History Headscratchers / NineHoursNinePersonsNineDoors

** Nothing concrete is mentioned in-game or in supplementary material about the how. However, we can take the fact that Akane was supposedly the only "casualty" of the first game as implied evidence that everyone in Building Q managed to make it out. We might also infer that the final puzzle in the incinerator was **meant** to be a puzzle that had to be solved to allow a second group of players with digital root of 9 through the door, judging by Gentarou's insistence that Akane must receive the answer to get out; we ultimately never know what is supposed to happen due to the players on the Gigantic escaping through the vent, and Akane wasn't going to be getting any answers from Building Q anyway.

* So I understand Why June gets the fevers and the significance of why they happen, but why does she get a fever when we open Door 5 to see what happened to the 9th man? We haven't even done anything yet to start down a wrong path besides open a Door 5. Since this also happens no matter what, Just checking the door should not lead to her final fate.

** It's all a [[TemporalParadox]]. Akane is seeing into a future where Junpei was able to keep her from dying in the past which required her to create the game. Like most paradoxes the more you pick at it, the more it falls apart.

*** But there was also a pretty good risk of a situation that they couldn't deactivate. What if Ace tried to kill someone else the same way he thought he killed Snake? Then there was the DEADs that were located a significant distance away from the doorway, why would they put them there if the last thing they wanted to happen was them to fail to deactivate?

*** Except this isn't how it works. Virtue's Last Reward makes it clear that timelines in this universe work via a many words interpretation, with Schrödinger's cat as the basis. All the timelines are as real as one another, none are "hypothetical". What happened to Akane in 999 was that she was essentially being the player, so she knows everything that happens in all timelines, while understanding that those aren't the "true ending" where her life is saved. That doesn't mean Akane's live being saved was "true" and other possibilities weren't. Both were true at once. What 999 did with Akane's whole "I know the true ending" thing was just a meta gimmick more than anything that makes any actual sense in-universe. [[labelnote:note]]It's obviously mimicking another similar twist from another of Kotaro Uchikoshi's visual novels, ''VisualNovel/Ever17'', where [[spoiler:the player literally manipulates the events as an all knowing entity, but without it literally being the player in this instance. Akane is basically standing in for that role, as a player proxy, which you can really tell in the way they do the reveal in the narration. You could easily shift around 999's ending a little to make the narrator the player or the player-entity from Ever1y and it'd make as much sense.]] This is probably why some more meta aspects of the reveal don't make much sense, especially when put against information from VLR.[[/labelnote]]

** There are multiple gates. After coming out of the kitchen, the Door 4 group notices that a gate near the staircases that was closed when they'd first emerged from the Mars door was now open, while the Venus gate that they'd encountered was still in place. That's the Venus gate that actually gets opened. On a meta level, this is also probably the reason that the 9th Man is made to fo through Door 5 specifically--because of that gate that forced the Door 4 group through the kitchen still being locked, there'd actually be no direct path to his corpse without reopening the #4 Door.

*** Of course, Snake (who is blind) manages to take down [[BadassBeard Ace]], unarmed, Ace with a pistol, out of a pure frenzied revenge. Clover may have done the same. Furthermore, they likely wouldn't have died instantaneously, June interrupting Clover having her bloody, bloody revenge as the two "murderers" writhe. She was doing it for pure vengeance, remember, and would likely not have stopped at their deaths. Perhaps June finds out at that time, June "was in her way,"as the above troper stated.

* I really don't understand how the iron gate (opened with Venus key) works. I'm not sure I can post a link to wiki page here, but, according to the B-deck map, it goes like this: people who go through door 4 enter the "right" corridor, finish the puzzle in 2nd class cabin, go through Mars door. Now to their left they have the Venus gate preventing them from going to C-deck by stairs, but they can go to kitchen to exit on the other side of the gate and proceed. Okay, fair enough. But the 5-door team goes through the left corridor, which means that after finishing 1st class cabin puzzle they turn out on the "left" side of the gate and can immediately go down the stairs. But that's now how it happens in-game - the 5-door team also has their path blocked by iron gate and has to go through the casino to get Venus key. But that would mean that both teams end up on the same side of Venus gate after their first puzzles, so why wouldn't both teams rejoin in the kitchen or the casino... it makes no sense to me. Also, if 5-door team doesn't need to open the Venus gate, what's the point of door 5 to begin with?

* Door 3 choice: Was there any reason for the gang to do as Junpei said ignoring Santa (who had to hide the fact about the bracelets, hence why he panicked). Couldn't they just wait outside after opening the door and give the middle finger to Junpei for trying to screw them over?

** Perhaps the bracelets were made by modifying existing watches, or they were intentionally designed to resemble digital watches (including buttons) to subconsciously remind the wearer's that time was passing (and thus the danger that the morphogenic field theory relied on) every time they look at their wrists.

*** With how small the door was? Unlikely. The door looked to be designed for people to enter single file. That would allow for maybe two people to get in there at once and that's only if the second person manages to shove themselves in before the bars land. Considering the above headscratcher already determined that it was always planned that there would be three people in here, it's safe to say that Zero didn't see a need to worry.
