Mercy for None is not holding back. Just when I thought things couldn’t get any more intense, episodes 3 and 4 come crashing in like a bat to the face — literally. The pace is faster, the fights more brutal, and the secret even messier . And the centre of it all? Gi-jun, our one-man army, is on a rampage that somehow keeps getting more personal. If you haven’t started this drama yet, what are you even waiting for?

Mercy for None Episode 3 kicks off with Chairman Bong-san trying to put a hit on Gi-jun. But even the assassin he approaches flat-out refuses. That’s how terrifying Gi-jun’s reputation is. While Bong-san moves Jun-mo to a safe house, Jun-mo throws a full tantrum because he doesn’t get what all the fuss is about. But the tension hits the ceiling when Gi-jun storms into the De ‘cro hotel in full beast mode. Chun-seok barely escapes with Jun-mo, while Dong-kyung is left to hold off Gi-jun.

Elsewhere, Sim Seong-won is caught trying to run, and Gi-jun gives him 24 hours to spill Jun-mo’s location. Meanwhile, Seon-cheol figures that his son Geum-son has been spying on him . Geum-son, in true chaos-agent fashion, suggests that they take down Bongson together
In the safe house, Chun-seok finally spills the tea on Gi-jun’s past in a major flashback. Turns out,11 years ago, Gi-jun helped Ju-woon and Bong-san rise to power during a brutal gang war. He even killed the former chairman’s son, Seung–won—well, that’s what everyone thought.
Mercy for None Episode 3 Review: Choo Young Woo
Gi-jun basically handed them the empire, but as punishment for the bloodshed, they cut his Achilles tendon and exiled him.Brutal.In the present, Jun-mo hires foreign assassins to kill Gi-jun (bad idea ). Chun-seok, tricked by Jun-mo, sends Gi-jun into a trap. But of course, Gi-jun turns it around, kills the assassins, and calls Jun-mo “we ‘re not done”. The episode ends with a game -changer –Gi -Gi-Gi-Gi-seok, not Gi-jun, killing the chairman’s son. That changes everything.

His real challenge comes when he faces Jeong In-seok. The fight is rough –Gi-jun takes hits , bleeds , and nearly collapses . But then he grabs a glass shard, stabs In-seok in the eye, and finishes the job. Jun-mo tries to pull a gun, but Gi-jun’s too fast. One swing of the bat –and it’s over.

Flashback: Gi-seok once told him they should meet more often. A memory that hits hard.Then BOOM –a car rams Gi-jun’s.It plunges off a bridge. A man with a hand tattoo watches the car sink, makes a call, and says, “He ‘s dead”. Please. We all know he’s not.
Mercy for None Review
These episodes take mercy for None to another level. We‘re no longer just watching a gang war –We’re watching a man unravel and unleash hell.Gi-jun is a machine, but not just in how he fights. It’s how he carries this quiet sadness, this guilt. So Ji-sub nails that emotional weight while still being a total badass. And the fight scenes? Flawless. Especially one-on-one with In-seok. Raw, ugly, intense. No flashy martial arts, just brute survival.
Mercy for None Episode 3 Review: So Ji Sub
As for Jun-mo, his transformation into a full-blown villain is disturbing but kind of fascinating. He’s terrified, desperate, and evil all at once. That bat scene still haunts me.I wish we had a more emotional payoff with Byung-ho’s death. It felt rushed. I also want more clarity on Yeong-do and his motives. But even with those small gaps, the storytelling is gripping and lean. The visuals—those neon shadows and grim palettes – still hit hard. And the music? That eerie background score adds so much tension.
Final Thoughts
Mercy for None Episode 3 and 4 are easily the strongest so far. The emotional weight, the action, the pacing — it’s all razor-sharp. Mercy for None isn’t just another revenge drama. It’s a violent symphony of betrayal, loyalty, and survival. And I’m all in.
Gi-jun’s journey is far from over. That bridge crash may slow him down, but come on—he’s not going out like that. There’s still more to uncover, and if you’re into dark, gritty K-dramas with morally grey characters and high–octane tension, this one’s absolutely worth your time. Go catch up. You won’t regret it.
