The 100th episode of ONCE UPON A TIME also happens to be its return from winter hiatus. After losing Hook to the dark side and death in the winter finale, Emma vowed to get him back from the underworld.
When the show returns, Emma and her friends will be doing just that, but they’ll soon figure out that things are more complicated than anticipated. In “Souls of the Departed, “Emma, Regina, Mary Margaret, David, Robin, Henry and Gold arrive in the Underworld, on a mission to rescue Hook, only to discover that their search will be more difficult than they had anticipated. The inhabitants of the Underworld-all souls with unfinished business and many with quite personal vendettas-hound our heroes at every turn. Meanwhile, in an Enchanted Forest flashback, a familiar face from the Evil Queen’s past returns to present Regina with the perfect birthday gift.”
As you can see from the photos below, two familiar faces that return are Cora and Peter Pan. We’re also going to see Greg Germann as Hades, Tony Perez as Valet and Giancarlo Esposito as Sidney Glass/Magic Mirror.
