Ep 4. Possession

Perception Season 3 Episode 4: Possession

In this episode of Perception, Dr. Daniel Pierce is reminded of his own dark past when a young woman named Lili contacts him for help. She believes she's being possessed by a demon and begs him to perform an exorcism. Pierce, as a cognitive neuroscientist and a former priest, is sceptical of Lili's claims of possession. However, he agrees to investigate the situation further.

Pierce discovers that Lili has a history of mental illness and that her mother had also exhibited similar delusions before committing suicide. Meanwhile, Moretti, Daniel's former student and FBI agent, is struggling with her own demons as she faces the aftermath of a traumatic event in the previous episode.

As Pierce delves deeper into Lili's past and her family history, he begins to suspect that her mental illness may be related to a genetic mutation. He seeks the help of a geneticist to confirm his suspicion. However, Lili's father does not want to pursue any genetic testing, hoping to protect the family's reputation.

Things take a turn for the worse as Lili's condition deteriorates, and she starts showing signs of violence and aggression. Pierce becomes more and more convinced that her behaviour is not due to demonic possession but rather a severe manifestation of her illness.

As Pierce works to convince Lili's father to pursue genetic testing, Moretti tracks down the source of her own trauma, revealing a link between her case and Lili's.

The final scene of the episode reveals a shocking twist, leaving viewers on the edge of their seats and eager to see what happens next.

Overall, this episode explores the concept of possession and mental illness and how they can be intertwined. Pierce's background as a former priest and his scientific knowledge make him uniquely equipped to investigate such cases, making for an intriguing storyline. The episode also delves into the personal struggles of Pierce's colleagues, adding another layer of complexity to the show. Fans of Perception will not be disappointed with this gripping installment.
