You might be interested in Aaron's blogpost (http://themadirishmnblog.tumblr.com/) because he talks about the Nature vs. Nurture Debate. Your critique falls in line with the nurture side of Marko and Alana, but it's interesting to look at their nature side too. Although they both had upbringings in opposite sides of a war torn society and were ultimately participants in that war, they both became fugitives, running away from their species together. Their "nature" kept them apart but at the same time, its keeping them together, especially through Hazel.
