“How did this happen, and how do I make it unhappen?”

Dear Twilight,
 
Luna and I are on vacation in the Griffon Kingdom. Your chariot will  
arrive in 30 minutes and the  
Royal Regalia is in the wardrobe in my  
Bedroom. The key to it is attached to  
this letter, make yourself at home  
while you stay in Canterlot.
 
I will see you in two weeks my faithful  
Student.
 
Sincerely,  
Princess Celestia

Yer regalia doesn’t even fit yet, Sugarcube.

“I’ve made a terrible mistake.”

…Now what the fuck do i do?
