"The Power The Dark Lord Knows Not"

To say Albus Dumbledore was nervous, would be to making an understatement.

In addition to this note written in Harry Potter's handwriting, delivered to him this beautiful morning by an equally beautiful Hedwig, was a single vial filled with an all-too-familiar silvery-blue liquid.

A memory.

But of what, Albus could only wonder.

But that wasn't why he was nervous. Well… actually it was. Not only was he worried about how young Harry had managed to extract the memory, the boy not having the knowledge nor equipment to do so, but he was also worried about the fact that Harry had apparently discovered the 'Power the Dark Lord Knows Not' on his own.

That was one of the reasons Albus was hesitant to watch the memory Harry had sent to him. There were only so many ways that he could imagine Harry's ability to love being presented, and the last thing he wanted to see was the boy he'd come to see as a grandson engaging in a ritual of a sexual nature in order to destroy Voldemort. Of course, it could also be any number of the various love-powered spells out there, but since none of them were combat spells – instead being some of the world's strongest healing magicks – he doubted that they'd be of any use to Harry in a duel.

As Fawkes let out an assuring trill, Albus smiled gratefully in the direction of the phoenix, before uncorking the vial and tipping it out into the pensieve before him. Reaching into his drawer before he entered the memory, he ensured he had his favourite muggle spiral pad and fluffy pen before diving right in, hoping he wouldn't need to cover his eyes or scramble to leave the memory.

Except his first impression told him to do exactly that. It was only his mind finally catching up to his eyes that stopped Albus from fleeing the memory until he could build up the courage to watch it. So yes, while there was an alarming amount of flesh on display, it was only because young Harry was lounging on a hot sandy beach in a pair of muggle shorts, and not because his honorary grandson was engaging in any inappropriate acts. Actually, now that Albus thought about it, this hardly looked like any beach he knew of, there weren't any beaches in England that had those lovely little Hawaiian flower necklace things were there?

It was the sight of the resort in the background, and the other tourists all sunbathing on the beach that made Albus' jaw drop. How had Harry gotten past the watchers he had in place at Privet Drive without any of them warning him?

"Hey, Headmaster," Harry greeted suddenly, the boy lifting his head to look at exactly the space Albus was standing – so Harry did know what he was doing, only someone who knew would set an entry point like this. "Greetings from Hawaii. This place is lovely, amazing beaches, hours worth of sun, beautiful women. Sure, it's a little more expensive than I thought it would be, but I'm rich, so who cares?" Harry said with a shrug, reaching out a hand to catch the can of muggle soda that appeared out of nowhere. "Anyway, I'm sure you're wondering how I got here -" at this Albus nodded, before remembering with a start that this was a memory "- and how I knew what to do in order to make this memory".

As Albus nodded again, scowling at himself for a moment, he watched as Harry stretched and sat up. "The answer is pretty simple, you'll figure it out soon, I'm sure".

With that, Harry Potter shot Albus a cheeky grin before vanishing with only a soft rumble to mark his passing, the Headmaster remaining in the memory for just a split second more before he was being kicked out of the memory as it ran out.

Gasping as he tried to regain his breath – there was a reason he hated viewing memories till the end in a pensieve – it took him longer than he'd admit to notice that the chair opposite his desk had been moved around it and a small stack of books sat on it with another memory vial. "Fawkes," he began, not needing to finish the sentence as the phoenix cooed sadly and shook his head, apparently not having seen Harry – for who else could it be – moving everything into place.

Sighing, Albus did the only thing he could, which was add this new memory to the pensieve after removing the first, before diving right back in.

"So I guess you know by now am I right?" Harry asked, Albus watched as the boy zipped up a pair of jeans and buttoned up his shirt. "I mean, you know what the power is right? How else could I have gotten into your office and out again without using your door?"

The blasted boy was right, Albus realised with a combination of both impression and annoyance washing through him. Harry had, somehow, managed to bypass Hogwarts' wards before apparating into his office under his invisibility cloak. That also meant that the boy had some way of seeing into his office so he knew when Albus was in the memory.

It was then that he noticed what was wrong, Harry had just been on Hawaii, so why was the Eiffel Tower visible from the window? There was no way that Harry had gotten from Hawaii to France using apparition, the amount of power that far of a distance would take would tire even Albus out, especially since the only other way for Harry to have done it was to take muggle transportation which was even more unlikely.

"An illusion?" he asked himself thoughtfully as he obediently followed Harry from the room, shuddering each time he walked past someone in the crowded hallway. It was a very elaborate one if that were true, but what else could it be? An illusion would explain both the movement in his office and the movement in locations. But if Harry had learned to apparate at age fifteen, something he fully believed the boy capable of, would it not be possible for Harry to have 'filmed' these memories at two different times?

