What does the Glass in the Light World Actually Do? 

non tts voice jumpscare

I think that the Glass shows a world in which Kris never existed, like what Goner kid says in Undertale. The first one, seeing through your hand, is self explanatory because it's a literal representation of not existing. The second one, Susie acting coldly, is how she would be acting if the events of Deltarune up to this point never took place; Susie stopped acting so coldly because of the events of Chapter 1.

If the glass represents a lie that the person looking through it means, perhaps it represents Kris’s insecurity that Susie doesn’t actually like them, but the player, and that if they were themselves she may not like who they really are

Since the castle town dark world is in the supply closet, it could be inferred that Kris just never went into the supply closet before, so they don’t have any memory of what it looks like. It’s implied Kris has been in the unused classroom and computer labs before the dark world stuff, so they would have memories to see through the dark crystal(s)

In my opinion, the glass is showing Kris's insecurities. In the first chapter, because they're being controlled by us, them seeing through their hand could be seen as some sort of "out of body experience". The one in chapter two could be because now that Kris has a friend (Toriel implies that they don't have many friends) they are worried about Susie not wanting to be friends anymore, thus the cold glare. Edit: After thinking, the Chapter 1 glass is probably more so due to Kris being a bit of an introvert, and not sticking out much. Therefore, their hand being invisible could be about how they feel invisible, or that they don't matter.

I always thought the glass showed a world where Kris doesn't exist hence why the glass lets kris see through their hand, and shows a more hostile susie; of course she would be mad, she never met Kris, after all. And Kris seeing through their hand makes sense if this is the case too

It could also just show small fears of the person holding it. Kris fearing losing their sense of self and the friendship they have with Susie could be why the glass has showed them those images. As for Castle Town, we don't actually know where that fountain actually was opened, if it was ever opened at all. Its fountain must be a special one since it's the only one that can keep all darkners "alive".

I feel like the mirror just shows the other side of things. A world without Kris, a Susie that you never made friends with, the light world as a counterpart of the dark world... kinda like the other side of the coin if you will.

I feel like you're one of the only deltarune youtuber who actually uses genuine reasoning and legit facts to explain theories and stuff. keep up the good work!

Another great theory that I saw was that the crystals were "dead hope". An image of the users hopes and dreams being shattered. Use it in the dark worlds, and it shows the light world "shattering" Kris's hope of having fun adventures in the dark world. Use it by yourself and it shows yourself gone, forgotten about, and living in a world where everything functions fine, but you don't exist. Shattering Kris's hope of being known and themselves. Use it with Susie and it shows her glaring at you, hating you. Shattering Kris's hope of ever being her friend. (Theory is by @WeaselWeaselW)

I have a theory that the glass is "mirroring" future events. For instance, Susie being mad at Kris could be a mirror of something to come, possibly in a much later chapter when she finds out they've been opening dark fountains, or just some other conflict between the two. As for Kris' hand disappearing, it could signify the end of the game and Kris either dying, our connection to them disappearing, or something else entirely. I suspect that the glass goes in reverse order; Chapter 1 being foreshadowing for chapter 7, ch.2 for ch 6, and so on.

One possibility I thought of is that they essentially show inversion of light and dark. When used in the dark world, Kris holds it up to the surroundings and it shows the light world. When used in the light world, Kris holds it up to themself and Susie and sees the darkness inside themself and Susie. It would fit the whole duality theme Deltarune has going on.

I like the thought that the glass piece in the real world is reflecting how the characters feel about themselves, and the shadow crystal reflects what is actually "real." Kris isn't so much of a ghost, more that they feel that they actually aren't "there" while Susie sees herself still as a bully. The Dark World allows them to be who they want to be: Kris has something motivating them and Susie can be something more than just the villain/a bully. So, the shadow crystal reflects what the reality is: They are still inside a room filled with toys, or in a computer lab. And the glass piece reflects their lingering insecurities of "who" they are. The glass pieces are showing different perceptions opposite of where they are used. The real world shows internal realities, while the Dark World shows external realities. The reason why the shadow crystal doesn't work in Castle Town... is because Castle Town isn't inside the janitor's closet. The janitor's closet is the area preceding Castle Town, while Castle Town itself is its own special area connecting the closet to the abandoned classroom (and certainly the computer lab, too). Hence why darkners can live there without turning to stone.

