[A/N]: Hello! Thank you for taking the time to stop and give this fic a chance. It's a rather outlandish idea, but I thought it would be fun to play with considering the characters of NCIS are so unique. I spent a long time reading the HP Wikias and looking up spells to try and be as accurate as I can, but really, I've taken a lot of creative liberties with this one. I'm not sure how long I plan for this to go on. Most likely around mid season 3, as I would like to introduce Ziva at some point, as well. The first few chapters will mainly focus on introducing the characters in this different universe.

As for point of view, I intended for this fic to be written from Kate's perspective, but McGee was just so easy to write. I may switch it around between the three (Tony, Kate and Tim) in later chapters. With that said, I hope you enjoy and please leave a comment if you can. Thank you! - BB

Chapter One

Shark Bait

"Keep up, McGee."

"Sorry, sir."

"Don't call me 'sir', McGee. It's Gibbs or 'Boss'," the man informed him bluntly before taking a sip of his coffee.

Tim rushed to follow his quick strides, "Sorry, sir – I mean – Uh, Boss." The two entered the elevator and Tim winced at how much he was fumbling with his words. Great, first day on the job and he was already screwing it up.

He just couldn't help it. When he applied for the Auror position, he hadn't been expecting much. It was common knowledge that the selection process for the job was very meticulous and the chances that one of the Senior Aurors would take interest in a new recruit were slim. The last known addition to the Auror Office had been four years ago with a woman named Caitlin Todd, but even then, she had an advantage from the start after transferring from protection detail of the President of the Magical Congress.

Five years ago, Tim would have never dreamed that he would be an Auror (well, Auror in training), and really, he had never envisioned himself working for the government, let alone the Magical Congress. He was a half-blood, as his father had been a wizard and his mother a muggle. He hadn't even known about magic until he had received a letter from the Flumine Academy of Magic in Washington D.C. stating that he was accepted into their school. During those years, magic had been the best and worst thing that has ever happened to him. The charms and spells were fun, but the pranks and bullying were ten times worse than they were in muggle schools. To this day, Tim still felt nauseous when he saw slugs.

It hadn't been all bad, though. He had passed his OWLs and NEWTs with flying colors, earning 'Exceeds Expectations' in most subjects and even an 'Outstanding' in a few others. Not only was he a good student when it came to magic, but he worked very well with muggle technology. The Head of the Auror Office, Director Morrow, had even stated that part of the reason why he had been accepted over other candidates was due to his experiences in the muggle world.

But despite his knowledge and what he liked to consider competence, he did fall a bit weak in one specific category: Defense Against the Dark Arts.

He had received an 'Exceeds Expectations' on his NEWTs , so it wasn't that he was uneducated in the subject, but more along the lines of that he was… lacking, in a sense. Tim understood theories and methods without any problems, but it was the dueling that he needed guidance with. He was hoping that now that he was in training, Gibbs would be willing to show him a few pointers.

Or maybe not, Tim thought with another glance at his new boss, feeling strangely intimidated.

One other thing that had surprised him with this job was that he was not going to be just any Auror, but part of the Magical Crime Response Team.

Headed by Senior Advisory Auror Leroy Gibbs, the MCRT was meant to be the 'on call' group that dealt with the more investigative side of the job. While other teams targeted larger scale, notorious dark wizards, their team was meant to catch the smaller threats before they became larger problems for the community. In simpler terms, they were wizard cops, which was exciting and a bit frightening on its own, especially for a man like Tim McGee, whose previous job entailed fixing and working on computers.

The elevator dinged and a disembodied female voice announced, "West Wing, 3-B, Magical Case Response Team."

Gibbs did not even wait for the voice to finish, and squeezed out of the elevator as soon as the double doors opened, leaving Tim to rush after him. The pair turned the corner and passed a few random doors before they arrived at the main office area. And while Gibbs did not hesitate to head towards his desk, the younger man stopped and took a moment to look around in awe at the sheer amount of magic in the room.

The room was painted a bright orange color, but he then noticed that the shade was slowly shifting into a brighter hue, mimicking the early morning sky outside the window. When he glanced up, the ceiling was absent, leaving a dark void in its place. He assumed that this was the reason why the room was lit with orbs of light instead, some large and stationary, while smaller ones hovered above the desks. Papers sat suspended above the desks and when Gibbs reached his chair, Tim watched as a few documents made their way over to him.

The silver-haired man plucked them from the air sharply, "Kate, is this John Huggan's background check?"

Out of the corner of his eye, Tim saw a woman turn towards Gibbs, "Yes, he's a forty-five-year-old Caucasian male, half-blood, went to school outside of the states and moved here when he was twenty-three. He is currently unemployed and married to Jennifer Huggan." After her report, the woman, whom he assumed was 'Kate', sent Tim a cursory glance before she looked back down at her work.

"DiNozzo, how's he related to our vic?" Gibbs asked while his eyes never left the papers in front of him.

The man seated behind the desk opposite of Kate's leaned back in his chair and began to explain his findings, "Well, their relationship is definitely weird. It's like if Kate and I were to get married –."

"DiNozzo."

"Right. Sorry, Boss. Ducky's confirmed that our Jane Doe is actually Jennifer Huggan, age thirty-eight, and she's a Squib," DiNozzo also looked over at Tim, but instead, a smirk spread across his face and he raised a brow towards Kate's direction, who simply rolled her eyes at the gesture.

Gibbs finally raised his head from his desk to speak to DiNozzo directly, "You tellin' me that our vic was John Huggan's wife?"

"Yes," the other Auror started. "And according to Abby, his sister as well."

The room was quiet for a few seconds until Gibbs rose from his chair and muttered, "I need coffee." Gibbs strode back out of the office with his now seemingly empty styrofoam cup.

"Um, Boss?" DiNozzo piped up and pointed to Tim. "What about –?"

"Introduce yourself, McGee," was all Gibbs said before going back into the elevator, leaving Tim alone with the two other Aurors.

Squib - A non-magical being, born into a wizarding family. They are often looked down upon by the wizarding community.

President of the Magical Congress - Like the Minister of Magic, the President of the Magical Congress heads the American wizarding government, not to be mistaken as the President of the United States.

Magical Congress - The United States' wizarding government.

Flumine Academy of Magic - A wizarding school that I took the liberty to create. 'flumine' quite literally means 'by the river' in Latin.
