The Detective, The Wizards, And the Ninja

Authors Note: Hi, thanks for clicking! I hope you enjoy it, just some quick notes for understanding. I know there are going to be issues considering how far out a crossover this is but I don't really care. If something doesn't make sense because of back story lines or something just ignore it, its what I do.

Detective Marty Deeks of LAPD was currently driving a large, 10-seater, black van to the airport. He wasn't very much relishing the thought of picking up and housing these eight particular people from his past. As much as he sometimes missed magic and Hogwarts and the wizarding world in particular he had left for a reason. As he turned to look for merging traffic his golden hair shone from the light of the sun and he was reminded of how it had been black so long ago. The only familiar part of his appearance was his blue eyes; the rest of it had changed. He had used magic to cover his scars, fix his eyesight, and dye his hair blond and police training had wrought a complete change on his physique. The only people who would recognize him now were the Weasleys, Neville, Luna, and a few of Hogwarts' professors, he could only hope that these people would not expose his new identity.

The reason he was driving to the airport in the middle of the workday in an extended van was to pick up eight of his fellow classmates from Hogwarts…the purebloods anyway. The wizarding world had recently had an encounter with muggle forms of violence and had finally realized how out of touch they were with the reality surrounding them. So the minister of magic had begun a program to integrate wizards who were not aware of the muggle way of life by housing them with those who were. Over the next few days Marty, or Harry as he had been back in the day, was going to take them to work, show them around the city, and basically house them all in his one bedroom apartment…which he was not going to modify with magic.

Deeks hadn't used magic in years, with the exception of occasional defensive training with Ron. After the war his life had been so bad that he had left, changed his appearance, accent, past, and attitude and became the man he was now…LAPD Detective Marty Deeks holding the liaison position with NCIS OSP. To the wizarding world, well most of it, he had simply dropped off the face of the Earth. Somehow though, Minister Shackelbolt had found him and practically begged him to be a part of the project. Eventually he had been convinced, mainly because he wanted him out of his house so he could go get drinks with the team, guess it would sort of help him face his demons or something.

Hetty had already informed everyone at ops so that nobody would be surprised when eight random guests casually strolled through mission. And lucky for him Sam had arranged some SEAL tactical training examples, in which he had a bad feeling he would be the sacrificial punching bag, and Callen had volunteered to man the shooting range. Kensi, he had a feeling, would be probing his classmates for information, and enjoying watching him squirm to try to keep them under control. Nell and Eric would probably be running facial recognition to try to see if any of them are hidden drug dealers and Hetty would be popping up and scaring the hell out of everyone on a regular basis. God help him if they actually got a case.

A dozen thoughts a second were running through his mind as he parked and walked into the large airport clutching a white sign under his arm and checking that his badge was visible and his gun as safely concealed. After the normal hullabaloo of going through security with a gun he made it to the pick up center and raised his sign as people began to walk out of the terminal. He quickly spotted eight confused looking passengers who were barely hanging on as they drifted around like they were high on something. If they were he was definitely going to be taking some to get through these next few days, maybe he still had those pain pills from when he was shot…nah, Hetty would know and kill him if he tried. After a few minutes of his passengers looking around they spotted his sign and walked cautiously up to him.

"Is this sign a joke?"

Deeks looked down at his sign. It happened to read 'Eight confused passengers looking for a ride and a lightening bolt scar."

"No." He replied with a smirk, trying to see how far he could push Malfoy during the first two minutes of this hellish day.

"I'm sorry, who are you?" Hannah Abbott stepped shyly forward, though she was half-blood she, as well as another of his wards Dean Thomas, had been raised in the wizarding world and were just as ignorant of the muggle one as the purebloods.

"Well now I'm known as Marty Deeks but you knew me as Harry Potter." He replied, inwardly cringing at how foreign his own birth name sounded.

"What?"

"That's you?"

"What happened man?"

"Please, lets continue this conversation in the car, if you'll just follow me. Once we're in a secure location we can talk." Marty replied, for once acting serious.

