"Why did you take so long to tell me this?
"I didn't consider it necessary at the moment"
"You didn't consider being possessed important? We might use hell magic, but that does not make us friends with demons!" Richard yelled at his sister. "Clearly you do not know how dangerous demons are, if you knew you wouldn't have one trapped inside your body"
Rachel just stood still glaring at her brother without knowledge of the words to say back. Richard probably had no idea how it felt like being weak and neglected, this was the only way she could make up for her being weak. It didn't matter what words he said, she wasn't going to let her only source of power go.
"Come on I'll help you get rid of it" Richard offered. It was all thanks to Charlotte that he was able to discover that her sister was harbouring a demon. He hadn't known this before, but it seemed the descendants of Cain had the ability to detect all sorts of emotions, especially negative ones.
