Dess was human. She died (possibly in the dark world) but her SOUL's determination kept her from disappearing and she became the Knight.

It's why Kris works with the Knight/Dess.
It's why Kris emulates the Knight/Dess' movement like the finger pointing.
It's why Kris is androgynous. He's emulating the tomboy Dess.
It's why Dess means so much to Kris. She's the only other Human he's known.

>But her antlers
Are fake like Kris' horns.

>But Hoof Shoes
Are in a box with Asriel's retainer. It's obviously not a box of her stuff. They could easily be Noelle's old shoes. Plus there a ton of normal shoes in her closet.

Dess is a human and she groomed Kris.

>Humans gotta stick together, lil guy! There aren't many of us, so it's important we know where each other are! You know, just in case?
>C'mon Kris! Azzy's cool and all but like... he's a monster! He's not as cool as US, y'know? You can keep a few things secret from him, but there's no need to hide anything from me! I promise I won't let anyone know...
>Do y'know there's differences between humans and monsters? Obviously there's our SOUL, but there's a few other things too! Things that... well, remember how I said you shouldn't tell Azzy some things? This is one of those things.
>It's easier if I just... show you, ya know?
>Don't worry, however weird it feels, I'm here for you, alright?
>So... just relax. I'll take care of everything...