The one frame around 3:27 says “No arms are connected”, referencing a message that pops up in Undertale when you disconnect your controller

Maybe the glass shows your fears? Could be that Kris fears not being known by anybody, and Kris also fears Susie only pretending to like them

This is super interesting! The glass and crystal showing things as they were makes a lot of thematic sense, too-many characters throughout the game are constantly talking about the past and how things used to be, usually in a nostalgic manner. Undertale had a HUGE connection to nostalgia as a concept, from it being reflected in the theme of characters moving on, to how the game’s twists and “false” premise are reliant on the player’s knowledge of classic RPG tropes. I think you’re really onto something here. Whatever the meaning of the glass reflects (haha) it’s probably gonna be really important.

During the glitch effect at 0:40 text pops up on screen which reads "WOWIE", then "AMAZING", and then text in wingdings which I have translated to "THE FLAMES HAVE GONE OUT YOU QUEST IN VAIN" , then "No head is connected"

That's a very interesting theory, but your first theory can be true as well. Even if Kris and Susie are great friends, there can still be some doubt. Kris can have a mindset of "what if she is faking being my friend ?" because even if they value Susie, the fact that they never had friends before can cause them to have self-doubt and make them think no one would truly want to be their friend. So the Glass showing Susie looking coldly at them could be showing "the lie" of Kris have the doubt that Susie truly cares for them, despite wanting to believe she cares.

About the point that starts at 4:22 I'm no expert in mental health, but I've seen plenty of people tell themselves that even their best friends don't really like them, even when that's clearly not true. So I guess we shouldn't be dismissing the idea that Kris deep down still fears that Susie still wants to be mean to them. I hope that made sense lol

4:57 YOU DID NOT NEED TO SHOE BERDLY WHEN YOU SAID “unimportant”

I've had a theory for a while that the Glass are representative of Kris's psyche, particularly the pieces clouded by things like trauma, depression, and self-loathing. The one where their hand disappears in front of their face is like the part of them that tells themselves "Everything would be better off if you disappeared." And the one where Susie stares coldly at Kris is the part that says that Susie is only pretending to tolerate Kris and actually hates them. (While this may be obviously untrue, someone who is hurting in this way may not be able to stop themselves from these feelings.) I also think this may connect to the Dark-colored blogposts on Noelle's blog, the ones that are black and gray instead of pink and Christmas themed. They all seem strange and surreal or have connections to some strange stuff, and the one about Susie and Kris ("Th3_n3w3st_g1rl_g1rl") directly contradicts a lot of established facts from the game, to the point of seeming like some kind of twisted version of the morning of chapter 2.

Saw some other people saying, and I agree, the crystal may be showing the fears and insecurities of the holder, in this case, kris. So, it is still showing the 'truth', but not the objetivity of whats happening in the light world, just the truth of what's going on in Kris' head. They fear they are a nobody, they fear Susie will ever look at them in a cold way. I know Susie just threatened them a few days prior, but I think there's a difference: before, she was intimidating, scary, she put on a perform of disliking everyone and being 'mean' (tho there's some indication Kris never took all of that serious); now, they are friends, Kris truly loves Susie and would hate to lose her. When they see Susie looking 'in a cold way' at them, the implication is not that Susie is looking as she did before, in a intimidating way, but a disappointed, angry in a 'I am your friend and I can't believe you did that' way. In my opinion, it shows Kris fear of maybe doing something that's disappoints Susie and makes them lose her. So, the crystal in the dark world: since the worlds seem to be close related to the lightners, always show the truth about where materially it comes from In the light world: show the truth about the fears of the lightner holding it

At the start, i was scared that thou hadst revealed thy voice. Thank god thou hadstn't

6:23 since the player chooses to look through and, the text says that we see through *our* own hand it could be showing us that the player used to not be there

I really like WeaselWeaselW's interpretation of shadow crystals being "shattered dreams". They show what the dark worlds truly are instead of their dreamlike fantastical variants, that Kris may fear losing themselves completely and fears losing the friendship they have with Susie now. They also come from characters that can be connected to that theme, especially Spamton is someone defined by shattered dreams. It would even explain why the item is shown as a "crystal" and "glass", being a literal shard. Also as a sidenote I'd love to see a video on the creepy ocean/water connections within Deltarune and Undertale, that has intrigued me since forever and perhaps the ending in the video alludes to that. Either way, keep it up, your videos always lighten up my evening!

