Cat spent the ten years after helping break people out of Moab encouraging Helena to take a lead role as a sympathetic face for the Evolved and penned works she dubbed the Evolved Ethics Essays and published under the name Danielle Hamilton, becoming a rock star, finding recognition as a heroine with Phoenix, witnessing the assassinations of the Columbia 14, mourning Helena and the others, becoming a stateswoman, working to get the Chesterfield scholarship established and putting support behind opening the Allen Rickham College for the Evolved started at Yale, inheriting the estate of her parents when they died, and is considering a run for US Senator from New York when April 2019 arrives.
