Those are both very viable options. Also, I doubt that there was a third brother. There was talks of there being a sister though. Now that I think of it, what if Frost is the sister of the two Sub-Zeros? Being that the two brothers were kidnapped by the Lin Kuei, they wouldn't necessarily have to know about who the sister is.
