Kara was helping Merlin clean Arthur's room as they discussed what they were meant to do about the troll. The conversation ceases the minute Arthur enters.

'You need to get out of here. The King's ordered me to arrest you.' Arthur says to Merlin immediately.

'What?' The servants gasped.

'Catrina's accused you of taking her seal.' He explains.

'But I didn't.' Merlin protests.

'I don't want to know, and you haven't got time to explain. If you value your life, you'll leave Camelot right now.'

'Arthur, she is a troll, and she's trying to set me up.' Merlin protested,

'We've been through this.'

He's telling the truth. I saw her too' Kara added but guards knocked on the door.

'I don't care. You need to leave, Merlin.' The knocks continued 'Sire!'

'Go. Go!' Arthur yells and merlin's disappears through the back door.

Kara stood to the side in the court room, Arthur in front of his father and Catrina 'I fear he may have slipped through our net.' Arthur lied.

'You're very quick to give up the chase.' Catrina points out.

'That is because I know my quarry is long gone.'

'How can you be so certain?' Uther asks.

'Well, despite appearances, Merlin isn't stupid. He must've got wind that we were looking for him and left.' Arthur says scratching his eye.

'Outwitting your army in the process.'

'It appears so.' Arthur replies to catrina's comment,

'I thought your men aspired to the same high standards that my father instilled in you.' She said to uther and Kara glared at the woman.

'When I led the army, they did.' Uther said.

'We don't even know if he's still in Camelot. He could be anywhere.' Arthur protested.

'And that's a good enough reason to give up?'

'No, I'm not. It's just that I believe our resources would be better...' Uther interrupted him.

'I've had enough of your excuses. We both have.' He says clasping catrina's hand on his own 'I want the boy found.'

'Sire. My Lady.' Arthur says bowing. Catrina catches kara's eyes and glares. Kara does the same before she walks out after Arthur.

'Way at are we meant to do about merlin's?, she questions the prince,

'There's nothing we can do' Arthur explains and she glares 'if you listened to Merlin and me sooner we wouldn't be in this mess'

'Not with this troll nonsense again' Arthur sighed.

'It's true Arthur!' 'Look, I don't like her very much either but we can't just go around making these accusations'

'But-' 'not another word' he says and Kara glares as he walks away 'prat' she mutters before walking downstairs to gaius's chambers. She found Merlin there with gaius and they immediately hatched a plan to get the guards of their trail.

Kara pulled up her hood and galloped away on a horse later that night. She travelled fro a while before she found a spot that would good enough. She began a fire and took off the scarf she had wrapped around her wrist, it was one of Merlin's. She sat there waiting for when the dawn began to break over the trees, she put out the fire and left the scarf on a log before galloping away.

She retuned just as light broke over Camelot, and after telling gaius it was done she retired to her chambers, falling asleep against the mattress. When she woke, the guards had found the fake trail believing Merlin to be heading north. Though only so much good could come. A new tax had been introduced to the people of Camelot. Kara was outraged, the people barely survived as it was and now there was almost no hope for them.

She had been angry all day so much, gaius had to give her a tonic so her emotions would affect her magic. She rested in the physicians chambers Merlin entering eventually carrying a small bottle.

'I saw her drink some of this potion and a patch of troll skin on her arm disappeared.' Merlin explained as gaius looked the potion over.

'It must be pretty powerful magic to physically change her like that.' Gaius pointed out.

'Could you make a potion that looks and tastes the same as this?' Merlin asks and Kara caught onto his plan.

'I don't know. Yes, I suppose so, but without the troll magic, it wouldn't have the same effect.'

'Exactly. If I can replace this potion with one that isn't magical.'

'Catrina will keep taking it, but it'll no longer work.' Kara finishes and Merlin nods 'And she'll turn into a troll. Think you can do it?'

'I don't know.' Gaius said.

'We have to make the switch before morning or Jonas will notice.'

'Then it's going to be a long night.' 'I was afraid you were going to say that' Kara mutters.

So what's in it?' Merlin questions coming downstairs,

'Nothing too potent. Rat's guts.'

