"Hey, Twilight," Rainbow said coolly as she trotted into the Golden Oaks Library*
*This is pre-Twilight's Kingdom, yo!
, "what's up?"
Twilight looked up from helping a pony check out books, which despite being something I've never actually seen happen in the show, (which is really dumb if you think about it), I have to imagine would be part of her duties as a librarian, and mouthed "One moment," to Rainbow. Rainbow patiently waited. Okay, who am I kidding, she trotted in circles and flicked her fuzztacular ears adorably and generally made a show of being impatient. I mean, her being impatient is literally the main plot point in the last chapter; I can't completely abandon characterization now, can I?
Nevermind, don't answer that question.
Twilight finished helping said pony, and thusly turned her attention to Rainbow Dash. "Why, hello, Rainbow. You're up awfully early. What brings you here? It can't be to check out a new Daring Do book, as the next one doesn't come out for another four months. Maybe Dave Polsky should write an episode about that! Maybe Super Trampoline should write a joke about that episode in a different story that won't come out for another however long it takes him to finish it! So anyway, are you here to learn?" She said this with a glimmer of hope in her eyes, the hope that Rainbow Dash might actually read something beyond Daring Do, like, say, Earth Pony Family Structure in the Posey Era or something else equally boring, dry, and pedantic to everypony but Twilight Sparkle.
"Actually, Applejack's Haberdashery doesn't open for another half hour, so I figured I would bug you."
"Oh, jeez, lucky me," Twilight said, only half sarcastically, because while Rainbow could be annoying, she did nonetheless truly enjoy spending time with her. But then she gasped and stars briefly appeared in her eyes like this was Steven Universe or something, and she spoke thusly:
"Actually, Rainbow, there is something you can help me with."...
