Preview: Stefan and Laura work together to decode the disks. Recap: Gia planned to confront Nikolas about her suspicions that he and Elizabeth weren't really together. She went to the yacht and found him engaged in a Tai Chi workout. When Helena called out to him, Gia hid before either of them saw her. She listened as Nikolas reiterated his demand to Helena that he be given full control of the Cassadine estate. Helena told him that his infatuation with women made her question his ability to rule the family effectively. She no longer believed that Liz was the right woman for him because of her tendency to run to Lucky. Nikolas coldly stated that he would have Liz if he wanted her and he would make her forget all about Lucky. Helena surprised him by mentioning Gia's loyalty, stating that Nikolas needed a woman who was absolutely loyal to the family. Nikolas commanded his grandmother to stop worrying about his choice in women and to start believing that he was the true heir to the throne
