A/N: 
I should probably warn you that I had fun writing Mean Killian. XD If you like soft and sweet Killian, this fic is not for you. I like the villains ;) Friendly reminder: This fic is AU. 

When Kassidy opened her eyes the first thing she noticed was her head was throbbing. The second thing she noticed were hands were bound. She blinked her eyes a couple of times before taking in her surroundings. What she could see of them anyways the room was dark, and cold so she could only see a few feet in front of her. She looked down at her rope bound hands and pulled trying to free herself but it was no use. She screamed in frustration and then looked down at the blood stains on her dress.

"R..Run." Elliot sputtered out.
"No.. I can heal you." Kassidy said placing a glowing palm over his wound.
"No.. they can't know... about your...magic. Run." Kassidy shook her head.
"I won't leave you." She said and pressed her lips to his cold forehead.
"You have to. He's coming." Elliot said. Kassidy looked over her shoulder at the enraged pirate captain marching towards her.
"He can take me. I won't leave you. Not until the last breath leaves your lips." She promised.

"Elliot.. I'm so sorry." Kassidy cried to herself. He should have let her heal him. She should have heeded his warnings and gone home. She should have never even left the palace and now, Elliot was dead because of her, and she was trapped in a cold dark room. She heard footsteps above her and then suddenly they were getting closer and closer to her. She squinted at the sudden light that was coming from above. She moved herself putting as much distance between herself and whoever as coming down the stairs as possible.
"No worries. I won't hurt you princess." A soft voice said. She looked up at the man who was approaching her with a bowl of food. He was a round bearded man with a red knit hat. He set the bowl in front of her.
"I'm Smee, I brought you some breakfast Princess." He smiled. Kassidy looked down at the bowl of questionable food and back up at Smee.
"I demand to see the Captain." She spat.
"He will be by soon enough." Smee said in a promising tone. "You should eat."
Kassidy lifted her bound hands.
"Am I to eat like a dog?" She asked.
"Oh, my apologies princess. I'll untie you, but I ask that you don't try to run. Please." Smee said.
Kassidy gave him a nod.
"Okay." She said. Smee cut her hands free. Kassidy flexed her wrists and looked up at him.
"Thank you.. Smee was it?" She asked.
"Yes Princess." Smee smiled.
"You aren't a very smart man are you Mr. Smee?" She asked before barreling into him knocking him out of the way and darting up the stairs.
"Oh Come on! I said please." Smee sighed the Captain was never going to let him live this down. He ran up the stairs after Kassidy.

Kassidy made it to the main deck and looked around and gasped. They were out in the middle of the open sea. Her kingdom far far from view. It wasn't long before she was surrounded by pirates. Her eyes scanned over the men looking for the Captain but he was nowhere to be seen however her eyes locked onto a familiar face. This was the man who had run Elliot through. She quickly pulled the nearest man's sword from its sheath and charged at the man who greeted her with a laugh.
"Best put that away princess before you hurt yourself." He said. Kassidy growled and swept his legs out from under him and stood over him with the tip of the sword to his throat. She glared down at him.
"You killed him." She said darkly her grey eyes darkened with rage.
"Aye. I did." He chuckled. "You should have heard the sound he made when I stuck him."
"Oh. I imagine It sounded much like this.." Kassidy spat and raised the sword ready to plunge it through the man's throat when she felt cold metal against hers.
"Drop it." Hook said firmly.
"Oh. I'll drop it right into his throat." Kassidy hissed. The blade of Hook's sword was pressed harder to her throat and Kassidy could feel little beads of blood dripping down her neck.
"I won't say it again lass."
Kassidy dropped the sword onto the deck. Hook removed his sword and put it back in its sheath.
"Thats a good girl." He smirked. Kassidy turned around and slapped him hard across the face. He wiped the little bit of blood from his lip with his thumb and chuckled.
"I like my women with a little bit of fight in them."
"You son of a bitch.." She said darkly.
"Oh." He said and tsked and wagged his finger at her. "Such naughty words for a princess."
"You'll find Pirate that I am no ordinary princess." She said clenching her fists at her sides.
"You will address me as Captain." Hook said firmly.
"I will do no such thing. You are no Captain of mine." Kassidy spat at him.
"Alright then. Come with me." He said, though didn't give her a choice in the matter he grabbed her arm and dragged her along with him back down the stairs to the room she was previously in. She struggled against him as he forced her to sit and pinned her wrist above her head tying it tightly with a rope that was secured to the wall.
"Until you learn some manners. This is where you will be."
Kassidy glared and spat in his face. Killian wiped the spit from his cheek and put his hand on her throat and squeezed.
"We are a long. Long way from your kingdom Princess, you have no rule here. I make the demands you follow them and the sooner you learn that, the better off you will be." He snapped and then released her throat.
"Why did you take me?" She choked out.
"Because your father owed me a debt that he refused to pay. So I took you instead. Welcome aboard the Jolly Roger Princess, I do hope you enjoy your stay." He said and grinned wickedly before heading back up the stairs and slamming the hatch shut leaving Kassidy in the dark.

