oh, yeah, and the reason that Sub-Zero has cast Frost out is because when Quan-Chi and Mavado beat Frost (and then...well, you know. It's horrible, I won't even say it, for fear of getting banned. You all know), they decide to possess her and use her for services to help vanquish the Lin Kuei. Frost then begins to fight against the Earth warriors, and Sub-Zero.....Sub-Zero feels he has no choice but to kill her. However, to prove her loyalty to Sub-Zero (maybe to throw him off?) Sareena volunteers to kill her. Sub-Zero tells her to just beat her instead.
Eventually, the
time comes and Sareena and Frost face off, and Frost is taken down. She is tied up for the rest of the wars. During these wars, Scorpion (who knows of Quan-Chi's magic because he's got his own storyline) helps to rid Frost of her evil tainted soul. He does it as repayment for trying to kill him all this
time, and because Sub-Zero wants Frost to suffer and not die, because he knows Frost could've killed him and that jealousy and fear is starting to takes its toll on him (because Sub-Zero has his own storyline. Some dark force is tempting him to give in to his emotions).
When the battles are done, Sub-Zero leaves her out into the barren snow wasteland, telling her she betrayed his
trust by disobeying his orders, and that she has proven she has no discipline (but more importantly because his soul has become darker from Frost's near victory). This leaves Frost emotionally broken down, and physically ill, as not even she knows yet that there is a dark child within her (cause of you know what) that may carry a dark prescence in later years...
