Twilight gasped excitedly, biting her lip to contain her wide smile as she read the piece of paper that she held.

"Look, Spike!" Twilight exclaimed, pushing the letter towards his face. He began reading.

"Dearest Twilight,
My cousin, Rain Peak, is coming to stay in Ponyville for the time being. Since you are such a loyal and hard working student, I think you are ready to be a tutor to one of my less advanced students. So I would like to assign you to my hard-working cousin. He'll be arriving later tonight. He is currently staying with the Apple Family at Sweet Apple Acres, so please meet with him as soon as you can. He has recently become interested in working in my palace, so he needs a full education.
Sincerly,
Celestia" Twilight squealed happily.

"SPIKE!" She exclaimed. "Celestia wants ME to tutor HER cousin!" She broke into a smile so wide that Spike thought her face might split in two. Spike returned the grin, patting her on the back,

"Congratulations, Twi! You've finally got what you've been hoping for!" Twilight was breathing quickly, not even attempting to contain her excitement.

"She called me advanced! Do you know what this means?!" She swiveled suddenly to face Spike,

"That means I've got to do a quick, basic review of everything I've ever learned so that I can be ready to tutor Rain Peak." She began pacing, "Perhaps I should start with the elements of Harmony? No...to showy. How about Discord? Or maybe I could teach him about the Chrystal Empire! Or-" She was cut off by Spike,

"Twilight! Focus! You know, we haven't even met him yet! We don't know what he needs to learn."
He trotted over and snatched the book she had set on the table out of her hooves, "Twi, you know too much already. The best thing you can do to prepare for your new student is rest." He nodded towards the stairs, where her comfy bed awaited.

"Sleep?!" She squeaked, "How could I sleep at a time like this? I've got to do SOMETHING..." She glanced around. "Oh! I need to write back to Princess Celestia! She grabbed a quill and dipped it neatly into her jar of ink, writing.

Dear Very most Honored, royal, kind Princess Celest-

"Really, Twi?" Spike stopped her. "Just address her normally, you sound like you're bribing her." He giggled. Twilight bit her lip,
"You're right." She scribbled out her former greeting, placing a new, clean paper in front of her.

Dear Princess Celestia,

Thank you so much for this amazing opportunity! I promise I won't let you down. I'll teach your cousin everything there is to know and more! I will make sure that he enjoys his time here and becomes one of the most educated ponies in Equestria.

Your Faithful Student,
Twilight Sparkle

Spike nodded his approval from over her shoulder, picking it up,

"Do you want me to send it now?" Twilight nodded enthusiastically, "Okie dokie." He stated as he breathed a flaming ball that consumed the letter.
