Yes, I didn't say they were identical, but they have huge points of characterization in common -- they both ACT the same way a lot of the time, at least, after Blake gets into recovery. As characters (not human beings), they're really quite similar. The system you developed posits them as "polar opposites." I'm not saying they're the same, but you can't really say they're "polar opposites" when they're as similar as they are.
