Since you've come to Ponyville, you've displayed the charity, compassion, devotion, integrity, optimism, and of course, the leadership of a true princess.
But... does this mean I won't be your student anymore?
Princess Celestia
Not in the same way as before. I'll still be here to help and guide you, but we're all your students now, too. You are an inspiration to us all, Twilight.

[voiceover] Are you talking about Twilight? I can't see what you're thinking about.
Princess Celestia
[voiceover] Yes, Spike. I was constantly surprised and impressed with her discoveries. But I noticed that her pursuit of academia was preventing her from reaching her full potential.
The students left us notes before they disappeared. When the school closed, they didn't want to say goodbye to each other. They claim they ran away to stay together.
The students couldn't have done this by themselves. Some creature is hiding them! If the niece of our queen is not found soon, I promise there will be retribution!
