A/N: I clearly do not own Sherlock or Avengers. I only own a part of the plot.

(This chapter has been edited)

Tony Stark had just escaped from the hands of the Ten Rings; thanks to Yinsen and his robotic suit that protected him from all the explosions. Though he was severely injured and needed medical help soon. But apparently, fate had other plans.

Just when he thought that he had successfully escaped, he had been captured by some men and brought to a cave where another man was hanging from the other wall.

Tony silently gauged the tied up man. He was deathly pale. Judging the wounds that were visible on his bare chest, he assumed that this man had been there for a few days, tortured for information - assuming he is correct. The wounds were clumsily wrapped, proving that they didn't want to kill him.

He also noticed that the man wasn't asleep, judging from the rise and fall of his chest. He could hear the laboured breathing of the man from where he was tied. From the shredded clothes scattered around, he could say that this man was from a high-class family or some high official.

Tony couldn't, unfortunately, identify where exactly he was as he was still groggy from the hit on his head. All he knew was that he was in some desert region, given to the clothes worn by his kidnappers and was a few meters deep into the ground, judging from the coolness of the cave.

He looked around, trying to figure a way out of this place and was disappointed when he could find none, except the entrance which was heavily guarded. Feeling bored and exhausted, he couldn't decide on what to do when he heard a small groan from the other man in the room.

"You alright there dude? Who are you? why have they brought you here?" Tony asked the man. The man groaned again, before answering in a gruff voice, hoarse from constant screaming.

"James Crate. They've been asking me to join them for a long time for reasons I don't know and information I am not willing to give. Who are you? Why are you here?" James asked, turning to Tony. He was shocked at the plight of the man. His face had been scarred badly. His eyes shone bright with unshed tears, trying to hide the fear and pain.

"Anthony Jackson. I guess I am here to build weapons for them probably. Nice to meet you Mr. Crate," Tony said, smiling slightly at the man in front of him. Before James could respond though, a few men entered the room, smiling devilishly at the two people in front of them.

"Getting to know each other I see. Mr. Holmes, I ask you again. Will you join us or not?" The masked man asked, most probably the leader. James Crate or should I say, Mycroft Holmes weakly glared at the man. "My answer is always the same you bastard. Nothing you do will change it" Mycroft spat out.

"So sad that you are not joining us here Mycroft. Boys, the usual" the man ordered. Said men moved forward towards the British government official and started hitting him with pipes and hands. Mycroft just grunted in pain, mostly used to it but occasionally screamed. Soon they started cutting him.

Tony watched all this in mute horror but could do nothing to stop them as he was in a helpless situation. The leader, who Tony had decided to call as Mr. X, finally shot a bullet to the leg of Mycroft before turning towards Tony, not before asking his men to patch up Mycroft.

"Now Mr. Stark, You probably know why you are here. Are you willing to design the weapons for me or not?" Mr. X asked with an insane smile that promised torture if refused. Remembering his promise to Yinsen, Tony refused to build the weapons, earning the wrath of the man.

Soon, Tony was experiencing the same service, excluding the bullet to his leg and the carvings in his skin. Though he was pounded to unconsciousness. This went on for a few days. The man would come and ask them a question. They would refuse, they were tortured and knocked out. The two used this time to get to know each other.

They talked to each other about their personal life, what they do for a living. Soon became fast friends as they got to know that they had many similarities from the conversations they had.

This went on until the man came to them and forced them out of the chains. A bag was forced on their heads before escorting them outside. When they were outside, the bags were forcefully removed from their heads, leaving them blinking at the sudden light and heat.

"So, Mr. Holmes and Mr. Stark. Do you accept the offer and join us or more torture?" the man in front of them asked. The two men looked around, still trying to adjust to the light outside while shaking their head in a firm no, only to be punched on the nose and kicked in the guts before they were dragged inside the cave roughly.

Once back inside the cave, they were beaten some more before the men left. The two were silent until they heard the sounds of trucks leaving the place, confirming the fact that 3/4th of the group had left, leaving behind only a few men on guard.

"Do you think we will be found?" Tony asked Mycroft. Both knew that it was futile to try and escape as they were weak and overpowered. They were hoping that someone would find them, even though the hope was dwindling as time passed.

Mycroft remained silent and was roaming around in his mind palace, reviewing memories of the old times where his brother wasn't withdrawn from everyone, though it was partially his fault for ignoring him unintentionally. He smiled at those memories, trying to ignore the outside world and the immense pain he was feeling throughout the body.

Realising that Mycroft was in his mind palace, Tony closed his eyes and sighed, before drifting into a light sleep. He knew that if they didn't have medical attention soon, they would be infected and would be in serious trouble. He just prayed that someone would come to rescue them.

Two hours later, Tony was brought back to the real world to the sound of gunshots. Wincing at the searing pain that shot through him at the sudden movement, he stood up and grabbed on the nearest weapon he could find, which was a wooden plank to defend himself and his friend.

Tony stood near the entrance, waiting in bated breath for people to come in so that he could take them down. But when the door opened, it hit him on the face, causing his legs to give out and he fell to the ground, hitting the head hard to the surface and slipped into the blissful darkness.

Two hours earlier

The sun was blaring down furiously in the Afghan sands, heating the place up tremendously. A lone man was walking through the desert. He had a small pack on his back and a gun on hand. He had been scouting this place for quite some time, trying to contact his team nearby about the recent activity he had witnessed.

