I'm thinking of kris repeating berdly's name in shock when you try to tell ralsei that you are going to the festival with berdly of all people. Thinking about the conversations we only get to hear half of, where kris presumably tells ralsei and susie that ralsei and asriel don't look that much alike. Thinking about all the times where kris changes the prompt we give them into something that they'd prefer to say.
Kris talks. They chatter, even, but we as the player don't get to hear it. They don't get a text box. We only ever know that they spoke at all from the reactions of other characters, and even then, we rarely know exactly what was said.
And part of this is that whoever the deltarune narrator is seems intent to pretending like kris doesn't exist. You check the mirror, and it says, "it's only you". Kris plays the piano and it says, "your hands begin moving on their own." If kris speaks without your permission, the narration doesn't acknowledge it at all, committed to the lie that kris doesn't exist beyond their role as our vessel. But that's not what this post is about.
This post is about how it's entirely possible that kris has tried to talk to us when no one else is around. They could have tried to tell us their plan, or begged us not to make certain decisions, or explained that we don't actually need to steal asriel's 5 dollars because they have a piggy bank buried in the front yard. Kris could be asking us questions, or asking us not to look for the bunker password because they have a plan and we should trust them, or asking us to let them sleep a bit longer, and we the soul just carry on the same regardless, their one-sided monologue falling on deaf ears. We would never even know, because of how thoroughly the narrative of deltarune has denied kris a voice.
