Uncle Fester is no ordinary uncle. Besides being creepy, eerie, and deranged, he is Wednesday Addams’ super weapon. In one of the most wacky and conspiracy-laden plot twists in Wednesday Season 2, Uncle Fester takes center stage and performs an outrageously effective undercover operation in gothic history. It seems Fester is charged with the infiltration of the foreboding Willow Hill psychiatric institution, where he does not creep in but pushes his way inside in an overly dramatic fashion to the point that he becomes an inmate. Here we explore the details of why and how Uncle Fester came into Willow Hill and what the result was.
The mission to find “LOIS”

Uncle Fester did not just happen to walk into the Willow Hill Psychiatric Hospital. His arrival was a rather calculated, dramatic, and lunatic move set up by Wednesday herself. After discovering the obituaries of some outcasts who were not only patients at Willow Hill but also long assumed to be dead, with all clues pointing towards the mysterious “LOIS,” Wednesday seeks the help of Fester, using his peculiar nature as a ticket for their way inside the psych ward. Fester also reveals that he had been to Willow Hill in his childhood, and that Morticia's sister, Ophelia, was also a patient there. The fact that Morticia did not disclose what happened to Aunt Ophelia creates momentum in their quest and makes the unseen even more poignant.
From Apple Hollow to Willow Hill: The elaborate planning

Fester proceeds to fulfill the plan in a spectacularly exaggerated fashion. At first, he intentionally creates disorder through his trash-talking and strange mannerisms at the Apple Hollow Inn. He checks in at their biggest and most expensive suite with ink-drenched cash and a fake ID under the name “Fester Diabolik.” His ridiculousness works to his advantage: he vandalizes his room and makes annoyingly loud noises, provoking other residents to complain against him. Thus, he gets himself arrested and subsequently sent to the insane asylum of Willow Hill.
At the police station, the officers are stunned by his impressive collection of passports and driver's licences, to which Fester replies, “I love to travel, it's my passion.” He even eats a cactus from the sheriff’s desk, each bizarre stunt strengthening the illusion of his mental disorder and paving the way for a rather successful infiltration. It is with this planned chaos that Fester turns into a patient at Willow Hill instead of an insider so that he can pass through security checks without the procedures that a normal outsider would. Wednesday's plan was highly dependent on her uncle's knack for the strange; after all, Fester is the unflinchingly odd member of the Addams family.
Behind the walls of Willow Hill

As soon as Fester gets admitted to Willow Hill, he carries out his job perfectly. His comical behaviors, like flirting with the lunch lady or mixing up names (thinking Louise is Lois), are mere brushstrokes over his true goal: to find Augustus Stonehurst and who Lois is. Fester discovers Stonehurst, and after shock-interrogating Stonehurst's parrot, he learns the numeric code 51971, which opens the maintenance closet where the hidden cells are located. And later on, Fester, through Thing, gives the crucial piece of information to Wednesday that Stonehurst, a former science teacher at Nevermore and a current patient at Willow Hill, signed the death certificates of the missing outcast patients. With that information in hand, Wednesday and Fester plot to infiltrate the facility and expose who or what LOIS is.
The outcome

The infiltration of Fester eventually leads the uncle-niece duo to unmask the way Willow Hill actually operates. With the coded information Fester received from Stonehurst's parrot, he and Wednesday break into the secret LOIS (Long-term Outcast Integration Study) research labs, in which the outcasts declared dead are locked up to conduct experiments. The access and dramatization without Fester would have seen the plan of Wednesday fail at the security gate. If it were not for Fester, Wednesday's plan would have failed at the security gate.
After getting in, they get discovered, causing large-scale chaos. During the chaos, along with Fester’s anarchic distraction, the prisoners are liberated, and a series of explosive activities take place within the facility. Although Fester's admission to the Willow Hill Psychiatric Hospital seemed like a farce at first, it ended up bringing Willow Hill’s dark side to light and towards a violent, supernatural climax.
We hang in the darkness with the cliffhanger that Wednesday Season 2 Part 1 left us with. Fortunately, Netflix will be releasing the rest of the episodes; we just need to be more patient.
