Demons come out and play (regan X brother)

Thomas was 12 like regan, he was her sister, he heard strange noises from her room and saw straps around her wrists,
"What the hell..?" Thomas said
Regan's head turned to her brother
"Evening, brother..." Regan said in her normal voice. "Why is everyone freaking out?" Thomas asked, regan smirked "because they're afraid of me."

Her face turned pale with bleeding cuts around her face and hands (etc) her eyes turned yellow. Thomas took a step back but, the door closed right behind him.
"You shouldn't leave." Regan said in demonic tone.
