiers that day. I had to be a soldier, force myself through not only suddenly haveing a sister that I thought drowned our dog, to finding out that he dog she drowned was acctualy a brother that I managed to forget!? I'm human, ok! This hasn't been easy. And I am asking on behalf of our parents, as your little brother, to do this. We have to be soldiers again, Mycroft. I pulled through when even you couldn't. So listen to me. This, all of this, is my fault, because I always have to be the hero. I almost had to shoot you, we lost Victor, because we wern't there for our sister. So listen to me and be a soldier. I will not loose our parents as well , not like this." Sherlock stated firmly, choking on the last three words.
"Ok. Ok. I'll pick you up in a helicopter in a few muinets. Explain to your friends. Where are you?" Mycroft stated, just a hint of emotion in his voice.
"Thankyou. We're are the docks west of our old childhood home, the burned one. Hurry." Sherlock gulped, regaining his composer.
"I will. Be ready." Mycroft stated solomly before hanging up.
"You have some explaining to do, and from that phone call, alot of it, it seems." John stated seriously.
"I suppose I better get started then, shall I?" Sherlock sighed.
"Agreed." Tony stated.
"Ok... so, I never knew this, for as a child I rewrote what happened, covering up the trauma. But I had a sister, Eurus, and another brother, Victor. We would always play pirates, I was yellow beard and Victor was red beard. But Eurus wanted to play with us as well. Victor and I were thick as thieves, we would never leave eachother alone. Eurus was three times as clever as Mycroft. A case that would take me a week to solve now, would now only take her muinets. She drowned Victor in a well. She wouldn't tell us where he was. She only sang a song, told us that the answer was in the song. We never found him. She then burned down the house. She was locked up in a place that not even shield knows was built, way out in the middle of the ocean. To cover up the trauma, I rewrote everything. My father is allergic to dogs, so for some reason I made Victor, red beard, in my head, a dog. My dog red beard. And then I completely erased Eurus. I wanted to see my sister, as I only found out about Victor later on. She had power over everyone in that hell hole. She blew up the flat with Mycroft and I still inside. She kidnaped Mycroft and I and put us through a series of tests. The governor was there to. It was either Mycroft shoots the governor and his wife lives, or his wife dies. Mycroft couldn't do it. The governor shot himself. We only did this because a little girl on a plane would die if we didn't get through these challenges. I had to solve a case and it ended up killing three brothers when only one was guilty. I had to get Molly to say that she loved me or her entire flat would blow up. And then I was supposed to kill Mycroft. I wouldn't do it. I couldn't. I put the gun under my chin and started counting down from ten. She knocked us out before I could though. She brought us to the home she burned down, forcing me to solve the red beard case before Mycroft died the same way. The little girl on the plane was her. She was so far in the sky, so much starter than everyone else, that she couldn't get safely back to the ground. Before that whole experience, Mycroft would oftin get help from her, and in turn, give her a treat as a Christmas present. One year, her present was five muinets of unsupervised convorsation with Moriarty. That's all it took. It only took five muinets for her to almost make me kill my only living brother. She is trying to get better. But I have to play the violin with her every time I visit if she is going to try. She won't even talk if I don't. That's about everything. I won't be explaining it again. You want any of the avengers to know, just tell them yourself. But shield must never know of this place. My sister can never be known of by shield."Sherlock explained, takeing up most of the time before the helicopter arrived. The two men stood there shocked wile sherlock walked over to his brother, calmly holding out a violin.sherlock nodded and took the instrument, waveing his friends over. Tony made sure his suit was in its briefcase form and got into the helicopter behind John,  just close ing the door before it took off.
"I am assuming you have been properly informed?" Mycroft asked.
"Definitely. And how did I not find out about the flat blowing up?" John asked curiously.
"I have connections."
"I see. I have been told that you are practically the British government." Tony stated.
"Mostly true. I have a large influence. I even got my brother off of murder." Mycroft smirked. Tony's eyes widened.
"What!?"
"Killed a guy who knew about Mary's old job as a government agent. He knew secrets about everyone of importance in the contry. Every single pressure point. He could have owned the contry if he wanted." John explained. Tony was even more shocked.
"I give up. I give up. A government agent?" Tony gulped.
"She was supposed to be dead. One of her old team members came and tried to kill her a wile ago acctualy." Sherlock said calmly, as though that was the most normal person in the world.
"Is this how people feel when I tell them my life story?" Tony laughed, leaning back.
"Probubly. Anyway, are you two ready to meet my wack job sister?"
