In the sixth episode of "Before," titled "Fever Dream," the narrative takes a nightmarish turn as the lines between reality and delusion blur further. The episode opens with the aftermath of Dr. Eli Bauer's (Billy Crystal) drastic measures to "cure" Noah (Gideon Adlon) of the mass psychosis he inadvertently induced. The tension is palpable as Eli faces the consequences of his actions in a boardroom filled with skeptical doctors, officials, and executives, including Jane (Lesley Manville), Gail (Yara Martinez), and Denise (Andrea Fraser).

Eli's admission of performing a non-consensual, invasive procedure on Noah to extract a non-existent "worm" is met with a mix of shock and disbelief. Jane's support for Eli's actions, attributing the return to normalcy of the affected children to Noah's "cure," adds a layer of complexity to the ethical dilemma presented. The boardroom scene is a masterclass in tension, with each character's doubt, fear, and determination playing out in a delicate ballet of power and persuasion.
As the episode progresses, Eli's mental state begins to unravel. His obsession with the case and the pressure from the hospital administration take a toll on him. The visual of his research board, cluttered with images of eyes and worms, is a haunting backdrop to his deteriorating psyche. The intrusion of his wife, Barbara (Uzo Aduba), and her attempts to sell the house further exacerbate Eli's stress, leading to a heated confrontation that underscores the fractures in their family dynamic.
The episode also delves into the past, revealing the origins of Eli's relationship with Lynn (also played by Judith Light). A flashback to a younger Eli and Lynn, digitally de-aged in a scene that, while visually jarring, serves to highlight the depth of their connection, is a poignant reminder of the love and trust that once bound them. The revelation that Eli's actions may have inadvertently led to Benjamin's death adds a layer of guilt and regret to his character, complicating his motivations and actions.
The episode's climax comes as Eli, driven by his obsession, seeks out Benjamin Walker's brother. The discovery that Benjamin's chest scar mirrors Noah's birthmark is a chilling moment that suggests a supernatural connection between the two characters. This revelation propels the narrative into a realm of reincarnation and revenge, with Eli's actions potentially having dire consequences beyond his understanding.
"Fever Dream" is a turning point in the series, where the once rational Dr. Bauer is consumed by his own delusions and the weight of his past. The episode is a rollercoaster of emotions, with each scene pushing the characters and the audience to the brink of madness. The writing is tight, the acting is compelling, and the direction is masterful, creating an atmosphere of unease that permeates every frame.
In conclusion, "Before" continues to challenge its audience with "Fever Dream," an episode that delves deep into the psyche of its characters and the nature of reality itself. As the series progresses, the questions it raises about the human mind and the supernatural are as intriguing as they are unsettling, leaving viewers eager for the next installment in this psychological thriller.
