A/N: It's me again! No! Don't run away! Good! Now stay! That's better. Just so you know, this is the last chapter.

Disclaimer: Harry potter isn't mine. I have never claimed ownership to it anyway.

Chapter nine -

I looked at Harry for a moment. It wasn't natural for a child to be that quiet, especially not a 16 year old boy (A/N: I know from experience with my brother). He should have been full of life, happy, noisy, like any teenager.

"Harry, I-" I started, but was cut off. The mark - it was burning.

I let out a hiss of pain, drawing his attention.

"Pro- Severus, what's the matter?" he asked, sounding slightly afraid, as though he expected to be hit, though his voice was still relatively bold. Some people never change completely.

"It's okay," I managed to gasp out. "He's calling me!"

With that, I left the room quickly and got my mask. I needed to get there quickly. If I didn't I would be in for another of the Dark Lord's little 'lessons'. I really didn't want to have to go through that.

I apparated to where Voldemort summoned us, just outside Privet Drive. The pain in my arm resided quickly as I arrived, and I went through the usual bowing and such before Voldemort started up.

"My faithful Death Eaters, tonight is the night I finally rid myself that of bothersome brat, Potter! Kill any you like, but Potter is mine."

He emphasised the last words, as if to make sure that none of us would touch him. We wouldn't anyway. Even those that are truly loyal to him wouldn't. Everyone knew what would happen if anyone hurt him before Voldemort got a chance.

I set off, trying to cause as little damage as possible, not wanting harm anyone, though, of course, I had to do something to prevent the Dark Lord's suspicions.

"Incindio," I said, pointing my wand at a bush. It burst into flame, and I moved on to something else.

I could hear the other Death Eaters killing and torturing the muggles. I used to be like them. Fortunately I manage to reform myself. Though there was one muggle I wouldn't say no to torturing.

For the next 10 minutes I carried on burning plants and the like, until I made one discovery that would make my day. Vernon Dursley.

Even thinking about it now I can't stop the smile that comes to my face. I know I shouldn't have enjoyed torturing him, but after what he had done to Harry, his own nephew, I couldn't help it.

I had found him hiding, cowering behind some muggle rubbish bins. At first I didn't recognise him, foolish of me really, and I was going to tell him to get out of there, but I remembered then remembered what he had looked like, his build at least, from Harry's memories, and I could feel my face spread into a gleeful smile.

"Dursley," I said, making him turn around. This was going to be fun.

I saw him go white when he saw me, and turn to run.

"Petrificus Totalus!" I yelled, casting the full-body bind on him, knowing full well it would only make it more painful for him without the ability to scream. "You're not going anywhere, Dursley."

I could see his eyes dart around fearfully, as if hoping, by some miracle, that he would find some way out of this situation.

Realising I wanted to hear his screams, I bound him with some ropes that I quickly summoned, and then ended the petrificus.

Raising my wand, I knew that revenge would be sweet. Sure, a lot of the curses I use on him could send me to Azkaban, but the thought of revenge on that fat muggle instantly dismissed all thoughts of the consequences.

I can still list the names of the curses and hexes I used that night on him. The cruciatus, incindio, waterma, which put out the flames, the skin tearing curse, the bat bogey hex, the Conjunctivis and the Blood Boiler to name but a few, though I didn't use the Killing Curse. No, the other curses I used on him caused him so much pain that he died before I had a chance to. His screams still stick with me and give me joy to this day, as will the fact that they may never be able remove his blood from the ground.

You may call me evil, to enjoy another mans suffering at my own hands without feeling remorse, but you must remember what this man has done. He may not be on the same scale of evil or darkness as the Dark Lord, but in some ways he is evil, there is no doubt.

He had beaten, neglected, starved and goodness knows what else his own nephew, along with killing his own wife and son, before taking off, leaving Harry chained to a bed to starve.

He had also returned to the place where he had committed such heinous crimes against his own flesh and blood, for reason we may never know the reasons of. But I believe he had gone back, probably to finished Harry off if I hadn't of take him out of that place only a matter of days earlier. Knowing how a murderer often thinks (one of the many downsides of working for the Dark Lord) he would then have probably of disposed of the body the same way he had done for the rest of his family.

I could go on for hours about this, I know I could. It's very easy to. Surprisingly easy to in fact. But I'm sure you don't want to hear about that, so I will go on to the rest of the attack.

After the Dark Lord had discovered that Harry wasn't there, which was just after I'd finished torturing Dursley, we all got out of there quickly. He gave us each a short dose of the cruciatus and then dismissed us. It was a small price to pay, really. After all, I had got the revenge I had wanted so much. And there I go again, talking about my revenge on Dursley. I had better stop that before you start to think that I am truly evil.

There were very few meetings after that that summer, and it was the same for the rest of the school year as well. Time passed quickly, and steadily Harry and I developed a friendship, a kind of understanding between one another that no one else had, and we remained close friends for the years following, we still are now, in fact.

This is the end of this story. Perhaps there will be another in the future, another tale like this to tell. I certainly hope it will not be like this one if there is another, but only time will tell.

I am getting old now, too old to recount this for much longer, so perhaps I should just give in and stop trying to make my time here seem longer. I feel it is time for a classic ending to this, so I big you good bye, and I hope you enjoyed my tale.

A/N: Okay, those of you that have been following my most recent fics will know I've not been satisfied with my writing as of late, but it seems I'm back in business! You have no idea how pleased I am with this! It's amazing! Look out everyone, coz Byproduct of Evil is back in action!

That's enough of that. How'd everyone like the ending? I needed to end this now, otherwise it would have dragged on for who knows how long. Plus it has a happy ending, which is good.

But for those of you that didn't want it to end so soon, I promise I'll be writing a prequel to this once I've finished my most recent fic and I'm a good way into an AU for that fic as well. And possibly will be a good way into my PotC one too. Right now I just have too many stories going for me to write effectively.

HecateDeMort: I've written more, okay? But this is the end of this. I have seen those sort of Severitus' though. I've seen almost every sort of Severitus challenge response.

redlady27: it was slow, as you can tell. Very slow. Agonisingly slow. For Vernon. No quick Avada Kedavra either!

Padawan Jan-AQ: Here's the next and final instalment.

starangel2106: Thank you! Here's the last bit!

Okay, that's it. Look out for the sequel everyone, though that may take a while. Hopefully I'll start it during the summer some time.

But this is it from me on this. Thank you for reading and peace out!
