A/N: sorry for the delay, I was visiting family the whole week. This story is set at the beginning of book six, though there may be small things that do not match. I have read the seventh book but the story will not touch on that for a while. Hope you all like the story (I made some general assumptions on the Doctor's side to blend the two series). Please read and review.

Doctors and Portkeys

Chapter Two: Magical Coincidence

A soft whir filled the streets of London as citizens of the great British city passed by a run down set of stairs leading to an uninviting lavatory, so little care cast that not a soul noticed the sudden appearance of a blue call box in the small alley.

Even less attention given to the three figures that emerged from the police box, whom of which look rather peculiar on second glance. The man obviously in charge looked to his companions with a bright smile.

"Here we are lady and gent, the ministry of magic." He said with a flourish indicating the lavatory below.

"Not very impressive looking" The dark woman in leather said taking in the dirty stairs.

"Why did you bring us here?" The second companion asked. "I don't exactly have the best track record with the ministry."

"Oh nonsense Harry, everything will be fine." Their eccentric leader said leading them down the stair. "The new minister set up this entrance to protect against death eaters." The doctor indicated the coin slot where a key hole should have been. Taking out his favourite tool, he pointed the metal cylinder at the coin slot, which clanked, and the door swung open. Inside they found a disgusting looking set of toilets.

Harry stepped up to one of the toilets and mimicked the Doctor as he stepped into the bowl. To Harry's surprise his foot passed right through the water to stand on a hidden platform. With a grin that matched that of the Doctor, Harry pulled on the overhead chain and disappeared in a flash of green.

Tumbling out of an ornate fireplace Harry stood and joined the Doctor as he and Martha walked through the vast atrium. It had not been long since Harry had faced off with Voldemort in that very same room. The memories were still fresh on his mind. The look of dread on his godfather's face as his body slipped into the veil. Harry had to shut his eyes hard to keep the tears from returning.

"Doctor you said that you knew my parents." Harry said trying to clear his mind of bad thoughts.

"That's correct, I was in the order once." The Doctor replied smiling at Harry through his brown frames. "That was a long time ago, a different lifetime." The Doctor and Martha shared a glance that Harry failed to notice.

"Why haven't I ever seen the two of you at order meetings before?" The boy who lived wondered. The Doctor seemed like a very powerful wizard and Harry could not help but think that they could have really used his help.

"After the death of your parents I abandoned my stay on earth." The Gallifreyan answered. The Doctor's eyes glazed over as he remembered his past. "This was the last place Susan and I were before leaving."

"Who's Susan Doctor?" Martha asked as they stood in the busy atrium next to the ornate golden fountains.

"She was my granddaughter, the first person on Gallifrey I brought to this world." The Doctor seemed less sad as his focus came back to them. "She was nearly ready for the trials of the time lords."

Harry had been operating thus far on the notion that the Doctor was from a remote nation of wizards. He was however losing faith in his suspicion the more the Doctor spoke.

"Come now we need to pick some things up from my office." The Doctor said leading the three to a set of golden elevators.

"Oi, where do you lot think you're going." I burly wizard demanded blocking their path.

The Doctor pulled out two pieces of psychic paper, which to the guard looked like two warrant cards. Each had a picture of either the Doctor or Martha. "I'm Chief Inspector Smith and this is Inspector Jones." The Doctor said merrily.

The guard looked form the papers to the Doctor and his companion. Finally deciding that the papers looked real enough he turned his gaze upon Harry. "He's going to have to turn in his wand."

"To bad he isn't going to." The Doctor answered. Pocketing his warrant cards the Doctor reached his hand out to Harry. "Give me your wand."

Not sure what to do Harry handed the Doctor his wand which was then placed in the same pocket as the warrant cards. Seeming to be satisfied the guard returned to his post leaving the three to enter the elevator.

