I stood on the astronamy tower, bathed in green light from the Dark Mark glittering overhead. Dumbledore's words were still running through my head.

"It is my mercy, and not yours, that matters now."

He could help me...protect me...The Dark Lord wouldn't have to kill me. I wouldn't have to be a Death Eater, I could be safe and free! But only if I didn't kill the helpless wizard before me...

I could vaguely hear voices, other Death Eaters. They didn't matter matter. I wouldn't kill Dumbledore, not if he could save me from The Dark Lord's wrath.

What was wrong with me, thinking that I could kill the greatest wizard on Earth? Oh, yes, i loathed him, Father always said he was the worst thing that ever happene to the school, but he could save me, save my family...

And I just couldn't bring myself to kill him, not when he couldn't defend himself.

Oh, yeah, indirect attempts were simple, i wouldn't be there to see him die. But now...It was much more difficult. I could see his face, he was helpless, and he didn't want me to..it was no fair match! I just COULN'T do it!

Then, I was jerked out of my thoughts as Snape sheved me aside. He faced Dumbledore, his wand raised. and then, I couldn't believe it, Dumbledore pleaded Snape!

"Severus..."

I was speachless. I saw Snape look at Dumbledore with such pure loathing that I will never forget it. I almost told Snape to stop, but was struck dumb yet again as Dumbledore pleaded for a second time.

"Severus...please..."

And then Snape said them. Said the two words that I could not.

"Avada Kadavra!"

And it was done. Dumbledore flew upwards, and then fell. I couldn't think, I just followed Snape, knowing Potter Potter was there. Chasing us, wanting to kill us. It had happened, when I could have prevented it. It had, when it should not have...

-And I wake up, sweating. I relive it every night. I will never forget it. his pleading, the look in his eyes, and how it was gone in a second. I was now in danger all the time, and that memory will never fade. Never.
