Season 2’s finale pivots on a late-game unmasking: the shambling zombie “Slurp” isn’t just a random monster-of-the-week. He’s Isaac Night—and his return cracks open a buried Addams family secret that redefines what viewers think they know about Gomez, Morticia, and even Thing.
Who Isaac Night Really Is
Isaac Night is revealed to be a former Nevermore-era outcast and brilliant inventor, tied directly to the Galpin/Night family line. Netflix’s official character guide explains that “Slurp” was hiding a dangerous secret: he’s actually Isaac Night, connected to Francoise and Tyler’s story.
Over the season, the show tracks Isaac’s “upgrade” from undead comic horror into a calculating opponent—using his intellect and obsession to drive the finale’s central threat.
The Big Reveal: Thing’s Origin Is Tied to Isaac
The finale drops the wildest twist: Thing is Isaac Night’s severed right hand.
According to Netflix’s Tudum ending breakdown, Morticia cut off Isaac’s hand years earlier, and it later reanimated and became Thing—complete with a cheeky on-screen confirmation that “Thing” is an anagram of “Night.”
That’s not just trivia. It reframes Thing as more than a loyal Addams companion; he’s literally a relic of a violent incident the Addams family has been sitting on for decades.
What Isaac Reveals About the Addams’ Dark Past
The season’s final episodes establish that Isaac’s history with the Addams family goes way back—specifically to Gomez and Morticia’s younger years.
Entertainment Weekly’s recap describes a flashback where Isaac recruits a young Gomez to help power Isaac’s machine using Gomez’s electrokinesis, but hides the real cost of the experiment—then Morticia intervenes, severing Isaac’s hand and derailing the plan.
The malfunction costs Isaac his life, and Gomez loses his electrokinesis powers. Afterwards, Gomez and Morticia conceal Isaac’s body, keeping the whole event buried along with it.
In other words, the Addams’ “dark past” isn’t just gothic vibes. It’s a concrete, violent cover-up with lasting consequences—one that literally created Thing and shaped Gomez’s abilities.
What Isaac Is Doing in the Finale
In the present-day storyline, Isaac takes Pugsley and drags everyone toward his “Hyde” plotline—centered on a machine designed to remove Hyde traits, with Pugsley as a power source.
Multiple reputable recaps converge on the same outcome: Isaac’s plan spirals into chaos, and the Galpin/Night family conflict turns lethal.
How Isaac Is Defeated
Isaac’s downfall is poetic: Thing turns on him.
TVLine and Netflix Tudum both describe the climactic beat where Thing regains autonomy and removes Isaac’s mechanical/clockwork heart, ending him (again).
This matters thematically: the Addams family’s oldest secret isn’t solved by a courtroom confession or a clean victory. It’s solved by the living evidence of that secret—Thing—choosing the Addams over Isaac.
What the Finale Sets Up for Season 3
The ending doesn’t just wrap Isaac’s arc; it tees up several new ones:
-
Enid’s disappearance/rescue mission, with Wednesday heading out alongside Uncle Fester.
-
Aunt Ophelia’s looming threat, punctuated by the ominous message “Wednesday must die.”
-
Tyler’s next chapter, pulled toward a larger Hyde collective.
-
Fallout at Nevermore, which the finale treats as unstable and politically combustible.
