Clara Oswald liked to sing.

In her spare time, she would dance around her room with hr music on full blast, singing her heart out into a hairbrush.

Her YouTube channel consisted of very many playlists of different genres, artists, and random songs for different moods.

Today, she thought, seeing as she was on her own, she would take the opportunity to open her window wide and sing at the top of her voice. She was in a happy mood… what song should it be this time?

She grinned: she knew just the one…

Pushing open her window, she checked nobody was outside to hear her, and sniggered as she hopped off the windowsill (That she had had to stand on to reach the window. Oh, the joys of being 5' 2"…).

She cleared her throat, snatched up the hairbrush that was idly lying on her bed sheets, closed her eyes and, with a sad smile on her face, started her song…

"Primadonna girl… yeah, all I ever wanted was the world. I can't help that I need it all, the primadonna life, the rise and fall. You say that I'm kinda' difficult, but it's always someone else's fault, got you wrapped around my finger, babe: you can count on me to misbehave… primadonna girl-"

The sad smile on her face turned to a manic grin as the music picked up pace.

Clara Oswald didn't just like singing… she liked dancing.

"Would you do anything for me? Buy a big diamond ring for me. Would you get down on your knees for me? Pop that pretty question right now, baby! Beauty queen on a silver screen, living life like I'm in a dream! I know I've got a big ego, I really don't know why it's such a big deal, though-"

I say dancing, but what I really mean is looking like she's playing charades with the invisible man. Leaning on the windowsill with one elbow, looking like a singer in her element, wearing the happiest grin on her face, she couldn't be more hyper.

"And it's sad to the core, core, core: every day is a chore, chore, chore! When you give, I want more, more, more. I wanna' be adored! Cause I'm a primadonna girl. Yeah, all I ever wanted was the world… I can't help that I need it all, the primadonna life, the rise and fall…"

Hopping up onto the bed and wobbling a bit, holding the hairbrush in both hands, Clara dropped her voice to a quieter note, listening for anybody passing outside, still wearing that manic smile.

"You say that I'm kinda' difficult, but it's always someone else's fault. Got you wrapped around my finger, babe, you can count on me to misbehave… Primadonna girl!"

At this point, her room was getting too restrictive, so she bounded down the stairs, two at a time, carrying her bluetooth speaker under her arm, not stopping singing,

"Fill the void up with celluloid, take a picture, I'm with the boys! Get what I want cause I ask for it, not because I'm really that deserving of it… Living life like I'm in a play! In the limelight I want to stay! I know I've got a big ego, I really don't know why it's such a big deal, though…"

Bounding into the kitchen, she clicked on the kettle and turned up the music to drown out the noise.

Unfortunately, she also drowned out the noise of a knock at the door…

"Going up, going down, down, down! Anything for the crown, crown, crown! When the lights are dimming down, down, down, I spin arou-ou-ound, cause I'm a…"

Also unfortunately, when she did spin 'arou-ou-ound', it left her in the hallway. Looking down the hallway, Clara could see, through the window, a disapproving face staring back at her.

Clara swallowed and turned her music off.

She waved, awkwardly, miming 'Hi' down the hall.

Missy was not amused.