I love the theories that are quite outlandish but also very well could be true. Like, imagine if HalfBread just here and now predicted a huge reveal from chapter 5? Out of seemingly almost kinda random.

I like the theory that it shows you a world in which everything is the same, except you don't exist. Kris sees through their hand because... well duh. The dark worlds don't exist, because... well, perhaps Kris is the Knight. Perhaps Mayor Holiday is the Knight, and she would have no reason to be in a world without Kris, because Dess would never have gone missing. Susie glares coldly because Kris she never would have had that dark world adventure to bring her out of her shell.

That very last point is very interesting to me. We know Kris existed in hometown before the events of the game, but the history of their Soul is less certain. If we somehow replace or override Kris’s Soul at the start of Chapter 1, it’s possible that the Shadow Crystal can’t display what state Kris was in before that point

What if the world in Deltarune you play in gets created when you first establish a link with Kris, and that's why the timer for your savefile starts at 0:00? Starting the game at a later chapter just means the world was created at THAT point, and the previous chapters are "Last-Thursday'ed" into occurring.

loved the short vid! the idea of the crystals/glass showing the past is intriguing, but I'm all for it showing the future as well, or just showing different timelines in general. future just currently seems more plausible as then Kris and Castletown coming from nowhere isn't a problem, but future implies pretty interesting things. can't wait for part 2.

Been binging your videos as of late. I didn’t think I would’ve ever been much a fan of the TTS, but gosh, it just works so damn well. Love it

maybe the abilities of glass and shadow crystals are one and the same: to see the future and/or past?

The past angle is interesting, but by that logic it could also show the future instead. Dark worlds changing back into the classroom and the lab respectively, some future events we aren't aware of yet damaging Susie's opinion of Kris, and Kris' death (or disappearance?). That makes more sense then Kris somehow not existing before to me , and also better explains why nothing happens in castle town: in the future it simply won't change much (it should show the closet if it's the past).

I love how you explore different theories in your videos!

yaaaayy you're backk! love your theories and video styles. keep it up!

Adding that little glitch effect when the TTS screws up is a really cool detail!

I actually have a theory for the”for a brief moment you saw Susie glaring at you” I think this actually might be referring to a possible different chapter while in Snowgrave Route, because who knows, maybe you freeze like lancer or Ralsei in front of Susie. Or maybe the chapter 3+ bosses will show Susie who we REALLY are and Susie will seem less trusting in us, almost like the chapter 1 state, where you can barely see emotions in Susie. Let me know if you have a similar theory!

Neat analysis video! Thanks for uploading!

dude i found you recently and love ur content fr i been binge watching it keep it up

For me, the glass in the lw is shows the person holding it what they fear, Kris fears being functionally fake and fears Susie stopping being their firend, they don't fear her going back to a bully. I guess you could also apply that to the dw and say Kris fears the fantasy ending (although maybe "sadness" works better in this context instead of fear?), but that leaves some questions for what is going on with Castle Town

babe wake up new halfbreadchaos video just dropped

Every time you upload i get really happy, you have me hooked on your videos

Bro these videos bring me back to the good old days of theory crafting undertale and deltarune every single time

Heck yeah another HBC video to fuel my brainrot!!

I spent multiple minutes trying to see the text that popped up at 3:27… it’s just “no arms are connected”.

another nice video from Breadchaos, am always happy when we get a vid

I like the new classroom area in the video, keep up the good work!

i love it when you post videos it makes me cheerful

My theory is that the glass allows us to see the world through the eyes of us, the player. In the overworld, we don't see Kris, because they're a "puppet" of the player, thus they don't really have an identity on their own; and when looking at Susie, we get a cold glare because she doesn't know us. And in the underworld, it shows how the overworld would've been if the player hadn't interfered at all , i.e. a normal classroom and a normal computer lab; It is through our actions that we shape the events of the world, so if we never played the game in the first place, everything would be normal. The only thing bothering me about this theory is the implications of the existance of the first savefile present when we start the game for the first time, though I'd love to hear your two cents on it.

