A/N. Thank you @jessicaauburn for being a fantastic beta!

Harry rolled onto his back, stretching out his muscles and yawning loudly. He rubbed sleep from his eye and made a move to sit up only to find someone blond pop up from somewhere out of view.

"Harry!" The voice exclaimed with.... Was that worry or relief?
Harry reached for his glasses, and once they were settled on the bridge of his nose he smiled up at the familiar blond.
"Good morning Draco, umm why are looking at me like that?" Harry asked confused. Draco was staring at him, his brow creased slightly and he had his thinking face on. He stepped close and for some strange reason Harry couldn't comprehend took Harry's hand in his own. He was about to ask why when Narcissa appeared in the doorway and Harry realised that Draco wasn't holding his hand, he was taking his pulse.
"Um, what's going on?" Harry asked.

But no one gave him an answer, instead he got an answer in the form of another question.

"How are you feeling honey?" Narcassia asked, and Harry felt himself go pink at the pet name.

"Fine? Great actually. Why, what happened?" Harry asked, now more confused than ever.

Narcassia took a seat beside Harry and then told him what had happened the night prior.

"Oh," Harry said after she was done. That would explain why they were worried.
"Has any magical item been in your bloodstream recently? That's the only explanations I could come up with, though it would have to be very powerful if it got this far."
Harry thought, well it wasn't like he would stick magical items into an open wound or anyth... Oh wait. The prophecy.
"Do you think a prophecy would do that? I broke one in my hand about a week ago."
Narcassia looked immediately focused.
"Yes. Oh Harry I'm so glad you're all right," she said and Harry frowned in ever yet more confusion.
"What do you mean? It must happen to loads of people."
"It doesn't, and when it does, which is very rarely, one of three things happens: You get poisoned, you get weak or you get stronger. Though cases of survival are rare and-" Narcissa said but was interrupted.

"Wait. I could have died?" Harry asked disbelieving.

"Well you see a prophecy, especially an important prophecy, holds very powerful magic and when it enters the bloodstream of a witch or wizard it tries to bond with their magical signature. Sometimes their magic will repel so viciously that the person is poisoned or weakened to the point of all magic dissolving completely. But in special cases they join together and... well let's just say you're very powerful now."
Harry stared at her, he took a deep breath and tried to let what she had just said sink in.
"When you say more powerful what exactly do you mean?" He asked, amusing himself with the image of a magical ripped six pack.
"Well you can show us, here try and levitate this glass."
Harry made a move to get his wand but was stopped. "Without a wand."
Harry frowned, he had tried wandless magic before and failed abysmally. But nevertheless he brought out his hand and fixed his eyes on the glass sitting on the black bedside table. 'Wengardiumleviosa' he thought as he imagined the magic coursing towards the glass and then..the glass glided gently into the air. He dropped his hand, startled, and the glass fell onto the floor, the water spilling out onto the dusty floor.

He found out later that he did not have a magical ripped six pack much to his disappointment.

It turned out that a spell cast by his wand amplified the magic and well, let's just say that glass he was trying to repair shattered. And that made no sense whatsoever, so Harry had to make a mental note to tone down the strength of any spell, jinx or curse which was strange to say the least. Harry found himself casting all sorts of spells with ease and he didn't quite know if he liked being this powerful but this could give him a better chance when fighting Voldemort, though he still reckoned he needed all the luck he could get anyways.

By the end of that day a new room had been cleaned, dusted and livable but Harry didn't move room, he enjoyed having Draco warm against him and having soft breaths cascade his neck when he awoke. That night Draco held him a bit tighter than usual and Harry knew he was still awake because his breathing wasn't quite the same as it was when he fell asleep.
"Harry?" He heard Draco ask softly into his neck. Harry hummed in response.

He felt Draco shift, the old mattress springs creaking as he did so. Then Harry felt a leg shifting over his right hip and then the comfortable warm weight of Draco sitting on his stomach. Harry smiled up at him, through the gap in the curtain moonlight filtered though and made Draco's hair look more silver than Harry had ever seen. Then Draco was leaning down, his hand tugging though Harry's black curls, Harry could feel his warm breath ghost his lips, they stayed there for a second, hovering, and Harry could feel the intense right through to the tips of his toes. He almost couldn't breathe with how gentle Draco was, his hand now moving down to cup his jaw lightly and rub a thumb gently in circles on his cheek. But he didn't kiss Harry yet, instead he mummerd "I'm so glad you're still alive, I don't know what I would do if you had died."

Harry sucked in a breath but he didn't have time to respond because now Draco was kissing him softly, the touch so light it took Harry's breath away. It was so slow, so gentle and so intense. Harry tilted his head deepening the kiss and Harry felt warm from his head to his toes and he never wanted Draco to leave because truth be told he wouldn't know what to do if Draco died. After what felt like a blissful eternity they parted and Draco rested his forehead against Harry's. Silence fell around them again but it was a calm silence, it was a silence where both of them didn't quite know how to put down how they felt at that moment into words.

"I wouldn't know what I would do without you Draco. I would die inside if anything happened to you," Harry managed to whisper. They fell asleep that night, with Draco sprawled out on top of Harry, his head tucked under Harry's chin and Harry's arms holding him close to his heartbeat.

That day McGonagall visited, she was greeted at the door by Narcissa at the 'early' time of eleven.

"Ah, Professor McGonagall, to what do I owe the pleasure?" She asked holding open the door and inviting her in.
"I just came to check on the house, and to make sure Harry hasn't gotten into any trouble," McGonagall replied with a hint of a tease at the end.
"Oh well, best to have a cup of tea then I would get Harry down here but he and Draco are still sleeping," Narcissa said, pulling out some China tea cups with thin, delicate handles and setting the kettle up.

"You see McGonagall, Harry had...I'm not sure how to say this. It was a magical fit I suppose, no don't worry he's fine, but it turned out that a prophesy had been broken, entered his bloodstream and joined his magic with the magic from the Prophesy."
McGonagall was quiet and after a few minutes she spoke.
"So his magic had increased? What of the side effects?"
Narcissa poured tea into each teacup, with one sugar each and a slash of milk - making the dark liquid swirl turning a soft caramel colour.
"That's the issue, it is so rare for an incident like this to occur that no one really knows what happens or what side effects there are, if any at all. Biscuit?"

"Yes please, I expect you will keep me informed of these things and owl me of any changes," McGonagall said while sipping on her tea, she put it down slowly onto the ornated saucer and looked at Narcissa carefully.
"I need you to take care of him, I can tell you care and he has said he trusts you...I know things are difficult but I want you to promise me that you will help us if you can."
Narcissa put down her own cup. She knew what this meant. It meant switching sides, it meant fighting for them. She didn't belong to anyone at present, running away from the Death Eaters meant she didn't belong there any more but did she ever want to be? She had been brought up to think it was good, her sister Bellatrix always talked about how proud it would make their parents but now her husband was dead and Draco and herself were in danger.

"Can you provide Draco and I with protection?" She asked, her voice surprisingly steady even though her heart felt the opposite.
McGonagall set a hand upon hers and squeezed it lightly.
"We will protect you and your son" she stated simply and that was all Narcissa needed.

"Okay. I will stand by you and I will fight by you."

McGonagall smiled warmly at her and released her hand.

"Thank you Narcissa, I really am sorry for your loss. We really need someone like you. Thank you for the tea and I hope to see you again soon," McGonagall said sincerely.

One thing was clear, Draco would be safe, and that's all Narcissa needed.
