A cold smirk upon her face, Willow arched an eyebrow as she gazed at the gathered group of frightened humans. "Sounds like fun," she replied to Spike. Raising one arm in front of her, palm facing outward, she sent a bolt of energy flying directly at the pay phone in the corner. It exploded, sparks flying everywhere, and instantly a man shot to his feet still holding onto no longer attached receiver.
"I was just... just..." he began. She shut him up with a look.
"You were trying to call for help. Don't lie, it's rude," she snapped. "Now come here."
He rose to his feet, his knees visibly shaking... then spun on his heel and darted for the back door. With a heavy sigh, Willow teleported in front of him, causing him to crash into her chest rather than his chosen escape route. Wrapping a hand around his throat, she lifted him off the ground and stated in a flat voice, "Big mistake."
Slowly, smoke began to rise from beneath her palm, against the tender skin around his neck. Kicking, muffled screams bursting past his lips, the man clawed at her hand and tried to get away. Willow, however, increased her grip and watched with detachment as the smoke began to grow thicker. Large plumes of grey and black floated upward toward the ceiling until, quite suddenly, his entire head combusted. Dropping the remains of his corpse, she turned her attention to the rest of the patrons.
"You can deal with me," she said simply. "Or you can deal with him. Anymore escape attempts, though, and I'm going to peel every single inch of skin off your pathetic bodies until nothing but bone remains. Got it?"
And, tossing a smile Spike's way, she said, "Have at it. You've got a couple of years worth of repression to make up for, way I figure." Then she began to smile as, almost as a whole, the patrons of the bar began to scream when they realized there truly was no escaping their fate.
