History Fridge / Deltarune

* There's two implications about what's coming in Chapter 3. That it's Dark World will be [[TrappedInTVLand television themed]], and that we'll meet a character named "Mike". Taking them both together points to the joke of the title [[Literature/CharlieAndTheChocolateFactory Mike T.V.]]
* As one redditor pointed out, remember how the save file had Kris' name instead of the player's? If you decide to play Chapter 2 without loading Chapter 1 save data, it will play as if you made very specific decisions in Chapter 1, possibly indicating that those are the "canon" decisions that Kris would've made if they weren't controlled. For instance, Kris took the pacifist route, ''didn't'' meet the original Starwalker, ''didn't'' fight Jevil, ''did'' talk to Alphys after leaving the Dark World, ''didn't'' meet Onion, ''didn't'' talk to Sans...
* A few people pointed out that "Knock You Down!" sounds kind of like "Stronger Monsters". When compared to the other ArcVillain you've fought, Queen is effectively a "stronger monster."

** Not just that, while everyone else was updated to the new 32-bit sprites used in Deltarune, Sans is still identical to his 16-bit sprite from ''Undertale''. He wasn't just so lazy he didn't change outfits, he's so lazy he didn't even change ''[[LeaningOnTheFourthWall graphical styles]]''.

* Should the player keep attacking the Dummy during Ralsei's tutorial instead of following along, Ralsei will say that should the time comes, he's fine with Kris hitting him should they feel like it. Ignoring all the potential FridgeHorror that could come with this, Ralsei's relatively passive demeanor towards this makes sense if one considers that he's a healer, and any damage that can be done to him can negated with a simple spell.

* Spamton's shop is radically different from every other shop in the game, with his inventory being completely useless at best (the broken sword) to outright harmful to the party at worst (S. POISON). Even his two "useful" items are either stolen from Swatch(the B.SHOT Bowtie) or sold to you with an ulterior motive (the Keygen). But this makes perfect sense. Spamton lives in and sells his wares in a garbage dump. As in, ''it's literal garbage'' that nobody wants or has any use for, hence the location and terrible selection of items.

* There's an interesting parallel between Kris and Spamton's deal in the normal and Snowgrave routes. On the normal route, Kris follows all of Spamton's directions exactly, only for the salesman to reveal that he was just using them to achieve his dream and attempts to kill them and take their SOUL. In other words, Spamton double crosses Kris once he gets what he wants out of the agreement, because he wants more than what was originally offered. On the Snowgrave route, Spamton actively assists Kris in their slaughter by selling them the Thorn Ring, and Kris's actions directly lead to Spamton gaining access to the mansion's basement, allowing him to take the robot body for himself. Here, both sides get exactly what they want, and Spamton is willing to leave Kris alone after the fact... until Kris goes behind Spamton's back and attempts to seal the fountain, thus screwing Spamton out of his newfound power. Here, ''Kris'' is the one who double crosses the other party, and they do it in exactly the same way Spamton does in the normal route-- by trying to gain something more than what was originally offered (killing dozens of Darkners, ''and'' attempting to seal the fountain, which Spamton was not aware of in the original deal).
** This would also explain why Spamton is much more aggressive in his Snowgrave fight and gets genuinely angry at Kris during it-- he realized he had been double crossed and used, and Kris was about to screw him out of the power he had just achieved!

* Susie, mentions having bypassed a puzzle by simply walking over the spike blockade. It could be an OffscreenMomentOfAwesome for her. But consider that all the spike blockades you encounter are when Ralsei is in your party. Kris and Susie are both wearing thick shoes, but Ralsei is {{barefoot|CartoonAnimal}}. Kris might just be refusing to do the same for his benefit.

* The [[RunningGag usual]] "smells like [x]" gag for Berdly states that it "Smells like frozen chicken." However, Berdly uses ''[[BlowYouAway wind]]'' magic in the Dark World, not [[AnIcePerson ice,]] so this wouldn't make sense at first. However, consider who ''does'' use ice magic; Noelle. Noelle is [[BehindEveryGreatMan the real brains]] between Berdly and herself, since the former is only regarded as an InsufferableGenius by everyone else because he won against Noelle in a spelling bee and also studies with her.

* Why does "Attack of the Killer Queen" have snippets of "Smart Race," Berdly's theme, in it? Not only was Berdly serving as Queen's right-hand man for a significant part of the chapter, but also because she's puppeteering a mind-controlled Berdly to fight you!

