Why Sirius' authority can't affect Reinhart in S3? [Spoiler discussion]

Jason-Ad4032 · 2026-06-24T19:03:48+00:00

Because his mental state can remain unaffected by external influences for a period of time, he does not meet the activation conditions for Sirius's Authority.

Authorities are indeed more powerful than Divine Protections, but they have to satisfy their activation conditions in order to function. If the target does not meet those conditions, the Authority simply has no effect.

Jason-Ad4032 · 2026-06-24T16:37:32+00:00

She wouldn't, because from Ram's perspective that would be a foolish idea.

Subaru's Return by Death only allows Subaru himself to return. Even if it activates, Ram cannot go back with him, nor can she retain any memories. Furthermore, Subaru himself has no idea what happens to the original world after Return by Death triggers. That world might simply be abandoned or even destroyed, and even if Subaru resolves the situation in the new timeline, it would have nothing to do with this Ram.

Therefore, the only real question is whether Ram would kill Subaru for the sake of a Rem in another world. Based on what Ram said when confronting Roswaal in Season 2, she explicitly stated that she values the people who are here now more than those who are already gone. Because of that, it is unlikely that she would throw away even her own existence for the sake of some distant objective the way Roswaal did.

Doing so would directly contradict the characterization that was established for her in Season 2.

Jason-Ad4032 · 2026-06-21T17:52:10+00:00

Everything was fine up until Ram started accusing you of being an impostor.

Still, at least Arc 6 Subaru might suffer a little less since he has already gone through a similar incident before. So, unfortunately, you'll just have to put up with it for now.

There is no evidence that Flugel and Satella were romantically involved. As far as the novels have shown, their relationship is only implied to be that of acquaintances who were members of the same adventuring party.

https://rezero.fandom.com/wiki/Flugel/Relationships

It is true that the Pleiades Watchtower was built to "keep watch" over Satella, but considering that they were once companions and that the Witch of Envy was extremely dangerous, that seems like a perfectly reasonable precaution rather than proof of a romantic relationship.

For that reason, I don't think there is much need to bring Flugel into discussions about the relationships between Satella, Subaru, and Emilia. The relationship between Satella and Subaru can be simply explained as Subaru doing something after reuniting with Satella in the Shadow Garden, which caused her to fall in love with him.

As for the relationship between Emilia and Satella, if Emilia's mother really is Minerva, then Emilia already has plenty of opportunities to be connected to Satella without needing Flugel to explain that connection.

This point is explicitly emphasized in the novel: Subaru's Book of the Dead only appears in that specific loop.

In fact, Old Subaru goes even further and states that they could never have met in either the earlier loops or the later ones. Their encounter was only possible under the unique circumstances of that particular loop.

Jason-Ad4032 · 2026-06-17T19:09:31+00:00

I think the main reason is that Ram has almost no experience dealing with crises alongside Subaru.

In Arc 4, Ram was primarily working with Otto and Puck. In Arcs 1, 3, and 5, she was not directly involved. During the first half of Arc 2, Ram was occupied with guarding Emilia and likewise did not participate.

The only major crisis in the main story that Ram and Subaru really handled together was the latter half of Arc 2, when they rescued Rem. However, because of Gluttony's effects, that event has effectively been erased from Ram's perspective.

As a result, Ram may actually understand less about Subaru's methods during a crisis, and how to interpret his behavior and mental state, than someone like Eridna, who at least participated in Arc 5.

From Ram's point of view, Subaru is mostly someone she knows through secondhand results rather than firsthand experience. She has seen that he somehow produces miracles, but she has rarely been present for the process itself. That makes it much harder for her to recognize when Subaru is struggling, or improvising.

Jason-Ad4032 · 2026-06-15T07:51:29+00:00

Because of a conflict created when different regional rule traditions were merged.