All eight people: Padma Patil, Draco Malfoy, Ernie Macmillan, Michael Corner, Cho Chang, Daphne Greengrass, Dean Thomas, and Hannah Abbot, looked at each other to which they all shrugged and picked up their bags and followed him out of the area. Luckily he was fortunate for security to recognize him upon their exit and not stop him for a gun inspection. After walking a few minutes they made it to his rental van.

"This is your car Potter."

"No Draco, this isn't my van. My car isn't big enough for everyone here. Note how I called you Draco, its nicer." Deeks replied somewhat sarcastically, he could swear he heard a snigger from his small crowd and he was slightly suspicious it was Cho.

He loaded everyone's bags in the back while everyone got on. He took his time getting into the drivers seat and locking the car before turning to face everyone.

"Look, I'm going to tell you guys what you'll need to know once we arrive at my place but in case we get stopped on the way there I'm going to give you a little bit of information. My name is no longer Harry Potter; it hasn't been since I was eighteen. Its Marty Deeks now, I'm a police detective with the Los Angeles Police Department but I work within NCIS or naval criminal investigative services as a liaison between the two agencies. The specific operations center I work with is the office of special projects although before joining I worked mainly undercover. According to my file I'm two years older than you know me, I went to an unknown boarding school in Scotland after I shot my abusive father non-fatally when I was eleven, there is a long and painful story behind that cover so please don't ask. And I own a dog named Monty. Any questions for now?" Deeks rambled out just slowly enough for them to understand.

"Um…. Why do you think we'll get stopped?" Ernie asked.

"In the line of work I'm in its always a possibility." Deeks answered non-descriptively.

He started the car and put it in reverse. Everyone behind him just looked at him confusedly and at the others very weirdly. They had obviously been expecting to see an exact replica of the Harry they knew.

"So, what do you guys want to talk about?" Marty asked casually.

"Why are you talking all weird like that?" Michael Corner asked.

"It's an American accent and part of my cover is that I've lived in California all my life so I've appropriately adapted my accent to that." He answered easily.

"What's all this cover for?" Cho asked curiously.

"To be honest the wizarding world was always putting me on a pedestal and that and the fact that I wanted a new life meant that I changed my history as I changed who I was so that nobody could find me." Deeks answered almost regretfully.

"We get it Marty." Dean replied leaning over the front passenger seat to flash him a smile.

"Thanks man, and put your seatbelt on." He laughed as all eight people looked confused at the fumbling device.

"Don't worry, you'll figure it out soon." He chuckled.

The next twenty minutes passed in much the same fashion, with everyone talking collectively. It surprised him to find that Malfoy had changed quite a bit and had even abandoned the animosity towards him that they had had since the age of eleven. It was while they were debating the merits of muggle vs. wizarding music when Deeks started to realize a small black car with tinted windows was tailing him. Because of the traffic angles he couldn't make out the license plate. For the next two miles he took wrong turns and changed speed until he couldn't deny that they were tailing him. The car couldn't accompany more than four people with small caliber weapons, three if they're carrying something more serious. He was already close to both his house and mission and he didn't have the time to call back up and risk leading them to either location. He started to turn down an alley before raising his voice and directing orders to the people in the car.

"Listen, we're being tailed right now. I can't call for back up and risk leading them to mission. I need you all to duck below the window line and wait until I get back to get up. If I don't come back and they come for you then use magic, but otherwise keep the wands hidden."

They all started looking worriedly at him but followed the orders. The car skidded into place as he parked. He grabbed the gun from the small of his back and reached into the passenger seat glove compartment. His passengers watched in avid fascination as he quickly strapped his old LAPD police vest over his chest and grabbed an extra battery for his Beretta.

"Stay down." He instructed before exiting the car and running over to the edge of the warehouse he had parked in.

Despite his orders everyone was watching through the tinted glass. They were extremely confused by his actions, even more so when they saw him check the safety of his gun before raising it in front of him and stepping out into the open.

"LAPD, identify yourselves." He yelled forcefully.

Suddenly the wizards in the car saw him lower his gun and pull of his vest before raising him arms to either side in a questioning stance. He turned back to the car where he threw his extra rounds and vest into the passenger seat and told them it was safe to come out. It could have just been their ears but he sounded especially exasperated. They exited the car and saw him talking to a tall black guy and a slightly short brown haired, serious looking white male.

