My Little Pony: Friendship is Magic, Season 5

Twilight:
Obviously, the long-term effects of the simultaneous acquisition of cutie marks has yet to be determined, but... [sips water] Next slide, please?

[Long pause, Moondancer wakes Spike, who provides the slides]

Twilight:
I can speak from my own experience that the power of cutie mark magic is very real. And in the instance of my friends and I, it can be traced to a single event. Without Rainbow Dash’s race to defend Fluttershy’s honor, this Rainboom wouldn’t have happened. Fluttershy might never have discovered her love of animals...Applejack might never have realized that she belonged on her farm... And Pinkie might never have decided to leave hers. It might be hard to imagine Rarity without her sense of fabulousness, but it’s even harder to fathom what my life would be like. without this Rainboom, I might not have gotten into magic school, Celestia wouldn’t have taken me on as her pupil, or sent me to Ponyville to meet my friends. And the most powerful thing about cutie mark magic that I’ve found is the connection I share with them.

[She stops as she notices Starlight in the audience; she looks around, but she has vanished]

Twilight:
But...um...the real question about cutie mark magic is who it seems to affect.
