Liu has always been Jeff's older brother. One cool thing about the first video was that in it, Liu was presented as extremely mundane and normal, despite the fact that his brother is a homicidal freakshow.

I like the idea of Liu being a normal guy who's reputation is tainted by being related to Jeff, and I wish people explored it more. Instead, everyone just makes Liu a Jeff clone if they even bother to use him at all.