'Nice.' Kara says sarcastically.

'Toad paste. Take two toads, grind them up...' 'No, I get the picture.' Merlin stops the description.

'Horse dung. Crushed sheep's eyeball. 'Oh, lovely.'

'Pond scum. Three wolf spiders. And what potion isn't complete without a dash of sheep's brain?' Kara grimaces in disgust as Gaius finishes the list.

'Sounds delicious.' Merlin say sarcastically.

'Good, 'cause you're going to taste it.' Gaius says

'No way.' Merlin refused.

'It's completely harmless.'

'Er, no.' Merlin says but gaius gives him a look offering him the potion. Merlin keeps hesitation before dabbing a finger in. Kara watches in disgust as Merlin tastes the potion. He immediately gags, coughing.

"That is...ugh. That is disgusting.' He says wiping his tongue to get rid of the taste.

'Yes, to you, but not to a troll.' Gaius points out.

'I can't even believe you let me put that in my mouth.' Merlin gasps.

'Yes, well, try the original.' Gaius says and Kara looks at Merlin in pity

'Oh...' 'Just a small amount. And be sure to spit it out.' Gaius says and Merlin grimaces before he tastes it, immediately gagging and spitting it out.

'Does it taste roughly the same?' Gaius wonders.

'Yes! It's horrible.' Merlin says.

'Are you sure? Because if there's too big a difference, Catrina will notice.'

'It tastes exactly the same.' Merlin defends.

'Well, let's hope she thinks so, too.' Gaius says and Merlin grimaces again before taking the potion to go and swap the bottles.

Kara exited her small house, getting changed into a new dress for the day and having done a quick clean up when suddenly there's a loud commotion nearby. She walks forward to see two knights roughly holding an old man.

'What do you think you're doing?!' Arthur yells walking forward.

'He's refusing to pay the King's tax.' The knight explains.

'You- you ask for too much.' The man gasps, 'I've given all I can.,

'That's not enough!' The knight says and Arthur looks around seeing all the people staring at him imploringly.

'Let me see.' Arthur says and the knight hands him the gold. Arthur looks inside before passing it back to the older man.

'Release him.' Arthur says

'The King said...' 'Release him. Give them back their money. All of it.' Arthur says and Kara smiles along with the rest of the crowd. Arthur walks away servers people bowing to him as he does. Kara smiles happily before continuing to sweep the porch of her house.

Kara was walking by when she sees Arthur standing in front of the King and queen. She stops and mutters a quick invisibility speed slipping inside.

'I gave you a direct order.' Uther states.

'The people cannot afford to pay the tax.' Arthur defends.

'Don't tell me you're naïve enough to take them at their word?' Catrina says.

'We have their loyalty, their goodwill. Do not forsake that by making unreasonable demands.' Arthur says

'It it so unreasonable for a king to expect his subjects to obey him?' Catrina speaks and Arthur yells 'They'll starve!'

'Nonsense. They've grown too soft. Remember, these are your subjects, not your friends.'

'And why can't they be both?' Arthur points out

'Because we rule the people, not the other way around.' Uther says.

'I think you're wrong.' Arthur says shaking his head and Catrina turns to look at Uther.

'I beg your pardon?' Uther says walking forward

'I said you're wrong. Without the people there is no Camelot. We're as much their servant as they are ours.'

'You allow him to address you in this manner?' Catrina says appealed standing up.

'No I do not. It will not be tolerated. You will take your men down into the town and go to every house collecting the payments I demand.' Uther orders.

'I will not.' Arthur says defiantly.

'Get out of my sight.' Uther say and Arthur bows before walking away. Kara reappears down the corridor, proud for Arthur, happy that he was doing what was right instead of mindlessly obeying his father like he has done in the past. He'll make a great King, she thinks before she moves down the corridor.

She comes to Arthur's chambers and knocks on the door.

'Come in. Kara!' He says in shock seeing the girl, sitting up.

'I saw what you did earlier. The people owe you a debt of gratitude.' She speaks

'The people owe me nothing. My father's still going to impose the tax.' Arthur sighs.

