The season opens with a shocking cold open: a Supe named Webweaver (a hilarious Spider-Man parody) is graphically murdered. Butcher (Karl Urban), now terminally ill from Temp V, is barely holding his crew together. The episode establishes the central McGuffin: a virus that kills only Supes, created by a mysterious scientist. Meanwhile, Victoria Neuman (Claudia Doumit) tightens her political grip, and Homelander (Antony Starr) deals with the fallout of his public trial.
The entity, dubbed “The Butcher,” is a literal demon that speaks to Butcher, representing his id. It kills a room full of guards while Butcher watches in horror. Episode 5: “Beware the Jabberwock, My Son” Logline: Ryan chooses a side. A-Train’s heart grows three sizes. The Boys fracture.
The finale is pure chaos. Homelander, now acting president, orders a Supe purge of all “non-compliant” humans. The Boys, reunited out of desperation, plan to release the Supe-killing virus into the White House’s air supply. But Ryan, now fully radicalized, blocks their path. The climax sees Butcher confront Ryan—not to kill him, but to warn him. In a shocking twist, Butcher turns the virus on himself, unleashing his tentacles to destroy the entire building.

In an episode that rivals “Herogasm” for sheer depravity, the team infiltrates a secretive Supe orgy to retrieve a vial of the virus. The visuals are NSFL (Not Safe For Life). Frenchie, still haunted by his past as an arms dealer, confesses to killing Kimiko’s brother years ago—a betrayal that shatters her trust. Meanwhile, Neuman’s daughter Zoe is accidentally infected with the virus, forcing Neuman to make a desperate alliance with Homelander.
This episode is a masterclass in satire, targeting influencer culture and wellness cults. Frenchie (Tomer Capone) infiltrates a compound run by a hippie Supe named Tilda, only to discover she’s harvesting organs. Meanwhile, Homelander takes his son Ryan (Cameron Crovetti) to a remote cabin to “train” him—which translates to psychological torture. The episode ends with Ryan accidentally killing a protester, solidifying his dark turn.
