Well, the story isn't over yet (the final chapter is up now, by the way). And I agree with you: it's really not explored enough, particularly when it's such a complex topic and informs so much of his character...

I'm working on the scene depicting the healing of the intercision now, although it'll take a while to finish. After that, I think I'll move into the ramifications of House's PTSD--basically, the week before this story opened. (Unfortunately, that may have to wait until the semester ends.)