"Where the hell did you learn to tail someone?" Deeks asked.

" You should have known it was us." Sam reasoned.

"And how is that?"

"Our car." Callen answered simply.

"I couldn't make out the license plate because of the traffic." Deeks replied, his tone suggesting he was on his last straw and not to cross him today.

"Jeez man, did you miss your morning surf or something?' Sam asked. Deeks fixed him with a glare worthy of Hetty.

"Mind telling me why you were tailing me?" He asked angrily.

"Hetty's orders, she wanted to make sure you and your guests got home okay." Callen answered..

"Well isn't that dandy of her."

"Deeks, you nearly died cause you didn't alter your routine, picking up eight people in a huge black van makes you stand out and there was a high chance you could have been marked as an easy target." Sam reasoned.

"Wait I'm sorry, when did Potter nearly die?" Malfoy asked skeptically.

All three men turned to face him. They hadn't realized their conversation was being listened in on.

"Who's Potter?" Sam asked curiously.

"That's me…stupid nickname really, in school I was really into pottery." Deeks quickly saved. To his relief his classmates managed to keep a straight face though Callen had no qualms about laughing.

"You don't know about what happened?" Sam asked.

"I thought you kept in touch with your old classmates?"

"Um, not really, sort of always working wouldn't you say."

"Just tell me what happened my patience is waning." Malfoy demanded, his old pretentiousness coming out to play. Sam gave Deeks a look and Marty just shrugged his shoulders. He didn't really give a shit what they knew or not anymore.

"Out of the four of us, including our other teammate who's still doing paperwork, Deeks was the easiest target cause he didn't alter his daily routine; it wasn't necessary when he worked with LAPD. He was shot twice in the chest by a hit man hired to land him in the hospital as to lure the rest of us out. Once we figured this out Kensi came to Callen and I cause we were supposedly walking in on a trap but Deeks figured out it was Kensi who was the target and being the idiot that he was managed to get to the entrance of the hospital in time to shoot the bastard trying to kill Kensi and land himself in the hospital for an extra week." Sam finished.

Deeks was afraid to look at the expressions on the faces of his old classmates. When he looked up he saw disbelief on Draco and Michaels faces, admiration filled Cho, Padma, and Hannah's, and the rest were looking at him with surprise clearly visible on their face. None of them knew what a gun was but they surmised from the conversation that it was pretty dangerous.

"Listen, we've got a ton of paperwork to do, you can last a mile on your own can't you." Callen asked.

"Yeah, go ahead, I got it."

"Oh and Deeks, good job spotting us, next time I'll be driving." Callen yelled back. He heard a muffled sound of pain which he had a feeling came from Sam knocking him over.

He watched them pull out before turning back to his eight new roommates.

"What does he mean 'shot?" Cho asked.

"Um." How does someone explain this? Deeks pulled out his gun and removed a bullet from the barrel.

"This is a gun and this is a bullet. When someone pulls the trigger the bullet comes out of the end and it will go through a person and it can kill and seriously wound you depending on how many times you are shot, where, and what caliber the bullet was." He explained, pointing to his visuals and feeling all the more like one of his professors.

"What were you shot with?" Michael Corner asked.

"I was shot once in the abdomen and once in the upper chest with .22 caliber bullets, which is a pretty small gun." Deeks answered professionally.

"Does that hurt?" Dean asked unabashedly.

"Yeah, hurts like hell. Luckily they get you hopped on some great pain meds pretty quickly." He answered, a slight grin on his face as he remembered how he felt on those pills.

"Come on, we should get to my place before my boss sends out a protective detail, well another one."

"Your boss is pretty protective." Daphne Greengrass spoke up.

"Yeah, she's like a ninja, she'll pop up anywhere and everywhere at any time. Just wait you'll see." He added when he saw them look at him with that 'yeah right' face.

They all piled back into the van and made their way back onto the freeway. Only a half hour and already the three-ring circus had begun Deeks thought. Half-hour down, got knows how many more to go.
