Celestial School of Spellcasting, Unicorn Dormitory #3, midnight.
 
 
TRIXIE (whispering, but rather loudly): Hey… hey! Bookface!
 
TWILIGHT: Bookface?
 
TRIXIE: Ugh– whatever! Will you just turn that accursed light of yours off already? The glare is destroying my eyes!
 
TWILIGHT: Why don’t you try closing them?
 
TRIXIE (furious, still somehow whispering): Do not give me your attitude tonight, Sparkle! I am not in the mood!
 
TWILIGHT: Look, Trixie, I’m sorry. I’ll dim my light. But you have to understand, I have a lot of studying to do, and I have to squeeze it in whenever I can. Headmistress Celestia told me I–
 
TRIXIE (mockingly): ‘Oh, look at me, I have a special assignment from the headmistress! I have to stay up all night and study because I’m too special to study during the day like a normal pony!’
 
TWILIGHT: You know that isn’t what I said, Trixie, I only meant–
 
TRIXIE: What? Did you mean to say you supposed I’d enjoy getting one more reminder of how much Celestia just adores you, how much she trusts you… I mean, she must trust you, considering she assigned you to a Fourth Year book that not even Sunset Shimmer has had access to. (She flops onto her back, sighing bitterly.) And why shouldn’t Celestia value you? You’re a natural. Magic is like your native language. It’s like you don’t even have to try.
 
TWILIGHT (not sure whether to feel hurt, complimented, or just confused): But… I do try. That’s why I’m staying up to study, Trixie… I’m trying to do my best to understand this assignment.
 
TRIXIE: And I suppose you think I don’t try?
 
TWILIGHT: I never said that–
 
TRIXIE: Oh, please; I can smell condescension a mile away. (She burrows underneath her covers, pulling them up over her eyes.) Just dim your light and do your stupid assignment, Sparkle. If I fall asleep in Conjuring Class tomorrow I’m blaming you.
 
(Twilight looks up at the bunk above her for a moment. She isn’t sure whether to be offended by Trixie’s accusations or to feel sorry for her classmate, who struggles in class while she, herself, breezes through most subjects. After she hears Trixie start fake-snoring, Twilight returns to her book, dimming her light… but just a little.)
