Rarity loves to hold her head up high and put on a strong face, smiling for the world to represent the fashions she designs. But what if behind that smile she's hiding something, a weakness and deep seated self-loathing for instance? Would this loathing go deep that it'd invert her very soul and come out as a similarly, struggling one, even across a different universe? More of a simple dramatic exploration enacted out of possible emotional depth between two characters than a real story.
Inspired a bit by David Lynch's Lost Highway.
Also because I like Transformations without explanations.
