There is the potential that, like the last game, the Bi-Han / Kuai Liang brothers are just alternate skins for Sub-Zero, but until there's evidence otherwise, I think it's best to assume that there's only one Sub-Zero at this time and it's Kuai Liang. With that said, it is completely possible that it might be a Bi-Han skin. I do recall an old source that said that one dialogue exchange between Sub and Quan Chi had the latter say "I have your brother's soul" or something to that extent. With that said, pre-match dialogue does not necessarily reflect canon. One Takeda/Scorpion exchange has Scorpion returning to Quan Chi's service, something I don't expect to happen in the main storyline. It could just be that non-canon dialogue exchanges leave the possibility open, regardless of story mode's canon.
