I actually saw this started before it was closed for being too off topic in another area, but now i've gotten a little lost, maybe I missed something since I never really played MK4...

What's the story with two Sub-Zero's ? I know that there was the original in MK, killed by Scorpion... then in MK2 there was the younger brother who was not technically a bad guy, and was spared by Scorpion from being killed b/c he wasn't the same guy who he thought killed his family off... then in MK3 the younger Sub-Zero was a renegade against the Lin Kuei because he was technically a 'good' guy, Scorpion didn't really have much to do with Sub-Zero at that point. I missed everything from MK4, so don't know anything at all about either of them there... MK:DA now has him as a good guy, and Scorpion is going after Quan Chi and it's as if there are seperate storylines overall. Now there are rumors of MK:D having the older Sub-Zero OR being the younger brother?

Who's a good guy, who's a bad guy, who's older, who's younger, and when did the storline with him and Scorpion break off?
