History Fridge / ZeroTimeDilemma

* At least in the English version, [[Creator/LauraBailey Luna]] and [[Creator/EdenRiegel Diana]] are voiced by different actresses and thus have distinct voices. This inconsistency can be explained as Sigma mentions he couldn't exactly replicate everything about Diana to Luna, and likely, her voice was one of them.
** Another explanation is that Sigma purposely gave Luna a different voice from Diana, since he tells Diana he grew to love Luna like a daughter, making it also likely he designed Luna to be a daughter Diana never had, although still heavily resembling Diana.

** Also, as mentioned above Sigma's [[spoiler: jumping abilities were likely augmented by those accidents he suffered in his childhood. He specifically mentions that, when he fell off the roof of a building, that he had no idea why. Delta could have forced him to walk off with his Mind Hack abilities.]]

** Also, as mentioned above Sigma's [[spoiler: SHIFTing abilities were likely augmented by those accidents he suffered in his childhood. He specifically mentions that, when he fell off the roof of a building, that he had no idea why. Delta could have forced him to walk off with his Mind Hack abilities.]]

** Ditto for [[spoiler: timelines where Akane dies in 999]]

* While the most obvious hint of [[spoiler: Phi being Sigma and Diana's daughter]] being the fact [[spoiler: she's a natural redhead with obvious red eyebrows]], there's another, much more subtle hint of this connection. Pay close attention to Phi's eye color: while her eyes are blue [[spoilers: her model has her eyes rendered in a way that has a very noticeable amount of gray...]]

* Sigma mentions that he died at least three times during his childhood. If [[spoiler:the transporter works by sending data back through time regardless of a BootstrapParadox, and thus Delta's 'birth' and resonance abilities remain the same, there could still be timelines where Delta becomes 'divinely inspired' and releases Radical-6. And that means that there'd be no one to stop him.]]

* In [[VisualNovel/NineHoursNinePersonsNineDoors 999]], one of the bad endings involved Junpei drowning in a pool of water...and if his abilities in this game are any indication, he could well remember that. So what exactly was going through his mind while Zero's gas trap suffocated him?

** Diana is a porcelain doll, a doll made to be warm, inviting, and comforting, but as anyone who owned one can attest to, will crack under time and pressure. If Diana dies in a timeline, the status screen shows the doll with a shattered face falling apart, possibly referencing an eventual fate of [[VirtuesLastReward someone based on her]].

** Mira, a cold, emotionless, and uncaring person wrapped in layers of FanService is a dress-up doll, like a Barbie or Bratz. Dress them up all you want, they still don't break their empty stares.

* In C-End 1, you learn that Q is still alive. At the the same time the anagram is revealed as "Together with me, we are ten". By this point you've likely already gotten the D Team End 1, during which "Q" is shown to be [[spoiler:seemingly dead. This indicates that the "Q" spoken off throughout the game doesn't refer to the young boy.]]

* After Virtue's Last Reward, the ending tells us that some characters ( Like Kyle ) are maybe gonna join somehow Phi & Sigma in the past to help them deal with Radical 6, except they're nowhere to be found in Zero Time Dilemma. [[spoiler: That's actually normal. Those events take place in the Bad Ending leading to Virtue's Last Reward when the Decision Game failed and Young!Sigma joins his young body back with two cybernetic arms and one cybernetic eye. So not only the ending of Zero Time Dilemma happends in a completely different timeline, but it's not even the right timeframe either. It's likely those events will never take place after Zero Time Dilemma's golden ending.]]

* In the final ending, [[spoiler: removing control for Carlos' final choice implies that every decision across the entire series was Delta taking control for an instant. It's more likely to be "?"/the Player from VLR than Delta as Delta would not be able to control them in the far future and past........]]

* If you thought D-END 2 was a TearJerker before, another thing to bear in mind: [[spoiler:There is a pantry full of food in the complex that is seen on one of the other paths. Diana and Sigma just never see it because it isn't "in their ward". If Diana had her realization about the matching-up of the wards at any point during that 10 months, she and Sigma could have been saved. On one occasion, Diana throws an object at the door of the lounge. If only it had hit the wall instead..]]

* In the [[spoiler: twins ending]], Sigma and Diana [[spoiler: spend months starving themselves waiting for the transporter to come back online, eating only the food in the lounge. In this timeline, they never learned that there was only one ward, nor did they know of the existence of the pantry ... which would probably have more than doubled their available food. With that they could have lasted another 10 months, and sent copies of their adult selves back in time. Of course, if they'd raised their children themselves, Delta might not have turned out the way he did ...]]

* How in the world did Sigma and Diana [[spoiler: survive on half a normal-sized can of food a day? Unlike Literature/TheMartian they don't have a stock of vitamins to fall back on, so they need a balanced diet. Best case scenario is something like beef stew with vegetables, and half a can of beef stew a day isn't going to top 300 calories at best. The human body needs 500 to avoid starvation and it'll still be in a sorry state. Lasting a couple of months is one thing, but almost a year? It's not helped when Sigma stops eating ''at all'' when he finds out Diana is pregnant. Did Zero specifically go come up with his own high-calorie, high-nutrition recipe for such an occasion?]]