'Is there nothing that can be done to change his mind?' She questions

'Not by me. He can't stand the sight of me.' Arthur says standing.

'That's can't be true. The King loves you, more than he loves anyone else'

'You should've heard the way he spoke to me.' Kara looks down, because she did yet she couldn't tell him that.

'Look I'm sure he was just angry, you're still his son. Everyone appreciates what you did. They know you tried, and they won't forget that.' She says trying to reassure him.

'Maybe he's right.' Kara shakes her head immediately but Arthur continues 'One day I will be the King of Camelot, and I cannot be a friend to the people as well as their ruler.'

'That's not true, and you will prove it when you become King. You have a kind heart, Arthur. Your a good man, Don't ever change. Not for anyone.' She says and he stares down at her.

There's a knock on the door and sir Leon enters

'The King has sent for you.' Leon states and Arthur leaves the room, Kara and Leon following behind.

The full council is assembled in the council chamber and Kara stands beside gaius.

'Father?' Arthur questions standing in the middle of the room.

'I'm relaxing your duties, revoking your title.' Uther states.

'What?' Arthur asks astonished. Kara glares at Catrina knowing that somehow this was the trolls doing.

'We live in dangerous times, I cannot allow you to undermine my authority.' Uther explains

'You've always welcomed my counsel in the past.' Arthur points out.

'You stood against me for all the people to see.'

'I'm sorry. Any future grievance I have will be held in private.' Arthur says but uther her shakes his head.

'No, it's too late for that.'

'Father, this is...' Uther interrupts 'You are to be disinherited, with immediate effect. You are no longer Crown Prince of Camelot.'

Gaius steps forward coming to Arthur's defence 'Sire, Arthur is your son, your natural heir...'

'Gaius' Arthur stops the physician gently before stepping forward facing uther 'You've always taught me to be true to my heart, and that's all I've ever tried to do. To be the man you wanted me to be. Someone you were proud to call your son.'

'My decision is final.' Uther says after a few moments and Kara watches as Arthur stares at him in disbelief before looking down. Arthur turns around and leaves. Kara wished she could go after him but knew that would only provoke suspicion and that would not be good, especially with the troll still alive.

'Queen Catrina will be named as rightful heir to the throne. The ceremony will begin forthwith.' Uther states, taking the paper. Sir Leon begins the slow clap, always being the respectful one of the Knights even when he doesn't approve of what the royals say.

Gaius and Kara sit in the physicians chambers, disheartened by the events. Merlin enter however with a wide smile on his face. 'We've done it! Catrina's drank the fake potion.' He cries before he sees their expression

'What's wrong? What's happened?' He asks.

'Uther has disinherited Arthur and made Catrina his heir.' Gaius explains.

'So if Uther dies, she will rule Camelot.' Merlin says and the two nod sadly.

Later in the afternoon, the ceremony of catrina's coronation begins. Kara stand by Morgana's side, Gwen next to her.

'We are gathered here to bear witness to the naming of Queen Catrina as the rightful heir to Camelot.' Kara glances at Arthur but he continues to look down.

'Are you willing to take the oath?' Geoffrey asks.

'I am.'

'Do you solemnly swear to govern the people of Camelot, to uphold the laws and customs of the land?' Kara watches as catrina's face drops.

'I...do.' The troll speaks itching at her arm. Kara smiles, knowing that the potion was wearing off.

'Will you, to your power cause law and justice in mercy to be executed in all your judgments?'

'I will.' She says before looking down at her arm seeing troll skin.

'Will you, to the utmost of your powers maintain the laws...'

'Yes, yes.' Everyone stares shocked

'I'm sorry, you-you must let me finish. The wording must be exactly right to be binding.' Geoffrey says,

'Well, get on with it then. I mean, really, where did you dig up this old crone from?' Everyone gasps at her words.

'She's right. Get on with it.' Uther says and there's talk among the people.

'Will you, to the utmost of your powers...'

'Yes, yes.'

'maintain the laws and customs...'

'I will, I will.'

'...of the land, and serve the people of Camelot?'

'Yes! Just shut up and give me the crown!' She yells and everyone stares shocked except for uther. Kara merely smiles catching Merlin eyes above.