"So I'm not going to even pretend to understand how your mind works," Harry began as they found themselves in an empty alleyway, "But I'm going to tell you this, which I'm sure you'll have no troubles understanding alright? I will be going back to Hogwarts next year. But if you search for me, if you try force me back to the Dursleys, then you'll never see me again," he promised simply, the look in Harry's eyes telling Albus that the boy was deadly serious. "I'm going to have some fun this summer, I'm going to enjoy myself, and then – only if you're good – I'll come back in time for Hogwarts to start, and I'll play nice okay? I think if anyone deserves a vacation, then it's me, yeah?"

"Oh, ad just to prove that I'm being utterly serious," Harry added, "Watch".

And with that Harry was gone, five feet to the right. And then he was beside Albus, then he was in the mouth of the alley, and then he was back to where he had been initially – the only sign he'd moved at all being the soft rumbling sounds that followed.

"You won't be able to catch me Albus, the moment I catch sight of you or your little Order of the Phoenix, I can be on the other side of the world in a heartbeat," Harry warned, "Don't test me. You won't like it when the results come back in".

Albus didn't even get the chance to think before he was being kicked out of the rather short memory, quickly adjusting to the need to breath again as he shook his head rapidly. What was he going to do? Did he just sit back and let Harry run around doing what he wanted? Or did he put his foot down and stop this childish behaviour?

No…

It didn't matter what Albus did. Harry was right, what he'd been doing wasn't apparition, meaning it likely couldn't be traced. And even if it could, if Harry can get across the world in the blink of an eye then what could he or the Order do to stop him? Even if they stunned him and brought him back, he'd just leave again.

No. He'd let Harry have this holiday of his, the boy would need it. Albus planned on beginning his training next year, and he'd need all the joy he could get.

A soft rumble tore through the air, disturbing naught but the lone early-rising bird peaking at the ground for worms. Seconds later, Harry Potter was standing on the hillside, watching the bird fly off into the sunset like in a bad romance novel.

Humming to himself, Harry looked around for a moment before pulling his backpack up higher onto his shoulder, turning to face the castle he could see in the distance. Taking a step forward, it only took one more rumble before his foot was setting down on the stone floor of the Hogwarts entrance hall, the boy glancing around with a fond smile on his face.

God he'd missed this place. None of the other castles he'd seen on his journey were anything like this one, and none of the places he'd stayed in even came close to Hogwarts.

Barely making it to the staircase, Harry was gone again, reappearing in his dormitory to find four occupied beds and one – his – unoccupied bed. "How nice," he murmured to himself upon seeing his trunk waiting at the end of his bed, knowing already that it was mostly empty with only the things he didn't want left in it. Dumping his bag on the bed, Harry quickly changed into his Hogwarts uniform – which he'd left in his trunk – and emptied the backpack out onto his bed. A flick of his wand had the clothes quickly floating into his trunk, folding themselves neatly, while another flick had his school books sorting themselves into alphabetical order beside the clothes. The remains of his backpack however, were looked upon with joy, as Harry set an unmoving muggle photo on his bedside table before placing everything else into a small shoebox-sized chest which was shrunk and hung around his neck.

Letting out a pleased noise as he realised he was already ready for his day, Harry pocketed his wand, teleporting a book to his hand with a snap of his fingers before he was turning on his heel and leaving the room.

"Harry! Is Harry back yet?" Hermione blurted instantly upon seeing him descending the stairs, "Professor Dumbledore said he'd be back last night but he- HARRY!"

Grinning as he allowed Hermione to throw herself at him, Harry hugged her back. "Hey Hermione," he greeted happily, keeping the two of them moving, "How was your summer?"

"How was my summer? How was yours?" his bushy-haired friend demanded, "You ran away!"

"No I didn't, the Dursleys gave me permission to leave," he corrected simply, promptly earning an unimpressed look from Hermione.

"I hardly think the Dursleys count as parental figures, meaning their permission counts for nothing," she denied, "You should have asked the Headmaster," she scolded.

"Why? He's my Headmaster, not my Dad," Harry dismissed, smiling innocently at his friend whose scowl couldn't stay on her face for long, instead making him throw an arm over her shoulder as he led her towards the door. "I needed to get away, Hermione," he added seriously, lowering his voice so it was only them, "And Professor Dumbledore wanted me locked up, so I couldn't ask him. I was fine, I was safe," he insisted as Hermione opened her mouth to argue, "I used protection every single time – that's a joke – and yes, I made sure I did my homework".

Hermione rolled her eyes at him for that, "As if I care about homework when Voldemort could have killed you at any moment," she hissed, making Harry snort in amusement.

"How could he kill me, Hermione?" he asked simply, releasing his grip on her shoulders, "When I can do this?"

And with that, Harry turned and sat down at the Gryffindor table in the Great Hall, leaving Hermione standing in the common room in utter shock.

SUMMER HOLIDAYS

So this is a second response to my own 'Jump' challenge, it's better and completely different to the first one, in that Harry actually went to Hogwarts in this one and has every intention on having some fun before taking out Voldemort, while in the first one he didn't even believe in magic.

The Undercover Ninja definitely doesn't own Harry Potter.
