I was late to posting Ep. 78 and given it didn’t actually have all that much to talk about, I decided to do a write-up on both Eps. 78 and 79 instead since I believe they’re better off written as a package. Combined, the two episodes have so many callbacks, which was a joy to watch and think about for me.
Ep. 78 opens with amnesiac Subaru looping and greeting Emilia right away as her having done so much for him in the loops after he had come into being coupled with her confession to him made him legit fall in love with her all over again. And of course since Beatrice was the one that did the most to protect him from physical harm in Ep. 77, he was of course crying over her for ever having doubted Beatrice in the first place given in Ep. 75 the ones he had suspected most were Emilia and Beatrice since he never found their bodies, which is impossible in the case for Beatrice since she dissipates into mana upon dying, and for Beatrice’s sacrifice to save him in Ep. 77 from the discarded piece of the scorpion mabeast (that was probably Shaula after she slowly became it in both mind and body as shown by how she went from standing upright to falling towards a more inhuman posture that was meant for viewers to fill in the gap later after watching Ep. 77) left behind that exploded as a defense mechanism to kill those who pursue her, and probably as a release for all of the suffering he’d gone through.
We then see much of the same happenings as before with Julius being disturbed of amnesiac Subaru having no memories of the previous night, probably ’cause Julius intended to mend their relationship the next day, which he could no longer do since Subaru doesn’t know what exactly happened between them that led to that rift, Meili thinking amnesiac Subaru is so much trouble, and Ram distressed ’cause she had believed strongly in Subaru being the one who’d save Rem, and amnesiac Subaru explained it away as having no episodic memories, meaning he retains knowledge of their names and how he’s connected to them and who he is but can’t remember the specifics of anything involved, which is a legitimate expression of how someone with no episodic memories can experience life.

After amnesiac Subaru revealed to Ram in private that he’d genuinely lost his memories and forgotten Rem, she was of course distraught since she believed he was the one person she believed would never forget about Rem even if everybody was destined to, showing her belief in how Subaru was Rem’s anchor to the world given her state of suspended animation and also how he was Ram’s anchor to her sister as Ram would have no idea that Rem was her sister if Subaru had not insisted on finding Rem among the pile of bodies after Regulus and Lye had attacked the camp heading back to Lugunica’s capital.
Given Ram had forgotten about Rem’s contributions to Arc 2 due to Lye’s Authority of Gluttony, she of course held Subaru in even higher regard than she otherwise would have, and Roswaal having been revealed to no longer allow Ram to bring him his underwear after having learned that Ram genuinely loves him in a Season 3 Break Time episode ultimately has resulted in Ram being in a state of much, much higher stress than normal given Roswaal isn’t here to restore her mana like he usually does and since she loves his presence in general, but she was able to push past that.
I can see why people are upset that Ram slapped amnesiac Subaru, but she had the grace to show him she believes the true him will return even after she took roasted him in saying he was bad at keeping promises, and it just shows Ram and Subaru had built a genuine friendship in this last year he’s been in the fantasy world. Yeah, Ram’s very prickly to most people, and I’m not excusing that, but she genuinely does have belief in Subaru as shown by Eps. 40 and 78, and I enjoy how far they’ve come. This isn’t to say some people can’t get triggered by this dynamic though as what would be seen as a sibling dynamic for some could be seen as a dynamic of abuse by others who had negative experiences in which they were gaslighted by a manipulative person.
Subaru then sets a trap/intervention for Meili ’cause he had realized from the height of the person who pushed him and Meili’s tendency to resort to killing to resolve her issues since she never learned how to deal with her emotions due to her upbringing as a feral child, as Elsa’s apprentice, and as Capella’s underling, and since Subaru believes in the innate goodness of children much like Jean-Jacques Rousseau and Hans Christian Andersen as shown by how Subaru indicated in Season 2 that he doesn’t want to kill kids, he took it upon himself and for the entire group to raise Meili and give her a good example to live by that would be different than the example Elsa taught her.
