"Don't let the dark into me,
We kill the angels that hold us so good.
... Don't let the light shine on me,
I am the demon that waits inside you
... Don't let the light shine on me,
I am the darkness that crawls into you" - Gary Numan, Dark

"Noooooooooo!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" Xander screamed. "Willoooooooow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" He rushed against the forcefield again, and this time it gave. He ran past his dark self to reach her. He went to pull the dagger out to find it had vanished, only a wound in the same place as his. He turned her over gently, and like before, smoothed her hair back from her face.
"Oh God, Will." he whispered, his heart tearing in two.
Her eyes fluttered open, and she weakly said, "Xander?" She then stiffened as a spasm of pain overtook her. "Oh God, it hurts!" she cried, no, screamed at the pain.
"Heh, aww, look at the lovebirds. Now you're both screwed. The curse may have not been successful with you, but it'll work for her."
"No!" Xander shouted at him defiantly, and turned back to Willow, "Willow, sweetie, come on fight it. I know you can. You've always been the strong one."
Willow could feel herself being ripped in two. In flashes she saw her own dark self, not unlike the vampire version of her. However, she could see another figure, urging her on, glowing brightly. She squinted trying to see who it was. It was Xander, dressed in white armor. She looked down, and she was dressed in white robes. What the? She blinked, and was back in the hellish desert landscape with Xander, and that... perverted fiend. She was still dressed in white though. She could feel the same power she had felt earlier surging through her, though it was coming from within herself, and from Xander? What was happening? She stood up, no longer in such agony.
"Willow? What's going on?" Xander asked her, noticing the change in her apparel. He looked down at himself, and he was dressed in white armor again. "Ok, this goes way beyond wiggins here."
"Xander, what's happening?" Willow asked, "The pain's gone."
Xander's dark self blinked in confusion, "Both of you? What the hellmouth is going around here? This wasn't supposed to happen!"
"Can I play? I'm bored." A slinky female voice then asked. The three stared at the fourth figure. It seemed to be Willow, but again, it was a horrid perverted version of her. Very much like her vampire self, only this one appeared human, but evil.
"Well, well, the odds just improved. Thanks for the gift, man," the dark Xander smirked as he ogled the dark Willow. She sidled up to him like a cat, smiling sensually. The two wrapped arms around each other, and kissed passionately. Very passionately, almost to the X-rated point by the looks of it. Willow tried to control her nauseous stomach, while Xander couldn't help staring in fascination. The dark Willow then stepped away from the shadow Xander, and strolled over to Xander, who was partly repulsed, and partly lustful at the sight before him. The idea of Willow looking, well, hot, was still a foreign concept to him. She wrapped her arms around him, and kissed him, no more, like inhaled his mouth, biting hard on his lip. Willow pushed the pair away, only to be grabbed by the other Xander. Her anger only fueled the inner power seething inside her.
"Enough! This ends now!" she shouted, though it came out as a command. Her own voice seemed unfamiliar to her, but it didn't matter. She was suddenly surrounded by a bright aura of light. It exploded outward, and sent the dark Xander flying. Xander managed to push away the other Willow, and ran toward Willow. He stared at her. She had somehow grown wings, full angelic wings that sprang from her back, and were now unfurled.
"Willow, how? What?" He stared at her in shock. She smiled and grabbed his hands. He felt an overwhelming energy that seemed to doubly emanate from her, and him. His armor grew brighter, and he could feel wings of his own stretching out to their full wingspan.
"No, no, no, shit!" the dark Xander stomped his feet in frustration, "How?"
The other Willow narrowed her eyes at the bright pair, "You fool! Don't you see! The dagger didn't work. They were already separated!"
Willow said to Xander, "Let's finish this, and go home." He nodded, and drew his sword. A wand appeared in Willow's hand, topped with a crystal spearhead. They walked together, facing off against the dark pair.
The dark Xander drew himself up, and suddenly shifted. His features became less human, and more hyena-like. The other Willow underwent her own transformation into a vampire sorceress. Their faces then shifted to other forms. Xander's was a mix of the Master, Angelus, and his father. Willow's on the other hand, held a mix of her mother, Cordelia, Faith, and oddly enough, Ms. Calendar. The dark pair then charged, and Xander and Willow stood fast side-by-side, against their counterparts. The four broke and encountered each other in two separate battles. Xander and Willow were able to hold their own against their dark selves, but barely. Then the dark pair seemed to catch a second wind, and forced the pair to a standstill. Xander and Willow drew close together as they were backed into a corner, uncertain what to do now.
