Disclaimer: I do not own Harry Potter, or else I wouldn't be writing here.

First of all, sorry for that loooong hiatus, school kept me very busy, and then I had writer´s block (kind of), so… yeah. Anyway, I'm back and that's the important thing, right? This is the last chapter (finally), but there will be an epilogue (REALLY?), in which everything will be explained (even the doubts that will surge from this capter), I promise.

He had a terrible headache, he felt dizzy and confused. What had happened? Oh right, she had stunned him. Great. He oppened his eyes, but he couldn't see anything. At first he thought he hadn't opened his eyes at all, but then he realized everything was too dark to see. Where was he?

As if on cue to answer his unasked question, a brilliant silver light bathed his surroundings, allowing him to find out where he was. It was the astronomy tower, and the moon was responsible for the sudden ilumination. Apparently, some really black clouds had been covering it and that's why he hadn't been able to see before.

"I see you've finally woken up" said a familiar voice hidden in the shadows "I was starting to think you would never do it"

"Why are you doing this? What do you want?" he asked impatiently

"Now, take it easy, we have time" she said in this extremely calm voice "And don't try anything funny, remember I have your wand" she added as an afterthought

"Who are you and why are you doing this to my friend?"

"You really don't know? I thought you would have it figured it out by now. I guess I overestimated you" she said in a teasing voice

"Answer the question" he all but growled

"Don't tell me you don't remember me, after all, I killed Sirius Black" she said the last part in a singsong voice

He was taken aback. How had he not noticed before? The spirit that was trying to possess his best friend was… Bellatrix Lestrange. But how could it be possible?

"Surprised?" she asked mockingly "Well, I guess it's normal, you all thought that I was gone just because you killed me, but I'm not that easy to get rid of"

"But… how?"

"I refused to die, but I didn't want to become a ghost. That would be useless, don't you think? I really wanted, no, needed to come back to life, but since that is impossible, I became a spirit. Spirits aren't alive, but they can possess someone, and that is pretty close to being alive"

"Why do you want to be alive? It's pointless. Your Lord is death, and all his minions are either locked away in Azkaban or hiding like the cowards they are. It's all over. We won."

"Oh, but this isn't over yet, and it won't be until I say so. I made a promise to my Lord, and I'll keep my word. I will never give up, not even death can stop me. I won't be happy until my Lord's wishes become reality, until the world is cleaned from all that scum you call muggles, and their child."

"And why did you choose to possess a mudblood then?"

"But my vessel isn't just any mudblood, is your mudblood, and unless you are very dim, I think you know why I did this. Or should I spell it out for you? I wanted REVENGE"

"So you did all this for me? You shouldn't have bothered" he said with bitter sarcasm

"You think I don't know what you feel for her? It's too obvious, even a muggle can see it. I know where to hit so I can hurt you the most"

And as she said that, the clouds covered the moon again, leaving them in the shadows. He heard some faint footsteps heading towards him, and her now velvethy voice enveloped him with her next words:

"This ends now, and what better place than where we started?"

As sudden as the clouds had appeared, they were gone, and everything became clear again. He was finally able to see her. She was still wearing her white robes from St. Heathsburg, but she looked really mad with his wand in her left hand and a knife in the right one, which he had no idea of where she had gotten it. Why was she so obsessed with knives, anyway?

But there was something wrong, she looked confused. When she looked at him in the eye, she seemed surprised.

"Harry?" she asked with her normal voice.

She was back. Apparently, Bellatrix only showed up when it was dark. He quickly stood up and tried to run towards her. He grabbed her shoulders for reasurance, wheter it was for her or for himself, he wasn't sure.

"Harry, help me. Please, make it stop" she put her hands (wand and knife included) in her head "She's taking control, I c-can't keep her out" their gazes locked, there were tears in her eyes "She's everywhere"

"Don't worry, we'll find a way soon. Right now we need to get out of here" he tried to pull her so they could leave, but she resisted.

"No! You don't get it, I need it now! She'll be back, and she may not leave anymore"

"But Hermione, I don't know how to get rid of her. Look, let's go now and I'll search in the library day and night, there will be an answer, I promise"

"Books don't have all the answers. If there was one there, you would've found it by now, don't you think?"

"Have some faith. There MUST be a way"

"You have no idea of how to fix this. But you're right, there is a way…" she lowered her arms and grabbed his, making him stop holding her. She took his hands and put the knife on them. He inmediately understood what she was trying to tell him.

"Do it. We both know it's the only way"

"No, no,no" he remarked his words by shaking his head from side to side "I WON'T DO IT"

"You have to"

She grabbed his hand that was holding the knife and guided him until the knife stabbed her heart. He watched in horror as blood started pouring out from the wound. She slumped and he caught her in his arms. He lowered them both to the ground and watched life slowly abandon her eyes.

When she released her last breath, he took out the knife that was still in her chest. He hadn't noticed he was crying and mumbling her name. He gently closed her eyes and left her on the floor.

He stood up, knife still in hand. The knife he had used to kill her. He fisted his hair with his other hand while he let his emotions consume him. His best friend, the person he loved the most was dead, and it was all his fault. Not only he had turned her into a target, he had also caused her death. He looked at the red knife, disgusted with himself. He wasn't a killer, or at least hadn't been until mere moments ago. He had killed a person, he had killed the girl he loved. The guilt was overwhelming. He didn't deserve to keep living. He looked at the banister and without giving it any second thought, he went towards it and crossed over it. He spared a last glance to his best friend's corpse and jumped. He had comitted suicide.

He hadn't noticed that the blood pooled around the corpse was slowly going back to were it came out from. It returned to her heart, which started beating again once all the blood had been reabsored and the wound had been healed. But the beating belonged to someone different from the person who had died.

Not once had her earlier words crossed his mind, for everything would have been different if they had: "I need to die so she can live…"