I mention Jean-Jacques Rousseau and Hans Christian Andersen ’cause I’m also covering Sayonara Lara this season, and those two were both religious, and Re:Zero itself draws quite a bit from Christianity in believing in redemption for others, much like how the group forgave Roswaal after all he’d done in Season 2 and even in Season 1 with him having revealed himself in Season 2 to have hired Elsa to get Emilia’s insignia in Arc 1, which was centered around the loothouse, and also having allowed the Witch Cult to run rampant in Arc 3 (Eps. 12-25), by not intervening, which posed huge problems for everyone involved, and it also draws from Christianity in how Witches, warlocks, and Sin Archbishops of the Witch Cult are based on sins. Subaru also has at many points forgiven those who have wronged him, while part of it is ’cause he has a fear of abandonment, I believe part of it is ’cause Tappei also deliberately intended for his story to take the stance of God having unlimited grace for humans through Jesus Christ, covering all past and future shortcomings.
The end of Ep. 78 and the start of Ep. 79 have amnesiac Subaru talking about putting his memory loss aside ’cause something in the Pleiades Watchtower caused him to lose his memories, so facing the exams head-on will result in them uncovering the reason for his memory loss, and the group agrees that Reid Astrea’s Book of the Dead almost certainly exists since Reid isn’t the type of guy to stick around too long in one place from what they’ve seen of him based on his lively personality, he shouldn’t belong to that of an extremely long-lived species, and since the Astrea family probably consists of humans, the same should apply to him especially since it was stated in Ep. 70 that he’d died of old age even if a lot of info from four hundred years ago is questionable.
As they were headed to the archive, Subaru decided to have he and Julius stay put as Julius’s body language was negative, and Julius begrudgingly admitted that they they have no other alternatives and that Subaru’s plan is the best one, and Julius’s behaviour born from Julius’s inferiority complex to Reinhard from childhood when Reinhard easily defeated Julius’s swordplay instructor, leading to him having doubts about his own ability up to this current day, as shown by Ep. 72 with the flashback to that, and how Julius took great pride stepping into Reinhard’s role as the sword of the kingdom to defeat Petelgeuse Romanee-Conti in combat in Ep. 24, and Julius’s name having been eaten, resulting in most people in the world forgetting him is really triggering this insecurity, especially since he had a strong belief that the most capable fighters are also those with the best character, only for Reid to run afoul of that AND beat him down twice. Thus, amnesiac Subaru having no memories of that past and his humiliation at the hands of Reid allowed for Julius to regain some of his mojo since even this version of Subaru thinks highly of him just ’cause of his appearance when he had no other person in this world who remembered what he could do on the battlefield at his peak, with Subaru saying of, “That’s one thing, and this is another.” being very impactful for him ’cause amnesiac Subaru was basically telling him to forget whatever happened the other night and not to sweat it, leading to him deciding to treat his previous losses as a throwaway, throwing that same line back at amnesiac Subaru, which is excellent character writing and a good way to alleviate some of Julius’s current issues, and to top it all off, it’s something only this current version of Subaru could’ve done, and there’s a point to this as shown by later in this episode.
In the Great Pleiades Library itself, Beatrice and Emilia both show care for amnesiac Subaru after he declares his intent to read Reid Astrea’s Book of the Dead due to them having found him unconscious in the archive without his memories, and even Ram had shown concern before that by saying none of them have read it due to being concerned about potential memory loss when he asked a leading question. Before that, he also made it clear he intends to find Elsa’s Book of the Dead as he’d cut no corners in ensuring Meili grows up healthy in not just her body but also her mind given the strong connection she felt to Elsa after it was revealed that Meili had found the relevant book. Subaru got everyone to agree to him reading Reid’s Book of the Dead by playfully designating everyone a role, including calling Julius the fighter to lessen the blow to his currently wounded ego, designating himself to be the reader of any Books of the Dead.
However, instead of peering through Reid Astrea’s memories, amnesiac Subaru instead found himself in the Corridor of Memories with Rui, who tells him that it’s the cradle of Od Lagna (Crunchyroll screwed up the translation here with the comma after cradle since it turned the sentence into gibberish), making it sound like Od Lagna and the Corridor of Memories are the exact same thing. As for why Reid’s Book of the Dead led to the Corridor of Memories, I suspect it’s ’cause Echidna’s the one who made the Books of the Dead and can decide who can read them based on my previous speculation. Meili’s Book of the Dead appearing to this group of people so soon when the group had concluded initially that the books aren’t sorted by name or date of death in Ep. 71 suggests that there’s a will behind when and where Books of the Dead that can be read appear. This is backed by how in that relevant episode, both Subaru and Julius were able to find one they were able to read almost right away, suggesting a will or higher power is what allowed for that to happen.
