There’s less to talk about regarding just this episode itself compared to Episode 67, but I still have some big things I want to emphasize here, so this will still be a long write-up since I’ll be highlighting how past content may apply heavily to the content of Season 4. The first of which is that names are very important in Re:Zero, which is why I have kept tabs on the names of Re:Zero characters since Episode 22 from Season 1, “A Flash Of Sloth”, since it could’ve referred to multiple things in the episode.
Based on Sin Archbishops having star names (Regulus’s name was a big plot point in Season 3) and Subaru revealing he was named after a star cluster in Memory Snow, it’s clear stellar names have significant importance in Re:Zero. Subaru is the Japanese term for “Pleiades”, a star cluster referred to as the Seven Sisters, the reason why the Seven Deadly Sins are a plot point, with six of the brightest stars in the Pleiades being visible to the naked eye under average conditions being why are there six dead Witches of Sin. Given Aldebaran means “follower of Pleiades”, this begs the question of why Al seemingly arrived in the world sooner than Subaru did given his name suggests he should’ve came after Subaru.
Thus, I theorize that Subaru was in suspended animation, the state Rem currently is in, within Flugel’s tree for hundreds of years, and that’s how Al seemingly arrived in the world sooner than Subaru did despite his name being follower of Pleiades, which should indicate that Subaru was summoned before Al was. This would be why I propose we see Flugel’s tree slowly grow from a sapling into a world tree before transitioning to the shot of Subaru since Subaru’s whereabouts were a mystery of sorts based on the connection between Al’s name and Subaru’s. And this is hardly a novel idea as other animanga have used the plot element of a person or multiple people being either in suspended animation or at least not aging inside a special tree.
Also of note is that in the OP, Subaru’s depicted as a hunk of flesh in clothes before his skin slowly surfaces when there were back-to-back shots of Echidna, Anastasia, Beatrice, and Subaru. This is very peculiar, and two things I can think of is that Subaru is either a homunculus or at least an artificial human, and both of the things I just mentioned merits raising the point about whether he was always a homunculus or artificial human or became one after being summoned, but now it’s time for a detour to remind readers of a previous theory of mine as my previous speculation actually supports Subaru being a homunculus or artificial human.
Al, Priscilla’s knight, in Season 3 also referred to Beatrice as Beako much like Subaru does, and I don’t believe that this means that Subaru and Al are the same person. However, I do believe that he and Subaru both originally came from the same soul. As I have said before, I have been researching the names of Re:Zero characters since Episode 22, and what’s very relevant is that Subaru’s dad is named Kenichi, which means ‘wise man’. Subaru said in Episode 16 that Flugel’s Tree was planted by a wise man centuries ago, and while this wouldn’t mean something in a different show, its presence in a show with Re:Zero’s long-term planning suggests that Kenichi himself might be Flugel. As for the time period in which Flugel existed, Petelgeuse apologized to Flugel-sama in Episode 43 for taking in the Sloth Witch Factor, which shows that Flugel was possibly from the same time period Satella was from since the sama honourific suggests Flugel was deeply respected by Petelgeuse. Liliana also knew of Flugel when she was in a travelling band with her parents, so it’s clear that whoever Flugel is he’s important to the lore of the series.
Episodes, 18, 25, and 38 show that Subaru has dormant memories of Satella as shown by how Puck indirectly revealed in Episode 18 the number of shadow hands Satella could generate to Subaru by asking Petelgeuse summon a thousand shadows if he truly wants to kill him, half of what Satella could (two thousand), how Subaru used a number associated with Satella (two thousand) to indicate his appreciation for Emilia in Episode 25 when he said that if Emilia named ten things she hated about herself he’d list two thousand things he loves about her, which Emilia herself commenting on why he chose that number, and how Subaru suddenly had an upwelling of positive emotion for Satella in Episode 38 that led him to say that he’d save Satella after she asked him to love himself and then some day come kill her, which shows that Subaru and Satella may have a past history together as lovers.
