This story is a sequel to The Right Place in the Wrong Time
Part of the "Royal-Tea" series. Princess Celestia has been your marefriend for a while now, though given her status, it is hard to find time to spend together in a public setting. Figuring that Nightmare Night is the perfect opportunity to do just that, you invite her to join you for a relaxing evening. She accepts, though an unfortunate encounter with "Nightmare Moon" may put a damper on your evening, as well as reveal some things that your royal companion would have rather kept buried.
This story takes place shortly before the start of season 5 of Friendship is Magic.
Between that season 4 finally and season 5 premiered, Equestria Girls Rainbow Rocks 🌈✨ has passed, right?
