So, um, I'm sure I'm not the first to notice it but....
I mean, I noticed that track that plays in Hometown near the ending of Chapter 4 musically references "It's Raining Somewhere Else" from Undertale but....... okay, fuck, that name....
Honestly I kinda figured we'd get a track with a name like that in Deltarune and yet it still surprised me regardless???
Like, the implications............. It works super-well with the 'Sans Undertale is actually Sans Deltarune" theories, considering the places "It's Raining Somewhere Else" plays in 'Undertale'
During one of Sans' most sincere and serious scenes in the Neutral/Pacifist Playthrough where he muses about whatever it's worth it to 'go home'
and in his secret workshop, with the strange machine and the hidden Deltarune teaser.
"It's Raining Somewhere Else" is, in that context, the theme of Sans' hopeless already-gave-up-on-it wish to go back to "the place where it rained". To Hometown.
But even without Sans directly travelling from the Deltarune timeline to the Undertale timeline.... Even if we assume that Undertale and Deltarune are parallel but separate lines that never meaningfully interact, the parallel being drawn here is still very emotionally powerful.
The main focus of the Sans' 'date' scene is his story about befriending Toriel behind the door to the ruins and the promise he made to her. They've never seen each other's faces, they haven't even bothered to introduce themselves by name. There is some connection there, but it's blocked by their secrets and obligations and also a giant-ass stone door.
And somewhere else, in another world, it's raining, and Toriel ducks into Sans' grocery store and they spend an entire night drinking and having fun.
A lot of people assumed the rain here is a metaphor for depression and sadness of Sans or Toriel or both. But I think, with that track, it's more likely that the rain is the happy moment and the bond these two share in the Deltarune timeline, somewhere else.
Of course, depending on which ending you get, you can bring the 'rain' to them. Sans and Toriel can meet in the Undertale timeline and become friends and have many happy nights dancing the Jitterbug or whatever. But... they also they might not, depending on the Player's actions before and after this scene. Toriel might even be dead and that 'rain' will never come. And either way, at this moment Sans has no reason to think he will ever get a chance to truly meet the funny lady behind the door.
Is it sadder to think that this is the same Sans who danced with Toriel Deltarune, who probably knows that it's the alternative-universe counterpart of her beyond the door but also think there's little no chance they'd ever meet or relive that connection they had in the Place Where It Rains?
Or if it's sadder if it's a different Sans who doesn't even know there's a version of himself and the mysterious lady behind the door, dancing and laughing and having the time of their life, Somewhere Else?