Given we know Echidna succeeded in creating a soul clone of herself with how Echidna spoke in her own voice in Ryuzu Shima’s body in Episode 49 and how Foxidna herself may also be a soul cone of Echidna’s, it wouldn’t be a surprise if Kenichi, if he is Flugel as I speculate, also did that as well, and Subaru and Al were both split off from Kenichi’s soul, and Kenichi made his sons his soul clones with that explaining why Al and Subaru both call Beatrice ‘Beako’, not ’cause they are the same person but because they were originally from the same soul. It’d also explain why Subaru has dormant memories of Satella despite it not being possible for him to have lived at that time, why Al also likes being rewarded for his efforts much like Subaru does, and why Al didn’t know about Capella’s powers, all of which shows that Al isn’t Subaru but that his origins are likely similar, and that something is up with Subaru and Al that doesn’t involve time travel or straight up reincarnation, so Al and Subaru may be homunculi or artificial humans who were split off from Kenichi’s soul.
I believe Subaru, and previously Al, is being put through the wringer to fulfill the grand plan I believe the heroes from four hundred years ago implemented, which included Satella, Echidna, and probably Flugel, to save the world from being stuck in a cycle of being destroyed by the Witch of Envy and reconstructed as hinted by Melakuera in the Frozen Bond OVA due to the actions of prototypical overpowered generic fantasy Heroes of the Story who encountered and lost to the Final Boss of the story every time due to the story path that began when an ancient hero in a moment of weakness of weakness, chose his lover over the world when the Seal in Elior Forest was opened, resulting in Re:Zero’s fantasy world being inevitably destroyed with the final boss of the time either activating an Authority or cursing the world to be extremely biased toward following the trend of that story path for all time with Satella destroying half the world perhaps being a deliberate intervention that was needed to allow the heroes of that era to deviate from the archetypal story path to pave way for Subaru.
As for how Kenichi could split his soul when he was the Hero of the story in Re:Zero’s fantasy world, I believe that would be impossible. Given Kenichi would have to follow the general story path I propose is happening, the Hero wouldn’t be allowed to split his soul while in Re:Zero’s fantasy world as the Hero of the story would be pushed to make it to the end to repeat the cycle, so dying by having his soul destroyed by an enemy or by himself, accidentally or intentionally, wouldn’t be allowed, so I propose that Kenichi at some point somehow returned to Earth to cut parts of his soul when he no longer had the designation as the Hero of the story, and eventually made Subaru and Aldebaran, who would eventually become his sons, Aldebaran after Subaru was whisked away. I think after all that I’ve finally explained why I believe Subaru being a homunculus or artificial human is line with my main theory.
As for the last part of the OP, it also has audio saying, “Let the magic stitch you back together”, when depicting Subaru’s sense of self seeming fraying with that out-of-character expression he had on his face and all the weird colours as he’s climbing stairs, so there may be something really stressful or traumatizing that causes some sort of identity crisis.
The first important detail is probably that Emilia still considers Subaru to be someone that needs to be protected, which is sort of a reversal of before in Arcs 1 and 2 when Subaru was doing all he could to protect Emilia regardless of whether she wanted him to, which is why she wanted Subaru stay behind in Arc 3 ’cause of his damaged gate, which eventually ended up being destroyed in Season 2 (Arc 4). Even after Arc 5 when Subaru and Emilia fought together against Regulus, Emilia still considers Subaru to be one of those who need protecting, much like Anastasia and Rem, to Subaru’s chagrin. Thus, since Emilia doesn’t consider Subaru an equal, I’m glad that they aren’t yet together especially since Subaru still has serious abandonment issues that flare up when Emilia doesn’t react to him well.
After that, the ground dragons react badly to Meili since those many years of handling mabeasts means she smells of them, which results in Patrasche and Joseph both picking on her with Joseph having Meili’s cape in his mouth. Julius settles things down by revealing that most ground dragons calm down if you stroke their necks. Roswaal then makes an entrance and tells Emilia and Subaru something offscreen that based on content from Seasons 1 and 2 implies that since Ram lost her horn she can’t replenish her mana, examples being after she expended a lot of mana in the mansion arc and after Roswaal nearly killed her in a fit of rage, both scenarios requiring for Roswaal to tend to her since as Beatrice revealed in Episode 1 one’s mana is that organism’s lifeforce itself, which is why the subs talked about regulation, and I’m guessing it should’ve been rendered as mana regulation.
