Evan races across Downtown but arrives too late. Katrin’s GPS signal remains offline. At the loft, he finds the door open, an overturned barstool, a smashed burner phone, and a few drops of blood. He leaves, driving back to Memo’s house. He finds it empty, and Memo is gone. Evan drives away.

Wondering how Slatcher located the loft, Evan suspects he tracked his vehicle. Evan pulls into an alley and scans his car with his nonlinear junction detector. When the sweep yields nothing, he smashes the detector itself and finds a tiny transmitter hidden inside the wand’s handle. Evan realizes the unparalleled “tradecraft” of using the very tool designed to detect as a detector. He drops the bug into a dry-cleaning van’s gas tank to create a false trail and confuse Slatcher and his team.

Evan concludes that Slatcher planted the device in Chinatown while he was in the sniper’s apartment, meaning every location he drove to afterward is compromised: the loft, Morena’s aunt’s house in Vegas, and Memo’s house. Only his penthouse at Castle Heights and Tommy Stojack’s workshop remain safe. Evan understands now why “Orphan Zero” was the best.

Back home, Evan reviews surveillance footage showing Slatcher and Candy McClure breaking into the loft. Slatcher subdues Katrin with a backhand, and Candy smashes the phone with her boot before they carry her out in seconds.

Evan calls Slatcher. The two identify themselves as “ORPHAN 0” and “Orphan X”, and Evan demands to speak to Katrin. She comes on the line, apologizing for failing to handle the dead bolt. Evan reassures her and promises to find her. After she hands the phone back to Slatcher, the two former “Orphans” discuss their methods. Slatcher confirms he planted the bug in Chinatown. Evan wonders why he is after him and thinks of potential enemies. Slatcher says his clients want to remain hidden. Slatcher hints they may have started with someone inside Evan’s building to trace him—a claim Evan notes but dismisses for the moment.

While they talk, Evan watches through his surveillance cameras as Candy storms Joey Delarosa’s apartment across the street and locates the hidden bridge phone in his wall. Slatcher, realizing Evan has already masked the call’s origin, declares his new strategy: make Evan come to him. They agree to prepare to meet each other and end the call. Evan considers the GPS microchips in Katrin’s stomach as his advantage. She has perhaps one or two days before the sensors pass through her system and then she is lost.

At his temporary base in an unrented office building near Calabasas, Slatcher uses advanced comms gear to text his employer, the figure known only as Top Dog. He reports they have Katrin and will use her as bait. Top Dog asks about Orphan V’s performance; Slatcher confirms that Candy is doing well, though the freelance mercenaries are proving unreliable. Top Dog notes that “Orphan X” is smarter than many and signs off.

Slatcher surveys his new hires—dishonorably discharged soldiers he intends to use as a protective “shield of killers” (240). Candy emerges from a utility room after checking her jugs of hydrofluoric acid, suggesting they should visit Katrin, who is shackled to a desk in an empty office.

Slatcher reveals to Katrin that Sam is alive. They faked his death to make Katrin’s grief authentic and manipulate Evan. Slatcher tells her that Sam’s survival, he tells her, depends on her full cooperation. Katrin agrees, saying she wants this to end, but Slatcher notes it will only end with Evan’s death. After Slatcher leaves, Candy stays to taunt Katrin, warning that she hopes she won’t cooperate because Candy is eager to erase people.

Lying awake in his penthouse, Evan replays his conversation with Slatcher. Though he dismisses the claim about having someone inside Castle Heights as misleading, uncertainty gnaws at him. He is haunted by images of Katrin—the blood on his loft floor, the shattered phone, her desperate plea and his promise to find her.

He waits for the GPS ping from Katrin’s microchips, but a signal never comes. Unable to find peace, he moves to his meditation spot. For the first time in his life, he cannot meditate.