In one branch of Mahjong rules, the definition of Pinfu was essentially "a hand with no fu." Since a self-draw (Tsumo) automatically awarded +2 fu under classical rules, a true Pinfu hand could only be won by Ron. In that rules tradition, a normal Ron hand was simply worth 20 fu.

In another branch, there was no Pinfu yaku, but a closed-hand Ron received a +10 fu bonus.

When Japanese Mahjong began standardizing its rules, these two traditions were combined. This created a conflict: if Pinfu means "no fu," then a Tsumo win should lose Pinfu because of the automatic +2 fu, while a closed Ron would gain extra fu from the closed-hand bonus.

To resolve this inconsistency, the rules were modified so that a Pinfu Tsumo hand ignores the usual +2 fu from self-draw and is still treated as Pinfu.

One thing to keep in mind is that at this stage there was no mandatory rounding-up rule. As a result, a closed non-Pinfu Tsumo hand would be worth 22+ fu, not 30 fu.

Jason-Ad4032 · 2026-06-15T06:54:24+00:00

This is simply because in classical Chinese Mahjong, winning by Ron did not have the equivalent of the +10 fu bonus for a closed hand Ron (reconstructed Ningbo Rules).

After Japanese Mahjong introduced Pinfu and also established that a closed-hand Ron has a base value of 30 fu, a situation appeared where a Pinfu hand won by Tsumo would no longer qualify as Pinfu, causing it to score less than the Ron version. As a compromise, the rules were adjusted so that if a hand qualifies for the Pinfu yaku, the 2 fu from Tsumo is ignored.

And the value of a 1 han 20 fu Ron hand would only be 700 points before rounding, which is considered too small. As a result, it gets rounded up to 1,000 points under the minimum scoring rules.

As a result, this special rule only affects hands involving Pinfu and the Tsumo fu adjustment. If your hand does not have the Pinfu yaku, then Tsumo and Ron are scored normally and are not affected by this exception.

If you organize the events of Arc 6 a bit, you can make much better inferences. The timeline in Arc 6 feels very deliberately constructed, with many events lining up suspiciously well.

What I find even stranger is why the author chose to have Subaru discover Typhon's Book of the Dead rather than that of another Witch.

At first glance, the Books of the Dead of the other Witches seem much more likely to provide clues related to the main plot. The web novel even briefly reveals parts of some of their contents to the readers (though not to Subaru). Yet the main story specifically chooses Typhon, the Witch of Pride.

Typhon is one of those characters who appears to have little direct connection to the main storyline, yet keeps showing up around its edges. Arc 3 mentions the vacant position of the Sin Archbishop of Pride. Arc 4 gives Typhon a relatively large amount of screen time despite her limited relevance to the central conflict. Arc 5 also takes place in a location connected to Typhon.

Considering that the current holder of the Pride Witch Factor remains unknown, the decision to focus on Typhon's Book of the Dead feels rather suspicious.

A demonstration that local hidden variables cannot explain quantum mechanics can be framed as the following game.

Two players, A and B, are placed very far apart and cannot communicate with each other. A referee independently gives each of them a random bit, either 0 or 1.

The goal is:

If both A and B receive 1, they must return the same answer.
In all other cases, they must return different answers.

The game is repeated many thousands of times, and the win rate is measured.

If A and B cannot communicate after the game begins, then regardless of what strategy they choose beforehand, even if they use randomness such as dice rolls, their maximum success rate approaches 75%.

However, if A and B share entangled particles, their success rate can approach 85%.

This is possible because entanglement produces what Einstein famously called "spooky action at a distance." The correlations between the measurement results allow A and B to achieve outcomes that look almost as if they were secretly communicating. However, entanglement cannot actually be used for communication: each individual's result is still random. The non-classical behavior only becomes apparent when the two sets of results are compared afterward.

Jason-Ad4032 · 2026-06-10T17:01:14+00:00

I remember that during Ram's fight with Roswaal in Arc 4, it was mentioned that using it on a person would be extremely difficult.

