Chapter Four: An Unexpected Visitor

A few days had passed since the day that Harry and Hermione started dating, the trio had been constantly busy and were still researching for clue that could help them in the battle against Voldemort. Harry and Hermione sometimes would have their moments when both of them would be in their little world and forget about Ron.

He didn't mind that but Hermione always feel a little guilty. It was Friday morning and she was already up, last night she had thought of an amazing idea and she was just waiting to see if it would work. She was making breakfast when she felt a pair of arms around her waist, she smiled, knowing already who it was.

"What are you doing up so early?" Hermione asked not looking at him.

"I couldn't sleep and I was sure that my lovely girlfriend was already up." Harry yawned.

Hermione turned around and kissed him on the cheek "I was up because I'm waiting for something."

"Something? What is it?" Harry asked.

"I can't tell you, it's a surprise. Now you'd better go and get ready – oh, and please wake Ron." She turns around and keeps cooking.

Harry didn't say anything and made his way to his room, before going to fetch Ron; who of course was still half asleep. Hermione rolled her eyes and took a seat, they ate their breakfast in silence; Hermione couldn't stop the smile that appeared on her face. Harry suspected that she was up to something while Ron, who was too busy trying to cram as much food in his mouth as possible, didn't even bother to try to find out.

After finishing their breakfast Harry and Ron went back to the library while Hermione was in the living room, watching the fireplace when suddenly the green flames appeared and someone came out. Hermione smiled.

"How was the trip?" Hermione asked with a smile.

"Not bad, I hate the floo network." The person answered.

"I know how that is." Hermione waved her wand and the person was cleaned. "Come with me, they are upstairs."

Harry and Ron were a little bored, they were tired of being kept researching and not finding anything that might help them.

"Hey guys, can I have your attention for a second?" Hermione asked.

Ron and Harry looked up at her with suspicious faces, as she usually didn't ask for attention.

"I know that we are all tired and we need some time to relax also I'm very aware that since Harry and I got together Ron has been feeling a little out," Ron looked at Harry and then at Hermione, the two boys were very confused so Hermione kept on explaining to them. "So I decided that we need some time to have some fun and I know that this isn't the ideal time for that but I invited someone to spend the weekend with us."

When Hermione finished saying that a blonde girl joined her, Ron was blushing while Harry was trying not to laugh by seeing his mate reaction. Hermione smiled, she knew that this was going to be great for Ron.

"I hope you guys don't mind that I invited Luna and I want everyone to have some fun this weekend, I know that is hard to forget what we are doing but we need to relax just a little." Hermione was smiling.

"Yes! It is nice to have you here Luna." Harry said.

"Thank you, I was very surprised when Hermione invited me but is good to be here." Luna said with a dreaming look.

"Is good to have you here Luna ummmm I'm sure that we are going to have fun." Ron managed to say while his ears turned a deep shade of red.

"Thanks Ronald, I was wondering if you could show me this place and of course where I'm going to sleep." The blond girl asked with a cheeky grin.

Harry smirked while Hermione giggled. Ron just nodded and got up. He took Luna on a tour of the house.

"And here is your room, the other one next to yours is Hermione's room." Ron explained while opening the door.

"Wow, this is huge and very pretty too. Thank you Ronald for been such a sweet guy and showing me around." Luna kissed his cheek and walked over to the window.

Ron blushed deep red, he knew that he been making a fool of himself since he saw her a few minutes ago, he didn't know why but she seemed to have some power over him. He was watching her while she was still looking outside, noticing how the sun was making her beautiful, long blond hair shine, he knew that he was staring at her but right then he didn't care, she looked like an angel.

Luna turned around and smiled sweetly at him before she walked over to him "Can we go to the living room?"

"Ummm sure, let's go." He said with a shy smile.

Luna giggled and linked her arm on his, while Ron ran his fingers through his red hair and started walking towards the living room. Harry and Hermione were still in the library relaxing. Harry's head lay in her lap as she caressed his hair gently.

