I see that Luna wanted to take a little picture of herself as her nightmarish alter-ego. She even changed her phone's color to match.



Must been bored. Then Celestia go into the bathroom and... a awkward moment happened.



Celestia: Luna? Are you kidding me?

Luna: Uh... hey Tia! Well.... I got bored... and I got this very cool phone with this picture taking feature...

Celestia: You got freed of this prison of yourself and you still transform as her?

Luna: Well, they liked it when I scared them like that at last Nightmare Night.

Celestia: What? They... liked it?

Luna: Uh.... yes?

Celestia: Well, that explains it. But please Luna...

Luna: Yes? What is it sister?

Celestia: When you're done "picturing" yourself, change back before getting out or you'll get everypony panic.

Luna: Yeah.... that would be fun...

Celestia: Don't you dare!

Luna: Oh? And what would make you stop me? You can't send me back to the moon.... You c-can't r-right?

Celestia: Don't be stupid! You know very well that I wouldn't do that even if I could!

Luna: Pfew!

Celestia: However, I can still ground you and hide all your videogames for a month or two...

Luna: NO!!!! I'll be good.



Still the most beautiful MLP villain. Beautiful work
