January1815 – Yeah if Fili and Kili are involved happy endings are a guarantee!

Rachetg – You might have to wait a bit for that to happen.

Bleeding Blue Kunoichi – I never really thought about it until I wrote the chapter. And you're right; that will be too easy.

Nice Egan – Yeah that won't be the last time either. I always feel Fili never got enough love in the films so I always try and give him some in my fics.

Reader-anonymous-writer – It's only going to get worse.

Treachery of All Kinds

Fira drew her knees to her chest in a vain effort to stop her shivering. She had woken up to find herself locked in this cell. On one side of the wall there was a flight of steps leading up to the barred door. As her bound hands dug into her back Fira bit her lip. Even without her bonds she wouldn't have moved. Thorin was right to lock her up like this. She was dangerous. Supposing she accidently hurt one of the company?

Leaning against the stone wall Fira licked her dry lips nervously. What would the others be doing now? She remembered watching Thorin punch Kili before being punched in turn by Fili. Tears leaked from her eyes. She should have tried to stop Thorin. Instead she had just sat back whilst the man she loved had gotten hurt. She wasn't fit to be his One. She would only end up hurting him again as she had done so many times.

"Thorin put her down here?"

At the voice Fira curled into a small ball. Kili couldn't be down here. If he was here then he would be trying to get her out. She couldn't let that happen. She had to stay here until she was safe.

"These are the deepest dungeons lad. They go miles beneath the mountain. Thor use to bring prisoners down here to scare them. After all; no one would hear them scream."

Gulping Fira held her breath as Balin carried on talking. She wasn't bothered about what he had to say. Instead she just listened out for the footsteps that drew closer and closer towards her cell.

"Fira?"

At first Kili's voice was faint. But as he moved closer and closer Fira could make out the despair. The terror. Knowing she would later regret this she cleared her throat.

"Kili I'm here!"

"Fira!"

In the dark light Fira watched as Kili grabbed the bars that locked her in. He sank to his knees; gripping the bars as if he was about to tear them apart.

"Oh Mahal! Did he hurt you? Are you alright? Please just tell me you're alright?"

Nodding Fira could see Balin standing behind Kili. The older dwarf smiled.

"I'll wait for ye lad."

Kili didn't acknowledge this as the dwarf moved away. Forcing herself to her feet Fira stumbled towards the steps. She hadn't stood up since waking up and unsurprisingly her legs wobbled. Tripping several times she finally reached the steps and hurried up them to join Kili. Sitting down on the other sides of the bars she smiled. He reached his hands through and caressed her face.

"Forgive me darling," tears dripped down his cheeks, "Please forgive me. I should have stopped him. I should have fought him; anything to help you."

Fira began shaking her head when she realised Kili was staring at her.

"What is it?"

"He…he tied you up?" Kili's white face was expressionless, "Turn around."

Compiling Fira couldn't help her smile as she felt Kili take hold of her wrists. Even now his touch was gentle. As though he was afraid the slightest bit of pressure would hurt her. Kili pulled the last of the ropes away and Fira turned back to face him. Without saying anything she reached up to grab the bars with one hand whilst gently stroking his face with the other. Kili took her hand and pressed it to his cheek.

"I'll get you out," Kili kissed her hand again before letting it go, "Just…I don't know how yet but I'll get you out."

"Kili…"

He shook his head, "He'll pay for this Fira. I swear to you I will punish him for treating you like this."

He moved as if to get up and Fira grabbed his hands to stop him.

"Kili wait."

Blinking at her he sat back down. Gripping his hands tightly Fira shook her head.

"Don't."

"Don't?"

"Just leave me here Kili."

He recoiled, "Are you insane? Fira in case you weren't aware Thorin has locked you up!"

"I know, I know. But even if he's mad he was right to do so. I'm dangerous Kili."

"No," he shook his head but Fira could see it in his eyes, "No Fira. Look if I can get you out then maybe…"

"Maybe what? Kili I have no idea if my Dragon blood will try and control me again."

"But you can fight it. Can't you?"

Pressing her forehead against the bars Fira could feel her own tears coming.

"No Kili I can't. I'm not strong enough to fight it. If it takes me again there's no way of knowing what I'll do. I could hurt any one of you. If I was to hurt you…just the thought of it makes me want to scream!"

Fira said nothing as Kili gently lifted her head up to face him. His cheeks were wet with tears.

"I believe in you Fira. I know you'll be able to fight…whatever this is. I'll help you. We'll fight it together," he grabbed her hand, "I meant what I said. If it tries to take you I won't let you go. I'll never let you go."

"Kili…" Fira shut her mouth. Why had he come down here? He should have stayed away from her? Then this wouldn't be so hard. Shaking her head she looked at him square in the eye.

"Kili please…just for once stop being stubborn and just listen to me. I'm not safe. I'm a danger to all of you and I don't want to risk hurting you more than I already have. Please just…just go."

"Fira..?"

"Just go!"

Pulling her hand away Fira turned and hurried back down the steps. Only when she was safely in the corner of her cell did she dare look up. Kili got to his feet and held the bars grimly.

