Teresa raised her head and growled.
Cervilleaux took a step back, stumbling against his desk as he sought to get behind it and its dubious protection. He made an effort to smile blithely but failed.
“Now, I know this is hard for you to take, my dear, but please consider my position…delicate political balances to be maintained…”
Her voice was already halfway into a canine snarl. “You killed him…”
The demon tried to back away further, but once again fear tangled his limbs and he almost fell, grabbing onto the desk for balance. He knew that the chances of a low-ranking demon such as himself surviving an attack by an enraged werewolf, even a half-grown one, were very slim. He held out one arm in front of him as if to ward her off. “My dear…”
Teresa lowered herself closer to the ground, bunching her body, tiny pinpricks of pain already attacking her flesh. Her bones began to melt, to change, but she didn’t even pause to consider the agony of it this time. Her hips dislocated and relocated with a crack even as her jaw ruptured and fused itself again, tiny hairline fractures healing along with complete splits in the bone, room in her mind left for only one simple, terrible fact: Liu was dead, and his murderer was going to pay.
In her last moments of humanity, she paused.
“You should have killed me too.”
And then she leaped.
Teresa hit the demon in Half form, more than 200 pounds of solid muscle knocking him from his refuge and onto the floor. Her claws buried themselves in his arms, pinning them to the ground. The minor demon’s gibbering scream rang out through the room, panicked and desperate, but Teresa’s wolfish instincts had taken complete control. She opened her gaping, fang-studded maw, saliva pooling with blood, and began to close it around the demon’s neck.
“Teresa! NO!”
Bands of iron snapped shut around Teresa’s body and she was jerked backward off Cervilleaux, her claws tearing through flesh and muscle as she was dragged away, scrambling for purchase on the slick marble floor. She twisted and snarled, writhing to escape her magical bonds, but she was thrown to the ground. A figure rose up over her.
“What are you doing!?”
Fury coursed through her animalistic mind. A human was holding her back, a puny human. She flexed wildly and arched her back, struggling to break free from the holding spell. She would kill the magician who dared keep her from her vengeance, and then she would descend on the pathetic wounded demon that had done this and finish the job.
There was a slamming noise, and then two other figures burst through the door, yelling words the werewolf couldn’t understand.
“Teresa!”
“What happened?”
“Don’t worry, I’ll take care of this.”
The young magician, dripping with sweat from the effort of holding the thrashing Halfwolf still, dropped to his knees beside her. She swivelled her head and snapped at his face, but he grabbed her firmly below the jaw and held on. His mouth moved, his features contorted themselves into a look of intense concentration, and he spoke a word of terrible power.
Lightning arced through the creature’s body, a deafening crack and sudden, incredible pain, and then Teresa was lying on her back on the cold stone floor, and looking up into the face of Liu: sweating, furious, and very much alive.

dude! that is so awsome! i mean, all of your writing's awsome so kal va'chomer this'd be, but still. AWSOME! it's so cool. i wanna read more. now! but, i have one or two questions:

how come what's his name - Cervilleaux - didn't move while teresa was changing?

why does it seem like liu's furious at teresa. i mean, by how teresa was acting, they'r obviously close. and she was taking revenge 4 him. why does he seem mad? and if he's still alive how come cervilleaux didn't mention that 2 - i dunno - save his life !?

otherwise, awsome! 'specially your descriptions. i like how u described her changing. i can't figure out how to describe changing. write more! :D
