· The Happiness Patrol Part 2

Ace and Wences evade Fifi with gasoline

Ace and Wences race through the labyrinthine pipes beneath the dystopian city, pursued by Fifi of the Happiness Patrol. Cornered at a dead end, Ace seizes desperation over despair, hurling a can of Nitro Nine into the creature’s path. The explosion erupts violently, engulfing the corridor in fire and smoke and blasting a jagged opening through the wall. The blast’s force thrusts them through the wreckage into unseen tunnels beyond, buying precious seconds against Fifi’s relentless hunting. The act is a bold inversion of Helen A’s oppressive control; they turn her weaponized surveillance back upon her regime, even as its fragility becomes visible in the aftermath. key_dialogue: [ ACE: Which way? Gordon Bennett. The Nitro, quick. The can! Keep down. ]
