Wednesday Season 2 begins with Wednesday Addams returning to Nevermore Academy after summer break, having spent the time honing her psychic abilities using Goody Addams' Book of Spells. She and her uncle Fester infiltrate the basement of Willow Hill, a prison for outcasts, where they free several captives, including a mysterious woman who may be Wednesday's long-lost aunt, Oilia Frump. During the escape, Marilyn Thornhill frees Tyler, expecting gratitude, but Tyler violently attacks her with his Hyde claws and throws Wednesday out of a window. Wednesday is left unconscious as Tyler escapes into the night.

Wednesday wakes in a coma after Tyler's attack. Morticia reads to her from Macbeth, and Wednesday enters a dream state. Meanwhile, Isaac, Françoise, and Tyler hide in a secret bunker. Isaac attempts a blood transfusion from Tyler to Françoise to stabilize her deteriorating condition. Wednesday uses corpse moths, with Eugene's help, to track Isaac's movements since the moths return to their host body.

Hester, Wednesday's grandmother, invites her to spend the summer away from Morticia, suggesting distance might help. Principal Barry Dort reveals his plan to transform Frump Tower into a school of mortuary sciences with a body farm. Hester initially refuses but is persuaded by Bianca Barclay, who removes her siren amulet to manipulate Hester into donating her fortune to Nevermore. Hester agrees and will be the guest of honor at the upcoming Venetian Masquerade Gala.

Larissa warns Morticia that Hester is using estrangement to pull Wednesday closer and urges Morticia to tell Wednesday the truth about her connection to Françoise and Isaac before tragedy strikes. Ajax warns Wednesday and Enid that Dort may be blackmailing Bianca and her family. During a fencing match, Bianca reveals Dort's manipulation and sirens Wednesday, but Wednesday anticipated this and had Agnes DeMille nearby to witness everything. Dort's true plan is to steal Hester's fortune and flee. To cover his tracks, Dort kills Gideon.

Isaac forcibly reattaches Thing to his body, which strengthens his telekinesis. He buries Wednesday alive and leaves her for dead. Agnes, who can turn invisible, secretly follows Wednesday to the Skull Tree and witnesses Isaac's attack. Agnes finds Enid, and together they try to dig Wednesday out but fail. Enid makes the fateful choice to transform into her werewolf form under a full moon, risking permanent transformation and becoming a target for other wolves. She uses her strength to free Wednesday before running away.

Wednesday, Morticia, and Gomez race to Iago Tower to rescue Pugsley. At the lab, Isaac and Françoise betray Tyler, forcing him into a power-extraction device. Françoise, resigned to her fate, wants her son freed from his Hyde side, even if it is against his will.

At the Venetian Masquerade Gala, Principal Barry Dort's true identity as a con man and leader of the cult Morning Song is revealed. He kidnapped Bianca's mother, Gabrielle, to weaponize Bianca's siren powers and coerced Hester into donating her fortune to Nevermore. Bianca siren-calls Barry onstage, forcing him to reveal his intentions. Barry takes Bianca hostage and threatens to use pyrokinetic powers against her. Ajax intervenes by unleashing his Gorgon hair, turning Barry to stone. A chandelier then crashes onto Barry's petrified body, shattering him into pieces.

The season ends with multiple threats still looming: Judy Stonehurst's vendetta against Wednesday, Tyler's rage and escape, Slurp's evolving dangerous nature, and the mystery surrounding Oilia Frump. Wednesday's powers are gone, forcing her to rely on her instincts and friends to survive, while the vision of Enid's grave continues to haunt her decisions.

At the end of Wednesday Season 2 (2025), Wednesday Addams, along with Morticia and Gomez, rescues Pugsley from the villain Slurp (Isaac Night), who intended to use Pugsley as a power source to strip Franciose of her Hyde powers. The season closes with Tyler, the Hyde, finding a new support system in Miss Capri, who helps him transcend his need for a master, and they drive off together, setting up future developments.

The ending unfolds with Wednesday, Morticia, and Gomez embarking on a mission to find Pugsley, who was kidnapped by Slurp, revealed to be Isaac Night--the mad genius behind the outcast-reversal technology stolen for sinister experiments. Isaac plans to use Pugsley's electrokinetic powers to power a machine that will permanently remove Franciose's Hyde abilities.

The rescue mission is tense and urgent. Wednesday's psychic abilities, sharpened but unpredictable, play a crucial role as she navigates the dangers posed by Isaac Night and his technology. Morticia and Gomez provide emotional and tactical support, emphasizing the family's unity in crisis.

Meanwhile, the prophetic vision that haunted Wednesday--foreseeing Enid's death--is cleverly averted through a body swap trick, saving Enid and resolving one of the season's major conflicts.

Tyler, the Hyde who was a major antagonist in Season 1 and reappeared in Season 2, ends the season in a state of uncertainty but with a new path forward. Miss Capri, Nevermore's music teacher and daughter of a Hyde, offers Tyler a chance to join a group of people like him, helping him transcend the need for a single master. Initially resistant, Tyler ultimately accepts her help, and the season closes with the two driving away together, hinting at Tyler's potential redemption or transformation.

The fates of the main characters at the end are:

• Wednesday Addams: Physically and emotionally stronger, having saved Pugsley and averted Enid's death, she remains central to the ongoing mysteries and conflicts.
• Pugsley Addams: Rescued from Isaac Night's clutches, his powers remain intact, and he is safe with his family.
• Enid Sinclair: Saved from the prophetic death vision, her future at Nevermore is secure for now.
• Tyler: Leaves Nevermore with Miss Capri, seeking a new life beyond his previous destructive path.
• Isaac Night (Slurp): Defeated in his plan to use Pugsley's powers, his fate is left ambiguous but he is no longer an immediate threat.

This ending ties up major plotlines while introducing new possibilities, especially through Tyler's storyline and the unresolved mysteries surrounding the Addams family and Nevermore Academy.

There is no post-credits scene in Wednesday Season 2, including at the end of Episode 4, which was the last episode of the first part released on August 6, 2025. Netflix did not include any bonus footage or teaser clips after the credits to preview the upcoming episodes in Part 2, which premiered on September 3, 2025.

After being freed by Marilyn Thornhill, Tyler Galpin kills her, showing he is no longer under her control. It remains unclear if Tyler is now his own master or if someone else is secretly controlling him, as Hydes must always have a master. Tyler also attacks Wednesday, throwing her through a window, which leads to her going into a coma rather than dying.

Wednesday discovers that Agnes DeMille, a peer at Nevermore with invisibility powers, has been stalking her and sending messages, but Agnes is just a superfan trying to help solve the mystery. The real stalker is someone else using a deadly one-eyed crow to surveil Wednesday, indicating a more dangerous threat remains unknown.

Augustus Stonehurst was a 'normie' science teacher at Nevermore who later became head doctor at Willow Hill. He falsified death certificates and cremations of outcasts who were actually alive. After a psychotic break, he was admitted as a patient at Willow Hill, and his past and actions are central to the mystery Wednesday investigates.

Enid is revealed to be a rare 'Alpha' werewolf who can transform without the full moon. She is warned that transforming during a full moon could cause her to remain a wolf permanently and become prey to other werewolves. After helping save Wednesday from being buried alive, Enid sacrifices herself by transforming permanently and runs off into the woods.

Isaac Night, disguised as Slurp the zombie, is the mad genius behind outcast-reversal technology stolen by Augustus Stonehurst. He plans to use this machine to free Franciose of her Hyde powers permanently, using Pugsley as a power source. This plot is central to the season 2 finale and sets up future conflicts.
