*Shout out to my Japanese readers! I'm going to Japan in 2018 to stay with two friends of mine - I can't wait! Thanks for reading and please favourite/follow/review!

Also, sorry if it seems like things are going a little slow, I'm just trying to set it up so I can make some big changes to the original events of s2 – thanks!*

Clarke marched through the camp, heading straight for the gate. Octavia and Indra flanked her either side, and the remaining grounders escorted Emerson behind her. Clarke knew that they cut a powerful path, and she was reassured to see people move out of their way as they walked purposefully to the gate.

Abby and Kane sat at a table outside the mess hall, night had fallen and they were discussing the upcoming journey that they were to make to Tondc tomorrow, where Lexa had returned with the leaders of the 12 clans, but as the commotion spread through camp they turned to see Clarke heading for the camp.

'They've got Emerson.' Said Abby in disbelief.

Jumping up from the table they intercepted her just in front of the gate.

'Clarke, what are you doing?' Asked Kane, blocking her path.

She ignored him, continuing to walk until Abby stepped in front of Kane. 'Clarke stop.' Her mother put out her hand and Clarke stopped walking, but she raised her head, staring Abby down.

'No.' She said firmly. 'I'm letting the prisoner go.'

'Absolutely not.' Exclaimed Abby, shocked.

'He hasn't told us anything yet.' Clarke turned to look at Kane as he spoke, and Ark guards took their place behind the council leaders.

'He doesn't have to,' Clarke's voice was resolute, bringing her eyes back to her mother's 'he's going to tell them something.'

'Get the prisoner back to the airlock, now.' Ordered Abby, but Clarke didn't flinch. As soon as the guards stepped towards her, the grounders behind her dropped into their defensive positions, unsheathing their weapons instantly, causing the guard to stop in their tracks. Indra's fearless glare alone was enough to stop many.

Abby eyed the scene cautiously, knowing that in hand to hand combat, the grounder's had the upper hand.

Clarke surveyed the scene as well before turning back to her mother. 'You may be the chancellor,' she said in a confident voice, 'but I'm in charge.'

Abby's face registered shock, but she still didn't move. 'Indra, tell your people to stand down, before this gets out of hand.' Abby ordered, not looking away from Clarke's defiant stare.

Clarke sighed, as though she had expected this, but showed no signs of being concerned in the slightest.

'No.' Indra's voice was dangerously low and firm.

'People could get hurt.' Abby said, and Clarke saw her begin to falter.

'Not if you get out of my way.' Abby blinked. 'You need to trust that I know what's right for us.'

Kane stepped closer to Abby. 'The grounders trust Clarke.' He said quietly. 'Maybe we should to.' He offered the girl a smile and Abby was taken back to what he had said, back in Lexa's camp, about them being run by a child. It was a bitter pill to swallow but Abby could see no way out of this. Kane had been right and now Clarke was right – she was in charge. Abby had deliberately blinded herself to it for as long as they had been on the ground, but it was inescapable. Clarke commanded more power and respect from her people than Abby could, with her Chancellor's pin.

'Stand down.' Abby said over her shoulder, after a long pause, and the guards complied. Clarke could hear the grounders lower their weapons in response.

Clarke stepped past her mother and Kane without another word. 'Open the gate,' she commanded, 'now.' Nodding as the metal doors slid open, Clarke walked until they were just outside the gate, before stopping and motioning for the grounders to bring Emerson forward. They positioned him in front of her and she leaned forward, her eyes so fierce that the mountain man felt them burning into him, even through his protective body suit.

'Can you hear me alright?' Her tone was mocking. 'Because I need to make sure you get this.'

'Loud and clear.' Replied Emerson reluctantly.

'I have a message for your leader.' Clarke spoke clearly and calmly, but her eyes flashed dangerously. 'We're coming for him. You're watching us but you haven't seen a thing. The grounder army is bigger than you think, and even if you could find it, your acid fog can't hurt them. And now, thanks to you,' Clarke reached into her jacket pocket and pulled out the small tone generator, 'neither can the reapers.' Emerson's stoic expression faltered and Clarke smiled dangerously as she prepared her final blow. 'So you have one last chance. Let our people go and we'll let you live. It's just that simple.'

Emerson attempted an easy smile, but he knew that Clarke could see the fear in his eyes. 'I got it.'

She reached forwards suddenly and he froze, but she didn't touch him, instead she seized the oxygen gage attached to the side of his suit.

'It's an eight hour walk back to Mount Weather?' She asked with faux innocence, already knowing the answer. He glanced down nervously, seeing that the gage read 'nine hours'.

