1: So you're just proving my point. They wrote it so poorly in the actual game, they have to confirm outside of the media what actually happened. In game, she literally called his name once, and she said it snapped Wolfgang out of his delirium. That's bad writing. If she did do other things to snap him out of it, why out of the entire half hour, did she not try and get help. Granted, she'd have failed considering the door was locked, but she never mentions the door being locked until AFTER he started attacking her. Any competent person would have tried to leave much sooner, but she didn't. Again, either poor writing, or they're writing the most insufferably dumb character imaginable.
2: Literally every single note shown in game was of a past event. That's the pattern shown, and even though we as spectators know to not trust literally everything, the actual characters in game don't have that sense of dramatic irony as they are the participants. Most people, when seeing a pattern, bases logic on said pattern. It would be strange for everyone to have their letters be of past secrets, but then this random letter for some reason doesn't. As of right now, it's bad writing, but if something does happen with Desmond in a later chapter, I'll happily rescind this critique, but it's a critique nonetheless.
3: Beyond a shadow of a doubt. Never heard that term before? If at any point you believe there is any suspicion that the defendant isn't guilty, the jury issues a not-guilty verdict as there isn't enough evidence to fully pin them at the scene of a crime. If Eva was smart, she could have easily pinned the blame on Diana or Damon since there's just as much evidence that Damon knows where every tool is, or Eva could say she had shown Diana Damon's letter as well. Heck, I thought they were gonna do this as everyone tries to pin the blame on others until you come up with the correct piece of evidence showing that Eva had physically taken the items from the room. Danganronpa does this all the time since in crime solving stories, a stone unturned is a plot point unfulfilled, and I felt pretty unfulfilled.
4: A screwdriver or screwdriver esque object. Most involve at least that, but on more complicated locks, sometimes a bit more. You'd need to find evidence not only of what Eva used to turn the knob, but also a general time of when she could have done so. It would have been so easy to just point out a screwdriver in one of the storage rooms, but then during the investigation you find it missing, then find it stashed somewhere. Without it, it's just a missing piece of the puzzle. It could have also led to having more evidence against Eva, but again, it's another stone unturned.