"That was a great idea love, I'm sure that Ron is going to have a great time." Harry said with his eyes closed.

"I hope so; I've been feeling a little guilty since we have been putting Ron aside since we start dating."

"I know, but we didn't mean to do that." Harry was starting to fall asleep.

Hermione smiled and kept running her fingers through his hair, she knew that he was starting to relax and that soon enough he would be sleeping. In the living room Ron and Luna were talking a little, of course that Ron was still making a fool of himself but Luna didn't mind and thought that was funny.

"So ummm w-what you wanna do?" Ron asked not looking at her.

"What you guys usually do in here?"

"Not much, I think that you are going to be bored in here since we can't go outside that much and we don't have many things to do in this house." Ron looked at Luna and got lost in her dreamy eyes.

"I don't mind, anything is good for me as long I am with you." Luna looked at Ron with a sweet smile on her face.

Meanwhile back in the library Harry was lazily studying Hermione. Her lips moved, she was talking to him, but Harry couldn't hear a word she had said.

"Sorry". He smiled and then his smile turned into a fully fledged grin.

"Were you even listening to me?" Hermione asked

"No. Sorry, I was just thinking how cute you are," Harry replied.

"Honestly!" she sighed and then gave him a look that sat somewhere between exasperation and annoyance. Quickly she leaned to him and gave him a lightning quick kiss on the lips and pulled back before he could respond. "That was for the 'cute' bit." Then she just as quickly hit him over the head with the book she had open in front of her. "And THAT is for not paying attention."

Harry let out a "ow" and found himself laughing. "Tell me again then."

Hermione's eyes smiled "One more time Harry. I'll tell you ONE last time. And if you do don't pay attention this time I'll hit you with every book on the top shelf of that bookcase behind you."

Harry turned to see how many books she was talking about "THAT shelf?"

"Every book on it! Ready?"

Harry nodded.

"Good. I SAID if we want to know as much about Voldemort as possible, if we are going to find his weakness, then we are going to have to gather all the information we have on him."

"But there isn't any," Harry told her.

Hermione let out a sigh "No, not much. I admit that is going to be difficult. But the first thing we are going to have to do is somehow gather all the old Hogwarts school records. There HAS to be something in them to give us a clue."

Harry fell silent, considering this course of action. He looked around him to find the London National Library was not as busy as he had expected. They were in the secret (as far as the Muggle world knew) Magical annex to the National Library that housed the largest collection of magical books in the country. Perhaps the largest anywhere. They also housed all of the Hogwarts Old School Records.

A few wizards had walked through earlier but didn't stay long, and the only other occupant the large room had at this time was a very elderly witch that had fallen asleep in the comfortable chair with the book she had been reading still open on her lap.

Her glasses were slowly sliding down the bridge of her nose and almost falling from her face completely when as if by magic (because it probably WAS magic) they again very slowly crept back UP the bridge of her nose again. And then they would continue to make the trip up and down her nose, without ever falling off. Harry watched her glasses, not able to take his eyes off them. Finally Hermione saw that his attention had been drawn away from her, and turned her head to see what he was looking at.

Once Hermione saw the spectacles sliding down then up the unknown witches nose she turned to Harry "They're charmed."

"I know" he replied.

"Then why - - "

"Shhhh!" Harry stopped her before she could continue.

"Wha - -" was all she could say again before he had stopped her again.

"Say that again!" he implored her.

"What? The glasses?"

Harry nodded.

"About them being charmed?"

"That's IT!" Harry said loudly and quickly stood. He had a 'eureka' look on his face.

"What's it?"

"Charmed. That's IT! IF we can work out all the charms Voldermort has used in the past, then we can also find out which ones he doesn't use."

"How is that - - " Hermione was cut off again.

"Basic charms Mione. IF we find out which charms he doesn't use, or isn't proficient at, then we can use only those charms in some way to defeat him."

"How?"

