Grievous growled, the sound was alien enough in his metal shell. Wasn't it enough he was in this tournament? He wasn't in the mood for having to show up to his "Winter Ball" as he wasn't built for dancing, he was built for combat and hunting. His golden eyes narrowed on the Transfiguration Professor, his disgust evident in his choice words to her.

"I'm not going."

That made the older witch sputter before the Vampiress took his arm and smiled sweetly to the woman.

"One moment, miss"

As she pulled him to the side, she seemed thoughtful and smirked devilishly.

"Do you know how to dance to the music they have?" She asked him softly, her words barely above a whisper.

"Indeed, but I have no need for it…" He started before she stopped him.

"Good, just don't mess this up, I have an idea." She then pulled him back to the Professor and smiled.

"We'll go, but only for one dance." She answered the elder woman, smiling until she left.

Grievous looked at the Vampire, wanting to know what she was planning in that ageless head of hers. It was clearly something not to his liking, but she had something.

"What is it that you are planning?" He hissed, a dark edge in his voice.

"You'll see, Grievous." She calmly answered back.

It wasn't long before the ball came about, seeing that the metal bounty hunter and his "date" were there at the doors that led into the great hall. Grievous felt somewhat constrained by his new dress suit, all stiff and unyielding. The only thing that was good was that his legs were still not human like enough to wear the bloody pants that came with this thing. His cape had been switched out that a black cape that had classic cliched high collar.

His date wasn't in something so plain, as she had been waiting to wear this dress, or so he had been told. The dress was blood red, had no back, no straps and clung to her every curve with frightening closeness. A slit in the side showed off her right leg, her feet clad in black dancing heels and her hands in elbow length fingerless gloves. She smirked as she looked like the Countess she was.

"Countess Marrilane Von Draken," She had told him as she had put on her outfit, letting him watch her, "That is my full name, you may call me Mary."

He waited patiently as the others came up, Fleur Delacour and her date, who was clearly under the effects of close allure exposure. Cedric Diggory and his date, an asian looking teenager in a conversitive blue dress and finally Viktor Krum and his date. She looked like a good looking girl in a pink dress that fit her nicely. Grievous noticed that all three female dates were giving Mary jealous looks, the vampiress only smirked and slightly flaunted her much more mature body but stopped as Professor McGonagall strode up to them.

"This way champions." She lead them into the Great Hall, Grievous noted sourly that everyone was either staring at his date or Fleur like pieces of meat.

He didn't even let himself get into the meal before the dance, Mary simply sipped at a goblet filled with blood like the finest wine. Most if not all stayed away from them except Fleur, who talked quietly to Mary until it was time for the first dance. Leading his date to the dance floor, Grievous was pulling the memory of the dance moves that were accepted in this waltz before Mary placed a white mask on the side of his face.

"What is this?" He asked before she purred and the lights went dark.

He could easily see her due to his alien physiology but then the music turned into the song of something that wasn't from this part of the world. He then realized what the mask was for, Mary had set everyone up. He could only grin as she spin around and a light appeared out of nowhere, making her the center of attention as smoke billowed in, covering the floor in a dark manner.

"In sleep he sang to me, in dreams he came, that voice which calls to me, and speaks my name." She sang, her voice filling the room as she danced sensually, "And do I dream again? For now I find the phantom of the opera is there inside my mind."

The music filled the hall as he felt himself move, letting himself go and catch her, his voice gaining a soft but deep tone as he sang the next verse of this song, "Sing once again with me our strange duet; my power over you grows stronger yet. And though you turn from me to glance behind, the phantom of the opera is there inside your mind."

"Those who have seen your face draw back in fear." Her hand touched the masked part of his face, singing before she spun around and stopped, her hand in his, "I am the mask you wear,"

"it's me they hear." He stated, his grace only matched my his partners, pulling her close and dipping her down.

"Your spirit and my voice in one combined;" They sang together, dancing around the hall as the other champions started dancing with them, "the phantom of the opera is there inside my/your mind."

"He's there the phantom of the opera." The champions and their dates sang, sounding ghostly in the quiet hall, "Beware the phantom of the opera."

"In all your fantasies, you always knew that man and mystery," Grievous sang, twirling Mary around his body, his cape fluttering as she spun around him.

"were both in you." Mary finished for him and came to a stop, her back to his chest.

"And in this labyrinth where night is blind, the Phantom of the opera is here" They sang as the champions sang in the background, "inside my/your mind."

"Sing, my angel of music!" Grievous intoned, his arm going across Mary's shoulders, his face on hers before he whispered, his want seeming to appear as the song neared its end, "Sing! Sing for me! Sing, my Angel of Music! Sing for me!"

Mary did sing, her voice entrancing the entire hall before the song abruptly ended and both she and Grievous were nowhere to be seen as the lights returned to normal.

It wasn't until a week later that Grievous or Mary appeared again, much to some of the adults frustration. When asked, Grievous simply stated that was his business and not theirs. Mary nodded and didn't reply to the questioning either, having nothing to say to the magical humans. Grievous knew what he and Mary had been doing however, bounty hunting. Nothing wrong like a little "date" during a job, Mary had enjoyed it as she got to drink the blood of the victims.

"I think I would like to go on another date like that, Grievous. It was most enjoyable." She purred, licking her lips as she leaned against the wall.

Grievous smirked, his eyes showing how much he enjoyed that week.

"Yes," He humed, "I think another is needed in the near future, Mary."
