When 5 ponies continue their work, they realize the fatal truth. Why wasn't their talents achievable for them anymore? Imagine being able to do something and having that ripped away from you, you are no longer good at what you deemed your life, what you spent your time with. No mater if it's something large like tailoring or something for comfort liking making others happy we're all good at something. Imagine suddenly being good at something you don't care for. Something. Your destiny has changed.
