The episode opens with a grim news report detailing the escalating crisis: hospitals are overwhelmed with patients suffering from high fevers, presumed to be caused by the Hapna virus. The world is on the brink of collapse, with essential services shutting down and society descending into chaos.

Leland, Axel, and Doug arrive at the Astor family mansion, where they meet Dr. Millie, the family doctor who has not seen Leland in some time. Despite the impending apocalypse, Dr. Millie breaks doctor-patient confidentiality and confirms that Dr. Skinner underwent surgery to implant an artificial heart at this secretive facility. However, she reveals that Skinner had the data from his heart monitoring device made untraceable upon discharge, so his current location remains unknown. Before they leave, Dr. Millie provides Leland with a copy of the firmware from Skinner's heart monitor, hoping it might reveal if a third party is tracking Skinner's health data. She also requests that if the team ever finds Skinner, they bring him back to the facility for care.

Back at Lazarus headquarters, Leland begins to confess that he has been acting as a mole within the team, but Axel interrupts, revealing they already knew about his betrayal. Eleina examines the firmware and discovers that while Skinner's heart monitor is active, it does not provide his location. However, she finds that the heart is being monitored from Pakistan, which coincides with the location of Popcorn Wizard, a hacker introduced in episode five. Eleina persuades Doug to accompany her to Pakistan to track down Popcorn Wizard and obtain Skinner's exact location.

Meanwhile, Leland reveals more about his background: he is the illegitimate son of a wealthy aristocratic family, the Astors, and has not seen his older sister Isabella in four years. He visits Isabella at the family mansion to request access to the secret hospital network patronized by their family, hoping to use it to find Skinner. Isabella is cold and distant but admits she misses him. She agrees to help but insists Leland spend a weekend with her, which he promises to do after the day they believe everyone is supposed to die, giving them hope for more time.

As the episode progresses, the team pieces together that Skinner's artificial heart surgery was performed at a highly exclusive hospital for the wealthy, and the heart's monitoring system is being covertly tracked. This revelation is their best lead yet in locating Skinner and potentially finding a cure for Hapna.

The episode culminates with the arrival of the assassin known as the Phantom Killer, who dramatically jumps off an overpass onto a freeway, unharmed by the fall or the speeding traffic. This assassin has been hired by powerful forces opposing Lazarus and is now targeting Axel, escalating the danger for the team.

The episode ends on this tense cliffhanger, with the Lazarus team racing against time to use the new information from the firmware and Leland's family connections to find Skinner before the global catastrophe unfolds.

The ending of Lazarus Season 1, Episode 10, "I Can't Tell You Why," concludes with the Lazarus team uncovering a crucial lead about Dr. Skinner's secret heart transplant and the monitoring of his artificial heart from a location in Pakistan. Leland reconnects with his estranged sister Isabella, promising to spend time with her after the team's urgent mission. Meanwhile, the threat to Axel intensifies as an assassin known as the Phantom Killer is hired to eliminate him, setting up a tense cliffhanger.

In a detailed, scene-by-scene narrative:

The episode opens with a grim news report showing hospitals overwhelmed by patients suffering from high fevers, presumably caused by the Hapna epidemic. This sets a dire tone, emphasizing the escalating crisis affecting society.

Leland, Axel, and Doug arrive at a grand family mansion to meet Dr. Millie, the family doctor. Dr. Millie confirms that Dr. Skinner underwent an artificial heart surgery at her facility but cleverly erased all traceable data upon his discharge, making his current location unknown. She provides the team with firmware from Skinner's heart monitor, hoping it might reveal if a third party is tracking his heart data. Dr. Millie requests that if Skinner is found, the team should bring him to her for care.

Back at Lazarus headquarters, Leland begins to confess his role as a mole within the team, but Axel reveals they were already aware of this betrayal. Eleina analyzes the firmware and discovers that Skinner's heart monitor is active but does not reveal his exact location. However, she identifies that the data is being monitored from Pakistan, the same place where the hacker Popcorn Wizard was previously tracked. Eleina convinces Doug to accompany her to Pakistan to locate Popcorn Wizard and potentially find Skinner.

