Sherlock meets the Avengers- A crossing of fandoms

"The game is on."

The second the group had gotten out of the cab after the plane ride, John was in aw. Sherlock simply smiled, noting everything he saw. They would be staying in avengers tower for their stay. Tony wasn't exactly sure how he felt about that, but he would have to suck it up. Sherlock and John were only givin enough time to drop their baggage in guest rooms and have a quick tour before they were wisked away with the avengers to see the last known location of loki.
"So, this is the last place we have knowledge of him being. We have been searching for a wile and we are hoping you can find something." One woman, agent hill, explained once everyone was on the scene.
"Wonderful. Tell me what you already know and show me the evidence you've already found. If I'm better than your people I should be able to find some things you've missed." Sherlock smiled, exited about haveing something hard.
"Please bring all evidence to lab tent 3." Hill spoke into a com in her ear before explaining."Loki seems to have just upright disappeared. He simply Telaported away. He has put some sort of spell on all our equipment, so we have to find him on foot or in vehicles. None of our tracking technology will work." She explained, leading them to a tent.
"Oh! I love the smart ones! Always such a challenge!" Sherlock smiled, Agent hill raised her eyebrows at him.
"I will hand you over to agent Colson. He knows more about the evidence than I do. I am mainly on the tech this time." Agent hill finnished before letting the team plus two into the tent and leaving.
"Ah, agent Colson I presume." Sherlock stated, already deducting as much as he could about the man.
"Yes, that's me. Anyway, I should get to explaining. All we have is intense fragments of magic from where loki Telaported away. We need to get our equipment up and running to trace where he popped away to. We were hope it you could find some more physical evidence for the-" Colson explained, almost finishing before he he was cut off by a yell, plenty of gunshots, and a scream. Sherlocks head jerked up and he ran for the noise. Someone was screaming for a medic, so John and Bruce followed with the other avengers in tow to kick ass.
"LET ME THROUGH! I'M A DOCTOR!" John shouted, shoving agents aside. Agent hill had a large hole in her arm, a note in a plastic bag in the hole. Several agents were trying to treat the wound. Bruce and John had paled but got to work anyway.
"Bring a hospital bed over! We need to get her in one of he labs!" Bruce called, several more agents ran off to compleat the task. John removed his shirt and tied it around agent hill's arm, tightening it to make a turnicet and slow the blood flow. John slowly pulled the bag out of the hole in the agents arm, handing it to sherlock to examine. He ripped open the bag and slowly pulled out the note, not wanting to get it ripped. He unfolded it and read the note, paling.

Hello, old friend.
Life has been much to easy for you recently. So I figured I would give you a little caos. I have managed to take control of this evil god. Loki, odd name. He will now do my bidding. You will have a hard time being bored now, won't you Sherlock? I hope you enjoy this. What is it you say before a case? "The game is on" ?? It most certainly is, my friend. Did you miss me?
-Your best enemy, and biggest fan, Moriarty.

Sherlock was white as a ghost. Not again... he dropped the note, the corner of the hand-written letter soaking with blood. If Moriarty can take control of loki, he can do anything. People were going to die.
"Sherlock? sherlock! SHERLOCK! We need your help!" Bruce yelled. Sherlock nodded, picking up the letter and putting it into his pocket. He got down on his knees to help.
"What do I do? Your the doctor!" Sherlock stated, stareing at the hole in the agents arm.
"Think of this like the guardsmen! Just realy intence! Do what I say and we should save her! We need to stop the bleeding. Once we get her to a lab we need to dissingfectent the wound and burn the blood vessels shut!" John explained.
"Burn them shut!? Are you mad!?" Sherlock cried.
"It's a medical procedure that is used in surgery all the time! Help us get her on the bed!" John ordered. Bruce was checking for other ingeries and keeping Johns shirt tight around the woman's arm, slowing the bleeding. The three of them heafted the woman onto the bed. The whole time she had been screaming, not a single agent blamed her. The second they were in the lab they got to work. They had to strap agent hill's arm ddown to the table to keep it still.
"No time to sedate her." Bruce stated, medical mode on.
"Sherlock! Get that jacket over there! She will need something to bite down on."John stated in his army voice. Sherlock grabbed it and folded the sleeve of it once before letting the woman bite down on it. John grabbed a disinfectant from a shelf and poured it on generously. It must have burned like hell, because agent hill screamed even louder and bit down on the sleeve. Sherlock went to remove the sleeve but John stopped him.
"She'll need that again." He stated simply. He hen took a tool from the med tray someone brought him, turning it on. It was red hot instantly. Sherlocks eyes acctualy widened. "You should probubly hold her other hand." John instructed. Sherlock did as he was told, instantly regretting it. The woman clamped down on his hand with hers, holding tight enough to make sherlocks fingers crack. He hissed but didn't let go. The second John started doing what he had to do, agent hill screamed even louder. Bruce had to hold her arm down despite the straps. Natasha had run in and started being supprizeingly soothing, rubbing her hair and whispering into the other agents ear. The patient was crying and screaming, but once it was over and John could finaly sedate her, she seemed so peaceful.

"Thankyou, you saved her life. But we can't let you be a part of this case anymore. We can't let that be one of you." Steve stated firmly an hour later once they had gotten back to the tower. "This isn't your business, we shouldn't have dragged you into this." He added with a sigh.
"Unfortunately, your wrong, Captain. Moriarty has a part to play in this..." He swallowed, fearful of the man in question.
"Moriarty?" Tony asked.
"Yes, he is the one person who ever managed to outsmart me for any period of time. He is the one I jumped off the roof to save John and the others from. He has control of loki... he left me this note..." Sherlock growled, hateing the situation. Everyone took turns reading the note. Thor was emanating danger. You could feel it.
"I have to save my brother! Despite what he's done!" Thor boomed.
"We have to save many more than your brother. So many more." Sherlock stated solomly "People are going to die."
