Hawaii Five-O blends crime-fighting, camaraderie, and re-creating a new life in this week’s 16th episode of Season 4, “Hoku Welowelo” (Fire in the Sky). The sky seems to really be falling, and the team really doesn’t know who can be trusted in the case of a triple homicide. Old friend, Jerry (Jorge Garcia) comes on scene to help solve the case using his basement bevy of information, and Steve (Alex O’Loughlin) and Danny (Scott Caan) clash over Danny’s mom, Clara (Melanie Griffith) desiring more freedom and adventure. Captain Grover (Chi McBride) proves himself a trusted friend to Steve, but Steve doesn’t trust a Chinese foreign agent.
A honeymooning couple has their fishing boat struck by a massive, blazing piece of metal, before being gunned down. Steve is suffering through another fitful night, dreams of his wartime battles and the loss of his friend, Freddie Hart, still plague him in dreams. He calls Lou Grover over for coffee, and faces the fact that he has more than his father’s killer to contend with, even in the far-off islands. Danny knows his mom is up to something by the way she bags him a favorite lunch of tuna fish salad sandwiches, and it so happens that Steve and Lou have deemed it appropriate to allow her to go along on a ride along. She leaves under Danny’s protest. Danny is so upset that he declares “You are no longer my friend,” to his partner, especially after learning he was the only one who didn’t know about the plan. Steve retorts that Danny just “woke up on the wrong side of life,” as they go to the crime scene. Jerry also has permission to come on board, and immediately relates the case of the Chinese satellite, the Black Unicorn, prized enough to take lives. Jerry gets on the wrong side of a Vice Admiral, pitching his case, calling the incident only one of “space junk” falling. Steve pushes even harder, accusing the superior of lying when he never looks up from the photo evidence. Clara pleads with Lou for a “more adventurous” look at police life, but he promises he won’t put her in harm’s way. While Jerry is digging for schematics the Black Unicorn in his files, he is cornered at gunpoint by a Chinese spy, Zi Chen (Elaine Tan), before he takes her down with his own taser, calling Steve to the scene of his “totally awesome takedown.” The fallen agent weaves a convoluted story of love and betrayal from her fiancé, Quan, and promises that she is truly out to save her country. Danny is particularly leery of her information, but they take her along for contacts.
Clara has a little too much fun at the gun range, shooting everything in sight, and showing that she already is becoming a weapons aficionado. She revels in getting “hit on” by another officer. Jerry and Catherine (Michelle Borth) rendezvous in the park to receive classified information, and Jerry asks “shouldn’t we pretend to be a couple,” which Catherine declines. When Steve and Danny arrive at the location of Chen’s team, they are all found dead, and Steve uncovers a bomb beneath a body. The bomb squad diffuses that situation, but Danny is still trying to defuse his mom’s interest in his work. Chen insists she must bring down her own fiancé, or be under threat of treason in her country, along with her family. Kamekona (Taylor Wily) serves up sweet talk for Clara, along with his shrimp. Clara takes a call from that flirting officer, Kevin (Bob Arnold) who asks her out on a “coffee date.” The team is investigating leads to the word “Taylor,” whether person or occupation, and finally go to a “spy shop,” where Steve handcuffs Chen to a steering wheel, but she’s too slender and savvy to stay, breaking her way out while a deadly shootout happens inside. She chases down Quan, but not before he shoots her. Steve tells her that he has arranged for her and her team to return home while she lies in her hospital bed, selling it with “I know what it’s like to serve my country.” The goodwill isn’t real. Steve goes to a contact, dropping a flash drive of Catherine’s information into a paper bag, and assuring what Chen’s true fate will be once home.
Jerry is sure he is a “marked man” after his Chinese spy interface, so he asks to move in with Steve, to a far less than enthusiastic welcome. Danny is up waiting for mom when she returns from her date, promising that he was a “perfect gentleman,” but that the date was not what she expected it to feel like. Mother and son make it a movie night on the couch.
Hawaii Five-O adds fuel to the relationship fire next week, when Tom Berenger re-enters the cast as Danny’s dad.