Parallel to this, Leland reconnects with his older sister Isabella at the Astor family mansion. Their reunion is emotionally complex; Isabella is cold but reveals she genuinely misses him. She provides information about the family doctor and presses Leland to spend a weekend with her, which he agrees to, scheduling it for the day after the team expects the first death from Hapna, hoping for more time.

The episode also reveals that Leland has been acting as a mole, feeding information to powerful adversaries who want to dismantle Lazarus. This adds tension within the team and raises the stakes.

The climax features the arrival of the Phantom Killer, a notorious assassin hired to eliminate Axel. He makes a dramatic entrance by jumping off an overpass onto a freeway, unharmed by the fall or the traffic, which halts in shock. This sets up a dangerous confrontation for the next episode.

In terms of character fates at the episode's end:

• Leland is alive, having reconnected with his sister and continuing his conflicted role as both team member and mole.
• Axel is alive but now targeted by the Phantom Killer, placing him in immediate danger.
• Doug and Eleina prepare to travel to Pakistan, pursuing the lead on Skinner's location.
• Dr. Skinner remains missing but is confirmed to have a secret artificial heart being monitored remotely.

The episode closes on a tense note, with the team gaining a vital lead but facing imminent threats, emphasizing the ongoing conflict between Lazarus and the powerful forces opposing them.

Based on available sources, there is no evidence of a post-credits scene in Lazarus, Season 1, Episode 10, "I Can't Tell You Why" (2025). The episode's narrative concludes with the team--Leland, Axel, and Doug--gaining access to a secretive, high-end medical clinic through Leland's family connections, in hopes of tracking Skinner via his artificial heart's monitoring data. The emotional climax centers on Leland's strained family dynamics, particularly with his sister Isabella, as they navigate outdated notions of inheritance and power within their wealthy family. The team's visit to the clinic reveals that Skinner did receive an artificial heart, but the tracking data is encrypted, leaving them at a dead end for now. Meanwhile, the assassin from the previous episode makes a dramatic, over-the-top entrance, leaping onto a freeway in a cliffhanger that teases more action in the next installment. None of the detailed recaps, reviews, or official episode descriptions mention any additional scenes after the credits roll. The episode's final moments are focused on the immediate fallout of the clinic visit and the assassin's arrival, with no indication of a post-credits sequence that reveals new information, teases future plotlines, or provides closure to lingering questions.

Episode 10 reveals significant new information about Dr. Skinner, including details about his medical history and his role related to the Hapna epidemic. The episode's final third provides a satisfying conclusion to the breadcrumb trail about Skinner that the series has been building, making his character and motivations clearer to the audience.

The episode opens with a news broadcast showing the dire stakes of the Hapna epidemic, with hospitals overflowing with people developing high fevers. This sets a realistic tone for the crisis, showing that people only start to believe the severity of the epidemic when they see widespread illness.

Leland takes Axel and Doug to his home to secure them an invite to a private clinic connected to Skinner's medical history. His backstory as a bored rich kid who turned to crime is explored, providing a satisfying conclusion to his character arc, though it makes him less likable to some viewers.

Axel, along with Leland and Doug, is involved in securing access to a private clinic linked to Skinner's medical history. The episode also features a dramatic arrival of an assassin, setting up for action in the next episode. The team continues to follow leads to find Skinner and a potential cure for the Hapna epidemic.

Episode 10 is described as a slow-burn and actionless compared to previous episodes, focusing more on revelations and character backstory. While some viewers found it boring, the payoff in the final third with important reveals about Skinner was considered worth the slower pace.

Based on available information, Lazarus Season 1, Episode 10 "I Can't Tell You Why" (2025) is not considered family friendly and is rated TV-MA, indicating it is intended for mature audiences. While detailed scene-by-scene breakdowns are not available, general content guidance and the show's tone suggest several elements that may be upsetting or inappropriate for children or sensitive viewers:

• The episode opens with a news broadcast depicting a global health crisis, with hospitals overwhelmed by patients suffering high fevers, creating an atmosphere of widespread panic and societal collapse. This could be distressing for viewers sensitive to real-world parallels or depictions of mass illness.

In summary, "I Can't Tell You Why" deals with mature themes of global catastrophe, contains moderate violence and language, and maintains a consistently intense, emotionally charged atmosphere.
