Prank Gone Wrong

Summary: After a day with your best friends Bill and Dora, you're accidentally turned into a baby.

Warnings: fluff, humor

Whenever you are with your best friends from Hogwarts Bill Weasley and Nymphadora Tonks, you always get into trouble, this happens since your school days. You may already be adults but some things never change. Today is no different. You're spending the day away with them while your fiancé Narcissa welcomes at her house her sister Andromeda and her grandnephew Teddy for tea.

Narcissa, Andromeda and Teddy are in your fiancé's drawing room sitting on the sofas. She smiles at them though deep down she's sad at being away from you. She tries to pay attention to Andromeda as they chat. However, she's constantly looking either at her watch or at the fireplace awaiting your arrival.

Soon it can be heard the sound of the fireplace and the green flames of the Floo network can be seen in the drawing room, making Narcissa and Andromeda stop their conversation to turn to the fireplace.

However you're nowhere to be seen, only Dora, Bill and... a baby?

Narcissa's brow furrows in confusion as she and Andromeda look at each other before Narcissa stands up from the sofa and walks to the two.

"Ah... what are you two doing here...? And with a baby? And where's Y/N?"

Narcissa's heart pounds in her chest now as she worries over your safety.

"Why did you bring a baby and not Y/N?! What happened to my fiancé?" she says, her voice strained slightly as she looks at the duo for answers.

Andromeda lets out a gasp and covers her mouth with astonishment once she realizes where you are.

"What's going on, Andy?" your fiancé asks confused.

Her sister only nods in the direction of the baby. "Look carefully, Cissa," she says softly in a comforting tone, as if to calm Narcissa down. However, Andromeda's eyes clearly show her concern and slight shock.

Narcissa still furrows her brow in confusion, looking at the baby but not quite understanding why it seems familiar. However, she soon pales and her eyes widen in shock as it hits her that the baby is...

"Y/N...?" she now stares at the baby in shock, her mouth opening but no words coming out.

The baby, well... you, is crying since their arrival, making Dora rock you in an attempt to call you down.

"What happened? How did...?" Narcissa says, her voice not fully in control, the shock still evident.

While one of your best friends continues to rock you to try to calm you down, Bill speaks up.

"Well... Uh..." he stutters, clearly nervous with your fiancé. "You see, Miss Black... My twin brothers Fred and George were experimenting with some new products for their joke store and..." he nods to you. "As you see... It went wrong..."

Your fiancé sighs when she hears your other best friend's explanation and turns to stare at you in baby form, still not having calmed down.

"Of course it had to be those two..." she murmurs to herself. She stares at you silently before she turns to Bill and Dora. "Have you managed to figure out any way to reverse this prank? Did they at least give you a hint?"

Nymphadora shakes her head, a somewhat ashamed look on her face and she tries (unsuccessfully) to comfort you while Bill says:

"They said Y/N will be back to normal in a few hours..." he says with a little uncertainty.

A frustrated sigh escapes Narcissa as she runs her hands through her hair before taking a few moments to steady her breathing and regain her composure.

"So I have to wait hours for my fiancé to be back to normal?!" she says, a little exasperated.
