‘Hawaii Five-0’ Season 9 Episode 10 Air Date, Spoilers: McGarrett to Face Risky Mission in Montana in ‘Pio Ke Kukui, Pō'ele Ka Hale’

“Hawaii Five-0” season 9 episode 10 is titled “Pio Ke Kukui, Pō'ele Ka Hale” and it means “When the Light Goes Out, the House Is Dark.” It will be about Steve McGarrett and his task to fight people who are trying to get revenge for a previous mission assigned to SEAL.

As per CBS press release, the synopsis for “Hawaii Five-0” season 9 episode 10 reads: “After fighting off an assassin in his own home, McGarrett and Joe White flee to Montana to prepare for a battle against those exacting revenge for a past SEAL mission.”

CarterMatt suggests that since Agent Greer (Rochelle Aytes) is returning in this episode, McGarrett’s life could possibly be in danger because although Greer and McGarrett had a past, she could cause chaos because she knew a lot about him. Greer could use the info to bring him down if she wants to that is why her return is not really good news.

In any case, “Hawaii Five-0” season 9 episode 10 will also feature another guest that fans will surely like. Terry O’Quinn is coming back as Joe White and he will work again with McGarrett. As posted in the synopsis, the two will work together to solve the issue in Montana.
