Michael Corinthos (Chad Duell) from General Hospital believes he has finally gained the upper hand with Nina Reeves (Cynthia Watros). Ever since Nina married Sonny Corinthos (Maurice Bernard), Michael has been aware that Nina was the anonymous tipster who reported Carly Spencer's (Laura Wright) crime of insider trading to the SEC. The consequences for Carly were severe - she lost her shares in Metro Court and was fined a staggering $5 million. Drew Cain (Cameron Matheson) is currently serving time in prison to protect Carly from the legal repercussions. Although Sonny and Carly are divorced, they maintain a close relationship.
Originally, Michael intended to inform Sonny about the truth, but he hesitated after witnessing Sonny's happiness with Nina. Instead, Michael decided to confront Nina directly. Michael is married to Nina's daughter, Willow Tait (Katelyn MacMullen), and he recently discovered their familial connection. Despite their complicated past, Willow reluctantly agreed to let Nina back into her life.
However, now that Michael holds this secret over Nina, he plans to control her access to both Willow and their children.
Considering her past involvement with the manipulative Dawn of Day cult, led by Shiloh (Coby Ryan McLaughlin), she will likely see similarities between Michael's actions and Shiloh's control.
