• Entropy? Recessive genes? Mom cheated? Dad cheated?
-Lacks unicorn magic despite having horn
• Also lacks the magic inherent to all ponies
-HUGE, indecipherable cutiemark covering both flanks entirely as well as legs. Nothing happened to earn it, it just grew overnight for no reason
• No pony has ever seen a human, not even in myths, so there's genuinely no way to explain it
• Questions about it get reacted to exactly like the postal 2 petition
-Lifes quest is centered upon learning it's true meaning
• The seeking of this answer being the ponys life purpose which is the reason a cutie mark appears in the first place creates a perfect spiral down, however the pony is far too dim to understand that and thus will never know peace, creating another cementing factor in the purely confusing meaning of the cutiemark
