I own all of the books and movies… but alas… I do not own Harry Potter… Or NCIS.

Some background info:

This story begins right after Dumbledore is killed in HBP.

Also, I don't know the timelines, and I'm fairly certain that Gibbs doesn't reveal his age in NCIS, so just go with it if you think something is off about the NCIS side… and MI6 and any weapons used. This story is just for fun so if it's not completely accurate or the agents do something illegal… well it's not like everything they do in the TV series is exactly legal either right?

For the beginning of the story it is mostly going to be Harry Potter, at least for a few chapters, then it will start going toward NCIS and the rest of the story will mostly be NCIS. Just a warning since this first chapter doesn't have any NCIS at all

And with that… we begin

June 1997- After Dumbledore's funeral

If there was one thing Alastor Moody knew he was good at, besides capturing evil witches and wizards, it was observing those around him. A wizard doesn't become a top auror without constant vigilance and the ability to read people. He was using those skills currently, watching the boy-who-lived and coming to some not so startling conclusions.

Alastor Moody first met Harry Potter when he was rescued from his own trunk after the Crouch fiasco. Even though he was malnourished and neglected, Moody could see that Potter was a warrior. While the Diggory boy's death would haunt the boy, Potter fought back in that blasted graveyard and escaped with his life, going so far as to bring the other boy's body back so his parents could have closure.

The next time Moody met Potter was while rescuing the lad from his abominable relatives, while the young man was pointing his wand at his face and verifying his identity. It didn't escape Moody's notice that there were numerous locks on Potter's door, or a cat-flat, or even that while glancing around with his magical eye he could see evidence of Potter living in the downstairs cupboard. But still, after being raised in that home, the boy defended his detestable cousin from dementors, risking his own expulsion from the one place he felt he truly belonged.

Again Moody was impressed when he saw that Harry Potter was the only student left standing and able to fight at the Department of Mysteries the year before. A fight that could have been avoided if the boy had been given the information he needed. Instead, his old friend Albus Dumbledore wanted to keep Potter's innocence intact a bit longer and thus came the loss of the one parent Potter had ever known, his godfather, and Moody's friend, Sirius Black.

It seemed that every time Moody had met the young boy-who-lived, the lad showed his strength, his compassion, his need for justice. True, Harry Potter was a Gryffindor, but Moody couldn't help but think that he was also cunning in the way he handled many situations, including that blasted Skeeter woman and the minister's undersecretary Umbridge. McGonagall had reported her repeated use of a blood quill, and he himself had seen the scars on the back of Potter's hand, but the boy never complained. He had also heard about the effect of dementors on Potter and felt a stirring of pride in the young warrior for learning to stand up to the beasts instead of sinking into the despair that they brought in their path.

After all of this, it was no surprise to Moody the things he found while watching Harry Potter through Albus Dumbledore's funeral. He knew that Potter had been with Albus that night, as the second in command of the Order of the Phoenix; Albus was charged with reporting his whereabouts to Moody in case something went amiss.

Moody also knew that Potter had been having lessons with his old friend and that Dumbledore had charged the boy with a mission. With this knowledge, he could see by the way Potter was sitting that he felt guilty about his mentor's death, but he could also detect a bit of defiance and see that the boy was preparing mentally for something. He could only assume that Potter was going to try and go off to finish his mission for Dumbledore, but he knew he must catch the lad before he could leave. No matter how skilled Harry Potter had shown himself to be, he needed more training before he could even think about defeating Voldemort. With that thought in mind, the auror got out of his seat at the end of the funeral and followed the young man as he walked away.

He watched as the new minster, Scrimgeour spoke with Potter and walked away looking more than a little irritated. As he saw Granger and Weasley approaching, Mad-Eye made his move; he had to talk to Potter before he could run off with his friends.

"Potter!" the auror barked out to get his attention. He saw Potter stop and turn, waiting for Moody to catch up to him while waiving his friends away for the moment. Harry knew that if Moody wanted his attention it must be important.

"I know about Dumbledore's lessons with you Potter, and I know he was preparing you to defeat Voldemort. I don't expect you to come out and tell me exactly what the headmaster was working on with you; Dumbledore had a way with secrecy that would make a mute seem like a gossip. I do know that those lessons were not of the fighting variety and I want to make you an offer. You need training boy, and I'm willing to give it. I know you have a mission that you were given, but train with me through the summer and you'll be more prepared to face the battle that you know is coming." Moody waited for Potter's response to his offer.

Harry listened to Mad-Eye and had to admit that he wasn't prepared to face Voldemort. He knew he was a skilled fighter, but could he even beat an auror? Let alone an army of Death Eaters or their ruthless leader? He had told Dumbledore that he'd go back to his relatives for the last time this summer, but to train with Moody? That would help him on his mission immensely.

"Why didn't anyone offer to train me before?"

"Potter, you knew Dumbledore, you knew his propensity for keeping secrets, for not telling you anything about your own life, and you knew his mistakes in not telling you the prophecy. Do you really think he would allow someone to train you for combat and ruin your chance at a normal childhood? He was convinced you weren't ready yet and that you'd be ready for this type of training when you were out of Hogwarts. I'd like to think I've observed your character enough to know that you want to end this before more people are killed. So do you want combat training or do you want to go on your mission and hope to Merlin you survive intact. I can tell you right now that the chances of you, Weasley, and Granger all coming through this war intact without one of you having specialized training is slim to none."

Knowing that Moody spoke the truth, Harry only had one more question before he agreed.

"I told Dumbledore that I'd stay with my relatives this summer for a last time. Is that going to be a problem?"

Moody almost laughed at this question and gave his honest opinion. "Potter, Dumbledore wanted you to stay with your relatives because he set up blood wards tied to your aunt, have you ever felt loved, ever felt like that house was home?" As Potter's head shook in the negative he continued, "Bill Weasley is an extremely gifted curse-breaker and warder and we've had this discussion many times. You see, blood wards depend on the relationship between the two involved; they also depend on whether or not you consider the house to be home. Blood wards are a very personal thing, and your aunt hates you, and you hate her more or less. I don't see why the blood wards would still be intact, and Bill agrees with me. So in answer to your question, you'll be staying at Grimmauld Place where we'll put up a new Fidelius since Snape knows the secret."

Harry was gaping by the time Moody's explanation was through, it made sense though. In all of Dumbledore's scheming and planning, he neglected to see that Harry was truly unhappy in his relative's home, so intent was he to protect the boy; he missed the glaringly obvious signs of abuse and malcontent at the house. Harry made up his mind and finally answered the old auror.

"When do we leave?"

"Why don't you tell Granger and Weasley that you'll be at headquarters this summer and not to worry. I believe Bill has a wedding planned for later this summer so tell them you'll see them there. I need to set up the training schedule and then we can meet at King's Cross when the train gets in tomorrow." Moody said while thinking through the training possibilities. He'd have to contact some old friends and see if his idea would work.

Feeling that the conversation had gone on long enough in front of the people milling around, Moody took his leave and left Harry to say his goodbyes and pack up.
