Sherlock meets the Avengers- A crossing of fandoms

Sparring

"This realy isn't a very good idea." Sherlock stated mater of factly. He had changed into a lighter shirt and pants, figuring he would be fine. He didn't have any real fighting clothes.
"Oh relax! You are no fun!" Natasha laughed. She had slipped into a shield issue training jumper, all black exept for a couple shield logo's spotted on the sholders.
"We're about to spare with Black Widow. We are about to spare with an Avenger. Mind telling me how we are supposed to relax?" John grumbled loudly. He had brought some of his old army gear, so he threw on one of his lighter uniforms, desideing to place his rank on his chest.
"By getting the adrenaline pumping, soldier. A captain. You and Steve should share some story's." The woman laughed, stepping into the circle in the center of a large training room. The floor was covered with blue mats and had red lined showing the circle and other spaces for other purposes. The walls are white and the roof is the same, there was lots of gym equipment peppering the room, still leaving the center empty for sparring.
"Oh, wonderful. That's great. Alright, let's step into the circle of death."John grumbled, stepping into the very edge of the circle. Natasha laughed.
"Two againsed one or one on one?" Sherlock questioned, not sure about what answer he wanted.
"Sherlock! Get your ass in the stupid circle!" John growled. He was not going to fight Black freaking Widow on his own.
"Fine." He grumbled, nervously stepping into the circle. Both boys got into a surprisingly good fighting stance. Natasha smiled aproveingly.
"Now remember, watch your back. Look out for yourselves. Keep your eyes on your enemy at all times. Don't be afraid to hit me, I spar with Steve and Thor all the time. I can sure as hell take more than a punch. Use everything you know, even dirty moves." Natasha explained, starting to circle around on the line. The boys copied, takeing everything in.
"Figured. Let's get this over with. Bruce? You might need that first aid kit." Sherlock gulped, keeping his eyes on Natasha but talking to the doctor.
"I doubt you'll hurt Natasha."Bruce laughed. He stood on the edge of the room with the others, leaning againsed the wall.
"No, for us." Sherlock finnished, causing Bruce to laugh again.
"Oh, she won't hurt you to bad." Bruce laughed out, not moving from the wall.
"Ok. Enough talking! Let's go!" Natasha yelled, running towards the boys across the center of the gym. Sherlock and John's eyes widened and they dodged the charging woman, putting themselves in the center of the circle. Sherlock didn't just dodge though. He used a pressure point on the back of the woman's neck, karate choking the center of it. She stumbled and laughed.
"Yes! There you go! Alright. Good to know your not afraid to fight dirty." She laughed, this time approaching slowly, watching everything and not underestimating them. With one quick look and a nod, the boys seemed to communicate telepathically, because they separated and flanked the woman.
"Ooh. Good move. But not good enough." The red head smiled, waiting for them to come at her. She swiped her feet to nock John down and punched sherlock in the nuts at the same time, or, at least aimed to. John saw it coming, s just like Steve would, and jumped over her leg, landing on top of her. Sherlock smiled.
"Thankyou John." Sherlock laughed. He instantly stopped though when his friend whent flying across the room. Your dead lady.

Sherlock pounced, wrestling to pin her. Natasha got several good hits off, but so did sherlock. The second Natasha almost had sherlock pinned, John pounced on Natasha. He tackled her off his friend, hitting her in the midsection. He then a tempted to do an army pin, only getting almost thrown off. Natasha smirked. She quickly kneed John right in the balls. He yelped painfully and fell off her, groaning. Several people groaned or winced seeing the blow, earning John an 'ooh! Nutshot!' From Tony. Sherlock was done. He ran at her, throwing a punch to distract her and aiming for the stomach. The wind was knocked out of her, but she simply jumped up at him. He dodged, as expected, and Natasha jumped on him from behind. She wrapped her legs around his neck and brought him to the ground. He was almost out of air when she let go and had him pinned.
"I win. But you did last longer than expected. Props. But don't let your rage control you. Use it againsed your enemy." Natasha smiled, slightly out of breath. It barely showed though, compared to sherlock, who was recovering from the choke hold. John however, had managed to get to his feet. He stood shakily, taking a couple painful looking steps before walking properly.
"I-I think you broke by balls!" John laughed, obviously joking.
"Hey! Good job! I useualy have Clint on the ground for 20 muinets." Natasha laughed, crossing her arms over her chest after a little bow.
"You also kick way harder with me!" Clint growled, walking away. "Good fight though." He added with a smile. John and sherlock nodded in thanks and walked away, sherlock stopping for a moment to speak.
"Remind me never to spar with you again." He laughed. Everyone laughed as well and let the boys go relax, or, tried to.