Geoffrey present the crown 'Will you just hurry up! Catrina grabs crown and jams it on her head while running out of the Hall of Ceremonies.

'Catrina!' Uther yelled leaving. Kara followed as Morgana hurried after him.

They enter the council chamber and Kara grins as Merlin magically closes the door so Catrina can't escape.

'Whatever's the matter?' Uther asks,

'I'm sorry...' She says before she hides troll arm. 'I don't know what came over me. I, I just suddenly felt so hot. I, do you know, I think I need to be on my own, alright?' She says backing away.

'Are you alright?' Morgana asks.s

'Yes, yes, I'm, I'm fine. Really, thank you. I just...' She says turning back to the door.

'Fýrbendum fæst.' Kara mutters, locking the door with a quick smile.

'Come on. Come on. Open!' She yells, her voice cracking, her troll voice showing.

'Let me.' Arthur says walking forward but he catches a glance at the troll arm and backs away 'What's that?'

Catarina turns and begins to transform in front of them. Kara grins widely

'What's happening? Somebody help her!' Morgana says before the transformation becomes disgusting, Kara glances away catching merlin's eyes from behind a pillar.

'You're a troll!' Arthur yells, 'told you so' Kara mutters under her breath.

The troll gasps and uther's turns to look at him 'How dare you speak about her like that!' Everyone in the room turns and looks at him in shock.

'What is wrong with you? Look at the state of her!' Arthur says, pointing at the troll.

'I don't believe it.' Morgana gasps with wide eyes.

The troll rips open the door and Morgana and Kara move backwards. The troll glares at them before she exits with a snarl.

'She just ripped a door off its hinges. Doesn't that tell you something?' Arthur says.

'Enough!'

'She's a troll! A giant...grey...' 'Stinking' Kara supplies, 'Stinking troll!'

'Stop it! Haven't you hurt her feelings enough?' Uther says grabbing the crown and heels from the floor 'Insult my wife again, it'll be the last thing you ever do.' He says before fleeing. Arthur and Morgana continue to stare in disbelief while Kara mentally groans, so close.

Merlin flicks through one of his spellbook, 'it her must be enchanted. It's the only explanation.' Gaius says pacing. Kara nods from her chair.m

'Which is why we have to find a way to break it.'

'You won't find anything in your magic books. Troll enchantments are too strong.'

'Then what are we going. To do?' Kara asks.

'You must speak to the dragon. If there's a way to break Catrina's hold on Uther, he'll know it. But be careful, dragons and trolls have been close allies in the past.' Gaius says and Kara looks confused between the two,

'Dragon, what dragon?' She asks.

'You didn't tell her' gaius says surprised.

'I was waiting for the right time' Merlin defends,

'Tell me what?' She asks and Merlin goes into the explanation on how the last and the great dragon rests underneath Camelot, as uther's prisoner.

'Okay p, well I think you should definitely go speak to him then' she says after Merlin explains how many times the dragon has helped.

Merlin nods and leaves the chambers. 'A dragon' Kara says in shock.

'Indeed' gaius nods.

'The dragon said he had to cry tears of true remorse to break the enchantment.' Merlin explains having returned.

'Well, that's not going to be easy.'

'Easy try impossible' Kara states and gaius nods regrettgully 'yes, after all Uther's heart's closed to everyone.'

'Well, not everyone. Arthur.' Merlin points out.

'Then there's only one course of action we can take. Uther must see his son die.' Kara gales in shock and gaius words. Not liking this plan at all.

Gaius and Kara have now joined Merlin and Arthur in Arthur's chambers.
'So your great plan is to kill me?' Arthur states in disbelief. Kara crosses her arms sitting in a chair at the table, silent and pouting. She was being a child yes but she didn't like this plan at all.

'No. Well, yes. It...not exactly. It's...Gaius has made a potion that gives the appearance of death without the actual dying bit. It's fine. There's nothing to worry about. It'll only bring you to the brink of death.' Merlin says

'Oh, only to the brink.'

'We haven't got a choice.' Merlin states.

'We have to make your father cry.' Gaius explains.

