Because kaz is being openly hostile to Demi and acting like this is a much bigger betrayal. She should direct her frustration at Luis If she feels led on as he was entertaining both girls but instead even though Liberty tried to play bad witch when they both confronted him in that mortifying firepit scene she’s being bitchy to Demi and acting like what she did was some deep betrayal when it’s the object of the feckin game.Why? The whole situation included 3 other people and Kaz was on the end of it all. She looks dumb as hell, she’s suffered for her choices enough. She obviously liked Luis (God only know why!)
there was also about 20 minutes between the kiss and recoupling. Demi was excited and maybe didn’t want to dampen the mood by saying it to kaz immediately. She could have told kaz but it’s not as though the full night had passed. And like kaz would have gone to Demi first had the situation been reversed. She’d have been squealing to Liberty fist and foremost.
It’s all going to end in tears for Demi anyway