By morning, Evan has completed a full security check and still received no GPS signal from Katrin’s microchips. He destroys his old SIM card, shifts his phone service to a provider in Marrakech, and sets up an untraceable GSM base station on the roof. When Hugh Walters, the homeowners’ association president, discovers him, Evan claims to be an amateur astronomer. Hugh mentions that Mia Hall seemed scared earlier and suggests Evan check on her at the upcoming HOA meeting. Evan recalls Mia’s claims about a work crisis.

Evan ultimately attends the meeting. After a while, he observes Mia looking nervous and lost. Soon, she receives a call and immediately leaves. Evan follows her out, and she claims her brother called her to pick Peter up. He knows this is a lie; from his surveillance, he knows her brother’s ringtone is different. He offers to help her but she says he cannot. Evan follows Mia to the parking garage, where Johnny Middleton confronts him, armed with brass knuckles and a fighting knife. Instead of attacking, Johnny apologizes to Evan.

Johnny breaks down crying. He explains that he broke an opponent’s nose during combat training, and the man’s three older brothers tracked him down to Castle Heights. Frustrated by the delay but concerned for Johnny, Evan agrees to help. They meet the three brothers outside the building, including Reza, who wears a protective nose splint. Evan attempts to talk to them, warning them that stress hormones are compromising their judgment. The oldest brother dismisses him as they circle Evan and attack.

Evan systematically neutralizes all three using only defensive techniques—blocks, deflections, and counters that turn their aggression against them. After the brief fight, Evan forces a mesmerized Johnny to apologize to Reza and agree to pay all the brothers’ medical bills. As Evan leaves, he warns Johnny never to speak of what happened.

Hours pass with no GPS signal from Katrin. Evan searches databases for any trail leading to Slatcher but finds nothing. He reflects on how his distrust may have endangered Katrin but ponders on his complex way of life, thinking that he cannot trust anyone since former “Orphans” are chasing him. Frustrated that he is all the more drawn into the real world, he ultimately resolves to focus on his guiding rule: never let an innocent die. On his computer, Slatcher remains untraceable.

He notices with dismay that Vera, his aloe plant, has died and the living wall is withering from the clogged irrigation system.

Suddenly, Evan’s surveillance cameras capture two men bypassing a rear security door. Facial recognition in the system identifies them as Michael Marts and Axel Alonso, recently released convicts prosecuted by Mia and now seeking revenge. Evan watches them take the elevator to Mia’s floor, then loses them when they move out of camera range. Evan wonders what to do. A balloon bumps against his bedroom window, bearing a note from Peter saying scary men are there and asking for help.

The men are inside Mia’s apartment. Evan faces an impossible choice between waiting for Katrin’s signal and helping Mia and Peter. He cannot reveal to Mia who he is. For the first time, the answer lies neither in training nor logic. He decides to help—but not through conventional means.

Evan rappels down from his penthouse and swings through Peter’s bedroom window just as the intruders threaten to break Mia’s fingers unless Peter opens the door. Peter sits frightened on the floor. Evan quietly removes the chair barricade and slips into the living room.

Evan finds Marts and Alonso restraining Mia and attacks them. He strikes Alonso, shattering his collarbone with a single hammer-fist punch, then disarms Marts and field-strips his handgun in midair. He subdues Marts with a police chokehold, pressuring him until he becomes compliant, then gives the men a choice: leave quietly or he will throw them down the trash chute from the 12th floor. They choose the elevator. He tells Mia, who is crying and trembling in pain, not to call the police and that he will return. Mia comforts Peter as they leave.

After escorting the men to their trunk, Evan drives them to a remote area off Mulholland Drive. They plead with him not to kill them and promise they only wanted to scare Mia. Evan releases them, warning that if they contact her again, he will kill them. Marts says Evan is a “scary man” and Evan drives away, leaving them to walk three miles back to the main road.

At the Calabasas building, Katrin sits weak and nauseated, zip-tied to a desk. Candy brings her food and taunts her about refusing to eat, warning that weakness helps neither her nor Sam. Katrin struggles to eat.

