NCIS Season 24 Episode 5 starts with a girl buying popcorn and ends with two adults learning how to say what matters. In “Speechless,” Jessica Knight earns the trust of a witness who understood a threat nobody expected her to follow. Tim McGee, meanwhile, has plenty to say about his son’s future and can’t find a sentence that sounds like him. Both stories are at their best when someone puts the official business aside long enough to listen.
Katrina Law shares the episode’s best scenes with her real-life daughter, Kinley Andreen, who guest stars as Chloe Sims. Sean Murray plays McGee’s worry as a problem he keeps trying to edit away, while Brian Dietzen gives Jimmy Palmer the good sense to tell him when to stop. Gary Cole and Wilmer Valderrama help carry the investigation as Parker and Torres, giving Knight time to work with Chloe.
A Trip for Popcorn Leads NCIS to Chloe
Monica Sims is waiting outside a bodega for her friend Michael “Sully” Sullivan when Chloe goes in for popcorn. Two men are talking in Mandarin. They have Sullivan in the back room, and Chloe hears them threaten to kill him if he won’t talk. She leaves without giving the men any reason to think she understood them. Sullivan’s body later turns up in public, and a voicemail from Monica sends Knight and Parker to her apartment.
They find Chloe hiding beneath the sink with her mother’s phone. Monica left during the night and told Chloe to call 911 if she didn’t come back. Knight gets her to come out, and Chloe’s description of the shop leads the team to its security footage. The footage puts Sullivan inside the bodega and gives the agents a chance to ask Chloe what she remembers. It takes a conversation with Knight to establish just how much she heard.
Knight Gives Chloe a Reason to Speak Up
Chloe learned Mandarin from her late father. Speaking it with Knight gives her a way to talk about him as well as the case. Knight remembers learning Mandarin from her own father, and the two share popcorn while they look through photos. The scene works because Law lets Knight enjoy talking with Chloe. The agent has questions to get through, but the girl can tell Knight is interested in the answers that have nothing to do with the murder.
Chloe agrees to help identify the men and eventually recognizes Thomas Lau, a retired detective whose photo wasn’t among the suspects she was shown. By the time the team can pursue him, Lau is dead. A wound consistent with a military knife points suspicion toward Monica, and a fresh Ghost Dragons tattoo makes Lau look like a recent recruit. Then Monica calls her own phone, learns Chloe is safe with Knight and directs the agents back to the bodega. She intends to finish what she started.
“Speechless” Ending Explained: How Does NCIS Find Monica?
At the shop, the owner explains that he and Lau were impersonating the Ghost Dragons to extort businesses. Lau’s cousin Fred Young joined them and took the operation further. It was Fred who killed Lau. Meanwhile, an undercover contact warns Torres that the real Ghost Dragons are coming after the impostors. Fred has been recruiting openly enough for the team to know where to go, and Monica heads for the same address.
Fred takes Monica at gunpoint. Once the recruits realize the real gang is coming and federal agents are already there, his backup starts to disappear. Monica gets free in the confrontation and helps Knight stop Fred from escaping. The threat of a gang war gives the final stretch urgency, although the rapid succession of tattoos, rival crews and betrayals makes the case busier than it needs to be. The ending finds its footing again when Monica and Chloe are reunited. Monica wants her daughter to teach her Mandarin, and Knight offers to practice with Chloe whenever she likes.
Does McGee Keep Mateo Out of Prison?
Mateo Garcia (Patrick Keleher) faces up to ten years for hacking the NCIS database after being blackmailed. McGee wants the court to take the circumstances into account, and he asks his colleagues to read the speech he’s written. Parker, Knight and Torres hesitate to tell him how stiff it sounds. Palmer finally says it plainly, then asks McGee what he actually wants for Mateo. The answer is simple: a chance to turn his life around.
With Palmer there for support, McGee sets aside the draft. He talks about Sullivan, who left gang life behind and mentored young people, and about Parker and Torres, who came through difficult childhoods. The judge offers Mateo a one-time alternative to jail: enlisting in the Navy. The episode leaves the speech itself offscreen, which takes some force out of the payoff. Still, Murray makes the relief land when McGee tells the team. He went into court hoping the judge would see a future for Mateo, and he comes back able to imagine it himself.