Staring into the eyes of the man who had her friends' blood coursing through his veins Clarke held down on the oxygen release, listening to the soft scream of oxygen escaping. She watched the growing panic in Emerson's eyes as the needle on the gage dropped from nine to eight, seven, six.

'You're gonna do it in six.'

'Six hours? That's not enough,' protested Emerson, 'how am I supposed to deliver your message?'

Clarke merely smiled. 'That's your problem. Now go.'

With one last glance at the apparently fearless leader of the sky crew, Emerson turned and walked briskly away from Camp Jaha, towards the dark forest, Clarke's ominous message echoing through his head, and he realised she had been right – he hadn't seen a thing. He had no idea how much the strength the sky people had, because of her.

She watched Emerson's retreating back for a few seconds, before turning and stepping back inside the camp. She met Octavia's eyes and could see that the confident woman had something to say.

'Clarke,' her voice was low, cautious of being overheard,' you wanna explain how this helps my brother?' She wasn't questioning Clarke exactly, she just wanted to know what was going on inside her head.

'I just told them we have a secret army they need to worry about,' she smiled cunningly, 'the more they're looking at us, the less they're looking at him.' Octavia looked back at Clarke in understanding, and she felt hope spread through her. Clarke was right, and she would do anything to protect her brother, just as she would.

'Bellamy is the key to everything, Octavia, if he dies, we die.' Clarke's voice was thick with emotion and Octavia's pride for her brother was met only by happiness that he had found someone who loved him as much as he loved her.

Walking together with the grounders, they returned to the camp, even more spurred on to finalise their plans.

The next day and Clarke returned to the mechanic room, this was the third time today she had been in and she was starting to panic.

'Has he checked in yet?'

'No.' Raven replied sympathetically.

Bellamy was almost an hour late to radio, and she couldn't help but think the worst.

'He's late, what if something's happened to him?' Raven turned and saw the panic in Clarke's eyes.

'He really is your kryptonite huh?'

Clarke's eyebrows furrowed in confusion.

'It's from an old earth comic book story, the hero, Superman, was undefeatable, except when confronted with kryptonite – his only weakness. Bellamy is yours – I heard about you letting Emerson go. 'Fearless' was the word Octavia used, but as soon as Bellamy's at risk…' she trailed off.

Clarke smiled in understanding, and Raven's attempt to lighten the mood. 'I didn't know you read comic books, I had a few of them back on the Ark.' Her smile faded, 'I can't let anything happen to him, but you're right, I can't let him be my…kryptonide?' She tried to repeat the phrase but Raven laughed, telling her she got it wrong.

'Kryptonite, but close enough. He'll be fine.'

The two women smiled at each other and Clarke made a note to appreciate Raven more, not only was she incredibly smart, but she was insightful too.

Clarke's eyes wandered to the notes strewn across the room. Written on the large, clear boards scattered around the room were dozens of diagrams, numbers, equations, and formulas that meant little to Clarke, but were obviously of great importance to Raven. The diagram closest to Clarke showed the dam that powered Mount Weather, covered in Raven's looped writing.

'You've been busy, why are you focusing on the dam?'

'I know you wanted to concentrate on the acid fog, but until Bellamy get eyes on their dispersal system, there's only so much I can do.' Clarke nodded tersely, accepting Raven's point.

'Okay, tell me about the dam. Can we cut off their power?'

'Maybe. I'm still playing with a few things.'

Suddenly the radio crackled to life and Bellamy's voice filled the room. 'Work station, do you read me?' Clarke rushed to the radio, Raven following. 'Anybody there?'

Grabbing the mic, Clarke raised it to her lips 'Bellamy you're late.'

Bellamy almost laughed out loud. Clarke was worried, and she was mad that he had made her worry.

'Every three hours means every three hours.'

'Are you through?' He said teasingly. There was a pause and he could picture Clarke breathing out, calming herself. His heart ached.

'Have you found the source of the acid fog?' She asked, her voice calmer.

'No, but that's going to have to wait.' Bellamy's deep voice had become serious again.

'What? No…'

'Our friends Clarke…they've started taking them from the dorm. One at a time, every few hours.' Clarke's stomach dropped. She couldn't talk.

Seeing her expression Raven leant forward, squeezing the mic around Clarke's hand. 'Taking them where?' She asked.

'I don't know.' Bellamy replied, his voice heavy. 'We tried to follow them but they went to a classified level. Maya borrowed the schematics of the vent system from her boss, and we're still trying to find a way in.' He turned to where the girl was pouring over the sheets of paper. 'Anything?' He asked her.

