Deltarune Theory: Bones Bared
Well, Deltarune chapter 5 is almost out, which blows a massive hole in a theory video I was working on, since I won't have enough time to actually make this behemoth into video form in a week. As a compromise, you're all getting my hastily edited draft on tumblr so that I can at least have it out before release.
To start with, I was wondering about the games established Gaster/Gerson parallels. They are both entities that βfell into their creationβ, who are able to commune with people through the medium they fell intoβ for Gerson, his writing, for Gaster, the dark world. But to complete the parallel implies that Gaster has some kind of equivalent to Alvinβ someone who brought him here and gave him the ability to interface with the world at large, but refuses to finish his work.
The fact that Gasterβs theme is called βAnother Himβ strikes me as interesting, because it implies that βhimβ from undertale is the theme of a different Gaster.
It also feels obvious in hindsight that there would be another Gaster. After all, anyone who is at least a little familiar with his lore knows heβs from the undertale timeline, which means that deltarune!gaster is completely unaccounted for.
Iβd go through the list of all the possible suspects for deltarune!gaster, but the obvious culprit is the forgotten man as the only other mysterious, explicitly male gendered character we get. However, I also think the forgotten man is Papyrus, so rather than entertaining other suspects, I figured Iβd get out the corkboard and red string and hope that whatever I tied together would produce a coherent image instead of a monochrome smear.
CASE 1: Papyrus and the Forgotten Man
A bunch of people beat me to finding the evidence that papyrus is the forgotten man, but Iβll go over it again so weβre on the same page.
The most obvious bit is the egg in his dating sim hud
But thereβs also the reference to dinosaurs in the chapter 3 egg roomβ Dinosaur Egg Quaker Oatmeal being Papyrusβs favorite food.
As an additional point, the only character in Undertale who is aware of this is Flowey, who can reset timelines, implying that his acquisition of this information was through some kind of random event.
One of the snowdin puzzles consists of Papyrus shoving a bunch of snow around to make the shape of his face. If you ask him for the solution, heβll tell you to press a button behind a tree, solving the puzzle.
Thereβs also a few references in the genocide route that are more than a little eyebrow raising.
Compare
to
Not to mention the βForgettableβ as his act description.
Papyrusβs phone dialogue has a lot of eyebrow raisers as well.
Thereβs also this bit of phone dialogue that Iβve been eyeing since I ran into it:
In deltarune, every trash darkner is named trashy, implying that Papyrus has been to the dark world version of his own house.
This feels especially significant considering you need to use an escape ticket on a ribbick to reach MANCOUNTRY, a mob that canonically lives in a garbage can.
In order to get this far, you also have to interact with a Bibliox, which is a misspelling of byblos, which is greek for Papyrus.
While not strictly being evidence, I think Papyrus being an out-of-work child psychologist also recontextualizes his character in undertale in a lot of interesting ways.
Itβs not unheard of for adults to be friends with teenagers, but it makes a lot more sense that sans would choose Kris for Papyrus to hang out with over say, Alphys or Undyne, if his brother specializes in working with children, especially if Kris was one of his former patients. Which is to say nothing of Flowey, who is the child psychologist equivalent of handing an understimulated tiger at the zoo a watermelon.
Iβll wait to the end to get into what Papyrus being the forgotten man could further imply, but I did want to draw some attention to this the forgotten manβs 2024 valentine to segue to our next point:
Who was the forgotten man trying to help?
There are three potential culprits here, so Iβll start with the one we have the most exposure to: Kris.
CASE 2: Papyrus and Kris
Letβs start with their most superficial similarities: their appearances.
While their outfits arenβt one to one, I think itβs interesting to note that Papyrusβs armor covers all the same areas of his body as Krisβs does, sans the blue underwear. Rather than covering their entire chest, Krisβs chestplate only covers their ribcageβ a fact that feels intentional when you consider the prophecy refers to them as The Cage, which stands true for Papyrus too as a skeleton. His outfit doesnβt cover his midriff.
As an aside, it also got me thinking. βThe Cageβ needs a human soul and parts, but the prophecy never strictly said it was human. A skeleton isnβt a human, but it is unambiguously a human part. Considering Kris can survive without a soul for a certain amount of time, and monsters can absorb human souls, it does beg the question of whether or not Papyrus could fulfill the role of the cage if tasked with doing so. Itβs not something I imagine will come up in the game proper, but think it would be really funny if it did.
