A/N: This chapter is going to be rather violent so I'm giving you a heads up on it.
Voldemort's Pet
As soon as she apparated back to the gates, she lowered her dark hood. It was all going according to plan. She would soon be the Dark Lord's favorite. She had wanted it so long, and now it was so close to being hers. However, she had one last mission to complete. The corners of her lips slowly curled upwards. She drew in a deep breath and walked in the castle. She'd prove herself worthy tonight.
She walked towards the moving staircases. She knew that's where her target would be right then. She had seen it. Sure enough, she was correct. She quickly pulled up her long black hood so that her target wouldn't see her. Moving fast as lightning, she sprinted towards her target. Her long arm reached out and snatched the back of her unsuspecting victim's hood. She yanked back on it before releasing the hood. She grinned from ear to ear as Aurora Sinistra tumbled backwards down the stairs before coming to rest near the entrance of the Grand Staircases.
"Awe, you poor thing," she said with a smirk on her face while she glanced down at Aurora. "Are you all right?" She softly laughed when she heard the painful moan. "You know, Sinistra, you should really watch where you're going. Wouldn't want you to get hurt, would we?" Another pained moan escaped Sinistra's lips. "I've got a message for you and your sweet husband, dear." She then pushed up Sinistra's left sleeve before pulling out a knife. Lazily, she carved the Dark Mark into Sinistra's arm. When she was satisfied with her 'artwork', she dropped the bloody arm. "Such a waste you were, Sinistra. You married beneath you. Do you know that? He's a half-blood. He'll always be one." Her eyes then darkened. "You called yourself a Slytherin. Ha! You don't know the meaning of it," the woman said with a sneer. She then stood up and held the bloody knife in her hands. "I wish I could stay to see his face when he finds you, but I know it already. I regret I must be on my way, lots of others to punish before my master returns. Sweet dreams, Love," she said with a smirk. Whirling around, she fled the scene of her crime. By the time anyone found Sinistra, she'd be dead. As soon as she passed through the gates again, the woman went to her master's side again. "It's done, my Lord."
"Excellent," Voldemort hissed in his airy form. "Then I see I won't need you anymore. Avada Kedavra," he lazily said. The woman's lifeless body slammed against the ground. "Farewell…"
A/N: So...who do you think his pet was?