You know how things in the Light World are boring and mundane, but they become awesome and fantastical in the Dark World? I don't believe the shard of Glass has magical powers in the Light World. Imagine for a moment that you're holding a tiny mirror. It reflects the scenery behid you, which probably looks a whole like the scenery in front of you. As you hold it in just the right way it may seem, for just a brief moment, that you're looking through your hand. When you stop looking at Susie with the glass, she's "smiling and making a rude gesture". I don't think this is spontanious behavior, it looks like she's teasing Kris. She saw her dork of a friend looking at her face with a tiny mirror, tried to scare them with a cold glare, then she teased them. Notably, neither of those events are followed by a "... but, it must've just been your imagination". Kris knows exactly what the Glass is doing, and has no reason to excuse it.

Another very cool theory, thanks for sharing!

I like the idea that it shows you either your darkest thoughts (Kris’s either fear of Susie or the theory of them being dead) in the light world or the truth in the dark world since it’s already an extension of what the glass would do on a larger scale.

I think the glass looking through your hand is supposed to represent Kris’ ability to pull out their soul. Or maybe it shows the true soul of a person. Kris being invisible everywhere but the soul heart we play. And susie’s “rudeness” is actually just her soul being gaurded like susie is at the beginning of the game.

the idea that kris didn't exist before chapter 1 makes the concept of a chapter 0 very interesting

Much love as always HBC your a great mind

I just came to your channel yesterday hoping for another video. lone behold, it came

If we run under the logic that the glass/shadow crystal show the past, then I think that Kris being able to see through their hand in chapter 1 can be pretty simply explained. From a meta game perspective, there was no Kris before chapter 1. In fact, nothing existed before chapter 1, as anything before chapter 1 implies that it's before we (the player) started the game up! But, I'm not so sure that this is the approach that Toby would take for this game... Interesting nonetheless! :)

3:50 oh god it scared me so hard lmao

Nice theory, good luck for the next video !

I think youve always asked the right questions chaos... the time is not as far away as we might fear, where more questions are to be asked, and more things to be learnt

I had exactly the same thoughts. But there is another version, the glass shows Kris's imagination. Their fears and "dark sides", while in a dark world they shows the "light side". Kris is definitely afraid of disappearing... They's also afraid that Susie will get mean at they again. We will definitely have more interactions in the future that will shed light on this glass theory.

0:47 HALFBREADCHAOS LORE CONFIRMED?!?(connected to the roaring?!?)

you are 1 step closer to reaching 100k subs!

Maybe the glass show what the person who have it is afraid of? Kris afraid of dissapearing and that Susie will be like before

I hope chapter 3 shows more stuff about how the shadow crystal or glass might work, especially when we're in Kris house.

1:35 yoo it's fullbreadchaos

"kris believes himself to be a nobody" *shows beardly through the reflection* Statement of the decade

woah next video is a big one? i can't wait to see it :D

AH WHAT IS THAT STRANGE VOICE

i am early, also i love your videos HBC :D

Best undertale/deltarune RU-vidr keep it up! I’d really like to see you make a video on how undertale is a game within undertales universe as revealed in the MTT news segment. And also maybe one about the room before the temmie one, but after gersons. The one with the floating white specs

i think the glass shard, when used in the light world, lets you see the "inside of a person". when used on kris you see through you arm because kris is empty, a puppet controlled by the player while susie's cold look could be explained by her clearly hurt and pessimistic soul, since our friendship obviously hasn't "cured" all her problems and trauma.

Good video

This is off topic, but how did you make your sprites?

HBC makes such great videos so often ❤️

Doesn’t hear tts. Clicks off immediately. Refuses to elaborate. Leaves.

I'm autistic and somehow your channel is becoming a special interest to me

I’ve heard a theory that when we take out the glass, Susie is simply giving Kris a weird look because they have no clue why they’re looking through glass for no reason Of course it doesn’t explain everything else about the glass

Honestly when looking at Susie with the crystal I thought it was just her being silly(like she would be doing that hand thing where a person has an expression, moves their hand over their face and changes to a different expression). Seeing how she acts in chapter 2, I wouldn't say this is out of character for her

6:17 If it shows you a day or so back, Castle Town was still there, since its dark fountain seemingly was open way before and never closed

Notification gang

bread 🍞👍

I just want to thank for using text to speech instead of just captions. It makes watching these videos so much easier and engaging

maybe, if the glass in the darkworld shows us the "truth", maybe in the lightworld it shows us the "lies", that could explain the cold expression of susie (just as she probably saw Kris before the card kingdom adventure)

2/10 Video, at 4:02 it's actually supposed to be "sole" instead of "soul", this ruined the video for me.

