Ew reports that Patty Duke will be guest starring in the new season of Hawaii Five-0:
Duke will play an Alzheimer’s-afflicted mother of a murder victim. When the Five-0 team go to deliver the notification, they learn her condition has her believing that her adult son is actually still a child. For a while, the team shields her from the news, but ultimately she must confront her devastating loss.
Sounds like a depressing episode. Duke is just one of the many guest stars that will be appearing in season 2 of Hawaii Five-0.