10 muinets later, after sherlock, John, and Natasha had changed, Fury called.
"Avengers, and company, we have someone asking for you at shield. They say their from London." Fury stated, stoic. He had the continually strong posture still going for him. He had lots of people milling about behind him.
"What do they look like. If it's who I think, you need to send them back to London." Sherlock questioned.
"Their names are Molly Hooper and Greg Lestrade." Fury stated.
"DANMIT! Send them home! They can't be messed up in this." Sherlock stated. It would have sounded like an order if it hadn't sounded pleading.
"I'm afraid it's to late for that." Fury stated, as if on cue, Molly and Lestrade walked into the room akwardly off the elevator. Sherlocks eyes widened.
"No. No no no no no. No, you can't be here! It's bad enough that John has been dragged into this! You need to go home. Or to shield. If one of Moriarty's goons saw you-" Sherlock started to say, running a hand through his hair. He was cut off by Molly running over and hugging him, shutting him up. He had his arms out in surprise for a moment, not sure what to do, but eventually hugged the woman back. She was latched onto him around his ribs and she had her face buried in his chest.
"Your an idiot, Sherlock Holmes. Do you know that? You had everyone worried sick!" Molly spoke into his chest, squeezing tighter. Her voice was muffled, but audible around the room.
"Oh, this isn't about the fake death thing again is it? Didn't John leave a note or something like that?" Sherlock groaned.
"Sherlock! We thought you were dead for two years! Of corce were going to worry! We'll always worry after that!" She growled, pulling back to smack him on the arm and point at him. Sherlock raised an eyebrow and smirked.
"You all worry to much." Sherlock laughed.
"We need you back in England, sherlock. You to John." Lestrade stated.
"Well, unfortunately the world needs me here. Shield came to John and I to help them find Loki. And now it turns out that Moriarty somehow has control of him. Whatever is going on back home can wait. But you two," Sherlock explained, stopping to point at lestrade and molly. "You two need to go home. Better yet, go to shield for protection. I can't have anyone I care about die." Sherlock finnished. Molly and lestrade were shocked.
"Loki? Moriarty is controlling loki?" Lestrade choked out.
"Um, ya, hi? You just walked into my tower without me letting you in? How did you get past Jarvis?" Tony asked, standing up and walking over. Molly and lestrade stood wide eyed, finaly realizing there were other people in the room.
"Oh my god..." Lestrade gulped. Molly simply hid behind sherlock.
"W-we were told to just come to this floor by shield. Jarvis just let us in. We were only told that sherlock and john would be here, we didn't know that... oh my god." Molly rambled, shocked. The avengers were right in front of them.
"Danmit Fury." Tony grumbled. Sherlock gulped.
"Uh... this is Molly, my mourge tech and lab helper. She is very intelligent. And this is Lestrade. He is with the Scotland Yard. He useualy gives John and I the tough cases that he can't solve. If everything goes my way they will be gone and safe in-" Sherlock started, pulling Molly out from behind him to introduce her and waveing lestrade over to introduce him. He was cut off by Tony.
"Nonsense. They'll stay here. If Fury is going to send them to me I might as well fill up more guest rooms. Besides. The safest place they can be is here with the avengers. Nice to meet you. I'm guessing you already know who we are." Tony stated, causing sherlock to pale. More people to protect. Tony stuck his hand out for Molly to shake, laughing when her hand reached out shakily. He then shook lestrade hand as well. The other avengers smiled and came to say hello. Sherlock simply stood away from everyone, leaving the newcomers to fend for themselves. When John noticed sherlock looking at the mob of people, he came over.
"Hey, you ok?"
"No. I'm worried about them John. About everyone. The fate of the world is on our sholders. I don't know if I can do this."
