Chapter 3, the Dark World entirely focused on Kris's personal history, has a ton of references to Dess, from talking about her history with Kris directly to bizarre cryptic shit like the gacha machine secret. There's more about Dess in Chapter 3 than Asgore, Kris's own father.
Noelle is not mentioned in the TV World at all. She's only referenced in the MANTLE game, or if you go out of your way to tell Ralsei you're taking her to the festival. Noelle's relationship with and feelings toward Kris are complicated but she wasn't lying when she said "Even then, there were times when I wasn't sure if we were even friends." Kris was closer to Dess than Noelle.
Establishing Kris's connection with Dess also explains and adds layers to Kris's connection with The Knight, who is Dess.
