Dumbledore knocked on the door, "Mr. Riddle?"

He waited a few moments. Remus Lupin and Sirius Black standing beside him, both had a hand ready on their wands, waiting for the grandson of Voldemort to open the door and possibly attack them.

Dumbledore knocked again. "Mr. Salazar Riddle?"

The door was opened partially, stopped by a rusty chain connecting the door and the door frame. Half of a sixteen year old face peeked out.

Dumbledore was slightly taken aback, 'His looks are almost identical to those of his grandfather, but it's always the eyes.'

"First of all, what the fuck kind of name is Salazar Riddle? Second of all, wrong apartment. This is the Jackson's, and I'm Percy, Percy Jackson."

Sirius' eyes widened slightly. So it's true, he thought, The Jackson line is still alive. With Riddle, Jackson, and Slytherin ties, he will either be a huge asset, or our worst enemy.

"My name is Albus Dumbledore and I-"

The door slammed shut.

"Mr. Riddle, we only ask that you let us speak to you." The wand was all the way out now. Dumbledore started casting spells to check if any magic had been used earlier, malicious or not.

"I am not Salazar Riddle. I'll tell you what I told the other guys. I don't know who you are, why you want me, what I have to do with you and your fucked up world."

Lupin took Dumbledore's place at the door. "Percy, my name is Remus Lupin, I knew your mother Sally Jackson."

"Then you would know not to fucking talk to me!" The door flew open all the way.

Remus was shocked into a step back, surprised that his bluff worked. "I-I'm sorry, I didn't know it would hurt this much. Has something happened to her?"

"Happened to her? Oh, no, nothing's wrong. She's just dead." Percy scoffed, moving to close the door again but Remus put his hand on it.

"Percy, you said that you'll tell what you told to the other guys to us. Who were the other guys?"

"Some people that offered my to join them. They were called, what was it, oh yeah! They called themselves Death Eaters. One of them was the leader and called himself Voldemort."

Dumbledore stepped forward, "Mr. Riddle."

"That's not my name. I don't care who you think I am, but I am Percy Jackson. And if you don't think that's who I am, you can fuck off."

"I apologize, Mr. Jackson," Dumbledore's eyes twinkled. "What I need to know is did you accept their offer?"

"What if I did? They warned me you were a manipulative old sot, how am I supposed to know who I can trust?" Percy crossed his arms, eyes blazing with fury. "That's why I am staying out of this mess. Wizards are not my thing."

"I must say I disagree, I never drink. After all, I am in charge of a couple hundred children. What surprises me is that Voldemort did not kill you, even though you are a Half Blood." Dumbledore said, referring to his supposedly muggle father and Pure-blood mother.

"H-how did you know I'm a Half Blood, what does that matter?" Percy, however, was referring to his godly heritage.

"Voldemort is trying to purge the world of Half Bloods and Muggleborns."

"What if they haven't done anything?" Percy's stance changed completely, it went from aggressive to protective. Remus could tell he Percy was a compassionate boy, even though Percy know naught of any Muggleborns himself, he felt protective of people horribly wronged. "Are all wizards prejudiced bastards like him?"

"No, they aren't." Remus jumped in. "When you were about six, do you remember meeting a man named Tom Riddle? He looked a lot like you and tried to kidnap you from school."

"Um, yes, and you know this how?" Percy's stance shifted from being protective of others to being protective of himself.

"First, may we come in?" Dumbledore gestured to the apartment.

"No. You may not." Percy stepped outside into the hall and closed the door before either of the men could see inside.

"Alrighty then, we shall go to 12 Grimmauld Place."

"Where is that?" Percy asked, "it's nowhere in New York."

"No, it's in London."

"How do you suggest we get there? I'm not flying." Percy scoffed.

"We apparate." Dumbledore stated as though it were obvious. "Snuffles, do put a paw on Mr. Jackson here, Remus, you apparate with them and I shall apparate after you once I put some wards us around Mr. Jackson's apartment."

"No, I don't want you doing stuff to my apartment." Percy shook his head.

"Then we can apparate away after, I shall explain every spell he casts and what he does." Remus shot Dumbledore a look saying Do everything we need to to get him to trust us.