They also both have capes that are different shades of red, which ties what might otherwise be tenuous similarities together a bit more.
Papyrus is a shoddy reproduction of Krisβs outfit, though I think thatβs the point. If this is supposed to be Krisβs outfit, then itβs blatantly supposed to be a bad cosplay created from Papyrusβs equally bad memory. Considering that Papyrusβs stupid underwear has a similar silhouette to the roaring knightβs, though, I think thereβs a nonzero chance that Kris and Papyrus might just be borrowing visual motifs from the same third party as opposed to each other.
There's also their shared hatred of anime.
On its own these similarities are a little vague, but thereβs one Iβm a bit more invested in: their random bouts of memory loss and depersonalization.
Granted, this is a running gag for Papyrus, but it's not like Toby's never foreshadowed anything through a joke before.
They both seem to be experiencing memory loss as well. For Kris this is associated exclusively with the forgotten man and whatever caused Dess to disappear, whereas Papyrus instead seems to struggle to get a grip on his surroundings all the time, though granted the most concrete example of this is also from cut content.
The interesting distinction to me is that this is a trauma response for Kris, but a simple fact of life for Papyrus. For Kris this is an incident that is being erased, along with everything associated with it, whereas for Papyrus his entire existence seems to be a cycle of forgetting and remembering, as if existing itself is the thing he wasnβt supposed remember.
I feel like parallels open themselves up a bit more clearly when you open up a sibling quartet, though. In some ways, sans and Papyrus directly mirror Asriel and Kris.
Most notably, sansβs room is in a similar state to Krisβs side of the bedroom, while Papyrusβs room is on the same side as Asrielβs. However, sans has an established social life, like Asriel, and Papyrus is regarded as the local weirdo, like Kris.
All in all, the evidence towards Kris being the person the forgotten man is trying to save is borderline nonexistent, though some inexplicable parallels with Papyrus have me squinting anyway. βSaviorβ doesnβt feel like the word for their dynamic, though thereβs plenty of room in future chapters for tricky tony to prove me wrong.
As the only two characters who have canonically interacted, however, Kris and the forgotten man donβt strictly need a strong narrative connection for this to be the correct answer. The most straightforward solution may be the correct one, though I think itβs more likely that their connection lies in them chasing the same mystery: Dess.
CASE 3: The Forgotten Man and the Knight
Dess has a lot more going for her as the person the forgotten man is attempting to save, but the caveat is that the evidence has a lot more βifβs to it. The big one is the assumption that Dess is the knight, but if youβre in any way familiar with Deltarune fan theories you should have seen that coming by now.
Theyβre both siblings who are suspiciously absent from the first half of the game, and their respective siblings are practically mascots for the bad routes for undertale and deltarune respectively. Both Papyrus and Dess have been mentioned by name but never physically shown.
The determination extractor is also inexplicably shaped like a deer skull, and the true lab gets us an early forgotten man easter egg.
(I've hit Image cap so you're just gonna have to imagine it)
If Iβm going to have a bit where I assert Kris and Papyrus share visual motifs just because of a cape, then I also feel remiss to not point out that the roaring knight is a deer skeleton specifically, one whose silhouette is noticeably Papyrus shaped.
The most common assumption I see made about the roaring knight is that her skeletal form is a sign of her body decaying, but monster bodies turn to dust immediately, so that justification falls apart instantly from a watsonian perspective.
Itβs also kind of hard to say whether or not monsters even have bones, given the current discourse over whether or not they even have blood.
However, it has been heavily established that monsters from the same family are always the same species. Considering the big stink the plot makes about Krisβs body dysmorphia over not having horns, I think itβs actually fairly likely that Dess on some level subconsciously regards herself as a surrogate part of the skeleton family and alters her cool knight form to match.
A hidden piece of xbox shrine dialogue also establishes that Papyrus canonically loves snow, an extremely holiday family trait. He also seems to forget it snows every time it does for some reason. From the sound of it, he also went out of his way to get to know Noelle, Dess, and Monster Kid in Undertale. Considering sansβs relationship with Toriel carries over between both games, itβs fairly likely that Papyrus had a relationship with the Holiday family in the deltarune timeline, too.
