[[WMG:Chiffon the [[CowerPower Cowering Power]][[JustForPun house]]]]
In chapter 4 Chiffon stands up to Satellizer, then immediately cowers behind her sidekick. Several chapters later, we find out that Chiffon is the strongest third-year of the campus. She should have no reason to fear Satellizer. So why would she cower from Satellizer's DeathGlare?

That's actually her {{Reasonable Authority Figure}}hood shining through. Chiffon has observed Satellizer for long enough to know that she doesn't respond well to any attempts to [[MightMakesRight bludgeon her into submission]].

Instead, Chiffon tries to, y'know, [[BoringButPractical reason with her]]. "This is a violation of school regulations. Cease and desist, please." The cowering is mostly there to make it clear to Satellizer that Chiffon neither intends nor wishes to fight her.

And it works. Satellizer responds much better to people who [[PolitenessJudo nicely ask her to stop]].
* This isn't so much Wild Mass Guessing as "plain and simple truth."

[[WMG:Gengo Aoi is responsible for bringing the Nova into this world]]
A lot of evidence has come up pointing to the fact that the good man Aoi is not as benevolent as many make him out to be. He came up with all the acceptable proposals for countering the Nova, His family has a unique condition that makes them very effective at dealing with Nova in exchange for eventually turning into Nova themselves and one of his colleges states that he is trying to control human evolution and mentions him trying to bring what may or may not be an AssimilationPlot known as the transcending consciousness theory to fruition. What better way to kick start all these off than by bringing mankind's greatest enemy the Nova into this world?
* Rapidly becoming a much more credible theory, due to the E-Pandora transforming into ACTUAL NOVAS, and the heavy implication that Chiffon was one step from going Nova herself. After all, while Nova invasions certainly are treated as a big deal and cause a moderate amount of casualties among the Pandoras, given the kind of hyper-destructive weaponry the Novas seem to possess, they appear to cause remarkably few civilian casualties and destruction. A rapidly ascending fan theory is that the Novas are simply the evil threat that the government dusts off every now and then to justify keeping total control over the civilian population. (Is that a trope? It seems like it should be) The reason the Nova invasions are getting more and more frequent is that the population is losing faith due to EXTREMELY questionable actions by the government.
** Jossed The Nova are shown targeting heavily populated areas and if the Pandoras don't stop them, they self-destruct IN those areas for massive damage and loss of civilian life. It's only once they find Maria's corpse that they begin targeting Pandora.
** Jossed [[spoiler:Maria appeared before him and apparently warned him about the oncoming threat.]]
* It seems more likely that Gendo has some kind of "instrumentality project" going that takes advantage of the Nova rather than just simply bringing them to Earth.

[[WMG:All of Freezing is caused by a StableTimeLoop.]]
Apparently it all started when Maria Lancelot [[spoiler:appeared before Gengo Aoi at a lake]]. All Pandora technology was made from her. An earlier arc involved a plan to [[spoiler:make clones of Maria]]. Perhaps in the future, [[spoiler:a perfect clone of Maria will be created and, for some reason or another, end up being sent back in time... to meet Gengo at a lake in the past, thereby becoming the original Maria]]. Pandora technology thus has no origin. And if it turns out that all Novas are actually just mutated Pandoras from the future, the whole plot is the product of a StableTimeLoop and none of it has an origin.

[[WMG: The Baptism Between Satellizer and Kazuya will either bring about or stop TheEndOfTheWorldAsWeKnowIt.]]

Satellizer has Kazuha's stigma, and Kazuya is being hinted at as something more than human in some cases. The Baptism has been teased between the two of them for so long, it's impossible for it to not be something extreme either way. Either the Baptism itself will cause some unforeseen catastrophe that threatens to annihilate the world, or it will be pivotal in stopping a world-ending threat that's already in progress.
