I just hope this doesn't get too far into cringey "realist" logic. I mean we all know the Vulcan absolute logic fallacy. The old, this character is being realistic in thinking about things and therefore all the explanations are correct. Usually because thats as far as the author can work things out. When its truly bad is when you get Chuuni syndrome or "immortality is horrible cuz people die and you don't" arguments used as truth.