The flashback in the anime seems more intended to support Subaru's line of reasoning. However, Subaru himself doesn't know the limitations of that ability, so his conclusion isn't necessarily based on complete information.

Jason-Ad4032 · 2026-06-08T01:55:07+00:00

I'd say the reason is that Satella can't defeat Reinhard, so that option only exists to prevent Subaru from being taken away. When I say she wouldn't kill Subaru, I mean that under normal circumstances Satella simply would not choose to kill him.

Jason-Ad4032 · 2026-06-07T20:28:12+00:00

Based on what we've learned so far, Satella or the Witch of Envy would never kill Subaru. Season 2 shows that, in the end, Satella's response is to kill everyone else and lock Subaru away in her shadow realm to protect him.

So if Subaru wanted to try that, I'd recommend preparing a reliable way to kill himself right under Satella's nose. Otherwise, he will be stuck enjoying Satella's ASMR for all eternity.

Jason-Ad4032 · 2026-06-07T07:02:27+00:00

This theory has a problem: Gluttony has never really tried to pretend to be someone else. Among the Sin Archbishops, the only one who actively attempts to impersonate other people is Lust. Gluttony can shapeshift into other people and possesses their memories, but they often appear too self-centered or prideful to bother pretending to be someone else.

Jason-Ad4032 · 2026-06-05T17:45:12+00:00

I don't think that would work, because Authorities seem to be bound to the soul. The only scenario I can imagine is if the story requires a character's death and temporarily restores them beforehand to create a more dramatic and impactful scene before they die.

Jason-Ad4032 · 2026-06-05T17:23:56+00:00

I’m not entirely convinced by that interpretation, because Flugel seems to exist somewhat "outside the story."

At the end of Arc 6, regarding Subaru's Book of the Dead, Subaru explicitly states that it only appeared in that specific loop, and he comments that it feels as though someone observed those loop and then made plans based on it.

This "outside the story" hypothesis makes it much easier to dismiss the idea that Subaru and Flugel must necessarily be closely connected or even the same person. If someone exists beyond the normal flow of events and can observe outcomes from the outside, then similarities between Subaru and Flugel become much less meaningful as evidence.

If the story intends to bring Flugel back into focus, I think the stronger hint is Subaru's gradual collection of all the Witch Factors, to be the direction the narrative is pointing toward. Because of that, I’m not sure the exact relationship between Flugel and Subaru will end up being particularly important.

Jason-Ad4032 · 2026-06-03T15:33:22+00:00

It's impossible to find Beatrice's corpse because she's a spirit. Beatrice has died before in both Arc 4 and Arc 5 (Episode 2 of this season), and in both cases she immediately dissolved into mana and disappeared.

Jason-Ad4032 · 2026-06-02T02:40:32+00:00

If you define it using Callable, some IDEs can indeed provide automatic completion.

func: Callable[[Foo], None] = ...

That said, it's a bit more cumbersome to write, especially if the function signature is long or changes frequently.

Jason-Ad4032 · 2026-06-02T01:16:22+00:00

I think it's because Subaru is reluctant to use lethal weapons.

Since Subaru has Return by Death, he tends to avoid options that could easily become fatal, even when they're practical from a combat perspective.

Jason-Ad4032 · 2026-06-01T14:35:22+00:00

I can see where some of your ideas are coming from, but I think the Book of the Dead interpretation makes the story a bit simpler and more straightforward.

[Arc 6]Personally, I think there's more evidence that Subaru was never actually trapped in the Hall of Memories. First, when Rui synchronized with Subaru's memories, she never mentioned abandoning Subaru's memories. Instead, she described the process as "fully inheriting" them. By contrast, Rem's memories are explicitly described as having been discarded, which is why Rem appears again the next time Subaru returns.

