History Fridge / ScoobyDooMysteryIncorporated

* In "All Fear the Freak", we learn that two years before Fred was born, Mayor Jones was a college student, and WordOfGod says that he later became a college instructor for a while. And given that in "A Haunting In Crystal Cove", it's never outright stated that Fred's [[spoiler:fake]] mother was also Mayor Jones's ex-wife and it's also suggested that she ran off. So, from an outside standpoint (i.e. the general public), a [[GettingCrapPastTheRadar rather adult implication]] is that [[HeroicBastard Fred was conceived from pre-marital sex]]. And considering no one had seen Jones hanging around with a lady friend the past nine months prior to him having Fred (unless he already kept details of his personal life under wraps, since he's also shown to be a private individual), that also implies it was a one-night stand or a brief fling. It also looks rather interesting if he was still a college student or instructor when it happened.

* The reason that people do criminal activities in costumes in Crystal Cove is because that they won't get caught by the police because they support the tourism.

* It was baffling that the gang STILL can't figure out that the "monsters" are people in costumes (usually). After watching episode 11, realization came that they have these beliefs because the adults of the town also share the same ideas, given that Crystal Cove is titled "the most haunted place on earth." There's also the fact the monsters in this series are the most realistic to date. The guys making suits in this one are frighteningly good at it. They also tend to be ''much'' more violently-destructive than in previous series, meaning that even if they '''are''' suspected of being fake, they're still plenty ''dangerous'' and merit running away from.

* In "Wrath of the Krampus", since it gets explained that Mayor Nettles went to the prison herself to recruit Mary Ann into the scheme, it makes sense that she probably talked to ex-Mayor Jones to recruit him, since Fred implies that the gang weren't the ones that talked to him. Of course, Fred can't bring himself to talk to 'his father' right now, Shaggy sucks at talking to people, the rest of Mystery Incorporated always thought he was obnoxious, and Sheriff Stone probably can't bring himself to talk to his criminal boss either. Mayor Nettles was probably the best person to talk to him, since they can't riff on each other besides being each others' replacements and she's smart enough to know how to persuade him (i.e. something like "''Fred'' told me I could trust you, and now I'm not so sure.", implying that Fred still loves him, though an alternative interpretation that he won't consider is that Fred knows how greedy he is). Like him, she's a politician, after all. They speak the same language.

* Thanks to [[spoiler:the Nibiru Entity's malign influence]], Scooby's predecessors within the various Mystery Gangs have a long history of [[spoiler: betraying their human companions]] out of uncontrolled greed for [[spoiler:the Disc pieces and/or]] treasure. Scooby-Doo ''seems'' to be entirely immune to this effect... except that he ''does'' have greed as one of his most salient traits, not just in this series but throughout the franchise. It's just that in ''his'' case, it's greed for '''food''', not wealth. The freakin' [[spoiler: Nibiru Entity]] aimed its mind-corrupting powers at his dog-brain's "want-stuff" neurons, but hit his "want-food" neurons by accident!

* Brad and Judy having [[spoiler:Fred]] two years after they left Crystal Cove at the age when they could have been in college or possibly could have ''still been in high school'' sounds like something you'd hear in a movie about teens or young adults with miserable lives leaving their home to try to figure things out on their own, which makes this another play on the teen genre that ''Mystery Incorporated'' keeps poking at.

** While loyalty itself is pure, it can also be an example of PureIsNotGood, if the loyalty is for the wrong being, and a Scooby loyal to the Entity, rather than people or animals tempted by power, is a FridgeHorror unto itself. And there was a point in time where Scooby's own loyalty was wavering, when Shaggy was having his FriendOrLoverDecision and ticking off both Scooby and Velma. This is pure speculation, but if Shaggy had chosen Velma, the Entity might have been able to waver Scooby to his side and caused the apocalypse earlier.

** Considering that Mystery, Inc. have had some cases of the culprit's costume being destroyed and that museum exhibits can have representations of an object rather than the real thing, it's possible that the exhibit of Charlie at the museum is just a wax dummy or something similar bearing his likeness.

* After Scooby's AllJustADream episode, [[WesternAnimation/TheFlintstones Pebbles and Bam-Bam]] (somehow) making a cameo in the Man-Crab episode, the WesternAnimation/JonnyQuest gang making a few small appearances, and finally BlueFalconAndDynomutt guest-staring, it looks as though show isn't just a modernized reboot of the Scooby-Doo franchise, it's a modernized reboot of Hanna-Barbera itself!

* With the reveal of [[spoiler:The Evil Entity corrupting everyone close to the gang, as well as their predescessors]], Scrappy and Flim-Flam's presence in the spook museum. Considering Flim-Flam is a pre-teen con artist, while Scrappy is an over-achieving BoisterousWeakling, they'd probably give Mystery Inc. more to deal with besides the treasure. [[spoiler: The Entity probably corrupted these two and ruined their relationship with the gang(and by extension their cousins) to keep them out of the way.]]

* Of course Mayor Jones lets folks dress as monsters and run around doing illegal/morally suspect schemes. It's something he's done himself.

* A common criticism towards the show is the CharacterDerailment[=/=]CharacterExaggeration of the characters, especially the gang. Considering their world is a [[CrapsackWorld crapsack one]], they're a product of their environment that will continue to cycle. And as the show reveals more of its plot, it turns out [[TheCorrupter an Evil Entity]] has been influencing the events of the show this entire time. Previous mystery-solving groups have broken apart and failed because of their growing insanity from this Entity, and Daphne even explicitly wonders out loud after this revelation if any of them would even be friends without the Entity choosing them to be [[TheChosenOne the chosen ones]]. [[spoiler:This becomes ironic in the new universe when the gang are still friends with each other and with numerous other characters (and with better relations this time), most of the characters don't seem to have any mental problems in this world, and a common theory about the new universe is that [[AscendedToAHigherPlaneOfExistence Nova]] was the one who made it happen.]]

She's a politician, after all.
* In the series finale, we learn that [[spoiler: Brad and Judy became ''obstetricians'' rather than trap-makers. This isn't as random as it might seem: traps are what you use to ''catch'' something, after all, and a [[SelfDeprecation mildly self-mocking term]] used by some obstetricians to describe their duty is "baby catcher".]]
