"Spike is in Canterlot on royal business. I'm home all alone tonight. *Gasp* You and Applejack should totally sleep over! We'll have a slumber party! I've always wanted one of those!"

The spark ignited inside me when I realized that you all... are my friends! You see, Nightmare Moon, when those Elements are ignited by the... the spark, that resides in the heart of us all, it creates the sixth element: the element of... magic!"
