Re-reading the episodes "Spring Flowers of Distant Days" where we see Guts before meeting the Band of the Hawk when he encounters a flower spirit named Chich, I wonder what the purpose of including this 3-part flashback was?
Miura said at the time that he had wanted to show a bit of Guts' journey during that period for a long time. He also wanted to explain why Guts is uneasy around Puck when they first meet, repeatedly telling him not to touch him.
While the death of the flower and disappearance of Chich and the death of the tree and the disappearance of the ethereal creatures on Elfhelm (save Puck and Ivalera) seem to share little in common, it still seems as if there was meant to be some kind of connection or relation between the two phenomena or story themes, because it does not seem like there's enough story left the way we are moving towards the end that would pay off what we saw being set up with Chich if it wasn't that.
When we first saw that little segment of the story, it was immediately apparent to me that Chich's nature as an elf tied to a flower was significant and that it might perhaps relate to the Sovereign of the Flower Storm. So yes, I think it was something Miura intended to do, but his untimely passing meant we did not get to see it. What's left to be told of the story doesn't really factor into this, since we also will not get to see what Miura intended to do. It will at best be a dumbed down approximation of some of the major beats.
Maybe the point of Chich was so that Guts would meet her again if the disappearance of Danan and the Elfhelm creatures is resolved by bringing them back somehow from wherever they went
I don't think so. It's implied Chich passed away.
He didn't seem to pay any attention to Danan or the creatures disappearing and was not even really there to witness it, it's hard to imagine him caring that much with everything else going on
I recommend you to refrain from ascribing too much importance to character reactions (or absence of reaction) in the continuation of the story by Mori and Studio Gaga. Keep in mind it's – at best – a shadow of what Miura would have done.
Let's ignore any speculation about Guts' beherit for the moment
Yes, that'd be for the best. I don't think Guts is going to sacrifice someone (reminder: Casca is already branded) just so he can become an official, causality-ordained minion of the God Hand.
Are Apostles still being created around the world since the beginning of Fantasia by use of behelits and sacrifices? And how would that work for Griffith exactly who has incarnated into the physical plane, does he still get pulled into those ceremonies on a regular basis or at all?
When Balzac summons the God Hand in the Dreamcast game, Femto is not among them. So no, Femto hasn't been involved in those ceremonies since he was incarnated. Not that it matters much. As for whether apostles are still being created using beherits or not... Same thing, really. It could matter in the long run, but it's not an immediate concern in the story. I'd say there are more important questions, like if more apostles are needed at all, or if their production might not end up being "industrialized" in Falconia eventually.
Did Miura intend to explore the despair of someone who would not even receive the "gift" (or curse) of a behelit helping them, and how they'd get out of it on their own?
Characters feeling despair isn't exactly novel in Berserk... And it doesn't always lead them to become apostles. I don't find this train of thought to be very pertinent.
The story has moved away quite a bit from this theme or idea of humans being seduced by demons that seemed to be a major one at the start of Berserk
Practically the entirety of mankind is currently enthralled by Griffith and living in the fantasy city, fashioned in his image, that he conjured up. He's both their military leader and main religious figure as well as de facto ruler. So I'd say the theme of "humans being seduced by demons" is stronger now than ever.
We have not seen any ceremony when an Apostle is created apart from brief flashbacks, except for Griffith - which was also a flashback and dealt with a Godhand ascension rather than Apostle creation.
We see how it works in volume 3. Personally I've never felt that we were missing on it or anything.
Now, about the inconsistency or "out of character" aspect of Guts as he does not even attempt to move while being carried onto the boat in this episode. Could the barytes have anything to do with it?
No, absolutely not.
I assume "causality" in the world of Berserk is not the same as the cause and effect of our world, that it is not simply random but acts with some sort of purpose and possibly through the use of barytes (almost like an "infection" since elementals seem to have agency and are not just passive forces of nature).
I don't think that's correct, from what we know of the story and how things work in Berserk's world.
Speaking of barytes, I like the theory going around that the Berserker armor works through barytes elementals and the reason it didn't activate (and possibly can't activate in proximity to Griffith) is because Griffith swallows the barytes into his torrent.
Seems completely far-fetched to me. If that were what happened, I think we've have seen a hint of power being sapped away from the armor, which isn't how it went. Besides, it doesn't seem like using the armor would have made much of a difference against Griffith in that particular context. Striking faster and stronger doesn't matter if you can't hit the target. Which gets me to the obvious point: the maelstrom around Griffith is why he's untouchable, it's not merely to prevent that one magic armor from activating.
As before, I would caution against trying to find deep meaning in the minute details of those episodes. Keep in mind Mori and the staff only know a bit of what Miura intended to do, and they don't necessarily know
how he meant to do it either.
It would be a neat way for Miura to have Guts not lose his mind to the armor whenever he confronts Griffith towards the end of the story.
That doesn't seem like a very interesting development at all to me. If your thought is that they ought to have a talk, then there's many other and better ways for it to happen than "your armor can't activate because my magic powers block it!"
The armor is useful when confronted with monsters and Apostles, but it seems unlikely to really add anything to a fight with the actual Godhand members, so having it be automatically disabled in such situations might be a blessing.
I'd say the armor would be more useful than not even in a fight against the God Hand (provided Guts can land a hit). It's not like his previous fights against them with his older gear have gone very well.
We know what happened to King Gaiseric when using it against the Godhand.
We don't know all that much about it, actually.
Anyway, going back to the recent fight between Guts and Griffith, we see a panel that looks like Griffith noticing the Beast of Darkness. I wonder if this is something Griffith picked up on while possibly absorbing barytes elementals from the Berserker armor, just poorly drawn or conveyed by Studio Gaga without Miura?
As stated earlier, I recommend you to refrain from ascribing too much importance to character reactions (or absence of reaction) in the continuation of the story by Mori and Studio Gaga.
By the way, a note on Casca's brand not spraying blood in such close proximity to a member of the Godhand... Was this not already an inconsistency back during the eclipse when Femto raped Casca? Her brand didn't do more than bleed a little back then either.
No, it's not. During the Eclipse, you can actually see the brand start to bleed over time, from panel to panel, as it becomes active.
