I cannot remember now in which thread Mako explained to me his loop theory, so I'm posting this here, although it follows on from that discussion. These spoiler threads are proliferating like weeds. Anyway, I read this on tumblr (don't switch off)

Sephiroth, in the Lifestream: “You mean to tell me my whole life was pre-determined because you have some convoluted plan to rid yourself of Jenova and reconnect with humanity?”
Minerva: “uwu”
Sephiroth, one foot in a portal that can fuck with all of time and space: “To hell with that nonsense.”
Minerva: “D: !!”
Mako's theory (please correct me if I'm wrong, Mako) was that the activating of Holy caused the Planet to create a time loop in which it could review all the events leading up to the summoning, as a way of evaluating whether humanity should survive or perish. However, Sephiroth screws up this mechanism by entering it. His goal is to alter the outcome. His intrusion into the loop forces the Planet to generate the Whispers as a means of keeping things on their original track. Sephiroth lures Cloud and Co into defeating the Whispers, and now the train of destiny is off its rails: it could go anywhere. This theory is rather convoluted and requires a lot of further explaining as to why the Planet allowed Shinra and Sephiroth to exist in the first place.
Saanphoenix's solution is that it was the will of the Planet all along that Shinra and Sephiroth should exist, as a means of ultimately ridding itself of the source of all infection, Jenova. When Sephiroth figures this out, he feels used and exploited
- the way he felt when he first discovered Shinra had made him as a human experiment. So
he creates the time loop or whatever you want to call it, and the Planet sends the Whispers to stop him. Once again, the Whispers are defeated, the train of destiny goes off the rails, etc...
The question then is, if Sephiroth has the power to mess with time and space, why doesn't he use it over and over and over again until events finally turn out the way he wants? Sephiroth's powers do seem to be both limitless and inexplicable. But if he isn't the one who created this portal or loop, then who or what is?
Or are our characters trapped in this loop forever, condemned to replay the same events and die the same deaths over and over for all eternity? Gosh how meta.
