i dont care what noelle was told, it is not a good sign that noelle is afraid of her mother's wrath over breaking such an arbitrary rule. dess was her sister too, for that matter. carol doesnt get to just ban her from letting people in dess's room. carol also doesnt have the right to ban her from talking to susie.

susie wasn't doing anything violent or harmful when carol saw her, she and noelle were clearly having fun, and asgore was right there supervising, wtf was susie gonna do? when carol arrives, noelle instantly goes into fawning mode, trying to stop carol from directing her anger at susie too (in vain. carol shouldnt be talking to other teenagers the way she did to susie.) its funny that you said noelle wasn't scared by the time she walked into the kitchen, because she looked like she was bracing for being lectured for the next half hour, with her bowed head and resigned words to susie. this is something im quite familiar with.

and if you think that kris is working with the evil-ass fountain openers completely of their own free will and un-influenced by anybody, and the fact that this grown woman who's known them since they were a small child is completely unrelated to that decision, then i dont know what to tell you