We know from the anime there’s someone who has the power to see a perfect reconstruction of the past, and that’s Echidna with her Authority of Greed: Tome of Wisdom, and if my speculation about Roswaal’s not-quite-Tome of Wisdom and the Witch Cult Gospels are correct, they may be made with pieces of Echidna’s hair, fingernails, toenails, eyelashes, eyebrows, other facial hair, dead skin, zits, dandruff, body hair, and/or her body fluids such as her saliva, sweat, and the enzymes from other fluids, meaning they are connected to Echidna’s mind through magic, and that’s why Otto didn’t appear in Roswaal’s not-quite-Tome of Wisdom, and why Gospels don’t really tell the future, which is why Regulus thought that he’d see Emilia again in the first loop despite it not happening until the 4th loop in Ep. 53 with Regulus telling Subaru to thank him for adhering to his Gospel in not doing worse than shredding off a large chunk of his leg since he could’ve done much worse, and why Sirius indicated that they need to stop hostilities due to the toll of the tower, all of which very much went in Subaru’s favour, likely not by chance.
If Echidna decides what appears in the text of Roswaal’s not-quite-Tome of Wisdom, she can freely decide to omit Otto. That’s why I posit those texts are perhaps connected to Echidna’s mind through magic by being partially constructed with stuff from her body, possibly including her body fluids, meaning she 100% decides what shows up in them. Therefore, ’cause Echidna wanted Roswaal to lose and Subaru to win, Otto didn’t show up in his not-quite Tome of Wisdom. This is backed by Tea Party Echidna telling Subaru that even after 3 days of trial and error that she has no hope of breaking Emilia out of her shell, and maybe he could give the cowardly princess wings, showing she was telling him the way out of the situation was to do have Emilia do the Sanctuary trials. Tea Party Echidna also showed at that moment that she didn’t make the trials as hard as humanly possible but tried to coax Emilia out of her shell. Tea Party Echidna also said what was an evil as humanly possible regarding the reason she had Beatrice hole up in the Forbidden Library, knowing that it would push Subaru to take Beatrice’s hand instead of hers, and her saying that she doesn’t want Subaru to think that she’s the only evil one of the Witches of Sin, resulting in her taking away Subaru’s qualification for entering the tomb since he was using it as a crutch instead of supporting Emilia, was her doing good by Subaru in making sure he was victorious that loop.
Thus, archive’s filing system may be constructed in part from Echidna’s Authority and also magic from herself and possibly others such as Flügel, meaning she can possibly choose which books appear to certain people at any given opportunity based on future knowledge, which is how someone finds a Book of the Dead he/she can read at the lowest floor of the library so as to make it convenient.
Given Echidna’s Authority of Greed: Tome of Wisdom can show all of the past, present, and possible futures, and the Corridor of Memories is the Cradle of Od Lagna (Crunchyroll probably messed up the translation since Japanese doesn’t different from ‘l’ and ‘r’ since “Lagna” in Vedic astrology is the exact zodiac sign rising on the eastern horizon at the exact time and place of a person’s birth), which filters the souls of the dead and cleanses their memories so that they can be used again, making the Corridor of Memories the support system/cradle for Od Lagna, which probably shows that Od Lagna is actually the world’s memories whereas the Corridor of Memories is where the inaccessible memories are, such as the memories of someone whose names and memories had been eaten by Gluttony and the souls of the newly deceased. So it would make perfect sense if Echidna’s Authority drew its power from Od Lagna, and henceforth explains why Reid’s Book of the Dead connects to the Corridor of Memories since when a soul is ready to be reused again, it is ready for rebirth, thus Echidna’s Authority must capture the rebirth of anyone who’s ever lived, and that likely explains why amnesiac Subaru ended up at the Corridor of Memories.
Rui then reveals her background to amnesiac Subaru, and of course, he has no idea what many of the terms she talked about are, not realizing she’s an enemy, and during that conversation, he realizes that she keeps using the ‘we’ pronoun, which she explains as her having too many egos all in once place, so it’s not clear who’s in charge, and her saying all these egos are a gift from her two brothers suggests that Lye Batenkaitos and Roy Alphard are feeding to Rui some or all of their victims, possibly implying that they are all as one even if they are three entities and that Rui can somehow contain all these egos for whatever reason.
