Riker made her last appearance on September 21, 2016.
She returned on December 22, 2016.
Naomi Dreyfus is the ex-wife of Raymond Berlin, who organized a ponzi scheme on Wall Street a few years ago and is responsible for swindling people out of millions. She is also the mother of Hayden Barnes-Cassadine (birth name Rachel Berlin), through an affair with Dr. Jeff Webber.
Naomi also continues to insist that she had nothing to do with what her husband did. Raymond is currently serving over 200 years in prison for multiple counts of security fraud.
On June 3, Naomi arrived at Wyndemere, much to Hayden's surprise. On June 4, it is revealed that Hayden and Naomi are estranged because Hayden is mad at her for turning her father into the Feds. Naomi stands by her decision, and offers to help Hayden get the Feds off her back. She also wants her white diamond necklace back. The white diamonds are in Hayden's possession and one was sold by Hayden's husband Nikolas Cassadine.
Hayden says she doesn't have it because Nikolas has them, and they are gone with him. Naomi says Hayden is lying, and says she is just as greedy as her father. Hayden snaps that between her and Elizabeth Webber, she has had enough. Hayden picks on Naomi's reaction, and asks if she knows Elizabeth. Naomi says she sounds familiar, and Hayden decided to just leave the issue alone for now. Naomi suggests she and Hayden search for the white diamonds tomorrow. It was eventually revealed that Naomi had an affair with Jeff Webber and they conceived Hayden, making Elizabeth Webber, Hayden's half-sister.
