HAWAII FIVE-0

PREVIOUSLY ON... | As Kono ran off to China with Adam and Danny reunited with Gabby, McGarrett visited Wo Fat in prison -- having learned that his mother had once, mysteriously, done the same! But just as he arrived, unseen forces came after the enemies, working their way through the cell's steel door... COMING UP NEXT | Who's knocking on Wo Fat's door? "If they made it that far, they're pretty formidable. And if Wo Fat is scared, that's a big deal," says showrunner Peter M. Lenkov. In short, "The people on the other side are a payoff to a larger story." With regards to Kono's absence (she'll appear in "a bunch of" early episodes but won't rejoin the team until about midseason), Five-0 "will feel fractured, like a three-wheeled car" with a key player MIA. Enter Chi McBride (Human Target) as Lou Grover, a SWAT Captain with whom Steve will at one point reluctantly be partnered. "If people thought McGarrett was ballsy and lived by his own rules, they haven't met this guy yet," Lenkov attests. "He's going to give McGarrett a run for his money." Also ahead: More on the Doris/Wo fat connection ("It's not the obvious answer"), a Chin Ho flashback episode, McGarrett comes to regret encouraging Catherine to work for Billy's security firm, and an hour that revisits Pearl Harbor through the eyes of Steve's late grandfather. TVLINE BONUS SPOILER | Lost fans can count on a fun in-joke -- "a little deserted island reference" -- when guest star Jorge Garcia shares scenes with Daniel Dae Kim in Episode 3. Plus: We may get a song from Carol Burnett, when the TV icon pops up as Steve's aunt. http://tvline.com/2013/09/03/fall-tv-spoilers-2013-shows-ncis/#!21/hawaiifive-0/
