The Fall of the House of Usher: Why does Roderick refuse to believe Pym's findings?

In the sixth episode of "The Fall of the House of Usher" titled "Goldbug," Roderick Usher refuses to believe the findings presented by Pym regarding Verna's true identity. Pym, after Victorine's apparent murder-suicide, discovers documentation that links one of Verna's disguises, Pamela, to the Usher family. Pym investigates further, trying to locate Verna and validate her connection to the Ushers. However, his search leads to dead ends, with no evidence of Verna's existence or any venues where she supposedly appeared. Despite Pym's efforts, Roderick dismisses the evidence, claiming that he could forge such pictures himself. He chooses to ignore the truth, possibly due to his escalating vascular dementia or his belief in the ghosts haunting him. Roderick even disregards the claims made by his deceased children, who allegedly revealed the path leading to their deaths after their passing.Meanwhile, Tamerlane Usher, Roderick's daughter, experiences her own journey of confusion and uncertainty. She is sleep-deprived and abandoned by her husband, Bill. Tamerlane tries to launch her new wellness subscription service, Goldbug, but faces numerous setbacks and hallucinations. She repeatedly sees Candy, one of Verna's disguises, and begins to lose her grip on reality. During her presentation, Tamerlane witnesses Candy replacing her face in the slideshow, and the screens display images of what appears to be a sex tape involving Candy, herself, and Bill. Overwhelmed with horror, she throws her microphone at Candy, accidentally hitting Juno, who had come to support her. Tamerlane's turmoil intensifies as she smashes mirrors that reflect Candy's image instead of her own. The question arises whether Candy is truly tormenting Tamerlane or if Candy is a projection of Tamerlane's own fears and desires.Lastly, Frederick, another member of the Usher family, continues to mistreat Morelle, his wife. He becomes paranoid about her alleged infidelity and refuses to acknowledge the suffering of his siblings. Frederick feeds Morelle a paralyzing medicine and interrogates her relentlessly about her relationship with Prospero. It becomes evident that Frederick's mental state is deteriorating, and he is not in his right mind. After Tamerlane's death, he no longer believes that being a full Usher offers any protection.The reason behind Roderick's refusal to believe Pym's findings can be attributed to various factors. Firstly, his deteriorating mental health, specifically his vascular dementia, may be clouding his judgment and causing him to reject the truth. He may be experiencing hallucinations and auditory distortions, leading him to question the authenticity of the evidence presented by Pym. Additionally, Roderick's strong belief in the supernatural and his children's supposed communication from beyond the grave could influence his skepticism. Roderick's refusal to accept the truth may also be driven by fear and a desire to protect himself from the implications of Verna's presence and her connection to the Usher family. Ultimately, Roderick's stubbornness and denial pave the way for further chaos and destruction within the Usher household.
