An alternate ending to "Luna Eclipsed", where Luna connects with the citizens of Ponyville in a different way, and truly captures their hearts and emotions.
I personally hated Pinkie Pie for what she did to Luna, and I will NEVER forgive her for what she did. This seems like a better way for Pinkie to face what she did, as well for the ponies of Ponyville to truly see what Luna deeply desires in her heart. Truly touching if you ask me.