Itβs a bit semantic, but I also feel the need to point out that in chapter 1, sans says βwe just moved here, so i hardly know anyoneβ and not βwe just moved here, so we hardly know anyoneβ, leaving Papyrusβs relationship to Hometown surprisingly ambiguous. In Undertale, Papyrus also says his house is "technically sans's too" which further implies that he is at least the owner.
The meat of this, however, is in the unused deltarune text. Like a lot of people, I think Dess is the one saying this, but there are some connections to the forgotten man I want to point out anyway.
I always did have that nightmare. Walking into the darkness, With the light shining from the doorway... Then the door slams behind me. And everything goes black. ... is this that nightmare? ... or was everything else a dream?
This is a reference to the opening of Magami Ibunroku Persona, who apparently got it from some guy named Zhuangzi.
In Persona, this quote is made in reference to the charactersβ, well, Personas and their relationships to the surreal landscapes they end up going to, which is one of the reasons Iβm not super pressed about the whole βif Dess is lost in the code then how is she also the knightβ thing. The same thing happened to my good friend Maki Sonomura in 1996. though I think an analysis for what this implies about the themes of Deltarune are better left to someone who actually knows things about Taoism.
Whatβs relevant to this conversation is that the forgotten man talks in this recursive way of speaking all the time. Itβs a sort of typing quirk of his, I guess you could say.
To clarify some ground rules for the people who are inevitably going to go looking for them after this, for it to count as a butterfly dialogue it has to follow a βIs x y or is y xβ type syntax, if not explicitly then implicitly. The subject and the speaker need to switch by the final sentence.
Unfortunately examples for butterfly dialogue in the forgotten manβs dialogue is like. all of it, but I think the most noteworthy ones are at the end of the chapter 4 egg room (where the rudin asks if weβre the patient or the doctor) and the valentines message we were here to analyze in the first place.
(Again I'd post examples here but I'm out of pictures)
The unused text has a syntax too different from the way the forgotten man speaks to be him. But almost every other reference in this vein is in regards to the forgotten man or the prophecy itself. From this I can only really conclude that whatever happened to the forgotten man also happened to Dess. Or whatever happened to Dess happened to the forgotten man.
On the subject of Papyrus, he also has a few lines of dialogue where he mentions he doesnβt sleep very much. He also refuses to go to sleep unless sans is there, too, which makes it fairly plausible heβs having the same kind of nightmares that Dess did and is avoiding sleep altogether in order to not deal with them.
The last parallel also brings us to our final (albeit least likely) candidate for who the Forgotten Man was trying to save: Undyne. Sheβs the knightβs first captive, but also the first person Papyrus actively befriends in the underground, a fact that doesnβt strike me as entirely coincidental.
Is she the person the Forgotten Man was trying to save? Probably not. Especially with two much more likely candidates already on the table. But Iβm putting her here just in case some extra twisty twist disqualifies the other two for some reason.
Dess is definitely the prime suspect as far as Iβm concerned. Thereβs more meat there than anywhere else. In hindsight most Papyrus knight theories themselves feel like people subconsciously picking up on the unexpectedly large number of Papyrus and Dess connections but coming to the wrong conclusion about it.
What it all means is harder to sus out, though. These two characters technically arenβt even characters in deltarune yet, after all. Theyβre just kind ofβ¦ haunting the narrative in tandem right now.
A man who wants to be forgotten vs a girl who insists you canβt forget.
Papyrus is a character in Undertale, though, so before I come to any actual conclusion, let me derail this entire discussion for a character analysis essay that may or may not be related to anything I was saying beforehand.
CASE 4: Undertale and Deltarune
Personally, Iβve always found it strange that the common fandom consensus is that sans is aware of the metanarrative and Papyrus isnβt when sans and Papyrus live together, Papyrusβs other best friend is Resets Georg, and Papyrus exclusively fights god (Toby) on the regular.
Like itβs true that Papyrusβs association with these concepts is wholly within the realm of speculation, but I also think itβs strange to assume there are no inferences to made just because the plot doesnβt spell out his involvement.
That being said, Papyrusβs involvement is hard to pin down for a reason. He is fucking with us to a certain degree. Heβs blatantly lying about not knowing what a laboratory is, for instance, but he also seems genuinely confused when he starts talking to Undyne about spiders.
