Frost Mortal Kombat

frost from me is a very cool character but the way the mortal kombat games built her up was short and odd my first time seeing frost she won the tournament was standing there with sub zero great pair these 2 are but then they have here reach for a power source or some kind of portal witch I forgot because I have not played the game in a while then she gets frozen while a shocked subzero watches on. then in another game she wakes up to learn that subzero had frozen her then in mortal kombat x she from what I got was trying to help subzero after the guy was about to kill him then sub zero saves him preventing frost from killing him but then he freezes her frost beginning and endings are I feel could have been better why cant she along side others have a better story and be more involved in the mortal kombat trilogy frost one of my favorites. correct me if in any way that I'm wrong or confused but a lot of what I said and watched from the games showed me this
