FoE quote

“You’re not unimportant, Littlepip. You’re the most important part. I told you that your group wasn’t the one that was needed because it was obvious to me that you and SteelHooves weren’t ever going to be Bearers But it takes more than just being loyal or honest to be a Bearer just like it doesn’t require that the Bearers be perfect paragons of their Virtue. There’s more to it than that. I mean, it’s not like the ‘destined few’ just happened to all live in Ponyville. Fluttershy, Applejack, Rarity... I’m sure there were plenty of ponies with the same virtues, but it wasn’t enough to just have the virtues. That wasn’t what made them suitable to be Bearers. It was only when they accepted the call to act, and became friends in the process, that they became worthy in the eyes of the Elements.”
