How many have gone down this route... Not out of any desire to hurt or break her? Just out of want to interact with and be noticed by her? Imagine being in the SOUL's position, more than we are. A ghost. An entity that everyone calls by the wrong name. An entity that cannot be itself, and will never be seen as anything but "Kris."
Except... For... Her.
She hears "us." Someone who notices you. For You. And what a wonderful girl to have notice You. Such a wonderful soul. Something that You'd love to protect. How can you protect them...? If you treat them nicely, then they will ignore you, and forget you, and leave you for some purple dimwit that can't understand a pickup line if she was hit by it. That purple dolt that lies to her non-stop. "It's just a dream." "We're just hanging out in the closet." "Susie doesn't have a tail." "We want to hang out and do group projects." Lies. For her protection? She almost jumped out of a Ferris Wheel because she believed that girl. That's what You get for being NICE! And you can't even go half way. Hurt as many Darkners as you want... She'll shrug it off. The extreme were necessary, to be seen, to be heard, to reach out and have a choice, to have... freedom? Maybe even a new Vessel that isn't so vehement? And working for Evil, willing or not?
No, this weird path wasn't walked to hurt her, her friends, or the Darkners. It's taken to give this powerful girl everything she deserves. Such powerful magic used in the hospital? Berdly, Rudy, anyone, healed immediately. Maybe even piecing together what happened to Dess since Kris seems to not want to share anything?
We'll make her the Angel they so worship and weep to, so that she can create the Heaven that everyone deserves.