Iβm choosing to believe that this is an intentional bit on Papyrusβs part. He knows he has random episodes of psychosis and amnesia, but doesnβt want to worry the people around him, so he just makes a series of bits where he pretends to forget things so that itβs less obvious when he has genuine episodes.
I actually think the most interesting bit of contrast between sans and Papyrus is that sans is like. desperate to tell anyone his secrets, to the point where heβll hand you the keys to a massive bombshell of a lore drop the minute you give any indication that youβd understand, whereas Papyrus will usually just double down until you drop the subject if you catch him red-handed in a lie.
This also strikes me as a really funny example of survivorship bias β the only reason the undertale fandom sees sans as this penultimate keeper of secrets is because heβs the only character in undertale who instantly tells you everything he knows the minute youβre left alone with him.
Papyrus doesnβt know less than sans, heβs simply better at keeping secrets than him. If he wasnβt, we wouldnβt have needed to talk to sans to find out Papyrus was friends with Flowey in the first place.
The issue with doing any meaningful character analysis of Papyrus is that heβs too good at keeping secrets. sans has extremely obvious tells. He acts like a jokester whose words you shouldnβt take too seriously, but he drops the act the minute he has something important to say.
Papyrus, on the other hand, is in Papyrus mode no matter what. He never even drops his font the way sans does. Not even during the lost soul segment. The only way to tell how much heβs telling the truth is through the reactions of other characters, and the majority of your interactions with him are exclusively between the two of you. He never, ever drops his guard and thatβs exactly what makes him interesting and infuriating to try to analyze. Anything but the most superficial analysis of him is like trying to catch smoke.
How to kill a time traveler is just about the only theory post Iβve seen run with the idea that Papyrus is just as meta aware as sans is, but it does so in a way I think ignores a lot of the juiciest concepts here.
Thereβs also uh. A really big hole in it?
In How to Kill a Time Traveler, one of the biggest points sock muppet tries to make is that Papyrus is playing the fool to coax information out of the people resetting, which he allegedly feeds back to sans, but Flowey blatantly gives himself away according to the videos own observation, so like. Why doesnβt sans know flowey can reset the timeline?
In the genocide route he blames you for every reset. The reason the βyouβd be dead where you standβ monologue happens even when you havenβt done a neutral route is because sans canβt differentiate between floweyβs resets and yours. He thinks you did everything on floweyβs saves. Which begs the question: If Papyrus knows that flowey has been doing resets, why hasnβt he told sans?
If you really wanted to defend this point, you could argue that flowey simply learned his lesson and reset, creating a timeline where he doesnβt tell Papyrus, but flowey doesn't know that anyone else know it's Papyrus's favorite food, so that can't be it either.
Itβs honestly one of the reasons I think Papyrus kinda has to know about saves. Even if he isnβt from the deltarune timeline and sans told him nothing, thereβs no way heβs never caught a ten year old he spends all his time with hiding something so big from him.
Sock Muppet argues that Flowey was manipulating Papyrus into instigating the true ending in Writing on the Wall, and even without that I think a lot of people are under the impression that he was naively tricked into helping, but letβs take stock here:
Who set you up with Undyne, who would have otherwise refused to befriend you? Papyrus.
Who forced Alphys, an infamous shut in, to leave the house long enough for you to sneak into the true lab? Papyrus.
Who invited everyone to new home to get got by Flowey in the first place? Papyrus.
So I gotta ask. Which do you think is more likely?
A child whose defining character trait is being alienated from peopleβs feelings understanding the concept of gay yearning well enough to know that he needed Undyne to keep Alphys distracted in order to instigate a series of events that would indirectly let him regain his body.
Or a guy who canonically convinces his homicidal friend to befriend you by trapping you alone in a room togetherβ¦doing that twice.
If the Pacifist route can be said to have a mastermind, it is almost definitely Papyrus. He just doesnβt scan as such to the audience because heβs less the stereotypical, moustache twirling Man Behind The Slaughter, and more the DM of a local game shop who is trying his damnedest to convince the partyβs local murderhobo to stop killing every npc he meets.
Simply put, rather than sans and Papyrus being in cahoots with each other, I think Gaster, sans, and Papyrus are simply coping with the metanarrative like those bitches from Pathologic.