Rui then gives amnesiac Subaru a scare in showing they know about his past on Earth, which I’m assuming is ’cause his memories from Earth aren’t from this fantasy world, so they don’t stay eaten even though Rui and possibly the others can still remember them due to their recollection of his memories after consuming them, and this greatly unsettles him, causing him to push Rui down as she continues to use mind games on him, and she self-harmed by digging into her own skin, possibly ’cause of it being a habit she picked up from Subaru given Beatrice indicated he had a habit of getting scratches on himself as shown by Ep. 75, which I believe I didn’t pick up on at the time, and this interaction finally results in him realizing that Rui was the one who had eaten his memories.
Then it cuts back to those in the archive, and Shaula mentions that threats to the Pleaides Watchtower are approaching, telling them to protect her master, and Julius follows her while Ram and Emilia go get Rem. An enormous number of mabeasts were making a beeline to the tower, and Shaula used her Infinite Hell’s Snipe to snipe many of them, but that still wasn’t enough to stop them from breeching it. Ram and Emilia then see Lye Batenkaitos emerge out of the green room, and I’ll get back to this later.
As for why the mabeasts are storming the tower, I can think of three reasons:
1) Given that Lye and Roy are Sin Archbishops of Gluttony and that mabeasts had been created by the Authority of Gluttony, they have direct control over mabeasts.
2) Given Lye and Roy are supposedly both at the tower alongside Subaru, who all emit a ton of miasma, and since Subaru is currently connected to the Corridor of Memories, the miasma of all of Subaru, Rui, Lye, and Roy are at the Pleiades Watchtower, and mabeasts are drawn to large sources of miasma, which is why they are all gunning for the tower.
3) Since Subaru talked about returning and that this is the fifth version of him since Rui had eaten the original Subaru before he returned to the Corridor of Memories, Subaru’s amount of miasma is way high compared to normal, much like when he goaded the White Whale into pursuing him harder in Ep. 21 by talking about how he had suffered in the past, implying he can Return by Death, which is directly part of the Taboo as intentionally hinting about Return by Death is disallowed according to Subaru’s contract.
It’s probably some combination of all of these reasons for why this is happening.
Cutting back to Rui and amnesiac Subaru, she calls it amazing that he was able to come back to the Corridor of Memories once again and then asks him how many versions of him have come and gone since he had last been here (Crunchyroll screwed up the translation in rendering it as how many times had he died) with him replying five times to denote that he’d died four times with this current iteration being the fifth version of him since having his memories be eaten. She then says that she wants to eat him until her stomach bursts, pushing him down, saying that she believes she loves him as she considers appetite and lust to be similar before licking him provocatively to creep him out and make him consider killing her despite his belief that children should be forgiven ’cause they don’t know better.
Rui then continues her mind games against him, asking him if he really could wring the neck of a frail little girl such as her, suggesting he’s not capable of such a thing to basically dare him into doing it before attempting to mislead him in suggesting that if the original Natsuki Subaru came back that his current self would die since the old memories would erase this draft version of him, which is akin to dying. She asks him whether Natsuki Subaru really was worth all of that given memories are what shape a person, this current version of him and the relationships he has built (such as the current relationships with Julius and Meili). She then goes hard in attempting to sour amnesiac Subaru on the original Natsuki Subaru with false reasons for why he had relationships with Emilia (Crunchyroll may have screwed up the translation in saying Emilia had the same birth as Satella. Muse Asia said that it was ’cause of her looking like Satella, but I’m not 100% sure this is correct either given how incredibly different the translation are. I’m going to need someone who knows Japanese to clarify this later), Beatrice, and Rem, calling him drunk on playing the role of the saviour. Rui then goads him into killing her once again, directly placing his hand on her neck, and he starts sobbing about how he wants more time with everybody, implying he’s seriously considering killing the original Subaru now.