'I think I've found a path, but it's going to be tight. Here's the walkie Raven asked for, and the ear bud.'

Clarke heard Maya's faint voice and turned to Raven curiously.

'We're going to make a mobile, so he can talk to us from anywhere.'

Clarke nodded, impressed.

'Bellamy,' her voice was thick with emotion again, and Bellamy closed his eyes, 'you have to find them.' She implored.

'That's the plan.' His voice was gravelly.

'I have to go,' she said carefully, ignoring Raven's surprised glance, 'stay safe.'

'You too.' He clenched his fist and when he opened his eyes he knew she was gone. Maya watched him carefully, surprised to see the stoic man show such emotion, but she looked away as he turned to face her.

Within an hour Raven had talked Bellamy and Maya through making the mobile, and Bellamy was crawling through a maze of tight vents on his hands and knees. His limbs were aching and his shirt clung to his back. As the sweat dripped down his face he cursed silently for the hundredth time, trying to ignore how closely the vents resembled the claustrophobic cage he had been held in.

Raven's voice in his ear distracted him, 'tell us where you're at now.'

Us. Clarke was there. Steeling himself, Bellamy used the knowledge to push himself forwards and, miraculously, it worked.

'I'm at an intersection,' he replied, looking around the metallic vent system, 'which way?'

Clarke and Raven looked to the large diagram of the mountain that they had drawn up. 'He just passed the air filtration system on this floor,' said Raven, pointing to a level on the diagram, 'which puts him about here.'

Clare took the mic. 'Bellamy, we think you're close,' his heart picked up at her voice, 'the lab should be up ahead.'

'Any chance you can be more specific?' Clarke could hear the smirk in his voice, but she knew he was concerned.

Bellamy looked at the three vents in front of him, wondering which one to pick, when the sound of a drill reached him, coming from the right hand passage. Feeling his skin crawl, he followed the noise.

'Never mind.' Bellamy said grimly, and Clarke thought she heard drilling come from the radio.

The drilling got louder the further he crawled, and all three of them winced. After a few more seconds Bellamy rounded a corner and came to the large fan at the end of the vent. What he could see through the spinning blades made bile rise up his throat.

He knew Clarke had figured out what he was looking at as her voice came over the radio.

'Bone marrow extraction.' She said, horrified.

Before he could reply the woman in a white lab coat wielding the drill stopped, silence falling over the small room she was in. She stood next to a medical bed, drilling into the body of a member of the 100, Bellamy recognised him but couldn't remember his name, something beginning with T. Swallowing roughly, he watched as the female doctor, a petite woman with light brown skin and black hair, replaced the drill with a large syringe and embedded it into the thigh of the young boy lying on the table, before extracting his bone marrow with a sickening noise.

Turning from the boy's dead eyes, Bellamy followed the doctor's gaze as it landed on another man, a guard, sat on a chair on the other side of the room. A man in a light grey suit, his dark hair slicked back from his face, stood next to him. She crossed over to them as she spoke, walking past two rows of cages, identical to the ones they were holding the grounders in, the one he had been held in. 'Are you ready for the last treatment you'll ever need, Lieutenant?' Her voice was deceptively gentle.

'You have no idea,' the man's voice filled the radio and Clarke's eyes widened. 'I've waited my whole life to breathe fresh air.'

'That's Emerson.' Clarke said, shocked.

The suited man uncrossed his arms. 'Let's get back to this secret army she claims to have?' Clarke's ears pricked. 'Did she tell you anything that might help us find it?

'No sir, nothing about the army. She did say she was coming for you, and that if we let her people go, she'll let us live.'

Bellamy's mind whirred as he put the pieces into place. This was the man that Camp Jaha had captured, Clarke and Raven had told him a little about what had been happening whilst he was in the mountain.

'Well it's a little late for that.' The man in the suit said uncaringly, glancing into the furthest corner of the room where Bellamy saw another body on a bed, covered by a blue medical sheet. An arm hung off the edge of the bed though, and it was free of tattoos, meaning it wasn't a grounder, it was one of their friends.

Thinking back to what Maya had said, he offered a quick prayer that it wasn't Monty.

'Whitman just radioed in,' continued the suited man, 'apparently there's a war council meeting happening tonight in one of their villages. All their leaders are going to be there.'

'Sir I feel good,' Emerson's voiced filled the radio again, 'let me take a team out, support Whitman.'

'No, he has less chance of being spotted if he's on his own.'

'Sir, Whitman's good but he can't take out that many targets alone.'

Clarke held her breath. As Bellamy watched, the suited man smiled coldly.

'That's why we're going to use a missile.'
