** In chapter 12, Mabel tries to rationalize Dipper's accusations on her selfish, controlling, and occasionally hurtful behavior with this: "Dipper, I, you... I realize I haven't been kind about it, but it's not that I don't love you for who you are, I just want my brother to be happy! You could lay alone in bed, completely away from anything or anyone that could possibly trouble you, and think yourself into a fit over nothing! '''I just wanted my brother to be happy, and the number one person who always made you unhappy was you!"''' ''This'' is probably how Mabel rationalized her parents' favoritism towards herself and emotional abuse towards Dipper. Mabel saw how they treated Dipper and attempted to figure out ''why'' her loving parents would be dismissive of Dipper's thoughts and emotions but not hers. In the manner that children who are shown love by their parents tend to trust their parents, Mabel heard her parents' teaching that "as long as you are happy, Dipper will be happy" and concluded that ''the problem was Dipper,'' that they decided to treat Dipper this way because Dipper couldn't be trusted to make himself happy, and therefore couldn't be trusted to make decision that would make himself happy--''and thus, his judgement was questionable, '''period.''''' After all, why else would her parents ignore his feelings and opinions and criticize him for harmless personal choices so much? Mabel loves her brother, but she naturally rationalized her parents' favoritism towards her and emotional abuse towards Dipper by trusting her parents' judgement of the situation and therefore dismissing Dipper's upset and resulting insecurities and anxiety as signs that he was the problem, not them. This further adds to the reasons behind her struggle to accept that Dipper is genuinely happier in Gravity Falls with all the greater independence and autonomy that that entails, because Dipper's away from the family members who, in Mabel's mind, knew more about what was best for Dipper than Dipper himself did. In Mabel's mind, it's not that Dipper was raised in a hypercritical environment that made him feel ashamed of being himself, no, ''Dipper'' was the sole cause of his own unhappiness and Mabel's and their parents' actions were all just genuine attempts to help him, so how could he possibly be happy without them? This conclusion is reinforced by the fact that Mabel eventually realizes that she's never actually bothered to learn Dipper's reasons for any of his personal choices and the only explanations she can think of for why he has different opinions than her is that his judgement is stupid and inferior. Mabel wasn't really taught to think of her brother as an equally human being, with equally complex and valid emotions and reasons behind his decisions, and therefore never saw discarding Dipper's opinions as morally wrong. All of this adds up to Mabel having internalized and replicated the idea implied by her parents' treatment of Dipper: the idea that Dipper is ''less'' than Mabel--less lovable, less capable, less complicated, less understandable, less pleasant to be around, less sound of judgement, less capable of managing his own life without freaking out. [[FreudianExcuse And if Mabel's so much better than him at judging what's best, and Dipper can't even be trusted to make himself happy, why would it be wrong if Mabel stepped in and decided things for him?]] Really puts a different context on Dipper's insistence that the problem in their relationship is Mabel's inability to trust him.

* The mine collapse. Historically, it's relatively common for not all of the mine shaft and branching tunnels to collapse, meaning some miners can and have historically survived intial mine collapses but wound up trapped underground. Since the girls decided to keep the mine collapse a secret to avoid responsibility, no rescue attempt was dispatched from town. Unless the decidedly unscrupulous mining company noticed the disaster in a timely manner and was willing to send a rescue, the girls' decision to keep quiet will have doomed any survivors. Dying from being trapped in a dark, small, airless place with no one to rescue you is, to put it mildly, the stuff nightmares are made of. And the manotaurs had warmly greeted the girls as their ''friends.''

* Mabel's line, "So you're helping Dippen-Dots out with all his research huh? What's he got you doing, running on a hamster wheel to power the laboratory, or are you testing new cosmetics out before they move to animal testing?" is a simple couple of insults on the surface, but so viciously insulting when you break it down that it's practically RefugeInAudacity, especially when said in front of two people who are ''deeply involved in scientific development.'' The first implies Pacifica's as useful to Dipper's and Ford's research as an animal, but the second, far more clever insult implies she has less worth than one, because in traditional (and increasingly controversial) cosmetic production, animal testing is done before products are tested on humans in order to screen for possible harmful side effects and reduce the chances of accidentally harming humans. By suggesting Pacifica would be a test subject before production moved onto animals, Mabel's basically calling Pacifica not only sub-human, but sub-''animal.'' All while deliberately using her InnocentlyInsensitive tendencies to disguise these incredibly insulting statements as attempts at jokes to Pacifica look like an over-reacting "bad guy" in the conversation if she takes offense. It seems on the surface that Pacifica's largely unaffected by these stunningly nasty insults that appear to come from nowhere, but on a second read-through Pacifica almost certainly saw through Mabel's intentions and Mabel's insults probably helped set the tone for the tongue lashing Pacifica gives her later.

* Unless something miraculous were to happen to spare them, most of the characters we meet in Mewni, good, bad, Mewman, "monster," and other alike, are fated to become victims of their own Weirdmageddon and absorbed by and destroyed along with the Nightmare Realm. We know at least some of the main Butterflies survive because the family is mentioned as being part of the DistantFinale, but we also know that they were able to flee to Earth at the beginning when the Dimension was first overrun and the Portal isn't very usable afterwards due to Bill's spying, so we have no knowledge of if being left behind and trapped on Mewni is survivable and a large-scale rescue mission to bring refugees to Earth before their dimension is erased along with the Nightmare Realm is not likely. While it's feasible that some populations may have survived in the few salveagble scraps of Mewni that were bolted onto the Earth dimension in the aftermath, the vast majority of everyone else in the entire dimension of Mewni are most likely doomed to be erased from existence very soon and very horribly.

* The SharedUniverse created by this AU fanfic primarily centers on people and places from Disney produced, original series animation from the 2010's for the first two-thirds of its content, but in only outlined last third of the story the cast would have been swept into a space opera-esque scenario split between two warring "alien" empires, the [[Creator/Nickelodeon Irkens]] vs [[Creator/CartoonNetwork Gemkind.]]
