Re:ZERO Season 4 Episode 3, titled The Keeper of the Watchtower, is the point where Season 4 stops warming up and properly starts hurting.
For Malaysian and SEA anime fans following the weekly discussion, this is the kind of episode that makes the group chat go quiet for a second before everyone starts typing in all caps. Arc 6 has a reputation among Re:ZERO readers, and Episode 3 finally gives anime-only viewers a clearer taste of why people kept warning them: the watchtower is not just another destination. It is a trap with rules Subaru does not understand yet.
The setup is small, which makes it nastier. Subaru wakes up after being separated from the rest of the party, with Ram explaining what happened. We learn Subaru caught Ram during the fall, leaving them together underground. Anastasia and Patrasche are also there, and yes, Subaru is understandably relieved to still have his loyal earth dragon nearby.
But Re:ZERO being Re:ZERO, comfort never lasts long.
What makes this episode work is how quickly the atmosphere turns poisonous. The group is walking through a dark, strange route, but the danger is not only physical. The miasma starts messing with people, and suddenly trust becomes fragile. Subaru and Ram’s dynamic is usually sharp, familiar, and fun to watch, but here it gets twisted into something genuinely unsettling.
The blue-lit tunnel sequence is the standout. WHITE FOX lets the scene breathe instead of throwing loud horror music everywhere. The cold lighting, tired faces, and awkward pauses make everything feel wrong before the violence even hits. Subaru turning on Ram is disturbing not because it is flashy, but because it attacks one of the emotional anchors of the party. Anastasia, or Foxidna, reacting with confusion only adds to the feeling that nobody in the scene fully understands what is happening.
Ram also becomes the episode’s low-key MVP. Even under the effects of the situation, she still manages to save Subaru. Later, she does it again during the clash with the mysterious mabeast, and this time she appears to survive the encounter too. For a character who often acts like she has zero patience for Subaru’s nonsense, Ram stepping up twice lands hard.
Then there is Patrasche. Bro, that sequence is rough. Re:ZERO has never been shy about showing Subaru getting destroyed by terrible choices and impossible odds, but Episode 3 pushes the brutality in a way that feels especially personal. The mabeast fight has that underleveled RPG boss energy — Subaru is not prepared, the enemy is too much, and Return by Death starts feeling less like a power and more like a punishment.
That is the big shift this episode delivers. The watchtower no longer feels like the goal after a long journey. It feels like a place already eating the party alive before they even get a proper welcome. For SEA viewers who enjoy Re:ZERO for its psychological pain as much as its fantasy lore, this is exactly the kind of episode that reminds you why the series still hits different.
Episode 3 also debuts the ending video, while the story continues to build curiosity around Shaula and what role she will play inside the watchtower. If this is only the opening bite of Arc 6’s suffering, Season 4 is about to become seriously stressful viewing.
