'Hawaii Five-0' Season 9 Air Date, Spoilers: Is Steve McGarrett's Nemesis Really Back from the Dead?

Mark Dacascos's run as the criminal and former agent of the Chinese Ministry, Wo Fat, may have ended when Steve McGarrett (Alex O'Loughlin) shot him in the head in their epic season 5 showdown. But it seems the people behind “Hawaii Five-0” season 9 are sticking to their plan to remake the show's very first pilot episode by having Wo Fat come back for the upcoming installment's season premiere.

Fans who have already seen the actor's upcoming return in “Hawaii Five-0” season 9 sneak peek photos may be left speculating about how Wo Fat can come back from a bullet to the head. Fortunately, a season premiere preview video recently released by CBS may give clues on how Steve McGarrett's first nemesis will rise from the dead.

With McGarrett expected to go through the sensory deprivation tank and the Wo Fat that fans know already killed back in season 5, there is a possibility that the Wo Fat in “Hawaii Five-0” season 9 is simply McGarrett's hallucination. Why Wo Fat will be a hallucination can be explained by “Hawaii Five-0” season 9's most recent casting.

Diligent viewers anticipating the return of “Hawaii Five-0” season 9 remember that “Mistresses” actress Rochelle Aytes has already been cast as Steve McGarrett's former flame, CIA Agent Greer. “Hawaii Five-0” season 9 showrunner Peter M. Lenkov has already confirmed that Greer will be the upcoming installment's big bad.

Greer could be behind the manipulation of Steve McGarrett's consciousness, making him think that his biggest enemy has returned from the grave. Fans already know that this won't be the first time that McGarrett has had very vivid hallucinations.

Fans hyped for the truth about how Wo Fat escaped his fate in season 5 can look forward to “Hawaii Five-0” season 9 and its season premiere episode when it airs tomorrow, Sept. 28.
