A/N: Thanks for the reviews. I've done a few caring!John drabbles/oneshots on here so I though it was time for some BAMF!John. Enjoy!

The case had led them to a darkened school hall at around 9pm. Sherlock had run off without John leaving him a few minutes behind. One problem about this night was that the police were even further behind and they didn't know exactly how far. It was one of Dimmock's cases and John was beginning to agree with his flatmate that the man was every bit as 'Dim' as his name suggested. Not only did he check and triple check every one of the consulting detective's suggestions, wasting valuable time, but he'd said it would take over an hour to get a team together to storm the school which was frankly ridiculous. He was obviously trying to delay things so that it looked as though it was his idea in the first place.

But the real reason John was so annoyed with his colleague was that he'd now run into a situation of danger with no back up apart for the ex-army doctor who was delayed. They needed to have a little chat about this. If they got out unscathed, that is.

Having found where the detective has entered the building John began to kick one of the doors down to get in, then finally made his way into the hall to see Sherlock being thrown to the ground and repeatedly kicked in the stomach while three others were carrying boxes away at great speed. The tall brunet was usually very good at hand to hand combat so something must have happened. Between his bartitsu and boxing skills coupled with his light, speedy body the attacker must have claimed the upper hand almost instantly, injury with a weapon was a possibility.

All of a sudden John was over there almost silently and ready to end this. The criminal was yanked backwards away from the winded detective. "Hey!" the man exclaimed thinking it was just the two of them in the room before he had a fist to the nose then jaw and was down for the count.

Next a knife wielding assailant who had run back into the great space after hearing noise was onto the blond doctor not seeing him as a threat. John gave a harsh little grimace before knocking the hand out of the way, kicking the man's thigh then grabbing and bending the arm until the weapon was dropped. Not understanding his predicament the bald criminal went after it again but the blade was kicked away. Still being held, there was a sickening crunch from the limb and he stumbled off screaming in pain.

John straightened himself and cracked his neck calmly, daring the next people to make a move. His bright eyes were narrowed and everyone sensed danger. However, they kept going. Two unarmed men ran up now as Sherlock looked over helplessly, trying to get his breath back as he rocked back and forth on his knees and elbows, gasping and spluttering. He was left alone as all attention was on the one in the oatmeal toned jumper who was systemactially taking them out one by one.

Instead of delaying anything John who looked more of a solider than ever approached the first one, blocked a punch and then landed his own into the man's abdomen, slamming an elbow directly down onto the back of the guy's head as he bent forward in an attempt to suck in some air causing him to fall hard, arms splayed.

The next crook hesitated which was his undoing. John said clearly "You've seen what I'll do, just lie down, the police are on their way"

"I-I can't let, let you live" the man stuttered, eyes flicking from his attacker to the ground where the knife lay. He couldn't believe this was happening, especially not by a man with the physique and dress sense in front of him.

John sighed, rolled up his sleeves and began to walk over. The thief stilled then began to move backwards, tripping over his own feet. When he tried to get up John said "Stay down and you won't get hurt".

The idiot didn't take the warning and as he raised himself on shaking limbs, the combat trained blond sighed and gave him a blow to the head, knocking him back down to the ground. He responded by whimpering and staying there.

John turned around as he heard footsteps racing in and saw a team of Scotland Yard's finest finally here to do what they should have done ten minutes ago. It wasn't their fault though, that blame rested with Dimmock.

As the group of criminals were rounded up John noticed that people were watching him carefully without saying anything. But really his eyes sought his friend who was still on the ground. He walked over and extended a hand to help him up which was gratefully accepted. "...winded..." he explained in a wheezing tone. "First guy...threw something...at my head...was dazed...should have seen it coming...stupid..."

John was glad he was unhurt apart from the obvious but still wasn't impressed. "No, you should have waited for me, that's what you should have done. I hope you've learnt your lesson. You're lucky you weren't killed!". He gazed around the room to see that most people were eyeing him with varying expressions. Something strange was going on and he wanted to get to the bottom of this.

"John" Sherlock began but was ignored.

The doctor had his phone out and was using the light from it to test Sherlock's pupils for concussion. "Get one of the paramedics to check you out, but I think you're ok. I have someone to speak with". At this the ex-soilder strode over to the largest gathering there. "You took your time" he accused the DI in charge.

Dimmock stopped talking to a Detective Sergeant, swallowed, then raised his head so he was looking down his nose a little which didn't work so well as they were around the same height. "I got the team together but you two seemed to think you had the right to come in here and deal with things yourself". There were noises and raised voices all around them as the situation was beginning to be cleared and organised.

"Well someone had to, didn't they? They were about ready to leave. I know what Sherlock is like and I accept that but there were some serious delays from your end" John returned, adrenaline still pumping through him. At his words more people turned to watch him but he tried to pretend that they weren't looking at him. It was almost as though they were...scared of him? Reassessing him? "What is the matter with them?" he asked without as much heat, pumping his fingers in and out of a fist.

"Well, the doors were locked and it took us about a minute to get in but we got a full show of you disarming all the assailants". As this he indicated to the various points around the hall where the police would have been able to see him take down four men, some armed, as though he were doing nothing more taxing than walking through a shopping centre during the Christmas rush. "It was..." he stopped, seemingly looking for the right words while watching something over John's right shoulder "...pretty bloody impressive, I have to say". At this he bristled and set his lips in a bit of a pout ready to be insulted.

John felt a hand on his shoulder but didn't need to turn around to see who it was. "Four...that's all of them, Dimmock. Do you need to ask everyone here if they saw that before you can arrest them?". He didn't wait for a response before turning to his flatmate. "You don't understand the reaction. Everyone underestimates you and were shocked and impressed by your display. They are wondering how the short man who like jumpers and tea can fight like that"

"What did you tell them?"

"That you're John Watson" he said as though that cleared up the matter entirely. "Good day, Dimmock. Enjoy the paperwork. Your presence was as intolerable as ever" he said to a stunned DI and walked off with his friend.

"Did you really say that?" the shorter one questioned as they got further away from their audience.

"That you're John Watson? Of course I did"

"Right"

"Also someone called you a ninja, I didn't correct them. People watch for too many movies and that's not my fault"

"A ninja? Haven't had that one before". He then looked up at his friend's face. "What's wrong?"

"I'm just annoyed that it takes something like this for people to see what use you are. I told you people are idiots"

"Are you buttering me up so that I don't yell at you for going in there by yourself?"

"A little. It's true, though"

"Come on, you. Let's get something to eat. Chinese?"