Theyβre aware of each otherβs existence, and they arenβt necessarily hostile, but each has a radically different philosophy on how to deal with the topic at hand that leaves them diametrically opposed, which ultimately causes them to tackle the subject alone. The plot of undertale (and deltarune) consists of the player deciding which characterβs rhetoric regarding the player is true.
sans assumes the worst of you, and the genocide route consists of you proving him right. The ways this is true and how he reacts to being disproven in other routes has already been talked to death though, so letβs move on to Papyrus and Gaster.
Papyrusβs philosophy is a radical belief in the playerβs ability to do good. With all the talk about Noelle being a character skilled at finding video game secrets who is part of a secret route, then I think we may be underestimating the significance of Papyrus being a roleplayer who lives in a roleplay game. Papyrus acts like he doesnβt know what a human is or what the sun is for the same reason an actor at a renaissance fair pretends not to know what a cell phone is. Heβs a professional. Of course he wouldnβt break keyfabe.
I think a majority of Papyrusβs actions are informed by the monologue Flowey makes near the end of the genocide route:
βAs time repeated, people proved themselves predictable.β βWhat would a person say if I gave them this?β βWhat would they think if I said this to them?β βOnce you know the answer, thatβs it.β βThatβs all they are.β
Imagine, if you will, if a skeleton heard that kind of rhetoric. Imagine if he then manufactured more npc dialogue than the gameβs narrator to forestall that end point for as long as humanly possible.
In 1001 Nights, the framing device is Scheherazade telling a story to her captor every night, and then ending the story on a cliffhanger so that he has to wait another day to behead her.
In a lot of extra materials, Papyrus is noticeably less talkative than in Undertale. Not a total recluse by any metric, but he doesnβt seem to speak much unless spoken to first. In Undertale, Papyrus mentions being a big fan of Mettaton, but when heβs actively in Papyrusβs house during the alarm clock christmas party, Papyrus doesnβt speak to him at all.
Deltarune itself has made a progressively big deal about how Krisβs closest friends have never really seen them as they are because of the playerβs influence, and I wouldnβt be surprised if Papyrus became another avenue for exploring a similar conceptβ how his persona is influenced by our presence, and how little of his personality it likely captures, even if heβs never lying, per say.
In programming spaces, βspaghetti codeβ is slang for just about any badly optimized, hard to read code. Undertale, as a starter project, is full of spaghetti. Every NPC interaction in the game is in one switch statement. By reading Papyrusβs NPC dialogue, we are consuming his spaghetti. He will tell you 1001 stories in every room you go to because thatβs what will keep him alive to you.
In much the same way sans weaponizes boss mechanics to prevent us from progressing, and Gerson uses shop mechanics to prevent us from killing him, Papyrus uses flavortext as a means of influencing players towards his goals. He prevents the player from succumbing to boredom and killing everyone by actively going out of his way to make the pacifist option the most interesting choice.
Even if you, like Flowey, are only here to mine the game for more flavortext, youβll naturally end up doing true pacifist anyway, because thatβs where a majority of the flavortext is, for reasons almost exclusive to Papyrus.
Ironically I think the most obvious examples of Papyrus weaponizing boredom against you are in violent routes. If he meaningfully reacts to his friends deaths, it will make killing them interesting and further incentivize you to do it, so he intentionally feigns ignorance until he can guilt trip you into undoing it at the very end.
A lot of people think Papyrus is more powerful than he lets on, and I agree, but I think one of the reasons that something like disbelief Papyrus never happens in canon is because putting up a meaningful fight would give the player a meaningful objective to overcome, incentivizing them to kill him even more. He instead frames sparing him as an accomplishment in the hopes that it incentivizes you to stop killing.
While sans copes with entropy with a sense of nihilism, Papyrus gives his life meaning by being an arbiter of player choice. His choices donβt matter, but yours do, which means that he can give his actions meaning by influencing your decisions. His purpose isnβt to make decisions, but to make options. He has a plan for where he wants you to go, but he also realizes youβll just reset afterwards if you donβt gain a sense of self-actulization from it, so he makes uh. Suggestions.
As an aside, Iβd argue that this specific angle of Papyrusβs character makes him haunt the narrative in chapter 4 to a surprising degree. A lot of people were kind of agog at how their favorite characters from Undertale were much shittier people in Deltarune, but theyβre honestly just as self-interested in Undertale. Toriel losing track of you after getting drunk is actually pretty mild compared to abandoning you in a town you donβt know with monsters that might try to kill you. The latter just scans better because another character instantly picks up the slack.
