In the gripping third episode of the second season of "Based on a True Story," titled "Relapse," the show delves deeper into the psyche of its characters, particularly Ava, as she grapples with the resurgence of the Westside Ripper murders. The episode is a thrilling ride that keeps viewers guessing, as the line between reality and paranoia blurs, and the truth proves to be as elusive as ever.
The episode begins with a haunting scene, setting the tone for the psychological thriller that unfolds. A woman's desperate plea for help is met with a brutal stab, and the chilling revelation that Matt, the supposed reformed serial killer, is the one wielding the blade. However, this turns out to be a nightmare of Ava's, a sign of the lingering doubt and fear that plague her waking hours.

Ava's nightmare is juxtaposed with the reality of a new murder in the news, one that bears the hallmarks of the Westside Ripper. Her suspicion immediately falls on Matt, leading to a tense confrontation. Matt's claim of innocence, backed by Tory's confirmation of his alibi, does little to assuage Ava's doubts. This scene is a testament to the show's ability to create tension and suspense through character dynamics and the uncertainty of truth.
As Ava becomes increasingly obsessed with proving Matt's guilt, she enlists the help of her new friend Drew, unaware of the irony that Drew is a homicide detective with her sights set on the Westside Ripper. Ava's decision to plant a nanny cam in Tory's apartment is a testament to her determination, albeit an ethically questionable one. The ensuing spy caper, where Ava and Nathan follow Matt to an ax-throwing venue, adds a touch of dark humor to the episode, highlighting the absurdity of their situation.
The subplot of Nathan's tennis career provides a brief respite from the main storyline, offering a glimpse into his character's past and his struggle to find relevance in his present. His decision to bid all their savings on a chance to play against his former rival is a moment of recklessness that contrasts with Ava's calculated pursuit of the truth.
The episode takes a surprising turn when Ava, in her role as an amateur detective, sneaks into the latest crime scene and discovers Drew there, dressed as a detective. This revelation is a masterstroke, adding a new layer of complexity to the narrative. Drew's admission that she is a homicide detective and her dedication to catching the Westside Ripper casts a new light on her relationship with Ava, suggesting that there may be more to their friendship than meets the eye.
As the episode progresses, Ava's investigation leads her to the conclusion that they are dealing with a copycat killer, one who mimics the styles of different serial killers. This realization is both a triumph for Ava and a chilling insight into the mind of the new murderer. The episode concludes with a ominous note, as a mysterious figure is seen watching Ava through her basement window, suggesting that the danger is closer than she thinks.
"Relapse" is an episode that excels in its ability to weave a intricate web of lies and deceit, while keeping the audience on the edge of their seats. The episode's strength lies in its character development, particularly Ava's descent into obsession and her growing paranoia. The introduction of a copycat killer adds a new dimension to the story, promising a season filled with twists and turns.
In conclusion, "Based on a True Story" continues to deliver a compelling narrative that keeps viewers guessing. The third episode, "Relapse," is a testament to the show's ability to blend dark humor with psychological suspense, creating a unique viewing experience. With its engaging plotlines and compelling character dynamics, the episode sets the stage for an intriguing season ahead.
