Theory I thought of when going to bed last night.

So my theory is that the disappearance of Dess and Kris and Carol not wanting the fun gang to get the bunker code is related so basically when they were younger Kris Asriel Noelle and Dess decide to explore the bunker and in the dark world there they were attacked by something Kris Asriel & Noelle escape because Dess either tried to fight off what ever attacked or was captured and later becomes the knight Kris and the others tell there parents but only Carol believes them Aerial and Noelle repress the memory of that day but Kris remembers and Kris and Carol aren't evil is just that is our prospective because they are getting out way but there are trying to protect people Kris the friends and family and Carol the town in general I do have some evidence of this in chapter 3 when you are getting the shadow mantle Kris actively fights you going to the bunker and in chapter 5 weird route Kris tries to keep Noelle's head above the water but what do you guys think?
