Something wicked this way comes [witch twins mates] {avengers/twilight}

Soulmates?

One of the three kings approached the other whom stood in between the other two before holding his hand in a steady grip. Almost immediately afterwards the brother with long black hair whom the other brother had gone to let out a maniacal laugh. Wanda looked over to her brother in confusion only to find him trying to contain his laughter at the strange sound that had left one of the kings' lips. The brunette sharply elbowed her brother causing him to groan in pain but all traces of humour were now gone from his face which had bee the brown eyed girl's intention. Satisfied with her work, she turned back to face the group that stood on the other end of the clearing, facing them with glaring red eyes causing the brunette's hands to begin twitching once again.

"Anime gemelle. Soul mates." A high pitched yet soft voice brought the twins attention to the source which appeared to be one of the kings.

"But master, they can't be." The small, ruby eyed blonde spoke almost pleadingly.

"Ah, but they are, as dear Marcus here has shown me. However, I must ask Carlisle, why would you bring two humans to a gathering of vampires? Did you not think it unwise to tell more mortals of our secret?" The long dark haired king spoke, at first to the blonde girl and then to the golden eyed doctor. Before Carlisle could respond however one of the Volturi launched himself towards the human twins with inhumane speed; he was moments away from grabbing the brunette before the silver haired boy grabbed his sister and sped off to the edge of the woods with a speed that caused time to almost stop entirely for Pietro.

The vampire was left with a stunned expression before he caught their scent again and charged. A growl left the brunette as she pushed her hands forward and with it, pushed a red energy towards the blood drinkers which froze him in place.

"If someone doesn't get him under control, I will kill him." Wanda spoke, her Romanian accent thick in her voice, appearing after years of covering it with an American one. Surprise filled both the Volturi and the Cullen's, perhaps for different reasons or perhaps not.

Slowly, a member of the Volturi walked out to grab onto the attacker of the human twins causing the brunette to cautiously release him.

The scarlet witches brown eyes sharply turned to the Volturi in a vicious glare. "Next time I'd recommend you keep control over your members as I won't be as forgiving if it happens again." Her thick Romanian accent deepened in her voice as she spoke monotonously, only unnerving the Volturi members even further. Steadily and gradually, her silver haired brother put his hand on the brunette's shoulder. She looked over, her chocolate brown eyes' gaze now firmly on her brother.

Her pale hand gently grasped her brother's, pulling it off her shoulder and keeping it by her side. Pietro looked down at their joined hands, squeezing her hand gently for reassurance before looking back up at his sister with a smile.

The human twins walked back to their place with the Cullen's and their friends. They continued to look at each other for comfort before slowly returning their gaze to the Volturi with a new fire burning behind their eyes. The Volturi now knew that harming one would only bring a new strength to the other. Together, they were a strength the vampiric world had not known or seen in anyone but the twins of the Volturi. And now, with their mates belonging to the Volturi, the Volturi would be unstoppable and they knew it.