"I don't care what you say, I know you can fight this. I'm not going to stop believing in you. I'll get you out of here Fira. I promise."

Not saying anything Fira simply sat and watched as Kili moved away. His footsteps began to die down and only when silence fell did she allow herself to cry.

Keeping his head bowed Kili had to keep blinking back his tears. He shouldn't have left Fira. He should have gone back to try and get her out. Seeing her locked up like that had torn him apart. To then go and leave her was even worse. But he knew, deep down, it was for the best. Fira was right; she had no idea if she could control herself around the gold. For now at least it was better she stayed where she was.

That didn't mean he had to like it though.

"Kili?"

At his brothers voice Kili forced a smile onto his face. Fili rubbed his shoulder.

"How is she?"

"She's fine," Kili nodded, "I mean she's been better. She told me to leave her there until she knew she was safe."

"Fili licked his lips, "But…we don't know if..?"

Kili nodded, "I know."

Fili pulled him close, "I know this isn't the best time but you need to come to the armoury."

"Lad what's happened?"

Kili had completely forgotten Balin was there! Fili nodded grimly.

"It's not just the people of Laketown who are angry with us."

"I don't understand," Kili blinked, "Who else..?"

Fili sighed, "Thranduil."

When they reached the armoury Kili caught a glimpse of Thorin standing against the wall beside Bilbo. Setting his jaw he forced himself to walk to the far corner with Fili at his side. As he passed the others they shot him small smiles; but he ignored them all. Yes he had failed Fira. But so had the others. They should have stopped Thorin. They should have saved her.

"Kili?"

Nodding absentmindedly Kili shed his thick coat and replaced it with one made of chain mail. He watched Fili grab a similar garment before turning to the wall of weapons. Taking several knives down his eyes scanned over a bow propped up in one corner. Not bothering to ask how it had gotten there he grabbed it and the quiver of arrows. It felt good to hold one again. Sheathing his sword he turned to see Fili take a huge war axe down and give it an experimental swing. Kili licked his lips.

"Fili what exactly is going on?"

His brother glanced at Thorin before nodding.

"I don't really know. He just told us to prepare for a fight."

Nodding Kili's hand hovered over his sword hilt and Fili shook his head.

"Kili I know you're angry with him…"

"I hate him."

Fili didn't respond to this remark, "I know you're angry but right now Thorin doesn't matter. By the sounds of it we have an army on our doorstep."

"I know," Kili smiled, "But when this is over I'll see he pays for what he's done."

Fili nodded and Kili turned to see Mithiel behind them. Unlike the others she had no armour except the clothes she wore. However she'd made up for it by arming herself with as many weapons as possible. Fili took her hand.

"If I asked you to stay behind..?"

"I would say no," Mithiel kissed him, "I'm fighting by your side and that's that."

Kili smiled to himself. He knew if Fira were here he'd want her to stay. He also knew she'd fight him tooth and nail before he gave in. Shaking his head he watched as Fili and Mithiel moved away. Trying not to dwell on Fira Kili followed his brother and the others.

As they reached the top of the huge flight of stone steps Kili tried not to show how tired he was. The wind whipped through his hair as he took his place beside Fili. Glancing down his stomach gave a small plunge. Forcing himself to ignore the dizzying drop he instead stared out in horror at the huge elven army that stood before them. At the very front stood a huge moose and Kili could see Thranduil sitting atop of it. He clenched his fist; he could still picture the bruise of Fira's cheek. A bruise Thranduil had given her. As two horses came to a halt beside Thranduil, Kili couldn't help but smile at Bard. This man wanted nothing more than what was owed to him. He deserved the gold far more than any of the company did. But what Kili hadn't been expecting to see was the horse next to Bard's.

"Gandalf?"

Fili shared his confused look and Kili risked a glance over at his uncle who merely raised an eyebrow. Gandalf's horse inched forward and the wizard glanced up.

"Thorin!" His voice boomed up to the company. "This is madness!"

Thorin gave Gandalf a sneer. "At last you have decided to join us. Much has happened since you abandoned us Gandalf!"

"For goodness sake!" Kili had never seen such anger in Gandalf's eyes. As he saw the cuts on his face he wondered what had happened to him while he had been gone. He couldn't help but hope it had been worth it. If Gandalf had still been with them then none of this would be happening.

"What are you doing Thorin? This is no way a king behaves!"

Thorin's whole body stiffened and Kili cursed Gandalf's words. However the dwarf king relaxed and smiled.

"I shall show you how a king behaves wizard."

"Listen to me!" Now Bard was having another go.

"There is a way we can end this peacefully. A way that will satisfy us all."

Thorin frowned at this whilst Kili looked at the stunned faces of the dwarves. Only Bilbo seemed shocked and when Bard put his hand inside his coat pocket did Kili get why the hobbit looked so nervous.

Bard gave a smug grin whilst the dwarves looked on in horror at the Arkenstone in his hand.