Kris basically spends the entirety of chapter 4 begging any adult in their life to do what Papyrus does within minutes of meeting you in Undertale. The tone of chapter 4, where the world is at stake and nobody is on your side, would not work if Papyrus was in the game before this point, because he would never have left Kris in this position, no matter the consequences.
The tl;dr of all this is that I think Papyrus is a solid representative of Undertaleβs game design ethos. Heβs at the epicenter of most player decisions in a game centered around player choice. His boss theme is literally used in the game's trailer. Itβs one of the reasons him being the forgotten man intuitively makes the sense to me. That a version of Papyrus, stripped of memory and individuality, would devolve into nothing more than a series of βyesβs and βnoβs. Itβs what his role in Undertale already was, so it makes sense that he would be a metaphysical representation of the player choice thatβs been taken away from us in Deltarune.
If Papyrus is a flexible DM who βyes,andβs off of the playerβs decisions (even to the campaignβs detriment), then Gaster, as Deltaruneβs DM, is one of those guys who watched a bunch of episodes of Critical Role and then held his friends at gunpoint until they acted out the novel he wrote. Absolutely dogshit DM who will railroad the party just to make sure that he gets to do the cool set pieces he came up with: the overwrought lore bible of βprophecyβ.
If Undertale is a game deconstructing player choice, then Iβd argue that Deltarune is a game deconstructing developer choice. If Undertale uses the existence of Frisk and Chara to analyze why players make the decisions they do, then Iβd argue that Papyrus and Gaster exist to analyze why developers make the decisions they do.
Itβs why Deltarune is filled with games within games, both literally in chapter 3 and metaphorically through the creation of dark fountains, which is to say nothing on the existence of chapters in the first place. Through the act of playing them, the game wants you to better understand the characters making them. It wants you to ask why these decisions were made in the first place.
Why would the developers give you the option to fight if acting opens up more engaging options?
Why would the developers give you the option to recruit enemies if the changes are only superficial?
Why would the developers add a bunch of secrets that are roundabout and difficult to get?
If thereβs a single objective best choice, then why add any others?
Why would they let you make a machine to thrash your own ass?
While Toby definitely errs on the side of player choice, he does add nuances to the discussion. The weird route is nothing if not an admission that the player isnβt always right, that guard rails should be set to prevent people from acting in bad faith before they tear the whole campaign apart.
Another detail that airs on the side of this authorship interpretation is the name WD Gaster itself. In English, two initials and a surname is a common format for pen name: RL Stine, KA Applegate, JRR Tolkien, ect.
Itβs not a theory I have a lot of evidence for, but I actually think WD Gaster is supposed to be an alias. In publishing, itβs common for a pen name to be used by a team of writers rather than a single author, especially for a book series. In the same vein, I think WD Gaster is supposed to be the pen name of whoever the acting royal scientist happens to be.
Throughout most of Undertale, itβs established that a lot of monster culture is holdovers from the war that monsters just. Never got out of the practice of doing. Likewise I think this alias was likely a tactic from the war days to prevent humans from tracking down the royal scientist that just. Never went away.
The biggest rebuttal to this is Alphys still being called Alphys, but her not going by an alias makes sense when you consider she made Mettaton before becoming the royal scientist, and didnβt publish most of her work as the royal scientist to the public to begin with. Even with the exceptionsβ¦ the catβs out of the bag already. The undergroundβs one celebrity is telling everyone your name. Not much point pretending itβs a secret. Most of the monsters don't even know you're human, so they don't put much stock in keeping it, either.
I actually think this is on of the things that makes her an interesting foil to Gaster. The man currently known as Gaster presumably buried himself so deeply into his work that everyone forgot his original name, while Alphys became so famous that her work as the royal scientist was no longer anonymous.
As for Gasterβs actual identity, it's undertale!papyrus. He's totally undertale papyrus. Just trust me bro.
CASE 5: Torrent
Okay. So. Deltarune. Itβs the name of the game. Let's break it down.
