In the ancient castle ruins of the royal pony sisters, deep within the Everfree Forest...

Nightmare Moon: [laughter] You little foal! Thinking you could defeat me? Now you will never see your princess, or your sun! The night will last forever!
[All five ponies talking over each other: Pinkie Pie: Don't worry Twilight, we're here. Applejack: Don't worry, we'll be there.]Twilight Sparkle: [gasp] You think you can destroy The Elements of Harmony just like that? Well, you're wrong, because the spirits of The Elements of Harmony are right here.
Nightmare Moon: What?
Twilight Sparkle: Applejack, who reassured me when I was in doubt, represents the spirit of... honesty!
Twilight Sparkle: Fluttershy, who tamed the manticore with her compassion, represents the spirit of... kindness!
Twilight Sparkle: Pinkie Pie, who banished fear by giggling in the face of danger, represents the spirit of... laughter!
Twilight Sparkle: Rarity, who calmed a sorrowful serpent with a meaningful gift represents the spirit of... generosity!
Twilight Sparkle: And Rainbow Dash, who could not abandon her friends for her own heart's desire represents the spirit of... loyalty!
Twilight Sparkle: The spirits of these five ponies got us through every challenge you threw at us.
Nightmare Moon: You still don't have the sixth Element! The spark didn't work!
Twilight Sparkle: But it did! A different kind of spark. I felt it the very moment I realized how happy I was to hear you, to see you, how much I cared about you.

[Dark smoke encircles Twilight Sparkle, until she is completely out of sight]

Nightmare Moon: NOOO! Nooo!

[An explosion! Twilight Sparkle is thrown out of the smoke and onto the ground. Her head bends at an unnatural angle. The other ponies rush towards her]

Nightmare Moon: You little foal! Did you think that I would allow you to trap me again for another thousand years of pain and loneliness? Did you really believe that you could defeat ME?

[Fluttershy starts crying over Twilight Sparkle's corpse. Rarity, Applejack, Rainbow Dash, and Pinkie Pie raise their heads and stare at Nightmare Moon with hatred in their eyes.]

[Ponies talking over each other: Pinkie Pie: You! ….You, bad person! Applejack: I'm gonna take you to town and make a new coat outta you! Rarity: I will see you destroyed! Rainbow Dash: I'll beat you black and blue so fast you won't even know what happened to you!]

Nightmare Moon: ahahahaAHAHAHAHAHAHAHAHAHAH!

[Dark smoke again begins to build in the castle room]

Nightmare Moon: Do you really think you can beat me? Leave, and I may allow you to live.

[A fight ensues]

Rarity: Her magic! It's too strong! She counters everything I try to do!

Rainbow Dash: How is she so fast? It doesn't make sense!

Applejack: Keep her still for a mite Rarity, that's all I ask! Gimme a chance to knock the living bejeezus out of her!

[Another explosion, this time the castle walls are destroyed]

Nightmare Moon: AHAHAHAHAHAHAHAHAHAH!

[Rarity, Applejack, Rainbow dash, and Pinkie Pie are sprawled on the ground]

Nightmare Moon: Now nothing can stop nighttime eternal!