Harry looked above him to see the familiar sight of paper airplanes floating in the overhead of the compartment. Each tiny message got of at its respective floor as the trio continued up. Getting off on the floor for Magical Law Enforcement, the Doctor, Harry and Martha walked down a hall containing individual offices. Harry recognized the name of Amelia Bones on one of the doors they passed. One of the middle office doors had caution tape across its frame. The plate next to the door read:

Chief Inspector Smith

High Warlock of the Wizengamot

Order of Merlin, First Class, for Arithmancy and the Dark Arts

"This is your office Doctor?" Harry asked. The door's surface had collected so much dust that it covered the door like a film.

"Haven't used this in quite a while," The Time Lord said pulling out his sonic screwdriver from his pocket. In less than a moment, the door was open and the caution tape dissolved away.

As they stepped into the office, Harry began coughing along side Martha. The amount of dust told Harry that the Doctor had not been here for several years.

"Doctor, your name plate says you're a master of the dark arts." Harry asked once the dust had settled.

"Yes Harry" The Doctor answered while rummaging around on his desk and upturning more dust in the process. "In order to defeat the forces of darkness you must first understand them."

The answer made sense to Harry, in fact even though his friends never quite agreed; Harry had always felt that the only way to defeat the Dark Lord was to understand whom Tom Riddle really is.

Exclaiming loudly the Doctor pulled a long cylinder from one of the many shelves. It looked to Harry like a wand.

"What is that Doctor?" Harry asked.

"This Harry is a Sonic Spanner, it emits an ultra high frequency which used by a wizard allows one to cast Arithmancy much faster than when using a wand." The Doctor said handing it to Harry.

"Isn't that what your sonic screwdriver does?" Martha asked.

"Yes well it took me a long time to figure out how to miniaturize it." He said. "I wanted you to have it Harry."

Harry moved the object through his fingers thinking of how jealous Hermione would be. "That's great Doctor." Harry said a smile on his face. The device did in fact look a lot like the doctors sonic screwdriver. The spanner was about thirteen inches long with a smooth exterior save for a set of tiny dials that were inlayed into the handle. One end was blunt with another dial and the other end tapered like a wand with a red plastic tip that reminded Harry of an LED light.

"You've not mastered Arithmancy so its best you didn't rely on it for everyday spells until you have." The Doctor said. "I think that's all I needed from here." He said making one more pass with his eyes. "Alright we need to go."

The Doctor walked out of his office and resealed its entrance once they were all out. The two companions where led back to the same elevator that they had to share with several wizards one of which Harry recognized as Mr. Weasley.

"Harry what are you doing here?" Mr. Weasley asked just as the doors were closing.

"Ah, how are you Arthur?" the Doctor questioned with his trademark grin.

Arthur Weasley seemed confused for a moment until the Doctor flashed his warrant card.

"Doctor" Arthur muttered only half asking. It had been a long time since Arthur Weasley had seen the Time Lord last. Back in the days of the first war against Voldemort the Doctor had looked middle aged with what Arthur had always though was normal muggle fashion sense. The Doctor was ever wearing his ten-foot multi-coloured scarf and mismatched overcoat and trousers. The Doctor before him however was no older than thirty years old and wore a stylish thin three-piece suit. "My have you changed Doctor."

"Do you like the new look?" The Doctor asked.

"Simply smashing" Was all Arthur could think of. It was a minute before he remembered that Harry was there. "You're in good hands Harry." He said clapping the Doctor on the shoulder.

The elevator opened and Arthur walked off the lift with them. "Why don't you join us for dinner?" Mr. Weasley asked.

"Love to." The Doctor said watching Mr. Weasley disapparate.

The Doctor and his companions made their way back to the fireplaces and, after having to explain how they worked to Martha, returned to the lavatory above.

The trio emerged from the rundown lavatory racing up the stairs. As Harry ran into the TARDIS, he could not help the smile that burst onto his face.

"So Doctor, where to next?" Harry exclaimed excitedly as he gripped the centre consol ready for action.

The Doctor grinned at his two companions as he pumped a lever on the consol. "Wherever the TARDIS leads young Potter wherever she leads."
