First brother made a choice he lied and later when adopted family of girl wanted to take him too they were told he was adopted by someone else ( they didn't take him at the start because they didn't want to mess up succession rights). Second brother isn't only kid in orphanage so why him and not other kid? What I assume brother and sister won't have problem to keep in touch from now and if there is really someone in queue for title it more safe to stay in orphanage and just keep in touch ( a special that it looks as a good institution in the story)
Am I the only still upset that the brother of the adopted girl was left behind at the orphanage??!!
