I have an idea for a fanfiction that is set shortly after the episode where the Cutie Mark Crusaders get their cutie marks, and is meant to be like this universe's equivalent to a school shooting. I'm thinking of making this into something that could plausibly work in the show's universe (not some sort of ludicrously balls-to-the-wall gorefic like Cupcakes).
The story begins when the unicorn foals are doing some magic lessons at school (led by Princess Twilight?). However, Dinky (aka the little background unicorn filly with the gray body and blonde mane) is having more difficulty with the spells than the rest of the class. Diamond Tiara tries to be a leader and help her at first, but Dinky (and maybe some of the other foals in the class, including the "freak" ones she called out during that particular episode?) still don't fully trust her even after she's been redeemed. DT tries to still help Dinky, but quickly gets frustrated and slips back into being a bully, saying that Dinky can't do magic because she's "broken" just like her mother Derpy, which has a more negative impact on the young unicorn's self-esteem. The CMC's call Diamond Tiara out on her behavior and try to remind her of the true meaning of her cutie mark, but their words fall on deaf ears.
The bullying eventually escalates over time to the point where one day, Diamond Tiara has Dinky backed into a corner, surrounded by all the other foals in the class. The CMC's are at the back of the crowd and can't really see what's going on. Cheerilee tries to control her students but is unable to. Suddenly, Dinky starts involuntarily glowing with magic energy, causing the crowd of foals to get scared and run away from her. Diamond Tiara tries to run at the last minute but is hit full-on by Dinky's magic blast, causing her to be seriously injured and sent to the hospital, where she'll be mostly incapacitated until near the ending.
After this, Diamond Tiara's parents (primarily her mother Spoiled Rich) accuse Dinky of intentionally hurting their daughter and say that she's too dangerous to be around other foals. Some of the adult ponies in town have already questioned Derpy's parenting abilities prior to the incident, and have now fully turned on her after the event. Although Derpy works hard to provide everything that her daughter needs, Dinky still feels like their situation is entirely her fault. Which means taking her away would be even worse for Dinky, especially because she’d blame herself. Now that the adult citizens of Ponyville are pushing for the pony equivalent of Child Protective Services to get Dinky taken away from her mother, believing that she's unfit to raise the young filly, who should be sent to some sort of juvenile detention facility. It seems as if the situation has now become hopeless and no resolution is in sight for the struggling mother and daughter due to this string of unfortunate events.
But NOW it's up to Apple Bloom, Sweetie Belle and Scootaloo to get the truth out and set things right.
Since Twilight is a princess now, she and the rest of the M6 are seen as voices of authority, and so the town of Ponyville is looking to them for guidance on how to handle the situation. But they're conflicted over whether they should punish Derpy & Dinky or try to help them. This is where the CMC would step in, specifically telling how they personally relate to the situation and reminding their older sisters of the lessons about friendship that they learned from them based on their respective Elements of Harmony:
Apple Bloom has a quirky relative (Granny Smith) just like Dinky has with her mom. She reminds Applejack about how she taught her to always tell the truth no matter what, and encourage friends and family to do the same.
Sweetie Belle was also shy and has struggled with learning magic just like Dinky. She reminds Rarity about how she taught her to always give/do whatever she can to help out those in need.
Since Scootaloo can't fly, she relates to Dinky's (seeming?) inability to learn magic. She reminds Rainbow Dash about how she taught her to always stick up for a friend no matter what.
Diamond Tiara should get a redemption too. When the CMC's finally succeed in clearing Dinky's name, they call DT out for being a bully again despite having realized the true meaning of her cutie mark with their previous help. DT then owns up to her actions and apologizes to Dinky. Since Twilight is now the Princess of Friendship, she could give a speech at the end praising the CMC's for the work they did to support their friends. (I'm not sure how Pinkie and/or Fluttershy could play much of a significant role, or if they even should)
What do you guys think? Any ideas for a title, or more things to add to the plot? Anyone interested in helping me write this?
