Ep. 54: Mustang refrains from killing Envy after Edward explains the homunculus's jealousy of human resilience.

Hawkeye shoots the disguised Envy until the real Mustang arrives to incinerate him, reverting him to a parasitic state. Edward, Hawkeye, and Scar persuade Mustang to abandon his revenge, arguing that Amestris cannot be ruled by hatred. Envy rants about human cruelty, but Edward deduces that Envy’s hatred stems from jealousy over human resilience. Humiliated by this understanding, Envy destroys his own philosopher's stone and commits suicide. Meanwhile, the Armstrong siblings gain the upper hand against Sloth. Izumi arrives in Central with Briggs Fortress soldiers to join the coup d'état. Elsewhere, Hohenheim confronts Father alone. This sequence highlights the shift from vengeance to understanding, as Envy’s self-destruction contrasts with the ongoing battles and political movements shaping the fate of the nation.
