I remember the days when just being out of high school meant you were old, and now half my RP partners have kids.  I'm puzzled as to how I became a young'un.  

Well, I'm very happy with it.  It was so immersive!
I dunno why, but 'multi-racial lowlifes like this punk' made me snicker.
As a matter of fact, the way you're describing Alexander really makes me think of this actor I worked with a summer or two ago.  Biracial, the longish hair, the appearance of not having bathed recently and ratty clothing (those were costume decisions not the guy himself).  But it's weird because as much as the descriptions kinda fit, I still can't quite see that actor as Alexander.  Maybe it just feels too weird for me to project this person I know into this story.

I've started coming up with some inspiration for the underground.  It got more fun when I decided to play fast and loose with the laws of reality.
