Count DAYS's Lauren Koslow (Kate) among those who were surprised by Ian Buchanan's (Duke; ex-Ian, DAYS) unexpected appearance on Tuesday's GENERAL HOSPITAL. "Ian keeps a really good secret because I didn't know!" smiles the actress. "I'm so thrilled for him. I was not happy for me because I loved working with him. He's a tremendously talented guy and a wonderful person. His final scenes on DAYS with James Scott [EJ], Joseph Mascolo [Stefano] and me were superb. He is beloved by the daytime audience and rightly so."