None of the dwarves dared look at Thorin. The expressions on his face ranged from anger, sadness and pure denial. Kili sneaked a glance at Bilbo who was wringing his hands desperately. So he had had it all along. Kili smiled at Bilbo. How the Hobbit had been able to sneak it out he would never know. But by the looks of things this hadn't been part of Bilbo's plan. Leaning forward Thorin growled at the smug smiles of Bard and Thranduil whilst Kili watched several of the older dwarves seething.

"How in Durin's name did they get their hands on it?" Dwalin gripped his sword hilt harshly whilst Fili shook his head and shot Bilbo an odd look. Bard slipped the Arkenstone back in his pocket.

"I propose a trade. I will give you back your Arkenstone if you agree to honour your agreement and give us our share of the gold."

Thorin was already shaking his head and Kili knew Gandalf was once again at snapping point.

"For once in your life Thorin Oakenshield will you put your pride away!" The wizard bellowed.

"This is your once chance to put right your wrongs! Don't make the others suffer because of your incompetence!"

Thorin laughed before smirking at Gandalf.

"You think you can fool me? You believe me to be stupid enough to fall for such a ruse?"

"Thorin?" Bard blinked up at the mountain king who shrugged his shoulders.

"The Arkenstone still lies within Erebor. What you are offering is a fake."

"No it isn't." Bard yelled.

As Thorin glanced at them all Kili inched closer to Fili. Thorin's eyes darted across the company.

"Who was it? Who betrayed me like this? Who betrayed the line of Durin?"

"Thorin..?"

Fili got no further. With a roar Thorin hurried forward and grabbed him by his collar. He gave him a shake.

"You did this didn't you? All this time you've sought the throne for yourself! You wish to see me destroyed by taking away what is mine!"

Fili pushed him away and Kili drew his sword. Thorin raised an eyebrow.

"Of course. Fili wouldn't do this alone would he? No; he could get his baby brother to help him."

"Shut up," Kili snapped, "We haven't done anything Thorin. I swear it."

Thorin raised an eyebrow.

"Were you that desperate to 'prove' yourself? Is this the only reason you wouldn't stop whining about wanting to join the company?"

Kili tried to ignore his flaming cheeks. Beside him he saw Fili inching closer.

"Leave him alone Thorin."

"Always defending him," Thorin glanced at Fili and Kili couldn't stop his gulp.

"Always sticking up for him. I suppose you have to give he can never defend himself."

Sensing Fili was happy to hit Thorin again Kili stepped in front of his brother. Thorin dug his sword into his neck.

"You will both pay for what you have done to me."

"It was me!"

Kili wasn't the only one to stare at Bilbo. The Hobbit nodded.

"They didn't take it. They had nothing to do with it. It was me. I found it and took it to Bard."

"Why?" The king couldn't bring himself to speak. Bilbo bit his lip.

"It's turning you into a monster. When we first began this quest you would have done anything to protect the lives of this company. But since coming here that Thorin has gone. I've no idea if he's ever going to come back."

"You…you betrayed me!"

Thorin was backed Bilbo towards the edge of the battlements.

"Thorin?" Balin inched nearer before freezing as Thorin shot him an icy glare. Bilbo meanwhile stumbled slightly and Thorin took the chance to pin him down. As the wind whipped through his hair he gave a small squeak.

"THORIN!" Gandalf forced his horse forward.

"I would appreciate it if you didn't damage my burglar. I still have some use for him."

The dwarves waited for what was no doubt the longest few seconds of their lives. When Thorin let go of Bilbo Kili could feel the relief spread throughout the company.

"You are forever banished from these lands!" Thorin snapped. Bilbo bit his lip whilst Thorin rounded on him once more.

"If I find you within these walls I shall throw you from the highest peak of Erebor."

Nodding Bilbo hurried to the very edge of the balcony. Kili watched as he began letting himself down on a thick rope he had tied there. No one said anything as the hobbit scrambled to safety as fast as he could. Ori had tears falling down his face whilst the others had no idea where to look.

"You will pay for this!" Thorin roared. As he began hurrying down the steps Kili glanced at his brother who was gripping Mithiel's' hand tightly. Biting his lip Kili hurried after his uncle. He couldn't be sure but he had a horrible feeling Fira was in danger.

Storming through the castle Thorin found himself shaking all over. He should have known it was Bilbo. The Hobbit had been far too willing, far too eager to help. Why else would he even come on this quest in the first place if not to steal the stone? And that Dragonborn? She had helped him of course. Right from the start they had plotted together. Who else could it have been? Even if his company hadn't proven their worth Thorin knew they wouldn't betray him. But outsiders on the other hand?

His steps quickened as he neared the dungeons. Bilbo was banished and as for the elf, she too would be punished for her role in this. No doubt she had used Fili to try and get her hands on the treasure. As for Fira..? Thorin smiled; banishment would do no good. If she left Kili would leave with her. He needed to free his nephew from the Dragonborn clutches before it was too late. Opening the main door that led to the dungeons Thorin nodded.

She would be punished for what she had done; and she would pay with her life.

So yeah Thorin isn't snapping out of his madness any time soon. But we are getting closer and closer to the main battle which I'm really excited about. Let me know what you think xxx