"Basic charms. YOU should know that! What's the first thing you are taught about charms?"

She paused an instant and then could see his train of thought. "A proper defence to a charm can only be prepared when one is proficient at the charm in question."

"Right! So if we can get all the records on his charms, which ones he used and more importantly which ones he DIDN'T, then we can use those and only those ones to create an attack he shouldn't be able to defeat. Not easily anyway."

"But - - " Once more Harry had cut Hermione off.

"Ron's Dad told me the time all the best Aurors from the Ministry tried to attack him over 30 years ago. He said there were Avada Kedavra's and stunners flying every which way but he was able to deflect every single one."

"That makes sense," Hermione mused "He is probably better at the A/K than anyone else."

"And if he is so good at casting it, then he is equally good at defending himself from it."

Harry nodded and Hermione beamed. "Harry you are a GENIUS! It is perfect! The record of his marks at charms will still be on file."

Harry grinned and she grabbed him quickly around the neck and gave him a big kiss on the cheek. She turned and went to a row of books near the back of the room and started examining their covers as Harry joined her. After less than a minute Harry's patience had already ran out and he grabbed a book at random.

"Here," he said "Try this one."

Hermione looked at it "It's a bit early I think. I don't know if - - - "

"Let's go to the index and see if his name is listed. If not we'll try the next."

She gave Harry an odd look "Who taught you how to use an index Harry? That's not like you."

He laughed "Actually? It was you!"

She smiled and giggled as she opened the book. As she did a bolt of lightning exploded from the book's pages and hit Hermione with such force that it knocked her 30 feet into the air. Her body just as quickly fell to the hard stone floor with a sickening sound as her head fell hard and lay still on the floor, a searing smoking hole deep in the centre of her chest, where the lightning had struck. She was dead.

A scream was frozen solid in his throat, and couldn't escape.

Days and weeks flew past Harry like clouds on a windy day. He stood silent for most of them, not believing what had happened. He could not face her parents and wanted desperately to take their grief away. There were rivers of tears and so much crying as he explained what had happened, and even though everyone was saying he shouldn't blame himself, Harry could see and feel all eyes avoiding his own. They blamed him. She was dead and he had killed her.

He stood by her grave on a miserably cold and wet London winters day. Long, long after all the other mourners had departed and he still stood there. Even then, even weeks after, still not believing.

Ron had avoided him all this time. When he most needed a friend more than anything else in the world, Ron would have nothing to do with him. Ginny had told him, reluctantly, how Ron agreed that he had been responsible for her death.

The only single time Ron had spoken to him, was to remind him how he told Harry he wasn't to hurt her. and now he was (as far as Ron was concerned) responsible for her death.

He sat bolt upright in the couch, his head pounding and a scream was tearing at his ears; his own scream. He looked around, disoriented but briefly aware that it had been a dream, a nightmare.

Hermione entered the Black library, she saw Harry on the couch, he was sweating, so she ran to him and took a seat next to him, she didn't even have time to talk because the next thing she realised was Harry hugging her very tight. Hermione starts running her fingers throw his hair.

"What happened? I head you screaming." she asked not letting go of him.

He didn't knew if he could tell her, he was afraid of her reaction "Just a bad dream."

"Shhh, its ok we are in here and fine." Hermione kissed the top of his head

Slowly Harry let go of her, and looked into her beautiful brown eyes as he caressed her cheek "I love you and I'm not going to let anyone hurt you, ever."

Hermione didn't knew what to say when her eyes filled with tears. She kissed his forehead. "I love you too and I know you won't and if you want to talk about it you know that I'm here for you."

Harry hugged her again, he knew that he needed to do something to keep her and Ron safe, he knew that if they died he couldn't live with himself and this nightmare was the proof that maybe he needed to make them leave him – even though that would break his heart. He looked at her and kissed her sweetly on the lips; he loved her. He loved Ron like a brother and he needed to be sure that they were going to be safe.
