alright, so if we do end up fighting Kris in the last chapter of Deltarune, we will most certainly win. For we are the player, and we have the power of saving and loading. Debatably, Kris has this too, but either way the end result is the same- This will be a fight of iteration and endurance.

I hypothesize that this fight will have two (or three, depending on how you look at it) endings: You persist, or you relent. Persistence would likely look like a LOT of grinding, figuring out which actions in what order will allow you to "win" and take control back over Kris. And relenting, or perhaps convincing them to relent, would look like A: fleeing or mercy, or B: the same thing as persistence, but choosing to pursue mercy. The third option would be death, and subsequently giving up.

Now, we must remember that Deltarune is a 2018 video game developed by American indie developer Toby Fox. Deltarune originally came from Toby's fever dream portraying the ending of a video game. So there's every chance that rather than having the option to either fight to achieve mercy or simply give up and die, you can only die. That IS the only way to free the game from the player. Any other way, and you'd still be in control.

This option also would align with Toby's "there is only one ending"- The ending is persistence, and taking over Kris again. The other "endings" are just death.

This alone makes me inclined to believe that that's exactly how it's gonna go. The only thing that makes me doubt this is how Deltarune is a commercial venture, and that's a pretty unsatisfying "ending". But I could absolutely see Toby doing it anyway.

For we are the player. And if we fight for it, we WILL win. But winning means making Kris suffer, and the only way to avoid that is to no longer fight.
