History Fridge / FinalFantasyVIIRebirth

* The fact that Sephiroth shows up in the Church vision of the Pomeranian Stamp timeline Aerith shows that he is well aware that besides Cloud, she's ''the'' primary obstacle to his goals. And it doesn't matter what she does, how she aids herself across timelines or how she attempts to hide, he will absolutely murder her every single opportunity he gets because she dares to resist his plans. So long as Sephiroth's evil exists, he will kill her, again, and again, and ''again'', effectively creating a warped meta perspective that she must die as fate desires, because Sephiroth refuses to let any threat to his plans slip through his fingers. It also explains why he doesn't immediately kill her in the main timeline as she stands no chance against him with her White Materia depowered by the Black Whispers.

* During the Combat Trial, Sephiroth has the reraise materia, and considering that using the CombinationAttack gives him unlimited magic use, casting it on himself and Cloud is advised in the tougher battles. Because of course Sephiroth giving himself and Cloud the power to defy death is right up his alley, and Cloud can be right with him in doing so.

* This [[https://static.tvtropes.org/pmwiki/pub/images/party_96.jpg artwork]] of the main cast shows subtle hints of their fates and roles in ''Rebirth''. The characters standing on solid rock end up surviving the events of the story while those stepping on dirt have died at some point. Notably enough, Barret is standing on both dirt and rock, symbolizing both his death and revival in ''Remake''. Also notable is that Aerith is the only character who's seemingly walking forward instead of remaining stationary like the rest of the party, as if to say she's about to AscendToAHigherPlaneOfExistence. Meanwhile, Cid and Vincent are portrayed on each side waiting in the wings to indicate their DemotedToExtra status.

* Sephiroth seemingly knows how fate should go, how he should be losing normally and takes extra measures such as weakening the White Materia of this timeline to try to make himself win more readily. And yet despite all of this, and getting his hands on the Black Materia early... he ''gives it to Cloud'', while seemingly imparting information for the party to head directly to the Northern Crater instead of any longer routes around. Sephiroth was disappointed in Cloud managing to overcome him here, but he still actively works to send the young man over the DespairEventHorizon, and is still exerting some control over him. Considering he wants to [[WeCanRuleTogether make a very direct pawn of Cloud]], it's very possible that a much worse fate is in store than simply abandoning Cloud to be washed up in the Lifestream again.

* Red XIII being able to sense Aerith at the end should also be a reminder that Cloud wasn't the only one Hojo had experimented on. As shown in Red's trial at the Temple, he had been captured by Shinra troopers to be one of Hojo's experiments, so there's also a possibility that whatever Hojo did may have combined with the physiology unique to Red's species that might have allowed them to have some sensitivity to the planet yet not to the Cetra's level.

* Part of the World Intel for the Gongaga Region mentions how the denizens there are descendants of the Cetra that had decided to settle down. Genetic deviation and changes over time since the Cetra's fall could provide an explanation as to why Zack wasn't as affected by Sephiroth's cells, probably being one of the very rare few people with higher resistance/possible immunity to Jenova's cells. When factoring in his being an IncorruptiblePurePureness {{Determinator}}, it combines both [[NatureVersusNurture nature and nurture]], something which could explain Hojo's disappointment at Zack due to the professor's predisposition towards focusing on the "nature" of his subjects.

** Sephiroth is at his strongest when Cloud is at his mentally weakest, always seizing power over him or overcoming him, and it's when Cloud manages to solidify his mind that Sephiroth loses. Either Aerith reinforcing his mind instead of letting it fall to despair, or Cloud ''refusing to acknowledge Aerith die'', has kept him stable enough to actually drive off and temporarily defeat Sephiroth here. In a way, if he ''is'' cracking up, Cloud's insanity is ironically stronger than Sephiroth's manipulation, and if we take the positive example of Aerith's aid, she's working damn hard to undermine Cloud's greatest weakness.
* One going all the way back to ''Remake'', Aerith had always shown a particular interest and fear of the sky, especially at the end of the game when she finally leaves Midgar. In the context of ''Remake'', it's assumed that she's simply not used to seeing an open sky unimpeded by Midgar's plates. However, with the added context of ''Rebirth'', it comes to light that she's concerned about the giant dimensional rift in the sky that only she can see.
