"Goodness, we are in the presence of a very special pony today," Sunset announced excitedly, "Our very own Princess of the Night has taken time off royal duties for a special appearance of our show!"
"Please give it up for, Princess Luna!" Starlight introduced with equal enthusiasm.
"Thank you so much for coming on our show," Tempest thanked,
"'Tis a pleasure to be on thine show," Luna answered with her usually royal tone, "Hearing your show has sparked an interest, with me having a past not too dissimilar to you ponies in this room. My sister also encouraged me to take time off royal duties to come on with you."
"Many would remember you as Nightmare Moon," Starlight said with hesitation, "How would you describe that past?"
Luna sighed, "It is a moment of my life that I look back on with the most sincere regret. My Past is still there, etched in the pages of Equestria's long history, but I try my best to move forward in the best way I, both for myself and my subjects. Turning things around, starts by taking a step in the right direction."
"I imagine it took some time to adjust to modern times?" Trixie asked.
"Indeed," Luna said with some embarrassment, which was quite unlike her, "Although the main challenge was getting subjects to see me beyond my past. It didn't help on my first visit on Nightmare Night. I thought the scaring was because of my past, but it was just that ponies just liked to be scared. Pinkie Pie the most."
"Pinkie being Pinkie," Starlight rolled her eyes at that.
"My old self is still there, and I still get jealous about my sister's accomplishments. But I remember that my duty is just as important as my sister. Thanks to you Starlight, my sister and I have seen each other in a different light. How hard we work to keep our subjects safe. To allows our ponies to go out in the sunlight and sleep peacefully in the moonlight," Luna recalled, earning a weak chuckle from Starlight.
"That says something from a former villain who switched the princesses' cutie marks," Starlight sighed, earning a surprised glance by the other unicorns in the room.
"You switched the princesses' cutie marks?! The actual princesses' cutie marks?!" Sunset cried out in surprise.
"Please," Starlight groaned, "You're starting to sound like Twilight, and it was a long story that I do not want to go through again."
"Regardless," Luna comforted her, "She managed to let us see each other in a different light. In addition, we still have a sisterly mockery with each other, much like any other sibling in Equestria."
In Canterlot Castle, her sister gave a hard glare at the radio. Her sister wouldn't. Would she?
"My sister has the most unfortunate sweet tooth, one to rival even Pinkie Pie," Luna chuckled, "It's lucky Cadance managed to save a picture of her stuffing her royal mouth with cake in the Foal Free Press. I have it framed in my royal bedchambers."
Celestia gave the radio a hot glare that could melt metal with her solar flares. Somepony is getting extra paperwork this evening.
"My sister also dreams of such desserts in her dreams," Luna continued, "I once peered into my dear sister's fantasies, and it was enough to make me horribly sick with how sugary her dream was. I can say it could rival even Pinkie Pie's sugary fantasies."
"Actually," Celestia said with a sigh, "Paperwork isn't going to be enough for this."
"Believe me," Sunset shivered, "That explains so much."
"Explains what?" Tempest asked with concern.
"You don't want to know," Sunset quickly quipped.
"The Great and Powerful Trixie agrees," Trixie also gave a shiver.
"No matter what world Pinkie is from," Sunset noted, "There is no escape from Pinkie's strange things."
"That I can agree on," Luna sighed.
"And on that note," Tempest quickly changed subject, "I think it is best to say that we call it a day before the very foundations of logic is shaken to it's core."
"Trixie agrees," Trixie nodded.
"Thank you so much for joining us on this very special guest visit," Starlight thanked the Princess.
"It was a pleasure to share my past and laughs with you all," Luna thanked the group.
The sun was setting when Luna got back from her interview. However, she was greeted by her sister with a menacing smile.
"Did you have a good time, dear sister?" Celestia said menacingly, "Because I remember a certain incident with you and the discovery of coffee..."
"By the moon..." Luna feared with wide eyes of pure horror