It had been hours sitting in the cold dark room with nothing but her thoughts. What the hell had her father done to owe Captain Hook? Why did he refuse to pay? She put her hand over her stomach and groaned, she should have been hungry by now but the unfamiliar motion of being on the sea was making her sicker than a dog and she also really had to pee.
"Hello??" She yelled. Yet no one came. She had no idea what time it was, if it was light or dark, there wasn't as many footsteps as there had been just hours ago maybe everyone was sleeping. If they were they were about to wake up. Kassidy sat up on her knees as that was the only movement she could really do while tied to the wall. She started beating the wall with the side of her fist and screaming as loud as she possibly could before she heard heavy footsteps the hatch was swung open.
"If you don't shut the hell up down here You will be gagged. " Hook growled.
"I have to pee!" Kassidy groaned "And i'm going to be sick."
Hook walked down the steps with a bucket and set it down beside her.
"This should work for both." He smirked.
"You have got to be joking." Kassidy said looking back and forth between the bucket and Hook.
"Afraid not. Behave yourself and keep quiet or I'll take the bucket." Hook said and back up the stairs he went.
"Oh..I hate you.." Kassidy muttered.

It had to have been morning Kassidy only figured this because the heavy footsteps above had picked back up. She hadn't slept a wink. The hatch was opened and Mr. Smee made his way down the steps with another bowl of questionable substance he would likely present as breakfast.
"You must be starving. I tried to bring you dinner last night but Captain wouldn't allow it. He said you could wait til morning." He said apologetically.
"I'm actually fine. Thank you." Kassidy said
"You should eat. Captain insists."
"Then the Captain, can tell me himself."
"Oh.. I don't think you want that Princess. He's not as nice as I am, you may be stubborn but you won't win."
"I'm not afraid of him. You take that back to him and tell him I kindly refuse." Kassidy smiled sweetly.
"You are playing a dangerous game princess." Smee warned but walked up the stairs anyways. Kassidy waited patiently for the captain. Hook walked down the stairs with the bowl in his hands. He sat on a crate in front of her.
"Mr. Smee tells me you are refusing to eat." He said.
"Right you are." Kassidy said. Hook shrugged and started eating the food in the bowl in front of her.
"Is this supposed to make me change my mind?" Kassidy asked.
"No. I honestly don't care if you change your mind. You don't want to eat? We'll see how you feel after a few days with no food or drink. You are playing a game that I guarantee you won't win. If you starve down here, it is of no loss to me. I have no intentions of returning you home for ransom Princess, you belong to me now. What you choose to do with that, is up to you."
"I get it. My father owed you some huge debt. But what did Elliot do to deserve to die?"
"Still on about the boy? He was just cannon fodder. He shouldn't have gotten in the way." Hook said simply
Kassidy growled and lunged for him but only made it inches in front of his face before the rope restraining her ceased her movement. Hook could have sworn he saw a literal fire in her eyes as for a brief second they seemed to glow orange before she settled back down against the wall with her fists clenched
"Well, I've got a ship to Captain. I will see you in a few days." He said and stood. "I'll have Mr. Smee bring you a clean bucket later." He grinned before walking up the stairs. Kassidy tried to focus her breathing trying to push back the burning rage. She opened her clenched fists that were smoking and glared towards the stairs. Elliot refused to let her use her magic to save his life because if the pirates knew she had magic there is no telling what they would do. She had to do her best to keep it under control but this unruly Pirate Captain was making it harder and harder by the minute.
