If you think your theory was the only reason why I believed the statue couldn't be of Gaster, you got it wrong.

It's because if Gaster wasn't retconned from the timeline, I have no way to explain the Gaster Followers. The followers that when you're around, your phone won't work. The followers that one of which talks about a world just like this one, except you don't exist. Where everything just carries on without you. The followers which, as Deltarune shows, weren't always this way. (By the way, explain how they became un-Gonified by your theory on Deltarune.)

The name "Gaster" was never spoken in the entire game, by anyone other than the followers. Typing in that name crashes the game. Sans has to put a note in a special room saying "don't forget"... Despite the fact that Sans isn't one to forget.

If Deltarune is Gaster's Experiment, then perhaps even the photo of the three smiling faces can be explained. The three smiling faces are the heroes of the Dark World. We've already figured out that Sans worked with Gaster, after all:Why wouldn't he partake in the experiment?

It's always been a mystery why the Skelebros appeared to just "show up and assert themselves". But if their origin was in Deltarune... It makes perfect sense. And if Sans is a Darkner... That'd even explain why he bleeds.

But those two theories appear to be mutually exclusive-As in, they can't both be true. If Sans is a Darkner, then he couldn't have both been a part of the experiment (and we know he was), and created by it (which would have to be the case if Deltarune is Gaster's Experiment. Likewise, if the Dark World was created by Gaster, with Sans on his side... Sans couldn't have came from the Dark World, and go on to create... himself.

One could attempt to fuse the two into a more complex theory, ala "quantum gravity", by saying that Sans and Gaster partook in the Deltarune experiment.. Made Deltarune Gaster... And the original, Alpha Undertale Sans turned into a Goner with Gaster.. While Deltarune Sans eventually found his way into Undertale, becoming the Undertale Sans we know today.

Gaster was aware of the Deltarune prophecy, and the three heroes, and even by my theory, it's possible to cross between the worlds of Undertale and Deltarune. Perhaps Sans did take some inspiration from the world of Undertale, and copied an almost-perfect clone of Grillby's. We'll just have to see if it's Grillby's or not in Chapter 2.