It had been a long day of travel for him and his team. They had been instructed to look into some suspicious activities around the place. So while his team was setting up the base, he decided to take a break and walk around a bit nearby.

He seemingly had the best luck and the worst luck as he had stumbled upon a terrorist base accidentally. He quickly his behind the rocks, trying to listen in on what was going on. When he couldn't hear anything, he risked peeking, only to find two people brought out to the man in the entrance.

He could clearly distinguish between the local dialect of the man and the British and American accents from the other two. Even from a distance, he could tell that they had been tortured for days and tried to contact the base when he saw trucks leaving the place with most of the men.

He was starting to get frustrated with no response from the rest of the team. 'Not much time before they collect these two men John. It has to be done now. Even if they aren't sent to the base, they will probably die from the injuries before backup arrives.' John muttered, trying to convince himself. He tried to send out one last call deciding to go ahead and break into the base.

He got to the caves with ease. The problem was presented inside. The deeper he went inside, the more people he could find guarding the place. He successfully killed the border guards and looked around, and spotted spots of blood leading to a place where there seemed to be many guards.

He spotted a guard coming towards him and quickly took action. He jumped on him and twisted the guard's head until he heard a crack before he got up and quickly dressed up and went inside.

He quickly shot two of the guards with his rifle and made his way forward to face 6 gunmen who were in front of him. They rapidly started firing at the intruder. John dodged most of them with ease. Four bullets caught him by surprise, and he was knocked back to the wall.

He groaned as he sat up quickly, thanking the military for providing with the body armour as otherwise, he would be dead. He was expecting nice bruises and maybe a cracked rib. Firing 6 shots at each man and hearing the bodies fall to the ground, he quickly made his way to the door where he suspected the captives were held, not before checking if the guards are dead.

Quickly but quietly heading towards the door, he heard some shuffling before he unlocked the door quickly and caught a thud to the side, causing his head snap towards the noise, only to find one of the men he came to rescue knocked out on the ground and he suspected that he would get a nice concussion from the force he fell down.

He immediately set to work of cleaning the wounds so that it won't be infected and then proceeded to scan him quickly to spot any other injuries and swiftly worked on stitching the deep one and bandaging him up, leaving the device in the middle as he didn't know what it did. Though he decided to ask about it to the man after he woke up.

His eyes then landed on the wounded Mycroft who was in his mind palace. He quickly moved over to him and checked for a pulse, which seemed to bring him out of his musings as he flinched at the contact.

"Don't worry, sir. You will be escorted to safety after I do a basic checkup on you." John said as he brought out the first aid kit and set to work, quickly checking for any damage, and he sedated the man and proceeded to tend the wounds, cringing at the numerous carvings and bruises, the worst one being the bullet wound that seemed to need immediate attention and signs of infections.

He quickly bandaged him up to avoid the other wounds from being infected, he heard the man say something like "Tony... also here... must be rescued" before slipping into a deep sleep as the drugs took control. After bandaging him up as much as he could in a hurry, he sat down to think about his next course of action. He couldn't ignore any one of them and take the other back to camp.

He also knew that he could treat them properly only when he reached the base, where they had the necessary equipment.

So he decided to ignore the pain flaring in his body from the bullets caught in the armour and lifted one onto each shoulder, holding his handgun in one hand as he moved outside, looking back occasionally to check whether anyone would jump them.

Soon, he made his way out and started to switch between a jog and a march for a whole hour before deciding to rest, deeming that there was enough distance between the base and themselves. He then set the two men down to redo the bandages.

John was so busy checking his patients, he never noticed one of them starting to wake up. He was aware of it only when he heard one of them let out a startled scream and hissed when the pain hit him.

"It's alright sir, you don't have anything to worry about. I am just checking him for injuries to treat upon." John said, calmly while he was doing a checkup on Mycroft and removed the mask he had got from the terrorists. Tony calmed down as he saw the man's face, though was immensely confused at what was going on.

"This wound needs immediate attention. But I am limited to use the resources in hand until we reach back to the base," John said, pointing at Mycroft's injury with concern. "It is ok to be confused, you have got a nice concussion from that hit you suffered by hitting the door," John said. Tony nodded. His brain was still fuzzy from the concussion.

"Alright, we need to get back to the base before anyone catches our tail. I am going to redo your bandages now. Please sit still." John said as he finished up with Mycroft and sat next to Tony to check over.

"Um... I think I didn't catch your name? Where are we currently? I am Anthony and that one there is James." Tony said.

"Sure, Tony. Nice meeting you. I am Johnathan, we are currently in Afghanistan. I hope you can walk some distance?" John asked as he finished dressing up Tony.

"I think I can do so. Can I contact someone after reaching the camp?" Tony asked as he got up, slightly wincing and leaned on John for support. John grunted as he lifted up Mycroft, which didn't go unnoticed by Tony.

"Are you alright?" Tony asked as they moved forward. "Nothing serious to worry about Tony. We can contact your friend after we reach camp. I am sure we have some unanswered questions that will be answered there." John said. The two of them started walking way slowly in comfortable silence until they saw shadows in the distance, causing John to take out his gun and...

A/N: Chapter 1 of this fanfic people! I would say that this idea came from reading the books You See The Battlefield and If He Be Worthy by AndyHood. A Sherlock and Avengers crossover as you can see, I have made a few tweaks in the timeline here which I will confirm in the upcoming chapter (aka, chapter 13).

Hope you all liked it! All comments and criticism accepted and appreciated from you all. Any honest reviews will be welcome.

Thank you all for reading!
