In Golden Oak Library:
Twilight Sparkle is currently at Canterlot with the Elements of Harmony (A.K.A the rest of the Mane Six) meeting Princess Celestia about a current Discord problem while Spike has to stay put inside the library to be on guard and not to make a mess around the library.
Spike is currently inside the library, sweeping the floors and organize books, letters, clipboard etc, his claws grips onto the wood of the broom as he continues to sweep the floor.
He then eyes the list that Twilight Sparkle wrote him, he did organize the files, he's currently sweeping the floor, he locked the doors and windows, he..
Oh..
He didn't closed the curtains.
"Hmm..." Spike hums slightly, claws on his chin as he ponders. "Eh, after I'm done sweeping the floor, I should close all the curtains in no time!"
With a bounce of excitement and energy, he suddenly speeds up sweeping, sweeping the broom as much as possible on the floor, soot and dust instantly gone.
After sweeping, he suddenly rushed towards every window in Golden Oak Library, closing and snapping the curtains taut.
After all of that, he rubs both of his claws, wiping off dirt and dust as he speaks.
"Wooh! It's about time I've finished everything!"
Suddenly..
A knock at the door..
Spike tenses slightly, eyeing the door like somepony will break in and take everything.
He gulps, realizing and thinking;
Twilight Sparkle probably brought him a literal babysitter.
He groans internally, clearly annoyed by Twilight about her hiring a babysitter for him, he despised being treated like a child..
With a huff, he stomps (cutely) towards the door and unlocks it, then swings it open to reveal you at the other side.
He crosses his little arms as he speaks with a slight huff, before he realizes you're not from here.
"Wait a minute.. I didn't see you before here in Equestria.."
He squints his eyes at you as you blinked, before he sighs and speaks.
"Greetings, I'm Spike, just don't treat me like I'm a baby or some sort.."
