Okay, here’s two controversy-laden ideas to smack you with.
The first is Scootaloo playing with a large dog. It seems fairly mundane at first, until she and the dog are chased into the everfree forest by burly ponies in white coats. There, the dog defends her from timberwovles, and eventually decides to return to Ponyville, giving up Scoots and going away with the nice ponies. The Twist is that the dog is actually Screwloose, the double twist being that she’s her mom as well.
It’s my way of pushing Headcanon.
The second I just have no faith in my ability to write. It’s about Apple Bloom getting her mark at last in inventing, and against her family’s wishes, setting off with Flim and Flam, who promise they can teach her to harness her new ability.
The controversy in this one is her falling for the wiles and charm of Flim, eventually pursuing him romantically. Which is unfortunate for him, because he doesn’t cotton to relations with little fillies and believes his brother would hang him out to dry if he thought he was gettin’ funny with their third addition.
I know I would get alot of crap for just suggesting a story like that, but I think it would be a hit if written successfully.
