Batman: Arkham city

Template upon template. This one should, that one should, these ones should. No one owes anything to anyone; you just need to think for yourself and consider all the possible reasons why a person is behaving in a certain way, etc., instead of drawing conclusions on the first day just because something is indicated in a template. And, of course, an autopsy is absolutely necessary because without it, people can't figure things out on their own, and after the autopsy, there will supposedly be many options – whether to believe them or not – even though they were there from the beginning.
Analyses are obvious facts that absolutely anyone can write down, and they don't provide any useful information (unless, of course, you're playing according to a template). You can suspect everyone and come up with a reason for each person, but you can't rely on that. This is just empty chatter, not the kind of information you see and which might actually contain a piece of important information. It's time to learn to think more broadly, instead of being limited by some nonsense that you invented yourself, and then use it to compare others and accuse them of something.