Got some voice actors, nice addition.

The start was a scarier jumpscars than all the fnaf jumpscards combined

0:40 for just a slight moment, you can see some wingdings which say "THE FLAMES HAVE GONE OUT YOU QUEST IN VAIN"

following what you said in the end, maybe its not what existed there before, but what the bearer knew about that place/person, it would also explain why there was nothing in castle town, kris simply did not know what was there before

0:40 spent a hot minute translating the wingdings hidden in the glitch it says "the flames have gone out you quest in vain"

This is a good theory! My personal interpretation was always just- Like everything in the light world, its just a normal object. If it’s a shard of glass - specifically, shards can refract light in weird ways which, when being held in the fingers, could easily make it look like a different color from your hand. As for Susie’s expression, just glancing briefly through the distorted image through glass could make the expression seem different. Or tbh it could be both, and in universe its just glass but meta narratively it’s a hint at the plot? Shrug. Either way, nice video as always, Halfbread!

yea, I can see Susie just smiling while giving you the middle finger.

3:28 i love how you used skies forever blue for the visualization

Just a cool thought I had, but what if these singular Shadow Crystals only let you see a glimpse into the past, and perhaps when enough are collected, you'll be able to form some 'Shadow Mirror' that'll allow you to do something cool, like maybe fully see into the past to finally find out who the Knight really is? Or maybe Ralsei's origins and how he knows so much about the Dark Worlds and the Roaring?

I think that A: It is talking about the player, we have only “existed” for one day, as far as we know. And B: in chapter one, we fall into castle town after the mysterious place in the closet, and since it seems to allow things from other dark worlds to exist fine, like Ralsei can in other dark worlds, maybe it was there before we were? Like ralsei seems to have been?

Haven't seen the entire video, or read most comments. With every explanation of what the glass shows in the different circumstances, I think it's not supposed to be some sort of "future sight" or a representation of Kris's insecurities, instead it seems like it shows... The past state of things; let me elaborate. For the worlds, it seems to show their counterpart (light world dark world), which aligns with how at first they appear (so first we have dark world > glass look into light world) until Kris seals the fountains. However, due to the interaction with the glass being focused on the characters in the light world, that kind of complicates my theory for obvious reasons, as we do not know if the glass in the light world can show its counterpart. However, how the characters look in the glass seems to support further my idea; Susie was cold and mean, but in the past, and Kris "not existing" could be a reflection of how before the whole adventure he was just that, "nobody", someone that was never seen as his brother, as a BIG SHO- AHEM, in any case, it seems to align somehow, but it's just random thoughts, and I don't think Toby intends for the glass to function that way, unless... We were chasing someone lost in the past. CHAPTER 3 DESS CONFIRMED!1!!1!!11?!?1?'1?1?1? Well, of course not, but if my theory was correct, then it would make sense that the glass allowed in any capacity to confirm once and for all what happened to her. And now that I finished the video, HalfBread comments the same thing as I did, yay.

Something about “staring coldly” can have very different meanings. On one hand it could be just a mad stare or a rude glare, but it could mean that it is an empty stare. Empty, no emotion, just a stare. This is what I originally thought when I first saw it in game.

Counter-argument to the point about Susie: our influence over Kris. Chapter 1: Kris has lost almost all agency to us, therefore they pretty much consider themself to not exist. Chapter 2: Most of Kris' positive interactions with Susie happened under our influence, thus they expect her to go back to hating them as soon as we're gone.

It really takes one video one singular random video to make me absolutely hiped about deltarune again even after 2 mounts of not wanting deltarune content. GOD DO I LOVE THIS GAME!

The "Shadow Crystal/Glass shows the past" has been my "best guess at" canon for a while now. While I disagree with most of Jaru"s theories, the idea that the Deltarune world has been in a timeloop for a very long time seems likely, though I admit that it's one of the more speculative ideas here. This gives a possibility that the SCs empowered and drove Jevil and Spamton crazy by showing them what they thought was the future but was in fact the past, thus creating a self fulfilling prophecy.
