"You're not the doctor." She whispered as the… thing that was possessing the Doctor circled her. A slight smirk coming across his face as it continued to dance around her. "Who are you?! Leave him alone!" He laughed, as if it was genuinely funny that she was telling him what to do. "What… What are you?" Totally playing up the insecure, no knowledge idea. Keeping quiet the fact that she knew exactly what it was, she tried to keep the disdain out of her voice as she spoke; too easy to cover it up with fear. "Please, we're just travelers." She whispered quietly, tears welling in her eyes as she spoke.
"Oh," He says, stealing the Doctor's voice, stealing his smile. She shivered as the air grew cooler, not just from the iciness of his voice. The total flip-side of who he really was. "Just getting the feel for this new body, it doesn't matter about who I am." He got right up close to her face, pushing some of the girls coloured hair from her face, his breath hot on her face. She tried not to flinch away at the shock of how close he was to her. "I can hear his thoughts in here, there's so much going on in his head. He's screaming for you to run." There's this sick little smile on his face, "Why aren't you running yet?"
"Because, I know something you don't." She smiled back at the face of death, his face fell from smiling. "Ever heard of Dean Winchester." And she threw something at his face. Holy Water, she always kept a flask full in her inside jacket pocket, especially after the nasty business with the poltergeist. The Doctors skin sizzled as the smell of sulphur in the air was unreal as steam floated upwards, his eyes turned black again and he breathed heavily, it bared its teeth at her and tried to reach for her, only she splashed it again causing it to scream with pain this time. "Yeah, you learn a thing or two from him." She shouted as she finally started running.
