Luna has a secret.

A secret that she's kept close to her heart ever since her return from the moon, a secret she's hidden for so long that she's no longer even sure if it's real.

Night One

"Why is she standing out there? What does she want?"

Night Two

"There's something off about her...."

Night Three

"That's not Fluttershy..."
