I'm soo sorry for the huge update delay! I'm trying to start again : Next part :

"Whoaa," said Ron, holding up his hands, "Slow down! We can't just rush into conclusions like this. How do we know that Regulus was the author?

"Well for one thing, he scribbled his name all over the notebook," said Ginny.

"That could've been a girl's notebook," suggested Hermione. "Someone who might've liked him?"

"I don't think so," said Ginny. "The notebook has the same exact handwriting as the yearbook with the words 'Property of Regulus Black'. Plus, Regulus wasn't exactly attractive."

Harry remained silent, deep in thought.

"Harry?" said Ginny, poking him in the arm, "Are you okay? You look a little lost."

"I think we should contact Remus," said Harry. "We need to know everything about this Regulus Black. Sirius never told me much about his brother."

Ginny nodded. "I agree. Remus is the only alive Marauder we can trust. We definitely do not want to go crying to Peter Pettigrew."

"Well...okay," said Hermione, her eyes worrism. "But I don't think we should send him a letter. With attacks going on around the school, we don't know what might happen."

"That's fine," said Harry, grinning. "All we need is some Floo Powder."

"Okay, cool," said Hermione sarcastically, "Anyone got any?"

"Professor Snape does," said Ginny. "I noticed it when I had detention in his office last year."

"Okay," said Harry mindlessly, "We'll just sneak in Professor Snape's office, and iborrow/i some Floo Powder."

"Cool," said Ron, "I'm coming too, right?"

"Of course," said Ginny, "We're all coming. We shouldn't let Harry go alone."

Hermione groaned. "I must be out of my mind." She gathered up Regulus' books and the Ghost book and stored them in her bag. "Okay, when are we doing this? Tonight?

"When Snape is out of his office," said Harry. "Our best bet is around five o'clock, that's when he does detention."

"Okay," said Ginny. "We'll meet in the Common Room around 4:30."

Harry couldn't concentrate at all during Quidditch Practice that day. He was nervous about visiting Number Twelve, Grimmauld Place again. The last time he was there was right after Sirius died. The Order still held meetings there, which gave Harry the idea that Remus would be staying there.

All of a sudden, Harry was nearly knocked off his broom by a rocketing Bludger. Ron, who was guarding the posts bursted out laughing.

"Concentrate, Harry!" Ginny yelled, zooming by him. As she approached, she said in a quieter voice, "I'm nervous about Grimmauld Place too." She gave him a warm smile, which froze Harry completely, and took off to get the Quaffle. Harry was left, frozen in the air, and couldn't even budge when the Snitch brushed against his nose.

"You're bringing the Invisibility Cloak, right?" Hermione asked Harry nervously when they all met in front of the fireplace.

"Yeah," said Harry, holding it up, "But I don't think it's going to cover everyone."

"Don't worry," said Hermione, "Ron and I are prefects, so it'll look perfectly natural if we're walking down the halls. You and Ginny should cover up though."

Harry's arm hairs stood on end as Ginny covered him and herself with the Invisibility and made sure that they were fully hidden.

"Okay, guys, just follow us," Hermione said, and she opened the portrait door.

Hermione and Ron bid the Fat Lady a good evening, and they walked down the hallways towards Snape's office, with Ginny and Harry following them.

They finally reached Snape's ugly office, with Harry tripping over the Invisibility Cloak a few times. Hermione looked around, tapped the door knob with her wand and muttered, "Alohamora." The door creaked open easily.

"Okay, c'mon, guys," Hermione whispered, and she and Ron entered the room, Ginny and Harry following, careful to keep their feet hidden.

"Good, it's empty," announced Ron, walking around Snape's cold and slimy office. "And, look! It's the fireplace." He hurried over to a fireplace, with a pot of Floo Powder on top of the mantel.

"Excellent," Harry said as he finished folding the Invisibility Cloak, and joined Ron in front of the fireplace.

"Harry should be the one to talk to Remus," Hermione said. "Ron, Ginny, and I will stand guard."

Ron and Ginny nodded at the idea, and so Harry grabbed a handful of Floo Powder and threw it into the fireplace. It exploded with green flames.

Being careful not to inhale in any smoke, Harry yelled out clearly, "Number 12, Grimmauld Place!" And flung his head into the fire. Harry immediately closed his eyes the moment his face met the licking flames - Floo Powder was still not his all-time favorite way to get from place to place. Especially when it's only his head that's traveling.

"Harry?"

Harry opened his eyes to see a confused Remus Lupin staring down at him from the kitchen table.

"Hey," coughed Harry.

"What are you doing?"

"Well, I have a question for you," Harry said.

"Okay, shoot."

"How well do you know Regulus Black?" Harry blurted out. Remus started at him like he was crazy.

"Before I say anything, may I ask iwhy/i you're so suddenly interested in Sirius' brother?"

"Oh, come on, Remus, you know that Regulus was the author of Love or Not," Harry said quickly. He wasn't sure how long he was going to get to talk to Remus.

Remus closed his eyes slowly and rubbed his temples. Harry stared at him intently. Finally, Remus opened his eyes again and knelt down in front of Harry to see him better.

"To start off, you must know that even though Regulus turned out to be as dark as Voldemort, he was very bright. He was respectful. If someone asked him to do something, he would do it. He kept promises. And he was ivery/i obedient. However, he was also a little nosy bugger. He liked to know about things that weren't any of his business."

"So...? What's your point?" Harry asked hurriedly.

Remus paused to get in a more comfortable position on the floor and continued. "Well, that's how Regulus found out about your mom and Sirius's relationship. He spied on them throughout their relationship and was so fascinated, he wrote a whole story on it, shielding the names."

Harry listened silently. There was an itch on his nose, but he couldn't get it. He twitched and his glasses slipped down his nose.

"Sirius had found out about his brother's secret play, and asked for him never to show it again. Being loyal as he was, Regulus kept his promise. This play was hidden in the school library. Until now."

Harry, who was attempting to push his glasses back up his nose without the use of his hands, paused. "So, Regulus is back. As a spirit. He's trying to stop the play to keep Sirius's reputation."

Remus ran his hand through his hair. "Harry -"

But, before Remus could say anything else, Harry felt a strong yank, and his head slipped from the fireplace. He found himself coughing on the floor of Snape's office.

He looked up to see Hermione and Ginny holding onto his shoes.

"Hurry! Under the Invisibility Cloak," Hermione gasped. "Someone's coming - we have to get out of here." Ginny and Harry hastily threw the Invisibility Cloak over themselves, and Hermione and Ron slipped out of the office with Ginny and Harry behind them.

They continued to walk down the hallways. It wasn't long when they encountered Filch and Mrs. Norris.

"Good evening," Filch leered.

"Prefect duties," Ron blurted, and Filch nodded cooly before continuing on his way. Mrs. Norris, however, hesitated before following, her yellow eyes staring straight into Harry's.

"That cat is not normal," Harry said quickly the moment they were out of ear-shot.

"Shh!" Hermione snapped, and they continued on their way to the Fat Lady's portrait.
