The Boys Season 5 Episode 4: King of Hell

Homelander's apotheosis deepens: he orders Firecracker to shape his image into that of a god. The Boys, still hunting V1, make for Fort Harmony.

Inside the fort, Frenchie discovers an airborne strain of toxoplasmosis that fills everyone but himself with intense hostility. When the group learns that Bombsight has stolen all the V1 vials, that hostility erupts — and they turn on each other.

Homelander and Soldier Boy arrive at Fort Harmony in search of V1 and fall into a fierce argument, which ends with Soldier Boy trapping Homelander in a room filled with concentrated uranium.

Frenchie tracks the toxoplasmosis to its source: a mutated human. Soldier Boy identifies him as Quinn — and, enraged by Frenchie, kills Quinn, restoring the others to normal. Freed from the uranium room, Homelander moves to attack Soldier Boy but stops when he sees him grief-stricken.

Away from the fort, Annie reconciles with her father and reunites with Hughie. Oh Father publicly announces the Democratic Church of America, proclaiming Homelander “the Lord’s prophet.”

The ending stacks three turns. Soldier Boy kills Quinn — the mutated source of the airborne toxoplasmosis — in rage at Frenchie, restoring the infected to normal. Homelander escapes the uranium room and moves against Soldier Boy, but stops short at the sight of his grief.

The larger ending belongs to the country: Oh Father announces the Democratic Church of America and proclaims Homelander “the Lord’s prophet,” while Annie quietly rebuilds her life — reconciling with her father and reuniting with Hughie.
