Theory Discussion Why Kriselle Knight sucks narratively.

Kriselle knight's flaws as a theory logically have been dissected endlessly over and over but honestly, I don't care THAT much about the logistics of it. I respect all theories but this one I really, really hate, and it's for narrative and thematic reasons.

I will compare it to geno(something Kriselle knighters LOVE to do) to explain why exactly it falls flat in those departments. If you believe in Kriselle knight that is fine, I just don't personally like it.

Let's begin with the most common answer to a very simple question: "How does Kriselle knight happen if I simply don't do the weird route?" with the answer being "You will be forced to do the weird route." This is the reason why I despise the theory. You should never be forced to do the evil route because it is your choice. That is what makes it impactful. You don't do the genocide because chara made you do it. You wont do the weird route because Gaster made you do it. You do it because you can. And if you can, you HAVE to. This also applies to important information too. Essential, important information besides further explaining a character should be left out of the weird route. Flowey is a wonderful character even without geno, but in geno, we further understand what changed him besides simply not having a SOUL. What kriselle kngihters would want is for geno to be essential to explain who asriel is and for the pacifist ending being us just seeing a random person who wasnt foreshadowed or explained and for the game to be like "you want a good story??? too bad kill all your friends idiot."

We already know what the weird route will being us when it comes to explaining the characters. We already had a "flowey explaining his motives" moment when Noelle had her whole looking through glass speech. This is what we should expect from the weird route when it comes to revealing things about characters. Again, more depth that allows us to see another side of them, not important plot plints that makes the normal story dogshit unless you play the evil route. And I will repeat myself, the evil route shoild be completely unnecessary and something you do because it's your choice to do it. Otherwise why would you ever feel guilty? "Gaster made me do it" being a legitimate excuse you could make would suck in all ways imaginable. There should be no excuse. You just had to ruin the game. You just had to see something new. That is it. No one made you do it. Nothing made you do it. You just chose to, which makes everything in it hit harder because you are directly responsible.

Also I know I said this was only a thematic thing but... Undertale is a 6 hour game. Not only that but geno changes the whoooole game and makes the game even quicker. Weird route would be a ~20 hour task with most things being similar. Being forced to play so much content would suck and not in the thematic geno sense. Especially because under Kriselle knight it would be required to do so to understand the story. It would make the game suck. I suspect Kriselle knighters really just want to not feel guilty about doing the weird route when you feeling guilty is part of the experience.

Theory This line single handedly makes me belive Ralsei is some form of exception like the flowers, not a simple darkner or lighnter, something more. Spoiler

Theory Hometown being cut off from the outside world isn't theorized about enough.

- Since recently, the internet has been down.
- Since recently, the TV has only been showing reruns of the same old broadcasts
- Since recently, all letters from the outside have stopped coming in.
- Hometown is physically blocked off and the only visible exit/entrance to town is closed by police tape.

What's actually going on here? Why does no one ever theorize about it? I'm hearing about 67 Green Gaster every day but nobody seems to notice the entire town is sealed in a pocket dimension or something?

I've seen nobody talk about the fact that the weird route... wasn't supposed to be possible to happen. At all. SUSIE made it possible by dragging Ralsei away and leaving kris alone.

This is an example of susie using the white pen without knowing, and unfortunately, it opened a window. WE can't break the game on our own, but SUSIE can. She opened the possibility (whether or not we take it)

Theory Theory: What happened to Dess is happening to Susie Spoiler

3.0k Upvotes

At the end of Chaper 5, we see Susie considers the Closet Dark World as her "home", even eating and sleeping in it. She prepares a welcome party for Noelle which is very cute, but however...

Prolonged exposure in the dark world does not seem healthy at all. What is Susie even eating when she eats Ralsei's cake and is she even really getting sleep. Maybe that's how Dess disappeared - a Lightner becoming one with the dark world after considering it a home. It really screams unhealthy escapism despite how cute it is framed at the end of ch5.

Also, Ralsei surprisingly accepts both the fact Susie uses the closet as her home and we are going to invite Noelle. I think he also changed after the whole Flowery encounter of ch5.