'He doesn't care about me anymore.' Arthur says moving away from the wall.

'Nonsense. That's Catrina's influence. I've known your father for many, many years. There's never been anyone or anything he's treasured more than you. It's perfectly safe. A single drop of the antidote will reverse the effects immediately.' Arthur's eyes widen.

'Antidote. What antidote? You didn't say anything about the antidote!' Arthur yells at Merlin.

'Er...I didn't think it was important.' Merlin stutters

'The potion will lower your heart rate and breathing. For all intents and purposes, you will be dead.' Gaius explains.

'And the antidote reverses the effects?' Arthur questions

'Yes.' Gaius nods before adding 'If it's administered in time.'

'If it isn't?'

'You will be dead.' Gaius says bluntly.

'You just said it wasn't important!' Arthur yells at merlin who turn around.

'Erm...yeah, I suppose it is a bit important.' He stutters, shrugging. Kara rolls her eyes.

'Merlin will have the antidote. Once I have administered the poison...' Kara clears her throat when Arthur looks alarmed 'er, the potion, he'll have half an hour to get it to you.'

'Don't be late.' 'Am I ever?, Merlin questions 'yes' Kara says and he glares at her for the lack of confidence

Gaius goes to pass the bottle 'Are you sure you want to go through with this?' He asks and Arthur nods 'It's the only way to save Camelot.'

Arthur rolls his eyes and drinks the potion, waits, shrugs, then passes out. Merlin and gaius lower him gently to the floor and Kara walks over kneeling by him.

'Time to break the bad news to Uther.' Gaius says and him and Merlin leave while Kara stays by Arthur's side. She brushes his hair back and feels for a pulse, but it's pretty much impossible to find. 'I hate this plan' she mutters sitting back and watching the practically dead prince beside her.

The doors slam open and Kara quickly moves away as uther enters. He falls to his knees beside the pale Arthur 'my boy' he whispers.

'It was my fault. I pushed you away.' She hears uther say. Uther cradles Arthur to him and kara's head snaps to the side when the doors open and the troll walks in.

'My son. My son.' Uther chants brokenly.

'Come away. There's nothing you can do for him now.' She says and tried to pull uther away from Arthur.

'I killed him. I killed my only son!' The King cries.

'No, no, no, no. Nu meaht þú begalan. Nu meaht þú...' The Troll pulls on his arm and Uther finally turns around, tears streaming down his face.

'Catrina?' The red orbs glow disappears and uther stands up backing away horrified 'What kind of trickery is this?'

'How I've suffered these last weeks. Allowing you to touch me! Having to share a bed with you!' Kara feels like she's going to be sick at the troll's word and so does uther 'Ugh.'

'It's repulsive.' The troll says moving closer.

'I know the feeling.'

'Ooh, I've been looking forward to this.' She says

'Guards! Seize...it!' Uther yells. Kara watches as Merlin comes and kneels beside Arthur squeezing his neckerchief over his mouth. One small drop the anditote falls into his mouth.

The guards try to attack but are knocked down as soon as Arthur's awake he goes to attack but is knocked backwards.

'Is that any way to treat your dear old stepmother?' The troll grind before throwing Arthur into a wall. Uther attack but his thrown off along with other guards.

Jonas goes to attack Arthur but from behind him he hears 'Oi!' He turns to see Kara, only for her to run him through with her sword. The troll comes forward but the rug slips from underneath her and Arthur grabs a sword of his own stabbing the fallen troll in the chest. The troll makes several farting noises before dying. Kara gags covering her nose at the smell.

The next day Kara walks through the castle carrying a basket of laundry when she hears Arthur call out her name 'kara'

'Yes sire?' She asks turning around.

'I just wanted to... Ahem.. Apologise for not believing you about the troll business' he says awkwardly and Kara smiles.

'Apology accepted but maybe in the future you should listen to me more' she says and Arthur nods 'i will'

She smiles and the two stare at each other before Kara snows back to reality 'well I have chores to do. Have nice day my lord' she says with a bow before leaving because even though she may harbour feelings for the man, nothing could ever happen bet
