Title: Blast to the Past II Chapter Nine: A Demon in the Dark Author: Kitty Malfoy

Disclaimer: Same as before. I own nothing! Except the plot, and most things non-HP related.

A/N: Boy! That last cliffhanger was pretty good don't you think? I thought so too. Didn't see that coming, did you?! NO YOU DIDN'T! And if you did, you're my new best friend, lol. Well, I know that most of you are still kinda confused on how Serenity(Riley) got back to the past. That will all be explained in the NEXT chapter! Aren't you excited? I am too! Here we go!

!*!*!*!*!*!*!*!*!*!*!*!*!*!*!*!

Riley couldn't breathe. Her lungs tightened and refused to fill with air. She clutched at her chest, willing air into her lungs, but it was to no avail. She began to get dizzy, as the shadow moved into her throat cutting off the air entirely.

Her legs would no longer support her, and she fell to her knees. Sirius tried to help her, but a strong barrier of shadow erupted around her, holding him at bay. She clawed at her throat, needing oxygen, and her body shifted closer to the edge of the roof.

Sirius yelled at her, but his voice was muffled by shadow. She teetered slightly, and then fell. Her body crashed into a large pile of trash, and disappeared beneath it.

Sirius was halfway down the fire escape, and the twins had almost reached her, when the pile virtually exploded. Garbage and filth rained endlessly down from the sky onto them, and they covered their heads defensively.

The shadow had finally won. It had struck in her moment of weakness and taken over. Her clothes had been shredded and barely covered her private parts, and her fingernails and toenails had grown to three times their length and had sharpened to a point. Sirius watched as her milky cream-colored skin blended to black, as her body spun slowly in a circle.

Rows of razor sharp fangs slid between her lips and glittered in the darkness. Riley's long blonde hair spread out around in her in the air, and Sirius and the twins covered their eyes as it burst into flames. The smokeless tendrils of flame floated above her head; hissing and licking around her face. She stopped spinning and when she blinked her eyes switched from obsidian to a volcanic red.

"Mom?" the girl whispered staring at the Demon that had once been her mother.

"Kira! Get behind me!" Sirius ordered, pushing the trembling girl behind him. "Serenity, is that you?" he asked stepping closer.

"I. Am. Sssssshadow." Serenity/Shadow hissed, bearing her fangs.

Kira shook her head. "No, you're Serenity."

Shadow hissed and leapt at the girl, bringing her claws in a downward slash. She broke skin, but it wasn't the girl's. It was Sirius. He was standing protectively over Kira, his arms outspread. Shadow jumped back and settled into her crouch, licking the blood off her fingers. Sirius raised his wand weakly, and a huge, glowing band of green energy wrapped around Shadow; binding her inside it.

Shadow struggled wildly inside the ring, hissing and thrashing about. Her muscles flexed and the band stretched outward. Energy crackled around it as the holding field was strained and pushed to its limits. Shadow screeched and the band shattered. The energy sizzled like fireworks and disappeared into the ground. Sirius raised he wand again, but Kira screamed.

"No!" She scrambled to her feet, and slid around her father. She ran at Shadow and leapt at her; wrapping her arms around her. Shadow screeched at the girl's touch. Smoke slithered out from where their skin touched, and Shadow screamed in pain.

"Ssssstop!" Shadow hollered, trying to yank the girl free. Kira's grip held fast.

"I won't let you go!" Kira screamed back at her, tears forming again in her eyes. Shadow arched back and clutched at her head, and screamed into the night. Her primal scream wavered slightly, humanity creeping into it. Sirius and Leo stared in awe as a bright, golden light burst from the two women. Kira gasped in surprise as her feet left the ground, and she tightened her grip on Shadow as they spiraled upwards.

A hurricane-like wind materialized from no where, and almost knocked Sirius and Leo over. Starting from the roots, Shadow's fiery hair was turned to pure golden blonde that reached her toes. Then the rain started, small droplets hit her forehead washing away the black as if it was only dirt, revealing ebony skin; her teeth lost their fangs and returned to normal. Lastly, the fire left her eyes, and then they were back to their empty blackness.

Then she gasped suddenly, and her body writhed in pain. She twisted her neck around and retched. The night got suddenly darker as if a shadow had descended upon it. Then the sun peeked over the horizon, creating a soft glow around them, and as the sun's first light reached Riley's eyes they glowed golden; piercing through the early dawn as bright as headlights. She and Kira lowered to the ground slowly, and as the light in her eyes faded Sirius saw they were a pure, azure blue with no hint of darkness or fog.

"Serenity" he breathed. She looked up at him and smiled.
