Mercy for None Episode 4 Recap: Gi-jun’s Vengeful Rampage

Mercy for None Episode 4 brings the drama to a boiling point with raw vengeance, violent showdowns, and the chilling reminder that in this world, rules are written in blood. The episode opens with Chairman Bong-san meeting Yeong-do, instructing him to eliminate Gi-jun now that Ju-woon has been handled. Meanwhile, Jun-mo makes his own move—hiring champion-level fighter Jeong In-seok and offering one billion won to take Gi-jun down.

At Byung-ho’s office, Jun-mo confronts him with his new enforcers. Byung-ho warns Jun-mo not to pursue Gi-jun, but the warning is met with a baseball bat to the skull. Chun-seok arrives moments too late, only to suffer the same fate. Jun-mo answers Gi-jun’s call to coldly announce their deaths and taunt him with the safe house address.

Gi-jun, bloodied but unbroken, finds Byung-ho’s body and retrieves a new bat left behind for him. As vengeance brews, Chairman Bong-san escalates his own play—having Detective Han kidnapped and interrogated over the orchestrated death of Gi-seok. A shocking audio recording reveals a voice from the past, hinting that Gi-seok’s death may have been part of a deeper conspiracy. Bong-san’s reaction suggests he knows exactly who’s behind it.

At the safe house, Jun-mo lures in a mob with promises of money for delivering Gi-jun alive. But when Gi-jun arrives, he wastes no time unleashing calculated fury. He mows down the thugs one by one, sending many fleeing. Only Jeong In-seok stands firm, demanding double pay to finish the job. The fight is grueling. In-seok initially dominates, but Gi-jun gains the upper hand by stabbing him in the eye with a shard of glass and finally beating him unconscious.

Jun-mo, desperate and weaponless, begs for mercy. But Gi-jun has none left to give. One final swing of the bat ends it. He calls Bong-san and confirms Jun-mo’s death, asserting he acted according to the rule—an eye for an eye.

The episode ends on a grim note. As Gi-jun drives away, a mysterious car ambushes him and forces him off a bridge into the river. A man with a hand tattoo reports back that Gi-jun is dead—hinting at yet another layer to the conspiracy.

Mercy for None Episode 4 recap reveals a world that’s only getting darker, more ruthless, and impossibly tangled in betrayal and revenge.
