Deltarune theory!?!?

Hiya, i have a theory about what might happen in the future chapters in Deltarune, lemme go ahead and say what it's about

[SPOILER WARNING!!!]

So, at the start of the game, the player is asked to make a vessel, right? Where you choose characteristics for it and stuff. Yeah, this moment reminds me of anyther part in chapter one, where you make a "machine to trash you", where your choices were later on used in both chapters one and two, in a battle where the machine-thing is against us. And this has me thinking, this reminds me of the vessel situation at the start. So, what if, like in the other situation, the vessel isn't really exactly "discarded", but is actually just saved for later to be used in the game, as i suspect at the last chapter, as a final boss? Because, if you think about it, it could be possible, since that's definitely a thing that Toby would do. Also, proof that this theory could be true at the end is that I saw a post somewhere about how the vessel is actually saved in the game files, not exactly "discarded" Now, I'm not making you believe in this theory or anything, but it's just an interesting one, and I'd like for you at least to say your opinion on it. Thanks!