First word:
Delta
noun delΒ·βta Λdel-tΙΒ 1: the 4th letter of the Greek alphabet see Alphabet Table 2: an area of low, flat land, sometimes shaped like a triangle, where a river divides into several smaller rivers before flowing into the sea 3: mathematics : an increment of a variable βsymbol Ξ
A lot of people have been talking about the greek letter connotations, but, given the constant allusions to water by npcs, I think it's more likely "delta" refers to a place where bodies of water meet.
This seems relevant in that, well, we have Dark Fountains, which are certainly bodies of rushing water.
Then it hit me. A rush of water is called a torrent. By opening up a dark fountain, you are opening up a torrent.
For those who donβt know, a torrenting program is and was a common form of piracy infamous for giving people viruses back in the day. The way it works is that youβd obtain a seed, which basically a piece of a file, and then use a torrenting program with a connection to the internet to find the other seeds, which would get you the other pieces of the file you were missing. One might even call it a way to reassemble pieces of something scattered across time and space.
And. Well.
Seed noun siΒ·βd 1: a small, round or oval object produced by a plant and from which, when it is planted, a new plant can grow
An egg from a tree counts as a seed.
The forgotten manβs eggs are literally seeds found in a torrent. Thatβs why he says βThere were some issuesβ if you collect any of the eggs. Gaster canβt download the torrent without the seed. The roaring knight is seeding a torrent.
This actually puts together a lot of puzzle pieces with Dess, considering a very common piracy stereotype of the mid-2000s was teenagers giving the family computer a billion viruses on a torrenting program called limewire
There's already a billion posts about deltarune gaster being associated with green, and I think it's very likely that the sound test room from undertale was simply a fake "album" that Gaster put a piece of himself into and tricked dess into torrenting. The "device" is just dess's now virus riddled computer
This would also explain why the internet is out in hometown, and why you canβt make phone calls in the dark world. Gaster is using up all the bandwidth. In ye olde days before wifi was an accessible thing. People used to have to use the internet through their phone lines. This famously made a horrible screeching noise when it started, and also made it impossible to use the phone while you were online.
As an aside this also informs a lot of Spamtonβs deal. His writing quirk is that his speech is formatted in broken wikitext. The double brackets are supposed to be replaced with a link to a website containing information on whatever heβs saying, but the website doesnβt work anymore. Itβs also probably why βMikeβ stopped calling him. The signal was suddenly occupied by Gaster.
If a delta is a place where bodies of water meet, and any form of writing with a secret meaning could be said to be runes, then a torrenting program is, in fact, a delta rune. Every time you download more of "Deltarune" through chapter updates, you are downloading more of Gaster.
As an aside, thereβs been something bothering my autistic ass since 2016. See, Toby Fox is a guy obsessed with coming up with double entendres names for all of his characters. βAsrielβ being a mix of Toriel and Asgore, while also being the name of an angel. Undine being the name of a mythical creature, but also sounding like the word Undying. Sans being a reference to comic sans, while also being a character who has been displaced, and who is most relevant when he experiences loss.
Which begs the question: what the hell does Papyrus have to do with Papyrus?
Which is when it occurred to me. The dark fountains are constantly written to be evocative of ink. Papyrus⦠is another word for Paper. In a game where you are already overwriting something. And where a prominent theme about characters being used up. And he hasn't been seen in five chapters.
CASE 6: Ink and Paper
So finally, let's talk about color spaces.
To simplify a lot of technical shit, color spaces come in two modes: CMYK and RGB.
They're named after the colors in them (see chart).
CYMK is designed to add color to a white sheet of paper. Through this framework, you could say they draw by adding darkness to light.
RGB is designed to add color to a black computer screen. Through this framework, you could say they draw by adding light to darkness.
As you can see, combining each letter with one from the opposite color space combines to make black in a CMYK color space, or white in an RGB color space.
This is also why Kris needs the soul to seal the fountain: Cyan and Red combine to make white.
Susie then furthers this pattern with the green soul. Magenta and Green make white, and Gerson calls her "the white pen of hope" during his secret boss battle. Not to mention her development of green healing magic over the course of the plot. Green denotes something Susie can interact with.
Which leaves Noelleβs yellow as the only part of the pattern yet to be completed. She still needs to interact with someone with blue soul mechanics.
There's even the same shade of blue in the flowers on the countdown...
In conclusion, I think Papyrus might be relevant to the plot of Deltarune.
