Re:ZERO season 4, episode 9 deepens the mystery around the slaughter at Priestella while pushing Subaru into one of his most helpless and unsettling situations yet. Where early seasons used Subaru as our clear-eyed proxy to discover the new world, this arc flips that dynamic: viewers now know considerably more about the stakes, the players, and the dark mechanics at work. That knowledge makes Subaru’s missteps and assumptions all the more painful to watch — and it raises difficult questions about who is operating behind the scenes and what “Return by Death” truly invites into his life.

Subaru as the Audience Proxy — When the Tables Turn
In earlier seasons, Subaru functioned as our primary lens: every new rule, monster, and social custom was learned through his confusion and energy. By now, viewers possess a map of the world that Subaru no longer has. That discrepancy creates dramatic irony — we can see motives, timelines, and likely culprits far more clearly than he can. Episode 9 exploits that gap to build tension: while Subaru scrambles to identify who killed him and whom to trust, we can already eliminate or prioritize suspects based on motive, means, and opportunity.
Suspects and Red Herrings: Who Could Have Killed Subaru?
Sorting the realistic possibilities
From the evidence presented so far, only a handful of characters realistically fit as Subaru’s killer in the massacre timeline: Meili, Shaula, Rem (or someone in Rem’s body), or an unknown third party. Meili checks motive and opportunity in some scenarios — she has reasons to target certain individuals — but the timeline often rules her out for the specific push into the pit. Shaula is an obvious threat when violence spreads through the tower after rules are broken or when chaos erupts. But the most intriguing angle is the third party: a figure who appears to toy with Subaru and even calls him “hero,” which implies knowledge of his public acts and possibly of Return by Death itself.
The red herring of “Rem”
The scene that looks like Rem killing Subaru is intentionally deceptive. The voice and behavior don’t quite match, and the killer’s familiarity with Subaru’s title hints that this Rem-like figure may be an impostor or someone controlling Rem’s body. That opens the door to Archbishops of Sin, shapeshifters, or other memory-consuming entities who could manipulate appearances and knowledge. Given the series’ established supernatural loopholes, it’s reasonable to suspect shape-change or memory-eating as part of the murder strategy.
Three Forces at Play in the Massacre
Episode 9 implies a layered attack rather than a single culprit. A plausible breakdown:
- Meili attempts targeted revenge but misses key opportunities in the chaos.
- Shaula or another violent actor escalates the carnage after rules are breached or when Subaru leaves the designated area.
- A controlling third party — likely the most cunning — eliminates those who survive the first waves and orchestrates Subaru’s final death, even mocking him with knowledge of his title.
These overlapping threats create an atmosphere of unpredictability and highlight how vulnerable the group becomes when multiple agendas collide.
The “Hero” Clue and Return by Death Implications
The killer’s use of the word “hero” is more than theatrical cruelty — it suggests the murderer was present when Subaru’s reputation was cemented, or at least aware of his public persona. That awareness strongly implies an entity attuned to Subaru’s personal history, which could mean the killer consumed his memories or observed him in some hidden way. If so, the murderer is not just physically dangerous but metaphysically connected to Subaru’s power: they may understand Return by Death and possibly exploit it.
Subaru’s Psychological Spiral: Starting from Zero — or Worse?
Season one’s theme — tear down Subaru’s ego so he can rebuild realistically — was straightforward. He faced tangible antagonists and could slowly learn from each death. This season offers something more insidious: the sense that Subaru might be fundamentally powerless in this setting. He’s confronted by incomprehensible magic, unseen attackers, and victims who die in ways that don’t clearly loop back to him. Unlike earlier arcs where his mistakes could be corrected through repeated attempts, the present threats are so alien that repeated deaths may not yield usable knowledge. The danger is not only physical but existential: if Subaru concludes he can’t help or contribute anything, he may withdraw instead of acting, which would cost the team irreplaceable advantages.
Character Growth: Humility vs. Helplessness
Subaru’s previous arc involved painful humility — recognizing his limits and learning to ask for help. That process made him effective in many later scenarios. Now, the show tests whether Subaru will rediscover agency in a far more hostile environment or whether the weight of repeated, senseless loss will depress him into passivity. This season could therefore pivot in two directions: a new arc of growth that redefines his role beyond past tropes, or a darker narrative examining the corrosive effects of powerlessness when even death does not yield reliable lessons.
Directorial and Thematic Highlights of Episode 9
Episode 9 excels in atmosphere and misdirection. The sequence through the miasma and the tower massacre are staged to maximize disorientation — both for Subaru and the audience. Small details, like the killer’s mocking final line or the timing of who is near the pit when Subaru falls, are deliberately ambiguous to encourage speculation. The episode balances visceral horror with plot clues, giving fans reasons to theorize while making Subaru’s suffering feel narratively consequential.
Where This Mystery Might Lead
Future episodes should clarify whether the killer is an Archbishop with shape-changing or memory-consuming abilities, or some entirely new force exploiting Return by Death. If the murderer truly understands Subaru’s ability, we may see traps engineered specifically to exploit the knowledge loop: memory theft, staged scenarios to manipulate timelines, or even alliances formed with beings who can bypass or exploit death resets. The stakes will remain psychological as well as physical, with Subaru’s inner resilience tested as sharply as his body.

Final thoughts
Episode 9 cements this arc as one of Re:ZERO’s most intellectually and emotionally fraught stretches. The show no longer simply throws challenges at Subaru to be overcome with trial and error; it pits him against enigmas that can’t be brute-forced with more deaths. That makes every failure more consequential and every apparent clue heavier with meaning. Whether Subaru emerges more capable or more broken will define the season’s emotional core — and keep viewers debating motives, timelines, and who truly pulled the strings in the tower massacre.
