Thank you for the question, but I’m afraid you have a different head-canon than mine, and that’s okay. Here’s some of my reasoning for how I’ve written the characters so far.
Scootaloo’s parents have not been confirmed by show staff or writers up to this point. While I am taking the characters and world in a different direction that the original writers did not intend, it is heavily based on the original storyline and worldbuilding that Hasbro/DHX has done. I have added a little of my own, in regards to Changeling behavior, cryptozoology, and physiongomy, but otherwise my intentions in the blog have been to make logical extrapolations of possible behavioral shifts in characters. For example, Twilight’s need to monitor the world was based off of S2 E1 as well as the entire Wedding arc. Fluttershy’s usage of antianxyalitics (and subsequent overdose) were based off of extrapolations on her behaviors and cofirmed when the character mentioned that she had social anxiety. This is coupled with my own experiences of being on antianxyalitics and accidental overdose. Scootaloo’s stalking behavior is based off of her apparent need for affection, with Rainbow Dash as a surrogate sister in her mind. This is exacerbated by Twilight needing someone small and athletic that can put recording devices in unexpected and covert areas. Again, as of yet, Scootaloo’s parents have not been introduced nor their occupations made known. I have taken the liberty of creating my own head-canon, much like you have your own, though mine gives a nod to popular culture rather than recycling old characters, which is more in keeping with the writing styles of the show authors, along with tying them in with existing episodes, though not in a directly visible manner. In this same vein, we may see rise of a radio station with odd broadcasts, hosted by a character named Cecil who is very close friends with a pony named Carlos, who is a scientist. Who knows. I’ve also taken the liberty of adding in new characters that do not and could not exist within the constraints of family-friendly TV censors, because their story arc would be determined as “too frightening” and how I plan on rendering some of the art as “shocking” to children. They are there to keep the story fresh and away from being centered on one character specifically, as well as to expand and explore world lore from a firsthand experience.
There is reasoning beyond this as to why I did not make Scootaloo’s parents special forces, military, sneaky, etc. This will become apparent near the end of the blog’s current story arc. I apologize for the slow update speed, but I have a lot of projects going on as well as college classes. Just please be patient - the story is going to continue until the end. I have no intents of dropping it until it is finished.
