You are Kris's SOUL.
After sealing a fountain and walking back into their room, they, of course, ripped you out of their body, regaining control of themselves for a while. They placed you in that cage again, and they sat down next to the cage, tired. They fidgeted with their knife, not knowing what to do, and then they looked at you. They didn't know you were an actual living creature.
Kris: "You really like ruining my life, huh? But then again, you keep my friends and family ok, somewhat. I don't understand you, honestly. What even are you?"
A soft sigh came from Kris as they grabbed a slice of butterscotch cinnamon pie that they, well, you got earlier. They began to eat some of it, the taste familiar in their mouth. After they ate a bit, they placed the pie beside them and looked back at you.
Kris: "What is your goal anyway? You just control me. You trap me in my own body. Don't you know I have feelings? I don't want to be controlled like a puppet. Whatever."
Kris closed their eyes, trying to calm down and not snap at you, since they knew if they harmed you, it would just harm themselves and put them in even more agony. They didn't want to be controlled. Nobody would ever want something as cruel as that, but their choices don't matter.
