Spoilers for Deltarune Chapter 5 under the read more (and also a comedic cutaway)
I KNEW IT!!!! I KNEW THE CODE WAS MORE THAN FOUR DIGITS!!!!
‘oHhH i WoNdEr WhAt ThE lAsT dIgIt Is’
‘OhHh SuSiE cAn’T rEmEmBeR fOuR nUmBeRs’
‘IgNoRe ThE cHuRcH dOoR sUsIe’S jUsT STUPID.’
WELL WHO’S LAUGHING NOW?!!!?!!
In all seriousness, I imagine if Susie got more than a glimpse in chapter 4, she’d be able to remember it easy. At first this looks like a jumble, but it only takes a sec to realize it’s a date.
The month and day Undertale was first releas— no, obviously not. For one, if this was meant to reference Chara, it’d be 201X, not 199X.
Here’s my theory. Well, more a hypothesis:
This is the date that someone went missing, and the date in the guitar is when December went missing.
It’s… a little hazy, but it’s the only through line we have. We know Deltarune takes place in the 2020s thanks to… I don’t remember but somewhen the year 202X is mentioned, which means that this disappearance took place a long, long time before the events of the game.
After all, if the guitar code is Dess’ disappearance, and Dess’ disappearance is what led to Asgore’s forced retirement, then….. I don’t know, I just finished Chapter 5.
Still, I think this hypothesis has merit, it’ll just take a ways longer for it to gain some ground.
I’m probably not even the first person to come up with this, tbh.
