Once Harry made his way out of the King's Cross Station he meditated on where he should go next. Taxis constantly stopped at the King's Cross Station entrance, dropping off passengers and picking them up. If Harry wanted to go somewhere, he could just catch one there. The only question was, where did Harry want to go?

The Dursleys lived in Surrey, about 30 miles away. Sirius' old house, Number 12 Grimmauld Place, was only a few miles away from King's Cross. Harry decided to head there first. Even if he couldn't make it past the fidelius charm, there had to be some way to communicate with the wizards living inside.

Harry hailed a taxi to take him to Sirius' residence. It took several tries with his child body, but eventually he managed to grab a taxi cab driver's attention by jumping up and down and waving his arms in the air.

Unfortunately, the cab driver had never heard of Grimmauld Place.

Shortly thereafter the cab driver learned that Harry didn't have any money on him and Harry was unceremoniously evicted from the cab.

Harry tried walking to Grimmauld Place, but none of the streets he followed took him where he wanted to go. Harry even stopped in a few corner shops to see if anybody could point him in the right direction.

Nobody could help him, and some of the people he asked gave him some very strange looks.

With no better plans, Harry started wandering the streets of London until he could find something familiar or useful.

Harry walked down a street that looked like it connected to the street one block over, but actually ran into a dead-end. It was not the first time that day he made that mistake, but as he turned around to retrace his steps, he saw a teenager approaching him.

"Lose your way?"

Something about the teenager set alarm bells ringing in Harry's head. Harry fingered his wand, even though he knew he would be unable to cast any spells to defend himself.

"Yes. I'm a bit lost," Harry said. "I'm looking for Number 12 Grimmauld Place. Do you know where that is?"

The teenager ignored Harry's question and continued to close the distance between them.

"What's that you're wearing?" he asked. "Think you're some kind of priest?"

Up until that point, Harry had completely forgotten he was still wearing his school robes. The funny looks from earlier made more sense now.

"No, I just got back from school," Harry replied.

The teenager pulled a large knife out of his back pocket.

"Well, you picked the wrong place to get lost," he said. "This is my turf, and I don't take kindly to trash like you squatting here."

"I just want to go home."

"Yeah," the teen said, "maybe you'll go home in a body bag. Maybe the police'll find your body. Or maybe," he said, extending the knife straight at Harry, "you'll just give me everything you've got."

Harry had been afraid, but now anger flared up inside of him. Ever since his first encounter with the altered reality, nothing had made any sense. He had been bewildered, frightened, and left feeling like he had had no control over the life around him.

And now this arrogant punk wanted to mug him?

No. Harry had enough of being pushed around. It didn't matter that Harry had nothing of value. It didn't matter that Harry was now in a very dangerous situation. All that mattered was that Harry refused to be pushed around any more.

Harry glared at the teenager, adjusted his body language to be as intimidating as an eleven year old boy could possibly be, and said, "Piss off."

The teenager didn't like that at all. As soon as the words left Harry's mouth the teenager swung his blade at Harry. Acting on reflex, Harry waved his wand and shouted "Expelliarmus!"

A bolt of red light burst from Harry's wand and hit the teenager. The teenager was knocked backwards, the knife flying out of his hand and landing on the ground behind Harry.

Harry stared wide-eyed at his wand, stunned by his own actions. He had just cast a spell! Harry laughed before realizing that the teenager wasn't as stunned by this turn of events as Harry was. In fact, the youth was launching himself at Harry again!

Harry cast a quick stunning spell. The teenager collapsed to the ground, his forward momentum nullified.

Harry laughed with joy for a long time after that, casting spell after spell for the sheer joy of it. Wingardium Leviosa on a nearby rock to levitate it. Finite to cancel the spell. A summoner to bring the rock to him, then a banisher to knock it away.

Harry giggled giddily.

Harry looked at the prone figure on the ground. Now what was that spell to create ropes? Oh yes.
"Incarcerous!"
Thick looking ropes appeared out of nowhere to bind the stranger.
"Aguamenti!"
A jet of water hit the bound teen, waking him. He sputtered and coughed.

Harry asked, "Now then, do I have your attention?"

The teenager moved to attack Harry, but the ropes prevented him from doing much more than bunny-hopping or falling over. He thrashed to get free, but the bonds held tight.

"Argh! You let me go! I'll," and here the youth spewed forth language that was both offensive and anatomically unlikely.
Harry interrupted, "Silencio!"

The youth continued yelling silent profanities. When he realized that he couldn't make any noise he doubled his efforts and turned quite red in the face.

"You threatened me with a knife," Harry said. "You could have killed me, and I don't think you would have cared too much if you had."
Harry picked up the knife. "This knife, in fact."
Harry placed the tip of the knife just under the thug's chin.
"So tell me," Harry said quietly, "what do you think I should do with you?"

The teen paled as he realized he was now at the mercy of the very person he'd tried to mug just minutes before.

"You're just lucky I'm a better person than you," Harry said. "Stupefy."
The youth slumped to the ground, unconscious.

Harry took stock of his situation. Now that Harry could cast spells again, what did he want to do?

Two hours later Harry was checked into a very expensive five-star hotel under the name of Ludo Bagman, courtesy of a few well-placed confundus charms.