Then we get an update of events at the tower with Shaula still diligently spamming her needles, Julius tiring as he tries to prevent more mabeasts from advancing, and Ram having gotten Patrasche to carry her and Rem out of the green room while Emilia was fighting by herself against Lye, and given Lye had come out of the green room without hurting Rem and Patrasche before, this strongly implies as I’ve stated for over five years that Witch Cult Gospels don’t tell the future but are meant to guide the world to a specific future that develops Subaru and other characters in specific ways as an intervention against the world once again being destroyed by the Witch of Envy due to the character flaws of the Hero of the story with Echidna being highly likely to be the one controlling what appears in them as Rem being saved seems to be part of the grand plan.
Back to amnesiac Subaru and Rem, Rui goads him to declare that Natsuki Subaru’s nothing more than the stranger closest to him and to kill him so that he’s the one and only Natsuki Subaru. He then hears footsteps approaching him, and he thinks it’s the original Subaru coming to claim everything that’s his. And now comes a GIF to help explain everything about this scene:

In Ep. 37 (Season 2 Ep. 12) when Carmilla in the form of Rem was telling Subaru that he can rest and leave everything to her, Subaru protested, saying that the real Rem would tell him to stand up as she’s the one who wouldn’t let him shirk his responsibilities as someone who can’t give up halfway through something as her hero.
And now in Ep. 79 (Season 4 Ep. 13), when amnesiac Subaru was being led astray by Rui ’cause the Sin Archbishops of Gluttony wanted to lead him astray so that they could infinitely eat him by getting rid of the original Subaru’s memories through killing Rui, who had split herself into two exactly for the purpose of still being around after the Rui with Subaru’s memories was killed by amnesiac Subaru, Rem gave amnesiac Subaru the strength to be her hero once again.
That blue sphere Rui took out of her body was Rem’s existence/soul since having both your name and memories eaten is akin to your soul being eaten. Rem even as something that should’ve been immobile, used her force of will to give Subaru the strength he needed to prevail. It was a brilliant callback to that Season 2 moment and shows much planning Tappei put into the story.
This isn’t to say that Emilia didn’t also play a very nurturing role in Ep. 77 (Season 4 Ep. 11) and all the episodes she showed her care for amnesiac Subaru. She very much did, and her actions were what drove amnesiac Subaru decide to live up to the spirit of Natsuki Subaru, but amnesiac Subaru needed another push ’cause of Rui’s mindgame, which had seriously fucked him up and made him lose his resolve.
Subaru understood Rem so much in Ep. 37 ’cause Ep. 18 (From Zero) had Rem lay bare how she saw Subaru and how she felt about him ’cause of how he literally saved her repeatedly in the mansion arc by protecting her from danger and also allowing her to live for something other than being Ram’s replacement. I almost cried watching yesterday’s scene even though I’m not even a huge fan of Rem. I was choking up when I was talking about the scene as I watched. This is Re:Zero at its peak.
It’s surreal how amnesiac Subaru fell in love with both Emilia and Rem in a way that parallels how Subaru originally did in Season 1 with Emilia’s unlimited kindness for him, culminating in her giving him a lap pillow when he was struggling supremely due to his fear of abandonment in Ep. 8, and with Rem giving him the strength to not give up and see things through with Ep. 18, From Zero. Tappei loves writing parallels into the story, and it’s rewarding for big fans like myself to catch them.
And what’s more is that that scene foreshadows that Subaru awoke his Authority of Greed in that very moment, and I’ll use a GIF and an image comparison to help me explain this:


As you can see, the lights are meant to be a proximation of stars, and I highlighted in red the general shape of some stars with the one in amnesiac Subaru’s chest depicting the Regulus star, and given Regulus was the Sin Archbishop of Greed, it meant amnesiac Subaru awoke his Authority of Greed right at that moment ’cause of Rem urging him to stand up and save everyone to be as greedy as possible. As for the expression of the power, I believe Subaru can take in the emotions of someone else, who was in this case Rem, which allowed him to feel her overwhelming love for him, and that’s why Rem’s love took the form of a blue petal to depict that it was a part of her. I believe the entire confrontation with Rui is important since it legitimized amnesiac Subaru as his own distinct self, which is a big part of dissociation that many stories don’t get across right that another self is indeed a legitimate person in and of itself even as a part of a greater whole, and this is the reason Rui tried to make him feel completely distinct from the original Subaru so that he isn’t even considered the same guy so that after he killed her, the old Subaru would be lost forever, triggering her endlessly eating him even if it would never really actually satisfy her.