When the group arrives at Mirula, which seems to be a town close to the Auguria Dunes, Subaru and Emilia meet a man at a bar who tells them that nobody has reached the Pleiades Watchtower in four hundred years and that the place is crawling with mabeasts and miasma, urging them to not attempt the trip. Despite hearing that, the pair aren’t at all perturbed, and before they depart, the man calls out to them and tells them about how locals have always seen birds headed toward the tower, so if they get lost they should follow a bird since it may show them the way. Subaru sees his metal leg, and it’s clear why the man told them what he did as he was genuinely concerned for them as Emilia had said earlier and just wants them to live life and be healthy.
Once they’re out there, Subaru prods Julius about his spirits, and Julius replies that the situation is the same as it was since his name was eaten in that his contracted spirits stay by his side but are perplexed by the situation since they do not remember him. The contract he made with them is still intact, but he cannot use them in battle, probably until his name is recovered from Roy Alphard should that be possible. Thus, Julius shares in that moment that he’s weaker in combat now although Subaru’s reaction proves that he’s not great at keeping secrets, which Julius already knew from spending more and more time with him. And of course, Subaru banters with Julius in a somewhat sour way when he says he doesn’t want to have the title of the one who understands him the most in the world after Julius put that out there, showing that Julius considers Subaru, just like in the previous episode, a source of strength since Subaru’s the lone person proving that he exists.
Then the sand time arrives, and it’s just a huge sandstorm with the group continually headed toward the tower yet making no progress whatsoever. Subaru is wearing something over his nose and mouth to pretend him from breathing in the sand, and Anastasia tells Subaru after he opens the window of the carriage that she will keep her promise since they’re in the same boat here, and Subaru obviously is pretty close to Beatrice given he shared that it’s Foxidna rather than Anastasia operating right now in that body even though he said that he didn’t want to tell the others and cause a stir when they least needed it, but it also reinforced Julius’s earlier point that Subaru’s bad at keeping secrets. Subaru then goads Meili into showing that she has been keeping the mabeasts from acting up by commanding a gigantic sandworm into nearly attacking them before harmlessly sinking back into the sand since he didn’t realize that Meili could command mabeasts with her mind, and that’s a very powerful skill.
Finally, Foxidna chimes in that it’s clear that they might be going in circles ’cause the space here is warped with the sand here not connecting to the Pleiades Watchtower, which she calls a distortion, clearing showing Foxidna has at least some of Echidna’s knowledge on magic, and she says that the sand time when the wind picks up is the recoil from space twisting and returning to normal, meaning that the periods between the sand times are when the distortion is weakening, and that’s when they can find the real path to the tower with the one best suited to the job being Ram since she can use her Clairvoyance, which was revealed in Season 1, to guide them to the right path by tracking the mabeasts’ vision. Mabeasts that are still active obviously came from where the real tower is since Meili has already tamed the ones in their vicinity, but Ram is clearly struggling, and then Foxidna remarks that she saw a bird feather, prompting Subaru to look out and tell Ram to see through the birds based on what the man from earlier told them, which is successful.
They then arrive to what seems like an endless field of flowers, which Meili states are the hideout of Oiran Bears, leading her to quickly tell everyone to can it since this is a mabeast that is difficult to control as most mabeasts she can settle down just with her mind, but with this species of mabeast since she needs to also make eye contact with it and command it with verbal gestures and repeating a tch sound to express disapproval. However, Joseph gets unsettled, resulting in them being chased by a horde of Oiran Bears, and once they’ve nearly made it past the flower field, Subaru gets his head blasted straight to pieces by a light from the tower. Upon Returning by Death, Subaru has no idea what happened, and the same sequence happens again except Subaru tells the group they can’t run straight for the tower, leading to Subaru, Beatrice, and Ram being separated from the group. Then that same light is shot at Subaru again, only Patrasche knocks Subaru partially out of the way before being killed, and Beatrice seeing how hurt Subaru is, tells him with tears in her eyes and an expression of great sadness that he can’t die and leave her alone since before Season 2 all she had experienced time after time again was loss with losing Echidna, Roswaal, Ryuzu Meyer, Petelgeuse, and probably others given in Season 2 Beatrice remarked that Petelgeuse left her too, which was one of the reasons she was suicidal and needed to be persuaded by Subaru to leave the Forbidden Library, which was burning to the ground as part of Roswaal’s mansion, since she was waiting for a person who she thought might never come. Then that same light kills Beatrice before a final shot kills Subaru.
