"Uugh, seriously? I figured out this 'Rainbow Factory' story was just made up to scare pegasi fillies to behave a long time ago."
"I have to admit, Scoots, that author really did a terrible job trying to give your hero Rainbow Dash a bad name, making her go out of character like that, even more than that one story where Pinkie goes bananas and killed other ponies."
"Well, at leas' this Rainbow Dash ain't as horrible as how tha' meanie tha' wrote 'Sweet Apple Massacre' made mah big brothah to be."
And what's scary is this one guy is a 'reconstruction' of Rainbow Factory that was just as bloody and tragic, but managed to supposedly keep RD IN CHARACTER as she pushes pegasi foals to their deaths.
Then there was the fanfic that held MUCH MORE power. That Rainbow Factory was a brain damaged DELUSION of Rainbow Dash's brought on by a combined foalhood trauma and repeated use of her Sonic Rainboom without protection. Where the doctors have to tell her during her delusional periods to 'resume her cover job.'
Yeah, read them. Bright Eyes, or rather her G3 self, managed to save the Breezies from Discord's curse! And then there's the part before where she survived being driven to utter despair by none less than the Mother-End-Of-All-Things herself! What's next?
Oh, I could easily see Discord doing something like that to prank Twilight. Like altering a book so that it doesn't cause one to learn, turning Twilight into a bimbo to stop her from interferring again, that is if he hadn't turned good anyways. But I could so see him trying to reverse laws of physics, like making books reduce intelligence instead of increase through study.
