The back door or the house slid open and out came a bumbling Stiles still complaining about Peter. And the sight of his two naked children in the backyard only made him hate the Hale family so much more.“Oh my God, Theo. She's your sister!” Stiles whined storming back into the house and bumping into Derek. “Look, dude. I never thought I'd say this but you are the most normal person in your family.”

Letter to my dearest

by Aerith_Mon_Kishu

Before his child is born, Thomas Sharpe writes a letter for his heir in which he tries to explain what makes his family so sinful and why they had to do what they did. extract: No one ever knew. And whoever knew, we took care of them. This too my sister showed me. We shared the most gruesome actions that became mere memories by now. Soon the one our family chose as your mother will die the same death as the one before her, opening old scars for me. But I never truly loved her anyway. She was just a tool. And my sister will make me forget. That is the very epitome of evilness I will lay down next to you in your cradle. But it is in your blood. You are a Sharpe, and I hope that when you find out about our secret you will not fear it. Be proud of what you are. Be glad for every moment you exist. For the devil will come for you soon enough once you do your last breath. And only because we did something no one should ever do...
