When the twins, Skye en Ciara were just five years old they went to live with their grandparents, Dianna and Clyde. Their own daugther Iris, left by the girls dad shortly after their birth, had become all consumed by the theories of what really goes on in Strangerville and what truths the military are hiding. Dianna and Clyde didn't feel it was safe for the girls and brought them to Willow Creek.
Skye has empathy for her mother and believes that if she is so all consumed by it, maybe there is some truth to it. Ciara wants absolutely nothing to do with her mom, if she loved them she would have seeked help, right?
