Rain's mother? (possible spoiler if unfamiliar with MKA bio/ending)
So who might Rain's mother be? I wouldn't be surprised if in the next game or sometime down the road they say it's Sindel and that Rain and Kitana are half siblings.
Also, it seems funny that Argus is a god character in MK going around having kids with mortals. Don't think any others did. Rayden and Fujin did not.
