The moon has risen over Equestria. A winged pony looks at the moon, studying it carefully. Another, slightly older, watches it as well. The pony walks up to the older pony, shivering.
"What are you doing here?" asks the older of the two.
"I'm scared." says the younger, helplessly.
"What are you scared of?"
"Night Mare Moon."
"Don't be silly. Night Mare Moon is gone. You of all ponies should know that. The Elements of Harmony brought back the wonderful Princess Luna. Night Mare Moon was no more after that night."
"That's the story, but I know it's not true. She's still in there, somewhere. And she will take over Equestria again."
"You're wrong, dear. You worry too much. I watch you, and all you do is worry. Night Mare Moon will never harm our land again. I can protect you."
"No, you can't." replies the younger pony quickly. "I surely would like to think you can, and so could you. But remember how powerful she became last time!" she pauses and looks down. "I can't protect myself either. Nopony can. She's still out there, plotting and scheming. You and I can't just stop that. I know she is inside the 'glorious Princess Luna', no matter what anypony does!"
"The Elements of Harmony were stronger than Night Mare Moon last time. Surely they will be again, if anything happens. Which will not, because the Elements' effects are permanent." the older pony tells the younger.
"I know that isn't true. Remember what Discord did?"
"What Discord did was extremely rare."
"So? It still happened. And if Night Mare Moon finds her way out of- out of wherever she's been cast- I'll be helpless. We'll all be helpless. Ever single pony in Equestria, Elements or no Elements!"
"Night Mare Moon was just a personality- a state of mind. We now have a perfectly stable princess of the night."
The childlike pony's eyes narrow. "Stable? Are you bucking kidding me? STABLE? How stable would you be, trapped on the moon for a thousand years? That's ridiculous! More like weak, confused, prone to any state of mind!"
"I'm sorry. I didn't mean-"
"Night Mare Moon is still very real. The sooner you learn that, the more we can prepare."
"Okay. So maybe I shouldn't have said stable. I meant to say strong. Powerful, and able to keep Night Mare Moon out."
To this, the young pony says nothing.
"If you ever have any other concerns, please come to me." concludes the elder pony.
"I will."
"Good night, Luna."
"And to you, Celestia."
