It made no difference. The Demart loomed closed towards her, as every happy memory vanished and was replaced with sorrow. She saw her mother die in the kitchen as icy horror gripped her heart, flaking away the joy. The Demart waited to take away her soul, for none had seemed so innocent, so beautiful. It changed into herself to show her killing her family as she shook her head vigorously at the murder. She saw her hooded eyes kill.

Pain came when she realized the hollow scream was because she was fighting herself.
