Ok Equestria Girls Special Idea!
(This is the aftermath of listening to we will stan for everfree in loop and imagining Spitfire singing it):
Ok so it's kinda like the plot of legend of everfree, the mane 7 discover that flash it's related to Spitfire who is known to be the youngest capitan of the wonderbolts, a soccer team whom Rainbow it's a big fan of (she's literally they're age so 16/17). So the mane 7 + tgbg goes at the wonderbolts HQ where the wonderbolts basically tries to give soarin and rainbow a date (w/o knowing that they were already dating bc they're dumbasses), rarity it's in a competition with Misty Fly to see which one of them it's more fashionable and other shenanigans happens. Sunset notices that Spitfire it's acting strange and she discovers that Spitfire it's in debt bc she ran away from her house bc it was very abusive and she can loose the 'bolts due of this debt so she uses equestria magic and tipycal eqg shenanigans happens and everything it's cool.
