Regardless of how you personally feel about Guts' present torment, the excessive amount of time he’s been left in this state is telling of
an information gap. Instead of advancing his narrative, the Continuation stretches out the known beat—Guts being distraught over losing Casca and suspecting the boy as another of Griffith's ploys—as long as inhumanly possible until the next major moment that truly involves him, and is known to Mori, actually arrives. Who knows when that will be?
And I want to clarify that I am aware the Continuation is not executing the story beat as Guts being upset about Casca and his son in any way, shape or form. I'm just thinking about how Miura would've done it.
Guts is essentially in stasis; no meaningful character development is occurring. It feels as if Miura intended for him to be doing something else at this point in the story.
I toyed with the idea before, and so did the SkullKast, that Guts might be separated from the group right now, a decision (Guts' own decision) that could be driven by
a major incident involving the Berserk's armor.
Several narrative cues leading up to, and within—Elfhelm could support this observation:
1. Skull Knight's our guy, but he's a harbinger of calamity and is now at the island, possibly in expectation of
something (He did park his horse!). His ominous warning about converging causality foreshadows a major development on the island, and it finally came on Episode 364.
2. Numerous hints during the sea journey suggest that Guts’ inner beast is poised to emerge whenever one of his companions is hurt or lost, and that next time Schierke would be powerless to stop it.
2.1. So Many Developments About the Armor—All Right Before the Boy’s Arrival
We could have seen more of Hanarr, but that didn’t happen—at least, not yet. Gedring discusses the armor with Guts, but the conversation doesn’t delve deep enough. All of this feels like it’s building toward an inevitable breaking point.
Before these threads can be satisfyingly resolved—before solutions are found—it would have been crucial to see the worst-case scenario play out. Miura teased Guts losing control for so long that he *had* to deliver eventually, and I can’t imagine it happening
after the island, too much of a distraction when clearly the final stretch was commencing.
3. Other beats at sea where Guts ponders setting out alone to confront Griffith once Casca is healed (He even has one of these moments right before seeing the boy in Episode 363!) He was going to have to act upon it at some point, and hey, what better moment than now? Nothing more to lose.
4. Finally, Elfhelm—a refuge of magicians and elven entities beyond the scope of the God of the Abyss—couldn't be left standing. Some of us were expecting a War Demon raid on Skellig, but it's so much simpler for Griffith to have bided his time and exploit the transformation as a perfect infiltration point (Pure speculation. Just rationalizing how the Fall of Elfhelm was seemingly telegraphed).
Put all these elements together, and it's likely that Guts was set up to fail at attacking Griffith (As we saw). But it wouldn't have ended there—the Beast would have taken over, unleashing catastrophe.
Based on how the Continuation recycles elements we've seen in the past (See the trolls as of recent), I just can't buy the idea of the gnawers tearing the island apart. It's
fanfiction.
Here's my take: Guts wreaks havoc in paradise, and it topples over.
Though my idea is
also fanfiction, lately I haven't been able to shake the mental image of Guts, burning with raw fury, senselessly attacking the cherry blossom tree with the Dragonslayer, cutting it down with unstoppable rage, yet unaware. Griffith is out of reach, he popped in and out with Casca in arms, Guts' wrath would be uncontained and it would've been directed towards
something... And it would showcase his rage to the reader without having him kill a main character, that would be unsatisfying.
... He just swings and swings and no one could stop him. And if we accept that Gaiseric's lady was buried beneath that tree, and that her connection to it somehow allowed Danan to exist, then the tree's physical destruction would explain her disappearance in a way that makes a lot more sense than the Continuation's explanation (None at all).
Guts would have been absolutely torn up inside after all of this, yes. More than ever.
But he would've stood up, and go forth to try to figure this out his style and without desiring to cause his friends more hurt. He would've had a lot of learning to do: Think over Gedfring's words, find his ideal relation to the armor, tame the Beast, come to terms with the fact the boy is his Son. Once he had worked towards these goals, then the character would've been ready to regroup with the others and bring everything to a closer.
I also believe that Guts and the others exploring the mainland separately would've been a great way to flesh out the world of Fantasia even more, which is also what we were expecting in the future. It makes me wonder though, who would've been the one to find the Bakiraka hideout first?
