_____________

A raspy voice echoed throughout the Bunker, capturing your attention. It was different than the voices of your boys but you were quite acquainted with this rare voice.

You peeked into the library before entering, finding Sam, Dean and Castiel staring at a man in black with blank expressions, as if completely uninterested.

They brightened up when they saw you approach them, shifting their attention from the King of Hell and looking at you.

He looked back and grinned, "Hello darling." You raised an eyebrow, squinting slightly as he continued to watch you with interest, "Didn't realise the Winchesters and feathers here housed you under this roof."

You crossed your arms, this was the second or third time you had seen Crowley and interacted with him. "Well... Get your facts straight," You said with a stiff jaw and he smiled slightly, turning back to Team Free Will.

"So boys, what's the verdict? Will you help?" Crowley asked, biting his lip with being hopeful. Sam and Dean huffed. "We'll discuss and get back to you," Sam said with a forceful smile and Crowley rolled his eyes.

"Oh come on! I put up a valid and worthy case!" He said loudly, "A few of my demons have joined and gone rogue and are causing problems and chaos everywhere, they're definitely the suspects in the case you're working on."

"Crowley honestly, we don't need to and want to work with-"

"Hey maybe he's sharing something useful," You intervened then looked at him, "How powerful are these demons exactly?"

The boys looked at each other with confusion, wondering why the hell you've suddenly taken an interest in what Crowley has to say.

"Yeah exactly, sexy here has got a point," Crowley smiled smugly while you smirked at him. Stepping ahead to knock yourself out of your thoughts, you leaned on the table and said, "Alright Crowley, don't push it."

The Winchesters watched you intently but Castiel... he was about to explode at the sudden hint of chemistry between you and Crowley, not because of envy but because he cares about you and the King can be a bit dodgy sometimes.

"So what I've been saying, I'll repeat it for you love," He said then walked over to the whisky cart, pouring himself a glass.

"Yeah sure, help your-"

"Would you like a glass?" He asked you and you nodded slowly, watching his every move, genuinely curious about knowing whether he really is interested in you or not.

You glanced at Castiel after Crowley handed you a glass and the Angel had his hands tightened into fists, ready to attack in case Crowley does anything.

You winked at him discreetly then turned to the King to hear what he has to say. "So to recap for your... slow minds," Crowley started, "Demons have acquired strong powers from different sources: spells, creatures and harnessing the ability to do all kinds of things that they couldn't. This of course had led to the rise of theft and crime as you all are aware and I believe... no, I'm sure that the case involving the severed banker can be pinned to these demonic sons-"

"Okay Crowley so fine we'll help, what do you want from us?" Dean asked and Crowley smiled. "Research and help me locate these demons so I can end them and give them a lifetime of torture they deserve!" He said loudly with rage.

The Winchesters looked into the file room while you researched on your laptop doing the usual hacking and reading. Crowley sat opposite you with his head on his hand, completely bored.

You grinned, deciding to do something. "What's wrong Crowley?" You asked but imitated his British accent. He widened his eyes, surprised by your sudden tone.

"Uh... Nothing, is solving cases always this quiet?" He questioned and sighed. You chuckled and continued to the accent, "Oh Crowley, you should find something to captivate yourself. Why don't you go for a walk?"

He squinted his eyes, trying to figure out why you put on a British accent. "Me? King of Hell, go for a walk?! That's absurd," He said, staring at a spot on the table.

"Alright but I'm going to be busy for a little longer-"

"Why are you mocking me?"

You paused, biting your lip then smiled, but didn't say a word and continued to focus on your laptop.

*****

A few long and boring days later...

Though, not so much for you.

While Sam, Dean and Castiel continued to complain about how Crowley doesn't deserve their effort and attention, or how all of his 'sources' and information aren't reliable, you were engaged in quite an interesting development.

You had continued you 'let's imitate the King of Hell' shenanigans and Crowley had grown to become moody, agitated and extremely on edge.

You loved to have the thought of satisfaction that you could bring Crowley to his knees... or at least make him feel like asking the Winchesters for help was a bad idea.

"Would you like anything? I'm making a cup of tea and having some biscuits," You told him as you followed him around like a lost puppy. You found all this way more fun than tracking down 3 demoms.

"No I'm fine! Leave me the hell alone!" He shouted, up on stopping abruptly and turning around. After shaking off your surprise you said, "Why what's wrong? I thought you'd feel more at home if I talked like this."

You batted your eyelashes at him and he stared at your facial features, looking at each with great interest.

You were completely wrong about making him annoyed and sick of the Bunker's inhabitants. More than that, he was actually turned on by how you sounded with the accent. He loved how the words rolled off your tongue and realised how good you sound with the accent.

Arousal is more of a feeling than regret and you had no clue about it. He hides it pretty well...

"I'm warning you Anne, if you don't stop I will make sure you never speak a word in that accent again," He said with gritted teeth, "It does... THINGS."

You crossed your arms and smirked, "What things?" Crowley grunted walked ahead, trying his best to ignore your presence otherwise he'll end up needing you to make himself feel better.

"What 'things' Crowley?" You called out, "Could I be a good Britisher?!"
