In "A Tale of Two Sisters," a woman breaks a childhood pact with her irrational sister...and everyone suffers the consequences.
Clara thinks back to when the two of them were children and the night their mother died. She and Adelle had made a promise that they would always be together, and Clara had kept that promise. Adelle was abnormally clingy, but Clara didn't mind, she assumed that Adelle would grow out of it.
Then, Clara met Doug and fell in love. Adelle was furious! From then on, she refused to have anything to do with her sister. Clara tried to mend their relationship, but Adelle would not forgive her.
Clara would later find out that her sister was not only hateful but...dangerous.
