Project Horizons is a project to develop a colony ship.All of Goldenblood's secret Projects seem both useful on their own and critical to reaching and adapting to another world. This may have been Goldenblood's version of Gardens — a way to save ponykind, but by abandoning Equestria rather than healing it.
Goldenblood is Somber.And he knows everything that is going to happen to every character in the story. That's how he's on top of so many things at once.
The Dealer isn't just a hallucination.He may have started as one, but now he is a manifestation of the stars cursing Blackjack.
Discord is the reason for all of the chaos in Hoofington.He replaces all the random junk found in lockers, lured ponies to drive everypony into mutually hostile and powerful factions and ensured that any attempt to help or unite Hoofington will fail.* When Rampage mutates in Horizon Labs, she seems to take on a rather Discord-esque appearance - scales, a wing, a horn from the side of her head - perhaps a hint that Rampage, taint, or both, are connected to Discord in some way?
Taint is, wholly or in part, some product of Discord's body.The chorus in Horizon Labs called Taint "the ichor of the meddler", and only two chapters later, during Blackjack's vision of the stars, she sees "trickster spirits" that "mold and meddle and inspire." Ichor is the greek word for the substance gods use for blood.
Discord needs to be freed to duke it out with the Eater of Souls.Suppose Flux was used in Folly not merely as a buffer, but as the payload; maybe it hurts the Eater because that's precisely what trickster spirits exist to do. They come into a nice, orderly world where everyone hums the same note, and they introduce freedom and spontaneity. The blue star that became the Eater of Souls wanted to fill the whole universe with his song, to create eternal monotony. The Eater is therefore a powerful force for order and control. Perhaps its presence is what attracted such a mighty entity of chaos to Equestria in the first place. But the Eater was dormant, so Discord's chaos was too much; it destroyed the order necessary to live happily in Equestria, and he had to be rendered dormant as well. Once the Eater of Souls crosses the Godzilla Threshold, releasing Discord to fight it may become a viable option!
The reason Psycoshy can't access EC-1101 is that she is Goldenblood's daughter.While Sanguine assumed Psycoshy would be able to access EC-1101 due to her mother being Fluttershy. Because of Goldenblood's treason, his descendants may have been actively been banned from accessing EC-1101. Sanguine may even know of this ban, however he is unaware that Goldenblood is her father.
Blackjack becomes the Bearer of GenerosityThe origional Fallout: Equestria has assigned each other Element, and at this point Blackjack has completely devoted herself to 'doing better' as well as suffering massive injuries. She still cannot stop helping ponys.
Lacunae will be the alicorn that helps save Littlepip after Maripony.This one's really just a hunch, I don't have any evidence for it. Although it would help Lacunae ( or at least the piece of Twilight inside her) to get a little closure.
Octavia's contrabass is a soul jar.Blackjack got it after she delivered the letter to Octavia's body. She's the only one that can play it, and it's always perfectly in tune. It occasionally moves on its own. And last, but not least, it blocked bullets without a scratch.
Black Jack's real talent is Winning Against the Odds.Not only in games. In real life. The best bet for her is always risk everything. And, when she finds out? Game Breaker...
Blackjacks MM blood comes not from Twilight, Rarity, or Fluttershy, but from...Pinkie Pie. Morale has barly been mentioned at all, and considering her ability to ignore horrible, horrible things and her ability to make friends easly, it makes more sense than the other options.
The Angel of Death isn't like the other souls in Rampage.Here's another wild theory. After capturing the Ao D, Mo M officials (read: Pinkie) declared that, "she’s an evil, wicked, no good, very baaaaaad pony, and we’re going to make sure that she can’t do it any more!" Suppose that Officer Softheart was dying from her injuries and not even the Mo P could do anything to stop it. So instead, they decide to rip out all the Angel's memories and install Softheart's in their place, giving Softheart a new lease on life in the body of the killer she apprehended. They do reconstructive surgery to give the ex-Angel Softheart's face, and send her home with a clean bill of health. And then the dreams begin.
Mr. Horse made a pact with the Eater of Souls.The Eater of Souls is the ideology that drives the Harbingers (with their one-note song). However, I find it hard to believe that the Eater of Souls can directly influence magic and technology without a pony as it's agent (there's no precedent in Fo E canon, IMO). Since Mr. Horse is based off of Mr. House, it isn't much of a stretch to think that he plugged himself into some sort of computer (it's even hinted that he may have tried to duplicate a Crusader Maneframe). Who better to run the factories that supply the Harbingers? Mr. Horse gets to live, and the Eater of Souls spreads its malevolent song across Equestria. Hoofington Rises!
The first stallion Blackjack took for retirement was her father.BJ often thinks back to the first stallion she took to Medical for retirement, particularly noting his red-and-white-striped mane and how polite he was with her.
Project Horizons is Goldenblood's plan to Colony Drop the moon onto HoofingtonIn chapter 53 he asked Trottenheimer what would happen if they combined 10,000 tonnes of moonstone with the optimal ratio of starmetal. Answer: nothing lives. I'll admit the why has me stumped.
Goldenblood survived his execution and might even still be aliveIn chapter 55 we get photographic evidence of his death. He was burned to death with dragonfire. Spike's dragonfire, to be exact. Goldenblood is simply too much of a Magnificent Bastard to not find some way out of that.
The attack used in chapter 26 was an offensive use of Alien Geometries"Two more floated into view, and from the horn of the first a line of distortion wavered through the air and swept across the passage. It had absolutely no effect on the walls, my barding, or my flesh. It did, however, shatter every bone in my legs as it passed through me." If you make space non-euclidean, it will distort the light that passes through it, since the space itself is distorted. Anything flexible will be fine, but anything inflexible will break under the fact that it was built on the principle that the angles on a triangle no longer add up to 180 degrees, and this principle no longer applies. This is analogous to how you could (sort of) flatten a disk of cloth onto a sphere, but trying it with something rigid isn't going work. That does raise the question of why it didn't destroy the walls. My guess is that it just didn't have enough power, and the spell fizzled out rather than shatter the walls as it should have.
Blackjack is pregnantWhich is why Pinkie said "congratulations" in the memory orb.
Most of the characters have low luck statsI mean, just look at what happens to them, and the frequency of said "what"s.
