The metal doors closed but Princess Luna´s doubt were still plenty.

"Dear Sister, I must insist. Twilight Sparkle is still not ready for such a task."

"Don´t take me for a fool Luna, I know Twilight will need help, that´s why I have a backup plan..." Celestia used her magic to lift the magic crystal which glowed and displayed and holographic images of dozens of ponies. "I have secret agents located in every town in Equestria, waiting for my signal to spring into action."

"I´m...impressed. When do you find the time to prepare all this, sister?"

"Ha, what did you think I spent the last thousand years doing Luna?"

"Mostly eating cake and playing childish pranks on your subjects..."

"Crystal, call agents Music and Candy!"

The picture of a green unicorn and an earth pony appeared with the words NOT AVAILABLE.

"What? Ugh I can´t believe those two...call agent codename Caramel"

The picture of a female earth pony appeared with the words NOT AVAILABLE.

"The flower trio?"

NOT AVAILABLE.

"Okay, which agents do I have available?"

The picture of a grey pegasus and a wine colored earth mare appeared.

"Bubbles and Grapes?"

"Don´t you mean Derpy Hooves and Berry Punch, sister?"

"Shhh we can´t use those names..."

"Your talent for melodramatic still remains after a thousand years sister..."

"Nevermind that! Send them to the Crystal Empire!"

Once the threat of King Sombra was defeated, agents Bubbles and Grapes returned to the castle.

"Tell me agents, how was your mission in the Crystal Kingdom?" Celestia looked at agent Grapes.

"....what? Ih yeah the HIC Crystal thinghie...it was fun! HIC I saw a jousting tournament and HIC hahaha flugelhorn..."

Celestia moved over to agent Bubbles. "....muffins!"

"...shut up, Luna."

"Yur pretty...auh, the floor is cold..."

"...MUFFINS!"
