Might be just me interpreting things but.. it seems Lahabrea is scarily aware of the type of person he will become later on, like he knows the Praetorium Lahabrea inside out. He almost talks like he seems to know the future in a sense, in that last cutscene we have with him in Elpis Pandaemonium. Then again he is wondering and specifically intrigued about himself and his future and even asks us out about this. Is he just coming to terms with the most likely outcome for him, which is duty above all even if things get dirty ? I think this was the aim of the developers here, but then again..
