“Hawaii Five-O” has a storied history for creating most memorable Halloween episodes, and for this Season 6’s sixth episode, “Na Pilikua Nui” (Monsters), on October 30, the horrific tradition continues, only this time, on more human terms, literally. While Danny (Scott Caan) gets caught up in the “what if’s” of a father’s worst fears when he finds out that his Grace (Teilor Grubbs) has told a lie to sneak away to a party, Steve (Alex O’Loughlin), Lou (Chi McBride), and Max (Masi Oka) are deep in unraveling the distorted mind of a serial killer, and his mind isn’t the only thing taking it out on them. Chin (Daniel Dae Kim) and Kono (Grace Park) step in on a strange blood bank break-in per a call from Jerry (Jorge Garcia), and end up shooting for their lives, and the story leaves any fan with a warmth that will melt hearts just like the Hershey’s kisses in the trick-or-treat buckets.
A Halloween chase isn’t all that ominous when one of the participants injures his ankle, and the scary pursuers summon assistance, and discover that a very realistic body nearby the path is no prop, but a true decomposing corpse. The walk to this crime scene, of course, is no fun for Danny, draws the correlation between the length of the walk to the scene to how bad the case will be, but he’s really distraught over his daughter being a teenager now, who doesn’t want to spend Halloween with dad anymore. Further investigation shows spread victims and body parts– this is a serial killer on the prowl. Max allows his expertise and heart to help overtake his wrenching memories of his mother’s death, and reveals that there actually are four female victims, in pieces and parts, partially, but not fully embalmed, and some previously frozen, and then left. On a lighter note, following his tradition to honor the thespian talents of Keanu Reeves, the medical examiner dressed as Le Chevalier Raphael Danceny of Dangerous Liaisons, the masterful tale of seduction and betrayal that somehow had not made it onto either McGarrett’s or Williams’ must-see list. Jerry is keeping with his own Halloween homage by dressing as Dracula, and donating blood at the blood bank, but his nurse, Lia (Brianne Howley) really doesn’t play along like he would hope. It’s all business as usual with blood pressure until some marauders make their way through the door with guns, going after a very unusual commodity.
One of the victims, Kimberly, is identified and traced as a vacationing daughter traveling alone from Japan. Danny’s forensically fixated nephew, Eric (Andy Lawrence) finds a portion of a necklace holding blood that is identified as being a possible suspect’s, Mark Shepperd (Michael Graziadei), who is brought from the brink of death, found hanging from his ceiling. He identifies his own girlfriend, Tamara, from the photos of the victims, explaining that he was so distraught over the loss of her love that he discarded his necklace. In the middle of this dark situation, Danny gets a call every parent dreads, That Grace is not where she is supposed to be, at a friend’s, but snuck away to a Halloween party with older teens. Steve tells Danny to take care of his daughter, and not to terrify her, while he and Lou will take the case. In a priceless scene, Danny’s “cargument” this time is with his invisible daughter, trying to explain his distaste for lies, recalling every rationale, rambling in both nonsense and sense that only a parent understands. Kono at first thinks Jerry is playing about the break-in, but gunshots quickly dispel that notion, and the nurse makes it even more clear that this is a serious case, because the gun-toting gangsters were after a very rare form of blood, peculiar the island natives, and they took it all. When she and Chin do a check at a pet clinic, they notice right away that they have a hostage situation with the receptionist (Sarah Hatfield). They have to proceed with caution to save her life. Lou deduces that this body part butcher may be someone that works at the airport, based on the ID found pertaining to the victims. There is a baggage handler who is also found to be an expert embalmer. They know this cannot be coincidence, and configure the scenario that he is trying to “build” himself a new love, based on the body type of old pictures, akin to Dr. Frankenstein.
Danny arrives at the hot Halloween party, and spies Grace, who is none too happy to see dad. He advises her new acquaintance to “step away from my daughter,” and promptly escorts her out. There is an “unauthorized surgery” being performed at the pet clinic, and leads take Steve and Lou to a cottage where Oakland, the killer, “processes” his victims. Grace listens in silence to her father’s lecture about safety, the worry she caused, and how someday, she will understand it all. His emotion causes him to not see a critter in the road, and he swerves and crashes into a guardrail. Without cell phone reception, he and Grace have to take a scary walk home. Steve and Lou get to the spot for the terrible taxidermy, but the darkness makes processing near impossible, so Steve directs Lou to the fuse box. Even McGarrett finds himself unsettled as he says, “Talk to me, Lou,” prowling the dark corners of the creepy residence, down to deepest levels, where he and “the doc” go to macabre battle, leaving Steve bloodied, and leading to the discovery of the “assembled” bride. Chin and Kono have to out-fire the pit clinic shooters, so it’s a good thing they know how to get their targets. Steve drops by to give Max a special thanks, reminding him that he won’t find his mother in those case files, because “she’s right here,” pounding his heart.
As Danny gets his precious car towed, Grace observes that he lies to the tow-driver, telling him his band’s music was great. Danny defends that his was a lie for a reason, without harm, trying to differentiate from his daughter’s situation, and detailing that he expects an apology to her mother, too, which she does, immediately. “I love you, Danno,” she says, hugging her dad goodbye. The scene switches to the hospital in this heartwarming “Hawaii Five-O” Halloween, with Danny taking his young son, Charlie, room to room to GIVE treats to every child. In a truly tender moment, he makes his “little cowboy” promise that he’s “not going to grow up.” If only…..
