In the sixth episode of The Night Agent, titled "Fathoms," the tension escalates as Peter Sutherland races against time to uncover the truth behind a conspiracy that reaches the highest levels of government. Following the shocking revelations from the previous episode, where Peter and Rose deduced that the Vice President was behind the metro bombing, the stakes are higher than ever. This episode not only deepens the intrigue but also reveals the treachery lurking within the White House.

The episode opens with Peter determined to inform Diane Farr, the Chief of Staff, about his findings. However, he is acutely aware that bringing Rose to the White House could put her in danger. With the Vice President complicit in the conspiracy, Peter suspects that there is a mole within the White House who is feeding information to the Vice President and his accomplices. To keep Rose safe, Peter decides to leave her with his friend Cisco, a trooper who reluctantly cancels his date to help his friend.
As Peter arrives at the White House, he attempts to piece together the events surrounding Maddie Redfield's kidnapping and the metro bombing. Diane, however, is preoccupied with the chaos caused by Maddie's abduction and struggles to connect the dots. Peter reveals that evidence from the Campbells' hard drive indicates a much larger explosion was planned, one that could have resulted in catastrophic loss of life had he not intervened on the train. This revelation hints at a sinister plot that goes beyond Maddie's kidnapping.
The tension mounts as Peter realizes that the Vice President and CEO Gordon Wick of Turn Lake Industries are orchestrating a much more significant attack. Diane urges Peter to be cautious with his accusations, but in a slip of the tongue, she reveals that she knows about his trooper friend watching over Rose. This moment of carelessness exposes Diane as the mole, confirming Peter's suspicions that she has been feeding information to the Vice President and Wick all along.
In a desperate attempt to maintain control, Diane calls Wick and plots to have Peter arrested on false charges while ordering the assassination of Rose. However, Peter manages to escape the White House just in time. Meanwhile, Dale and Ellen, the assassins, are dispatched to eliminate Rose. They track down Cisco and Rose, leading to a harrowing car chase. Tragically, Dale kills Cisco, prompting Peter to confront him. In a moment fueled by rage and grief, Peter kills Dale, marking a turning point in his character as he grapples with the consequences of his actions.
As the episode progresses, Peter becomes the prime suspect in Maddie’s kidnapping, thanks to Diane's manipulations. Agent Badger from the White House informs Arrington and Monks that Peter is the main suspect, further complicating Peter's situation. The Vice President, still in the dark about his daughter's whereabouts, is convinced by Diane that Maddie's kidnapping could serve as a cover for their scheme. Despite his initial resistance, the Vice President has little choice but to align himself with Diane and Wick to protect his own interests.
Peter, now on the run, takes refuge on his godfather’s boat with Rose. Here, they find a moment of solace as Rose tends to Peter’s wounds from his earlier confrontation with Dale. However, their peace is short-lived as the radio broadcasts the Vice President's public speech, accusing Peter of abducting Maddie. This moment serves as a crushing blow to Peter, who once envisioned himself as a loyal agent dedicated to protecting the nation. Instead, he finds himself entangled in a web of lies and deceit, with the very people he trusted betraying him.
The episode concludes with Peter reflecting on the harsh reality of his situation. The foundation of the agency he believed in is crumbling, revealing a landscape rife with treachery. As he grapples with the unfounded allegations against him, Peter is left questioning whether he can still defend the nation from those who have turned against it. The episode ends on a cliffhanger, leaving viewers eager to see how Peter will navigate this treacherous landscape and whether he can uncover the truth behind the conspiracy before it's too late.
"Fathoms" is a pivotal episode that not only heightens the stakes for Peter and Rose but also deepens the narrative complexity of *The Night Agent*.