Evan returns to his “fortress” in Castle Heights, erases incriminating surveillance footage of the building, and goes to Mia’s apartment. She thanks him for protecting her and Peter but confronts him about his extraordinary skills in disarming the men. When she questions him about who he is, Evan tries to avoid the discussion. She presses him about his profession, asking him about his real name and reminds him of her profession’s duties. Evan asks her who called her in the HOA meeting. She says it was her boss who informed her that the threats against them had increased. Evan voices his thought that Mia moved into the building for better security, even though her husband’s insurance money was unavailable. Mia startles, questioning him about how he knew intimate details about her husband’s life insurance. Evan admits he investigates everyone as potential threats because many are trying to kill him. Mia is devastated to learn he spied on her and already knew the secrets she had confided in him. She tells him that relationships are built on trust—something he has violated. Evan feels a “pervasive sadness,” recognizing this as something he has never known.

Before Mia can decide what to do, Evan’s RoamZone pings with Katrin’s GPS coordinates. He immediately stands to leave, telling Mia to do whatever she must. As he exits, he notices a new Post-it note by her phone about choosing friends who want the best for you.

Slatcher finishes a call with Evan, setting up a meeting at midnight in the crowded plaza below and exchanging threats. Evan demands proof of Katrin’s life and her release before following Slatcher, with the condition that Slatcher come alone. Meanwhile, Slatcher is positioned in a sniper’s nest inside the two-story guitar outside the Hard Rock Cafe at Universal CityWalk, his Remington M700 aimed through the sound hole. Slatcher agrees to Evan’s demands but plans to shoot Evan on sight.

Slatcher contacts his field teams through the radio channel. They are positioned in paramedic uniforms and civilian clothes throughout CityWalk; Slatcher orders them to abort and return to base to avoid Evan identifying one of his men. Confident his position is undetectable, he settles in to wait.

Evan is not at CityWalk. Using Katrin’s GPS signal, he has located the Calabasas building and approaches it, armed with a combat shotgun. After observing Slatcher’s team return to base, he recognizes his advantages: Slatcher is absent, and no one expects him here. Evan surveys the building closely, seeing Candy and eight other men. He locates Katrin’s room and starts his operation.

Evan plants a stun grenade on the breaker box. When it detonates and cuts the lights, he blows a rear door in the western wing and charges inside. Evan fires a warning shot that drives four men away from Katrin’s room. Then Candy McClure bursts from a utility closet, firing. They grapple at close range until Evan kicks her backward into the closet, where she crashes into the jugs of hydrofluoric acid. Her screams become almost inhuman as the acid dissolves her flesh. Evan traps her inside by wedging a spent shell casing under the door.

Evan sprints toward the lobby, destroying the remaining operators. In her cell, Katrin covers her ears, unable to escape the sounds of violent death. Evan kicks in her door and cuts her free. The men outside prepare for a counterattack. As Evan reassures Katrin, she asks him if he killed Slatcher. He denies it, and his phone rings—Morena Aguilar calling from Las Vegas, angrily confirming she found someone he should help, which means Katrin orchestrated the Memo Vasquez setup through her.

The realization hits too late. As Evan turns, Katrin stabs him in the abdomen with his own knife.

Blood runs from Evan’s wound, spilling his shirt. Katrin backs away, sobbing and apologizing, as she says that Slatcher forced her to plot against Evan by threatening Sam. Evan realizes Morena’s call made him turn at the last instant, preventing a fatal wound, but he is still gravely injured. Evan turns away to leave.

Using the shotgun as a crutch, Evan staggers through the corridor and, calculating his movements, he escapes out a window onto the hillside. He then circles back toward the lobby and kills two more operatives despite the agony each recoil causes. He finally makes it to his truck. Before fleeing, he drives into the line of parked SUVs to disable their fuel pumps and impede the men from pursuing him. As he moves onto the freeway, he spots Slatcher arriving in the purple Scion, looking enraged.

Stuck in traffic and nearly unconscious from blood loss, Evan draws on a lesson from his first instructor in the barn regarding pain management. He must focus only on each breath, keeping the pain within the present moment while struggling to stay conscious and keep driving.
