You know, it's kind of interesting,
If you really look at everything we've been given, it feels like deltarune was SUPPOSED to be a story about the Dreemurrs and the Holidays.
That was, until Susie came along.
Almost every single major conflict in the game can be tied back to a character from these two families. The dark worlds literally exist the way they do because of Kris and Noelle playing make-believe with them. And Dess is almost certainly the main antagonist of the whole game. In regards to the prophecy, there is enough evidence to support that it was originally meant to be Noelle and not Susie (even if I don't personally believe that theory). And even just the fact that the weird route hinges specifically on Noelle and Kris's relationship says a lot.
The narrative was supposed to be (and in some regard, still is) about how the two families used to be very close, how tragedy struck, how the eight of them drifted apart, and how they all are trying to come back together.
But then along came Susie.
Literally in her introduction, she puts a stop to the intended path by partnering with Kris instead of having Kris partner with Noelle. She inserts herself into the story almost immediately, but not as a hero. It takes Kris, Ralsei, and Lancer to really get her to finally listen. Again, comparing to Noelle, who slides into the dark worlds almost perfectly, Susie is seen as an outlier. Almost like she wasn't supposed to be here. And yet, despite this, she still makes herself important to this narrative and these characters. She's just built different.
But what I find specifically intriguing is that SUSIE is the one who inadvertently brings the families closer. She acts as an anchor for Kris, she pushes Noelle to stand up for herself, and she is the catalyst for the two of them to start hanging out again. She is the one to defeat the King, she is the one to get to through to Tenna, she is the one who stands up to Carol, and she is the one who is defying fate to make her own destiny. By just being who she is, she's made her friends closer than they ever would have been without her.
It's what makes these three such a compelling cast of characters. Even disregarding shipping, they just fit so well with each other. Susie was the change in Kris and Noelle's life that they both needed. And we will see whether or not if that determination can save the world, too.
