Last Time

"Percy, who is he? Why does he look so familiar?"

Sirius seemed to be hiding a smile, "Harry, I'm sorry, but we really should be going to dinner. I'd tell you now, but I really don't think I'm the best person for the job, perhaps Remus, Harry-"

"Who is he, Sirius?"

Sirius sighed, his lips twitching as he smiled. "Harry, you have to understand, and keep an open mind, we really-"

"Sirius, who is he?

Sirius sighed again, before saying the words that would change the life time of Harry Potter forever.

"Percy's your brother, Harry."

Chapter 10

"What?"

His godfathers words echoed in his head, Percy's your brother, Percy's your brother, Percy's your brother, until eventually they became only one word; brother. Harry had a brother.

When Harry had seen the boy, he had thought that he looked familiar, that the boy looked a younger him, but he had never actually thought that he could really-, he had thought it was his mind playing tricks on him, that it was his simple need for a family, finally, getting to him. He had never thought that it could actually be true-

He had a brother.

He, Harry Potter-, Harry James Potter, had a younger brother.

He had a family.

Harry managed to stutter out a simple, "How?" interrupting his godfather's rambling. When he saw the smile that started to appear on his godfather's face, he cut him off again. "I don't need the birds and the bees talk, Sirius, I just want to know how. How is he alive? Why are we only finding him now? Why didn't you tell me?"

Sirius collapsed against the wall behind him, watching Harry with strangely mature eyes. "I think you know why we didn't tell you, Harry. We didn't want to cause you anymore pain."

"Yeah, obviously," Harry muttered to himself. Part of him wanted to be angry at the man in front of him, for keeping such a secret to himself. Such a big one, which Harry had so deserved to know. But he understood Sirius, and all the others, for surely Sirius hadn't been alone in knowing this, for keeping this to themselves. "But-"

"Harry, you've been through a lot, I know that. Don't think for a second I don't realise you deserved to know, but we thought he was dead. You aren't exactly known for making wise decisions, and we didn't want you to put yourself in danger, looking for revenge. I thought for years that Voldemort was a monster for killing James and Lily, but he was in a even higher category for killing a baby. Can you honestly tell me you might not have gone out of your way to avenge him?"

Harry didn't reply, his words frozen in his mouth. Sirius was right, he might not have gone out of his way to find Voldemort, but that didn't mean that he wouldn't of made more rash decisions when he was already facing. One more straw on the camel's back, and what a big, or rather small, straw it was. When he found Sirius' eyes still cautiously watching him, he nodded, sitting on a bed behind him. Sirius nodded back at him, before continuing.

"Percy was just over two weeks when Voldemort attacked; it's a miracle he was born at all, really. He was premature, you see, he was born on the 18th. We're not sure yet-"

Sirius' speaking was interrupted yet again, this time by the door swinging open to reveal a red haired witch brandishing a wand, who breathed a sigh of relief upon seeing them.

"Oh Harry dear, you really should be getting down to dinner," Molly Weasley said, tension seeming to leave her body, "You too, Sirius. You know how it is, unless you get down there soon, it'll all be gone."

"Of course Molly," Sirius said, standing up. "I don't suppose you could save a bit for both of us? I was just explaining the Percy, Perseus that is, situation to Harry here."

The red head's eyes widened, her eyes softening as she took in Harry, before hardening as she started at Sirius, "I was under the impression you were going to wait until after dinner."

Sirius smiled at both Molly and Harry, "Harry here was demanding to know who Percy was."

"Oh, of course. He does look quite like you, doesn't he, Harry dear? Of course I'll save food for you. Do you want me to send Percy up? I doubt he'll be able to eat properly with you two up here. There's no doubt he'll be knowing what you're talking about, and he doesn't like all the loud noise at dinner anyway-"

"I'm sure if Harry has no problem with Percy coming up here to talk," Sirius said, grinning at Harry, who quickly nodded his consent before properly thinking the offer over, "As long as Percy has no problem with coming, I doubt either of us has a problem with it."

"Well then," Mrs Weasley beamed at Harry, "I should go save you some food then. Harry dear, good luck."

Unless Harry was mistaken, he heard a sniffle as the door quickly closed behind the witch, but his attention was hardly on the Weasley, but rather on his own thoughts.

He was about to meet his brother.

He had, of a sort, met him earlier, but the time they most spent staring at each other could hardly be called a proper greeting.

Was he ready to meet his brother, Harry wondered, after all he had only discovered the boy's existence a few minutes ago. Surely people normally in these situations had more time to sort themselves out first? Was he even ready to be a brother?

That question shocked Harry, as he was struck once again by the realization that he had a brother, but not only that, but that he was a brother. Perhaps he should ask Ron for advice. Or many there was a 'How To Brother' guide out there somewhere. Whatever time Harry had to question this realization, and where he could get his hands on a guide, was short though, as he was pulled from his thoughts by Mrs Weasley's laughter.

It was a few seconds after that that the door opened, and Percy walked in.

If Harry had been expecting his impression of Percy's appearance to change upon seeing him for the first time, and actually knowing he was his brother, but nothing happened. He was still the same; dark hair (similar to his own, though not as out of control), green eyes (the same as his and the mother he barely remembered), and half a head shorter (like he had not yet gone through a growth spurt, like the growth spurt Harry just had).

"You didn't take long, Percy," Sirius smiled, "Have you learned to apparate?"

The boy's, Harry's brother, eyes flicked to Harry and back to Sirius before softly speaking, "I followed Mrs Weasley up, I was near the stairs waiting for you."

"Well then, that's nice..." Despite Sirius' confidence before Percy had appeared, now he seemed unsure, eyes glancing between the two brothers. Eventually, he huffed and continued, "I have no idea what to say here, so if one of you could have a little bit of motivation, it would be appreciated."

Harry snorted, before standing and brushing invisible dust off his jeans, and offering his hand to Percy, "I'm Harry."

Percy's eyes skittered over Harry, taking in his appearance, before Harry started to mentally panic. What if he was judging his clothes, Harry stressed, before, what right does he have to judge my clothes. Perhaps Harry would of driven himself into a deeper state of stress if Percy hadn't reached to shake his hand, grinning slightly as he did so.

"Yeah, funnily enough I know. I'm Percy."

Harry felt his ears burn, before replying, "Yeah, funnily enough, I know."

Percy grinned at him, and him and Harry felt himself relaxing. Perhaps this wouldn't be so hard after.

"Well then," Sirius decided, "That was cringe worthy to watch. I'll just leave you two to get to know each other. I'll be back in a sec, I'll just go make sure Molly kept her promise to save us some food, cause I'm absolutely starved."

With that, Sirius left the room, ignoring both brother's echoes of 'wait'.

Which left Harry alone with his brother and an awkward silence.

Ok, in all seriousness I wanted to continue, but my wifi is really emotional, and it's about to die any minute now and I'm not sure when I'm going to be able to post again, but hopefully soon, so I figured I might as well post what I have.

Also guys, I'm also going to be writing a side story, which is just basically set in the same universe, but are just basically unconnected oneshots, like where Ron and Hermione meet Percy, or where they find Percy in Prisoner Of Azkaban instead. Things like that though, because they're all in my head, and I need to write them down so I may as well post them, so you can get a better idea of this world.

Thanks, and please review
