Someone caught me doing a demonic spell on them...right as I was amidst the cast...should I confront them?

They saw me performing and immediately wanted to leave my home but I wouldnt let them...I told them that "I knew they would see me and that I was playing with their head" so.....I wonder what will happen next.........will my spell and demons perform better since Ive gotten inside this persons head??? Psychosematic ????
