kris is the knight part 2: electric boogaloo
okay I'll do this better soon but the rough sketches of an argument. badly sourced and worsely argued. <3
The game has all but confirmed it for us. how do we know it's confirmed it for us? besides the fucking obvious (constantly fucking with our plans, literally dressed as a knight, literal antagonist smile flashed at us at the end of the first chapter)? dramatic irony. so this video at 4:45 shows Asgore doing the whole "I'll find the creator of the dark fountain and I'll parade their body around town" which is supposed to make us SWEAT. Ralsei, Kris, and we know Kris is the one who opened the dark fountain.
then we have this scene right here (text dump of both note sections here as I couldn't find a short video showing the first one, which just establishes there was a dark world a long time ago)
...which tells us a) black shards were found at the "original scene" a long time ago AND b) it matched with cyber world's dark fountain (which also uh. how'd he find out about that one) c) more importantly Ralsei VERY CAREFULLY picks their own words after Susie asks how long the knight has been making fountains by saying "I thought the knight only... [PAINFUL SMILE] showed up alongside the heroes"
we can't 100% say Kris made the cyberworld dark fountain, but we know that they definitely made chapter 3 and 5's, and Asgore thinks the creator of this fountain and the original's are the same, which implies...Kris.
Now, we could draw a crazy graph trying to divide dark worlds into "made by Kris" and "not made by Kris", which can go a few ways (we see them make 3+5; there's indirect evidence for all but 4), *or* we can read the very obvious blaring signs and understand that Kris has made the majority, if not all, of the dark fountains and can be understood to be the maker of the first fountain.
(there's another long series of speculations to be made about the circumstances of opening the first fountain and Dess' disappearence, Kris' guilt as it relates to Dess, etc, but I don't want to get into that now. The short answer is that I think the first fountain was because of Kris, (perhaps at the behest of a creature with a pointed tail...) a dark world that somehow went bad and resulted in Dess going missing, dying, or otherwise being trapped in a Dark World. I think all four kids were there, but understood it in different ways. Asgore saw enough to believe it, but ascribed malice where it was just a mistake. But gathering the evidence would require a lot more effort than this, so feel free to disregard this for now.)
^this bitch? not the knight from the prophecy.
Most of the time, when people talk about Kris' role as an antagonist, we hear them say Kris is working with the Knight! I think the reverse is more likely; this entity is working with Kris, the Knight; at most they're splitting the role between two parties. We have plenty of evidence from chapter 3 and 4 (coughing, kneeling, refusing to attack the knight) to know that they're coordinating. I also think this thing is (the remnants of) Dess rather than literally any other character, for the usual Dess Knight reasons - lost girl reversed leitmotif (really need to get a music analyst on that), driving drums similar to Raise Up Your Bat (noted Dess song), the bat that turns into a katana...anything else I'm missing?
this is my less-official meta, mostly because I need to source all my stuff much better, and I haven't really written a quality essay. but those of you awake at midnight can have this unhinged ramble.
