It's important to note that one of the reasons Alex had been arrested was under the suspicion he had joined the Blind Eyes. Oran was quickly learning this was not the case and that Alex was, in fact, just crazy. 

While Alex vented his anger, Oran hung his head in defeat. It wasn't that his family didn't already see him as a failure, but now he would be even more of a disappointment. Accidentally associating himself with a criminal might even get him tossed out of the family. 

When Oran was a child he spent his time drawing pictures of space ships and mechs. He read manuals for fun. While other children of high ranking parents prepared for lives in the public eye and readied themselves for things like inspiring speeches, fancy fund raising dinners, and learning how to pose  for the paparazzi, Oran colored blueprints and explained Vitruvian principles to his dolls.
