Two men from the movie Outbreak forcefully take Castle into a secret tent. Beckett’s already there (doesn’t she always beat him?), standing between two very closely positioned benches. It’s hard to tell whether this is heaven or hell for them. The camera work here is shaky and jarring, because this is no ordinary episode, people. In fact, we’re going back in time, a whole 36 hours earlier...  

A Time When a Stripped Cab Was Eerily Parked Near a Warehouse: The cab driver, Amir Alhabi, is dead inside said warehouse. What looks to be a robbery-homicide is complicated by the wounds. In addition to a bullet in the head, each of Amir’s fingers was broken one by one. Because of the handy dandy GPS system, they know Amir (a Syrian immigrant with U.S. citizenship) shut his meter off at 10:02 the night of the murder and drove to Washington Heights. He stayed there with the motor running for six minutes and then proceeded to the warehouse. Amir called his wife right before the trip and also typed this into a notebook app: C4121652. Cryptic much? (As Ryan is explaining all of this, Beckett is looking at her phone, sad and distracted in a way that can only mean Josh’s days are numbered.) Let’s get to the...    

Family Business: Nazihah, Amir’s wife, says her husband was worried about money lately because of their daughter’s medical issues. Amir’s cousin and business partner, Jamal, tells C&B that Amir drove the taxi and rented shifts to two other drivers, Kevin McCann and Demetri Voldoff. For Jamal, however, the taxi medallion was strictly an investment; he owns a moving company. By the way...

Leeman Jones Stripped the Cab and Sold the Parts, But He’s No Killer: “I don’t hurt people...I’m just a car guy!” Jones did see someone else at the scene, though, someone who was tearing up the cab’s upholstery before bolting. Meanwhile, C&B confront cab driver Kevin McCann, who got into a fight with Amir a couple of days earlier. McCann says he was just annoyed Amir was charging him so much for rent since his boss carried around, oh, five thousand dollars or so in cash. Next weird development which suggests Amir was perhaps more than a taxi driver: His taxi had cameras and microphones in it, and the guy Jones spotted at the scene removed the hard drives with all the footage. And Amir had the cameras installed himself. Believe it or not...

It Gets Weirderrrr: So. Ten grand was deposited in Amir’s account five days prior to his murder. Then, the day of his murder, he drove a man named Fariq Yusef in a circle for a half an hour. When C&B confront a rather cold Yusef in the street, he’s carrying the possible murder weapon, but reveals himself as the Head of Security for the Syrian Consulate and alibis out. Around this time, Castle realizes those numbers Amir wrote down are the address of a storage facility in Washington Heights. C&B go there and find plastic explosives in Amir’s unit (C412). Beckett suddenly starts screaming into her phone about being exposed to radiation, and then...

Possible Radiation Poisoning Brings Two People Together: It’s 36 hours later, and C&B are quarantined. Mark Fallon of the Department of Homeland Security arrives at the precinct to help Captain Montgomery out, and he’s kind of an ass. Esposito and Ryan discover that Amir had a degree in electrical engineering and at one time worked on a weapons program for the Syrians.

Back at the tent, Beckett opens up to Castle about her troubles with Josh (who’s Haiti-bound) and how she needs someone who can really be there for her, and is she kidding right now? Just as Castle’s about to speak up, they’re released. Traces of Cobalt 60 were in the storage unit (not enough to cause health problems), which Montgomery believes came from a second crate containing a dirty bomb. And that crate and bomb, of course, are missing. Then we come to...

The Most Uncomfortable Interrogation Ever: Seriously. Since the whereabouts of this bomb are unknown, and the consensus is wives know everything about their husbands, Nazihah is brought in for questioning. Agent Fallon calls her baby, whom she’s holding in her arms a “money pit,” and starts screaming about taking her away. The baby is crying, Nazihah is crying, and Beckett looks like she wants to hit Fallon and then cry. Fallon releases Nazihah, who insists she’s innocent, and then bugs her house.

Meanwhile, that ten grand in Amir’s account was wired through six different banks under the name James Smith. It originated in Afghanistan. Oh, and the dirty bomb? Amir’s cousin/business partner, Jamal, rolled it out of the storage unit a few hours before C&B got there. Also...

Mark Fallon Continues Being Mark Fallon-ish About Everything: Fallon very quickly deduces that Jamal hired Amir to build the bomb and then killed him. One of the trucks from Jamal's moving company is missing. He also recently purchased a burner phone. Despite all of this evidence, Castle begins to smell a conspiracy. Why did Jamal look so relaxed? Why would they wire money through an Afghan bank used by military personnel? Could all of these clues have been planted to make Amir and Jamal look guilty? Castle goes to speak with Yusef, the man of mystery, who says Amir didn’t know where the money in his account came from, meaning he wasn't paid to build a bomb. Fallon kicks C&B off the case for this meeting. Can we just say...

What. An. Episode: Using the driving data from the taxi, C&B figure out that Kevin McCann’s last shift included two stops — the storage facility and the warehouse. Not a good look for Kevin. As they’re working on this, Jamal’s missing truck is found and a text is sent from his burner phone: “The package has been delivered.” Subtle. Fallon, Montgomery & Co. find the truck, but it’s empty. C&B, meanwhile, head to the warehouse and find a white van that’s not so empty. There’s a dirty bomb ticking away, in fact. An intense shoot out begins with the bad guys, and Castle stumbles upon Jamal’s dead body inside a freezer, where he and Beckett are trapped. The white van is stripped down to black, and the driver takes off. We have post-episode anxiety and need a trip to The Oasis of Serenity.