If you recall from my previous theory on Subaru’s Authorities, I believed that his Authorities are shaped by the biggest regret of each of those who reside in the dark world with Regulus’s biggest regret being that his first wife smiled in her final moments, showing her unhappiness with being his wife, and therefore, he desired to be able to share how he felt about her with her ’cause she never knew that he genuinely cared for her even though he slaughtered her family and the village the two lived in, meaning Subaru’s Authority of Greed might allow him to share what he feels with others. What I didn’t consider at the time since it was a rough draft of my theory is that communication is a two-way street, and Regulus wouldn’t have known to think to tell his first wife about his love for her had he not known about his first wife’s dissastisfaction with him, so Subaru’s power likely also manifested in being able to take what others feel inside their heart and feel it for himself, which is how he felt the warmth of Rem’s love she imparted to him to stop him from spiralling. All of this was due to Regulus deep down desiring connection with somebody, which he ultimately failed to do with his wife. For more on this theory and what I believe are the biggest regrets of the Sin Archbishops we know more about and how they impacted Subaru’s Authorities as I don’t want to rehash too much, read the relevant parts here: Re:Zero Episode 70 (Season 4 Episode) Analysis + Important Details – Thorough Watch
During that entire confrontation, Rui confirmed her plan to him, and very interestingly, she asks him about about life being unfair, how you can’t choose where you’re born, who your parents are, your environment, your future, or anything, and this is why she eats and eats and eats to search for the one rosy life that’ll make her life worth living. This makes me believe this is a hint to her biggest regret in life much like how Petelgeuse hinted in Ep. 15 that his biggest regret was killing the one he loved by his own hand, which he projected onto Subaru and Regulus’s biggest regret being what I said it was in Ep. 70. What’s relevant is that no matter how many memories Rui eats, she’ll never find one in which someone never experienced pain or suffering, so I think what she (and perhaps her brothers) are committing to a fruitless endeavor. So consequently, I believe Rui’s biggest regret is eating so many memories just to experience pain and suffering, that which she doesn’t enjoy, and if she could get a do over, she’d prefer to only eat a small piece of someone so that she could only eat a good part, such as someone’s shining moment, and that will have made her believe life was worth living instead of having that good part accompany negative memories/experiences, and how Subaru’s Authority of Gluttony could manifest with Rui’s biggest regret is that he only eats a piece of someone’s name or a piece of their memories, allowing him to perhaps eat the principal traumatizing event that caused great discomfort to somebody.
That portion about Rui about how you can’t choose anything is very particular. Given Rui only came into the physical world when she either swapped places or possessed Lye after he got hit by the powerful metia Felt and Beatrice had used, which knocked him unconscious, Rui may not have a physical body, and that’d mean she knows the Corridor of Memories filters souls and cleanses them of memories ’cause she has been there for the entirety of her existence with her soul somehow not having completed the cleansing process, leading to her not being born into the physical world. However, even if she strongly desires to live, as she had never been born in the first, assuming my theory is correct, I believe never being born wouldn’t count as a regret as being born or not is something you can only regret from a meta standpoint if you had actually been born, so I don’t consider that a legitimate expression for how Subaru’s Authority of Gluttony can manifest itself.
In any case, I now fully buy into Sirius Romanee-Conti’s comment about Petelgeuse’s soul having amalgamated with Subaru’s, and I believe Regulus’s has as well. If that’s the case, assuming my theory about Subaru’s Authorities being shaped by those in the dark world is true, one could look at it from the lens of Christianity and say that the Sin Archbishops would be getting their redemption through the expression of Subaru’s Authorities to be kinder versions of themselves that they couldn’t be in the past. I believe this would make for an excellent plot twist if I’m right about all of this.
All in all, I’m extremely satisfied with Ep. 79 and believe it was one of the best episodes of the season with excellent character writing, great subject matter, story beats, foreshadowing, as well as absolutely stupendous voice work from Rui’s seiyuu. Truly it is an example of the best of what Re:Zero has to offer, and I encourage any Re:Zero fan to sing its praises.
For the relevant Break Time shorts for Eps. 78 and 79 that delve more into Elsa and Meili’s relationship as well as provide more backstory for Sirius, here they are:
