Sequins

Twilight Sparkle sat in her castle library, dusting off the bookshelves as she reorganized them. She enjoyed maintaining her library, and had only hired one other pony to aid her, as she could easily do most of the work on her own. Her assistant was currently sorting the books on agriculture nearby, and Twilight couldn't help but notice how well her fiery red mane complimented her lemon yellow coat as it was swept back in a big pink ribbon, tied into a bow. The door opened, and she looked over to see her niece, Party Pop, walking into the library. She noticed almost immediately how miserable the snowy white mare looked, her lilac mane drooping slightly, as her mothers' often did. She immediately stopped her work and walked up to her, leaving her assistant in a mad scramble to catch the suddenly falling books. She put a caring hoof on her shoulder, ready to soothe her only niece.

"Party Pop, what happened? You seem upset about something."

Party Pop blushed and looked away. "It's dumb..."

"Aw, c'mon, you can tell me anything! Nothing's too silly to tell your auntie Twilight!" She chirped, momentarily oblivious to how serious the issue might be. Marrying a chaotic being had helped her stop being so uptight, but sometimes she relaxed a little too much.

Pop's lip trembled for a moment, then she flung herself onto her startled aunt, sobbing as if the world would end. "I made a new garment design, and showed it to mom, and she stole it, claiming it was her design, and showed it off during fashion week in Canterlot! She completely betrayed my trust! Nopony will ever take my work seriously again! MY CAREER IS RUINED!!!" She bawled, occasionally pausing to hyperventilate. Twilight stood frozen in place, horrified at what had happened. She knew that her sister could be a very competitive designer, but she never thought she could be selfish enough to do something like this.

"Oh, Pop, that's horrible..." She said, stroking the mare's mane gently as she sobbed. Twilight had never seen her niece so upset about anything in her life. Then again, she had never seen her sister be such a bucking bitch to anypony either. Rage began to well up inside her as she processed the best possible course of action for her to take. "Do you want me to talk to her?" She asked, trying not so sound as mad as she was. Pop sniffled gently as she looked up at Twilight.

"Ok."
