Alright! I’ve pieced together my views on Deltarune and its connections to Undertale, and I think I can present it now as a theory.

So the most important question concerning Deltarune is where does it take place in the Timeline? Is it a prequel, a sequel or an Alternate Universe in itself?

So obviously, Deltarune has to take place in a separate Universe, since Catty and Bratty hate each other, Undyne doesn’t know Alphys, Asriel is Alive etc etc.

But I think in its connections to Undertale that Deltarune is a prequel to Undertale, but ONLY for the characters of Sans and Papyrus. I think that this is the Universe Sans and Papyrus originally came from before they ended up in Undertale.

And there is a whole lot of Evidence to Support this.

So firstly Undertale. It’s obvious in the game that Sans and Papyrus comes from a different universe to the Universe presented in Undertale. Sans mentions it himself that he might not have originated from this world in the Genocide run.

And then theirs Sans hidden Lab. This Lab has SO many connections to Deltarune.

Firstly the Blueprint.

Isn’t this the exact same blueprint that we see Lancer and Susie working on?

Of course, this could just be Toby Fox reusing files, but knowing him and the amount of effort he puts into these games, especially these little lore secrets, I’m inclined to think differently.

And then there’s the drawing.

Don’t Forget. It’s a line repeated throughout Deltarune. Over and over and over, through the music and the litemotifs. And three people that we don’t recognise? Could it be Kris, Susie and Ralsei: The supposed heroes of Deltarune?

And one final thing. Sans seems to have an unwarranted hatred towards humans in Undertale. Plus the fact, that unlike most of the monsters in the game (Except for the ones who knew of a human presence) Sans recognises you as a human from the moment he meets you. So why does he hate humans so much? Perhaps… Perhaps in a previous timeline, something happened with him. Something that ripped him away from his home and landed him in the Undertale world. Perhaps something bad concerning a human, who we can see isn’t exactly the most trustworthy.

When Deltarune finally comes out, it’s very likely that our choices don’t matter. They didn’t matter in this demo (Well they did to the tiniest extent), and we’re constantly being reminded of the fact that everything in this game is fate and that we have no control. So I believe the final ending of Deltarune will have Timebending, Universe bending impacts that we have no control over. Something that will greatly impact Sans and Papyrus.

Anyway that’s just my theory on Deltarune.

Hope you all like it.

That’s exactly what I was thinking

it would explain this 

sans knew what the sun was and wasnt surprised BUT that also brings one hole in the theory. Papyus DIDNT know what the sun was. So may i propose a little amendment to the theory? Sans is from the deltarune universe but papyrus isnt. The papyrus that sans does everything he can to make happy isnt the same papyrus he grew up with.