* In the cutscene where Kris first encounters Spamton, he pops out of the dumpster introducing himself with a fanfare like he heard someone was there, yet his '!' emote and the way he turns around to face Kris suggests that he didn't actually see Kris until that point. While you could chalk this up to Spamton being his usual crazy self, remember that Spamton has a degree of MediumAwareness and knowledge of the player and SOUL as a result of his insanity. He didn't jump out because he sensed Kris approaching nearby, he sensed the ''the player's'' presence looking at him and his dumpster.

** It's important to note that Susie seems to have a LoveByAll reputation, at least inside the party; she's the only character whose tea heals everyone for at least 120 HP. Inversely, aside from [[TrueCompanions Susie]], who gains 120 HP from everyone else's teas, Ralsei heals the least, only healing [[ChildhoodFriend Kris and Noelle]] for 60 and 50 HP respectively; it makes sense that, while he's likable, he's also only known them for a day, while the Lightners have all known each other for upwards of a decade.

* Lancer rides a bike. A bicycle. He has a playing card motif. Bicycle. Playing cards. Bicycle is a popular brand of playing cards.

* Why is the K.Round at the end given a crown? Due to the fact that it's at the end of the checkerboard, so it got kinged.
** K.Round. Kround. Crowned.

** Inversely, they hate jelly donuts. The Hearts Donut heals them 20 HP out of combat, and in combat, it only heals 10. Susie, on the other hand, loves it, healing her 8 HP out of combat, and ''90'' in combat! This could be taken as foreshadowing that Kris hates the heart-shaped SOUL that's pulling them around.

* Following the ChessMotifs, Kris is clearly the Pawn, since, well, [[ExactlyWhatItSaysOnTheTin they're the player's pawn]]. But what are the characteristics of a Pawn? Once they [[TheStinger reach the end of the board]], they can be [[CreateYourOwnVillain promoted]] into many pieces — for example, a [[AmbiguouslyEvil Knight]] — and while still a pawn, [[YouCantFightFate the only way they can move]] is to [[VideoGameCrueltyPotential Pro]][[ArcWords ce]][[{{Gaslighting}} ed]] straight forward, unless they are moving to [[EarnYourBadEnding take another piece]] (in which case they move [[OffTheRails diagonally forward]] while capturing and lock themselves onto a new path). Also, the [[FirstEpisodeTwist first move]] of a chess game can only be [[EpilepticTrees one of two options]]: [[RedHerring the pawn]] or [[EvilAllAlong the knight]].
* If you try to interact with Spamton in the basement on the Weird Route, he says "IT'S NOT MY JOB TO BE SOME KIDS' [Extra Boss]!". By the time you reach this point, you've come too far and you can't stop the Weird Route. Spamton can't be an [[{{Superboss}} Extra Boss]] anymore; right now, he's the FinalBoss.

* In the Weird Route of Chapter 2, Spamton will criticize you for taking that route even though he's steering you towards it and sells you one of the items you need to do it. This makes sense when you look at Spamton NEO, who is held up by strings - Spamton is a puppet and ''has'' to act in the way he's required to. Given that this is Cyber World, based on computers, and it means Spamton can't defy his programming. He's been programmed to be a salesman, so he has to make Kris the sales pitch and has to sell him the item because that's his entire purpose. But he's not criticizing Kris, because Kris doesn't really have a choice either. He's criticizing ''the player,'' who ''did'' have a choice about whether or not to buy the item from him and pursue the Weird Route.
* When Susie has her moment of clarity pointing out just how.... ''wrong'' the Spamton sidequest is, she's especially unnerved with "the way he just.... broke." While this can be chalked up to Spamton turning into an inventory item being a case of UncertainDoom, Chapter 2 of the game establishes that monsters still turn into dust when they die like in Undertale. Given Kris is clearly the only human she knows, the idea of leaving behind anything besides dust, ''especially'' an unmoving, nonfunctioning corpse is probably a foreign concept to Susie.

* Deltarune was confirmed to have seven chapters. Each chapter is a day in-universe, and by far only 2 have been released, the second taking place the day right after the first. Toriel said that Asriel will be coming home for summer vacation in a week, in seven days. So ''Deltarune'' takes place the week before his visit, and just like in ''Undertale'', the climax of the game is related to Asriel's arrival. After all, Asriel has already being associated with the Delta Rune's Angel in the past.

** Not just that, while everyone else was updated to the new 32-bit sprites used in Deltarune, Sans is still identical to his 16-bit sprite from ''Undertale'', he wasn't just so lazy he didn't change outfit, he's so lazy he didn't even change ''[[LeaningOnTheFourthWall graphical styles]]''.

* Of the pre-existing characters from ''Undertale'', Sans is the only one not wearing a different outfit. It's lazy character design...for a character famous for being lazy.
