Egg Route (Deltarune Theory Effortpost)
So the forgotten man, the semi-official name for the guy who hides behind trees and gives you eggs, is given some pretty interesting context regarding our playable character, Kris. This implies he (the forgotten man) is tied to some repressed trauma (most pronounced in the art therapy room of chapter 4), possibly violent in some nature (as alluded to by a line by the holder of the shadow mantle as well as one of the fellow patients in said art therapy room). While I'll only bring up the specifics here briefly, there's still the ultimate question of what this is all leading towards?
Well, three interesting facts could hint that the forgotten man is key to another alternative route, like the weird route, but in a (possibly?) more positive direction than grooming Noelle into a cryomantic death machine.
As noted in the above image, you don't get the "Chapter X END" achievements if you get the respective eggs of those chapters. Its even required if you want to do a run where you don't get any achivements from chapters 1-4 (promting special dialouge from the Voice). This is odd since said voice never brings up the weird route in a similar way, despite its effects on the plot being more obvious so far.
During chapter 2's weird route, you just cannot get to the egg room for the chapter at all. Which is strange unless the eggs are for their own route or something. Similarly (Edit: at least before 1.0.4, where this isn't the case), if you finish the sword route (which references the weird route) before getting the tripp ticket, you're locked out of the egg room for that chapter (granted, if you get the egg by the time you start board 3 this is a non-issue).
In speaking of chapter 3's sword route, if board 2 is meant to be at least partly taken as a hint towards the weird route (though it might not be its only purpose, as I theorised elsewhere), then there's an obvious parallel to be made with the schedule that the forgotten man gives (which hints at the locations of the other egg rooms of chapters 1, 2, 4, and 5).
Now, what this route entails, I have no idea. With the eggs being deemed "not too important, not too unimportant" and completely lacking any of the interactions we can have with them in chapter 4 that we did in chapters 1 and 2, I suspect the eggs themselves serve more of a counter for how many of the forgotten man rooms you've completed.
However, when talking to Malius in chapter 4, they reveal they have been trying their hand at breadmaking but haven't been very successful due to gluten intolerance, hindering their progress towards new recipes. Since eggs can be used to make bread, i could see us using these 5 eggs to make a cake or some shit for everyone to eat and then start tripping on kris's truamatic memeory lane. More of an out there idea that i'm not commited to.
Now for the general plot beats of the egg route. For one, we are going to discover the root cause of Kris's trauma that they are repressing (either involving Dess and what happened to her, Gaster, Kris's pre-adoption past, or a combination of the three), and we help Kris overcome that trauma. With Noelle likely making her second dark world appearance in chapter 5 (where we will get our last egg), i can also see a scene where we help Noelle overcome her truama.
A very likely consequence of this is Kris coming clean with whatever scheme they've been cooking up to this point, especially if the aforementioned repressed trauma has some connection to Dess and why Kris is working with the knight. At this point, Susie will be aware of Dess's fate and how this ties to Kris working with the knight to bring about the roaring. Whether the knight is Carol and wants to bring her daughter back, or the Knight is Dess and is forced to bring about the roaring for one reason or another, Susie is aware that the knight is more than just some bad guy who wants to bring about Armageddon.
Susie (and probably Noelle) will start crashing about Kris working with the knight (especially if Kris Slash theory is true and you did the sword route by this point), but everyobdy will calm down and the fun gang (and noelle) will have the shared goal of saving Dess or something and will probably have a vague awareness of there being a puppetmaster behind the knight's strings.
At the end of chapter 5, if you did the egg route, Gaster will just crash out on you for getting all 5 eggs or something, idk.
