Sweetie Belle waited.
She didn't like waiting, because when you were waiting you weren't doing anything and she liked doing things. But she had to, otherwise she wouldn't be here when Twilight left and she wouldn't be able to sneak in. Technically she didn't have to sneak in, but where was the fun in that? Anyhow, if her clock was right then Twilight would leave any second no-
The libraries wooden door slammed open, shaking a couple leaves from above. Sweetie jerked backwards at the sudden motion, and dived for cover. A lavender unicorn strolled through the entrance, her scaly purple-and-green assistant following behind her.
Twilight Sparkle shielded her eyes from the sunlight for a moment, before scanning the area for anything she should attend to. Naturally her eyes settled on the white filly hiding behind a flower.
"Sweetie Belle," asked Twilight. "What are you doing here?"
Sweetie panicked, she had been spotted! She had to come up with an answer now or she would be caught.
"I-I, uh, I'm gardening!" she proclaimed.
"Uh-huh, and that's why you're wearing a spy outfit?"
Sweetie Belle looked down at herself. Sure enough, she was decked out in a black costume that any espionage-ier would be proud of. She'd found it in Pinkie Pie's trash. It was fairly baggy and stunk like mouldy tree sap.
"Of course!"
Twilight stared at the young filly, her expression rivaling even the deadest pans.
Finally, after an eternity, she sighed in defeat.
"Well, okay then. You enjoy your gardening."
"Okay, Bye!" replied Sweetie Belle.
Twilight nodded towards the little "Gardener", turned away and trotted off, Spike following close behind.-
Sweetie Belle turned to the closed, locked door of the library.
"Oh."
Later
Twilight was walking back from the shop. She'd almost bought a sofa before realising she didn't have anywhere to put it.
Still, it would have been a nice present for Rarity.
She quickly unlocked the door with her magic and jumped back when a white filly shape dashed inside.
"Aha!" It shouted triumphantly. "I'm in!"
"Sweetie Belle." questioned Twilight. "What are you doing?"
"Oh!" Sweetie turned to face the Librarian/Princess/Royal Student.
"Um... Gardening?"
Twilight looked unconvinced.
Sweetie made a mad dash for stairs leading down. Twilight exclaimed, before following her.
"Hey, Sweetie Belle, wait!"
As soon as she was out of the stairway the unicorn filly galloped to the toolbox on the workbench and grabbed it in her teeth.
She turned to go back up the stairs, only to come face-to-face with a certain lavender mare.
"Sweetie Belle," Twilight asked dangerously before shouting. "WHAT ARE YOU DOING HERE!"
"Uhm, mekamic." Sweetie's answer was muffled by the box in her mouth.
"You know you could have asked!"
Sweetie Belle place the toolbox down, and stared up at Twilight.
"I could have?"
Twilight introduced her hoof to her face.
Even Later
Sweetie Belle was trotting along the path, toolbox in her magic. Twilight was right, this was a better idea!
She was on her way to Sweet Apple Acres, where the CMC clubhouse was, inside of which was the object she was going to use to get her mechanic cutie mark! She wasn't exactly sure what it was but it had gears, which only mechanical things had.
She knocked on the clubhouse door.
"Password?" a voice spoke from behind the doorway.
"We don't have one yet, remember." Sweetie replied.
"Oh, right."
The door swung open, revealing Scootaloo behind it.
Behind her was a large, complicated looking, machine. The book next to it called it an "engine".
Sweetie Belle knew what an engine was. They were on trains. But this one, despite its size, was much smaller than those ones.
"Do you have the tools?" asked Scootaloo.
"Mm-hm."
The white filly floated a wrench and a screwdriver out of the toolbox.
"Lets get started."
Dawn of the final da- I mean... EVEN Later
"Hmm, hm hm hm. Hmm, hm hm hm."
Sweetie Belle hummed to herself, knowing that the finish was drawing near.
"Wow Sweetie Belle, thats really good!" exclaimed Scootaloo.
"Thanks! I dont know what we'll use it for, but it must be usefull for something. Right?"
"No, I meant your-"
"Quiet! Im going to test it."
She wiped the sweat from her brow. It had taken forever, but she had done it.
She flicked the switch, and stood back as the engine roared to life.
The filly was giddy with excitement. After all she had gone through, after all the difficulty, she had done it.
Surely this would get her her cutie mark!
"As I was saying," continued Scootaloo. "Your singing was really good!"
"Oh, thanks, but were trying to get are mechanic cutimarks right now, remember."
"I guess you're righ-"
Scootaloo gasped. "Sweetie Belle, look!"
Sweetie turned to look at her flank and gasped as she saw a bright light cover it. She had it! She had a cutie mark of mechanical-
The light faded to reveal a note symbol with a light pink outline.
"Huh?"
From the other side of the engine, Applebloom poked her head up.
"Hey girls! What do yall' think of the engine I just fixed!"
She grinned.
"I even got my cutie mark!"
Sweetie belle stood with her mouth hanging open, while Scootaloo facehooved.
"Wha- How- But-" Sweetie sighed.
"It doesn't matter, I still have my cutie mark now anyway, even if it wasn't the one I was trying to get!"
She grinned. "And besides, this means I can become famous!"