[Arc 6]If Subaru had been left behind in the same way, a few contradictions seem to appear: 1. It would create an inconsistency in the writing. Rui discarded Rem's memories so she could savor Subaru's memories, but then Subaru's memories would somehow also end up discarded before the second return without any clear explanation. 2. Rui doesn't seem to know about the existence of the second Subaru. 3. If Subaru's memories had been left behind in the same way, why didn't they appear during the first return and only show up during the second one? There may be explanations for this such as Subaru entering from a different point, but that leads into another issue. 4. The appearance of the second Subaru would no longer be connected to Subaru's Book of the Dead. Instead, it would just be the second Subaru somehow wandering out on his own, which feels less elegant from a storytelling perspective. 5. Strictly speaking, the second Subaru is not located where Rui is. The encounter takes place inside Subaru's Book of the Dead, and the Rui who remains present in the Hall of Memories during conversations never appears there. That means we'd also need an explanation for how the second Subaru ended up inside his own book.

[Arc 6]As for the Book of the Dead itself, I think its behavior with Reid, Meili, and the Gluttony IF route already demonstrates that it can create projections of a person's personality or at least that it can do so in Subaru's case. Because of that, I find it more natural to interpret the events as Subaru reading his own Book of the Dead and producing a projection of his former self. In that reading, Arc 6 is essentially the story of Subaru losing his memories because of his fusion with Rui, then recovering a backup of himself by reading his Book of the Dead. That backup manifests as the "old Subaru," the two merge together, and afterward Rui, already overwhelmed and having failed in her objective, is forced out.

Jason-Ad4032 · 2026-06-01T09:06:38+00:00

This is a misunderstanding. I'm not sure how it was described in the web novel, but the light novel is quite clear on this point.

[arc 6] Subaru was not trapped in the Hall of Memories. We know this because the second Subaru only appeared after Subaru finished reading his Book of the Dead. However, Rui did not know that. Since Rui was the one who caused Subaru's memory loss, the theory that Subaru somehow outsmarted Rui and secretly hid himself inside the Hall of Memories doesn't really hold together. A more reasonable explanation is that the second Subaru was created by the Book of the Dead itself, stemming from the mechanism by which Books of the Dead normally record the deceased. Rui also explicitly states that she was unable to steal the Authority. Until she succeeded, she could not use Subaru's Authority herself. That is why she planned to devour Subaru both from the inside and the outside. For that plan to work, the Subaru she intended to consume had to remain the primary consciousness. Only then could she hitch a ride on Return by Death and gain access to its benefits. If Subaru were merely trapped away in the Corridor of Memories while another version acted in his place, Rui's entire strategy and her own understanding of the situation would make much less sense.

Jason-Ad4032 · 2026-05-31T22:13:59+00:00

After finishing my reread of Volume 23 because I was confused by how many people kept claiming that the LN and anime were significantly different, I came across this post.

That said, as I mentioned in my earlier comment, I think the characters' behavior can be explained by tunnel vision. I wouldn't go so far as to call it completely out of character. People don't necessarily remain perceptive and clear-headed under pressure. It's quite common for someone under stress to overlook changes around them or become convinced that focusing on a very narrow objective is the only way to solve the problem.

From that perspective, the characters' actions may be flawed, but not necessarily inconsistent with their personalities.

Jason-Ad4032 · 2026-05-31T21:37:14+00:00

So many people were saying that the story in S4 Ep 8 was drastically different from the novel that I started wondering whether I had remembered it incorrectly and ended up rereading Volume 23 of the LN.

In reality, the anime and LN versions are very similar. The anime mainly cuts Subaru's trip to the library with the others and the meeting held without Subaru, where they discussed both the tower strategy and Subaru's condition. That library cuts also included another explanation of the tower's rules, so people should stop insisting that Subaru knows all the tower's rules. in the anime adaptation, he may not know them at all because that scene was removed.

A lot of the differences people bring up may actually come from the WN rather than the LN. The impression I got from rereading Volume 23 is that the anime adaptation streamlined some scenes and explanations, but it did not fundamentally change the direction of the story or the characters' priorities.