During the third loop of this scenario, Subaru, thinking back to Julius calming down Joseph by stroking his neck before they departed, decides to use his Invisible Providence to calm Joseph down so that he doesn’t make a ruckus, leading to the Oiran Bears attack not happening, and he thought back to Beatrice first, so his not wanting Beatrice to cry and be in despair may have given him the inspiration to dig deeper for a solution. He also put his hands over Beatrice’s mouth during that incident, likely ’cause Beatrice would feel the air current from the hand emerging and potentially get startled, so he couldn’t have her crying out in surprise. He then remarks about a hunch of his about a light from the tower, and the group takes him seriously with Ram pointing her Clairvoyance to the tower and seeing a living being looking at Subaru before shooting something at him, which took the combined efforts of Emilia and Julius to stop, and the light ended up being a needle supercharged by magic, probably yang magic since a lot of yin magic involves debuffs like Shamac, making something powered up like up most likely an application of yang magic. Ram then notes that another needle is coming, and Subaru and Beatrice use their combination technique E-M-T, most likely named after Emilia as in “Emilia, my Tenshi (as in angel)”, which nullifies all other magic from the field generated, which protects them from the needle, but E-M-T also resulted in the distortion in space coming undone, resulting in the group falling to who knows where, whether it be back to the disconnected sand or somewhere else entirely.
Now the rest of my post will be about names or tangentially related to them. I have to give Tappei props for coming with the name Oiran Bears. Oiran is a collective term for the highest-ranking courtesans in Japanese history. The highest-ranking oiran, the tayū, had the prestige of being able to refuse clients, and the kanji for oiran consist of two characters, 花, meaning “flower”, and 魁 meaning “leader”.
Thus, this is almost certainly why Oiran Bears hang out under what seems to be an endless field of flowers and why they are hard to control even for Meili, and this is why making moderate- to-loud noises makes oiran bears go berserk, making them the “leaders” among regular mabeasts in the difficulty to control them even for mabeast tamers.
Tappei has often shown that he carefully considers how he names characters, whether it be due to the star lore (Subaru is the Japanese term for Pleiades, which is also referred to as the Seven Sisters, which is why the seven deadly sins is an important part of the story), plot details (Otto refers to attar, which is a fragrant essential oil, and Otto bought a bunch of oil out of season that he desperately needed to sell), personality traits (Petra means ‘stone’, and she is fearless considering she told the others to abandon her when Elsa took hold of her), mabeast species traits (Guiltylowe has “lowe” in it referring to lion, which is why a Guiltylowe has the head of a lion), character roles (Wilhelm means “resolute protector”, and he did devote his life to ensuring Theresia fought as little as possible), character powers (Betelgeuse means Orion’s hand, which is why his power is Unseen Hand), and names in relation to others’ names (Frederica and Garfiel and Fred and Rafiel to show that Liara subconsciously remembers Garfiel and Frederia), so I’m sure this is another instance of that. Well done, Tappei, my man, in giving that species of mabeast an intriguing name that fits the traits it was given.
As for the name of the Sage, Shaula, it’s a name of Arabic origin translating as the raised tail of a scorpion. It’s also a star representing the stinger of the Scorpius constellation, which is likely how Shaula came to have that meaning. Let’s see whether this is referring to a power, lore, or something else. Tappei surely has cooked up something good for Shaula.
As a reminder from Seasons 2 and 3, Baten Kaitos meaning “belly of the whale”, Alphard meaning “the backbone of the serpent, and Arneb meaning “hare”, likely meant that each of them could control one of the Three Great Mabeasts, which is why Lye referred to the White Whale as our pet since the Sin Archbishops of Gluttony speak as if they are a unit. I’d hazard a guess that Meili cannot control any of the Three Great Mabeasts.
And since Subaru itself is the word for Pleiades in Japanese, the Pleaides Watchtower bearing his name is interesting. We’ll see what’s in store. It could indicate that the Pleiades Watchtower itself was planned to be built with Subaru’s arrival hundreds of years later in mind, meaning it may have been part of the plan the heroes from four hundred years ago I propose made to bring the world to a free future as alluded to Melakuera talking about the world imbalance and the Witch as well as him facing world ending crises countless times, suggesting that the world is stuck in a cycle of being destroyed by the Witch of Envy and reconstructed with Subaru being the one they hope will break this cycle.
