"Maybe you were" Harry said but he didn't really believe that "but it still doesn't change the fact that I've not permitted you to address me so informally, you are the Chief Warlock, it wouldn't be good for you to forget your etiquette so please refer to me as Mr Potter from now on."
"Ah" Dumbledore's smile dropped for a split second before he brought it back "if you insist, Mr Potter."
"I do insist" Harry said
"I was wondering how you are handling your classes?" Dumbledore said as if he hadn't heard Harry
"I believe I'm doing well" Harry replied "the teachers seem impressed and I am enjoying myself. Though I am curious, why me?"
"I beg your pardon Mr Potter?"
"Why have I been brought to your office and why are you enquiring about my classes? As far as I'm aware I haven't gotten into any trouble or done anything worth being sent up to the headmasters office"
"Worry not Mr Potter" Dumbledore waved his hand "you are not in trouble, that was merely me trying to make conversation. The real reason I've called you up here is to ask a few questions, the first of which is have you met your brother yet?" He gestured to Adrian who looked at him.
"We've met" Adrian said "but I think there has been a misunderstanding sir"
"What misunderstanding are you talking about?" Dumbledore asked
"My brother can't be a Slytherin" Adrian said "the sorting hat must have made a mistake, he should be resorted and put into Gryffindor" Snape wanted to say something but was cut off by Harry.
"No thank you, I'm fine in Slytherin"
"But why?! Why on earth would you want to be a Slytherin?"
"We get our own rooms" Harry answered with a shrug of his shoulders "besides, I have no problems with Slytherin's so I don't really see the deal."
"Mr Potter, surely you would like to join your brother in Gryffindor?" Dumbledore asked "I'm sure it would make your parents proud"
"If my parents were anything like people described then they would be proud no matter what house I was in"
"I can't believe it" Adrian said "my brother, a slimy snake"
"Snakes aren't slimy, they're actually quite smooth" Harry pointed out
"Whatever" Adrian replied "So, where were you all these years?"
"Home, what about you?"
"I was living with Dumbledore" He said proudly, forgetting that Harry hadn't really answered the question.
"In the castle?" Harry asked
"No, I lived in one of his houses. The house elves raised me"
"So you he left you there?"
"No! He'd visit every once in a while"
"What magic has he taught you?" Harry asked Adrian, who didn't respond "He hasn't taught you any magic?!"
"No, but like I need it, I'm the boy-who-lived. I don't need half the amount of training others do, besides, Dumbledore has gave me loads of money and got me all the best brooms"
"How kind of him" Harry said sarcastically
"What's your problem?!"
"I have several, do you need a specific one?"
"Mr Potter" Dumbledore interrupted "I would've thought that you would've been happy, seeing your brother after all of your years apart"
"I was" Harry said "but from what I've seen of him, I doubt mother and father would be very proud of him"
"You what?!" Adrian clenched his fist
"Father may have been a little arrogant when he was younger but he didn't go parading around like he was Merlin's gift to wizard kind" Harry replied "most of his arrogance could be earned, he was brilliant in school despite all of his messing around. He worked hard, so did mum, since I've met you you've done nothing but prance around like a peacock and demand respect. You don't even try in class"
"I saved the world from Voldemort!"
"Did you? Maybe mum defeated him and died in the process? You ever think of that? Or maybe mother or father did something to you that stopped the curse? Or maybe you just happened to be a one in a million fluke, the only witnesses to the actual event not including our parents were you, me and Voldemort. I doubt you defeated him through sheer will or power"
"You're just jealous" Adrian shouted
"Jealous?" Harry looked amused "jealous of a boy who relishes fame he received for something that he doesn't remember? Are you always this intelligent or is this just for me?"
Adrian had enough and charged at Harry, who simply leaned back and extended his foot. Adrian tripped and fell over, landing on his face.
