*Shout out to my readers from Austria, Belgium, Denmark and the Netherlands, all countries so close to home but one's I have to visit – hopefully I'll get there soon! Thanks so much for reading and please favourite/follow/review! Also, I'm sorry for shifting Lexa's character into such an unfeeling one, I was considering writing in a love triangle, but decided against it. I hope nobody takes offence in light of what happened in Season 3*

*Also, I completely forgot to say, but I have a twitter dedicated to The 100/Bellamy/Bellarke and I'd love it if you followed me! I follow back!*

Clarke looked into Lexa's eyes and felt cold despair wash over her.

Emerson stepped forward, and when he spoke his voice was self-satisfied. 'You made the right choice commander.'

It took everything in Clarke's power not to launch herself at the man. Instead, she made sure that all of the hurt, and betrayal, and grief that she was feeling shone in her eyes, and she was pleased to see Lexa flinch away from the sight.

Emerson slunk back inside the mountain, as Lincoln came to stand at Clarke's right hand side. 'What is this?' He said lowly, fearing that he too knew the answer already.

'The commander made a deal.'

'What about the prisoners from the Ark?'

'They'll all be killed.' Clarke answered before Lexa could, blinking away tears. 'But you don't care about that do you?' Clarke said, staring murderously at the commander.

'I made this choice with my head, not my heart. The duty to protect my people comes first.' Replied the grounder, and Clarke felt the last sliver of hope she held die.

'Don't do this.' Clarke cursed herself for begging, but she had to something, her friends were in there, Bellamy was in there.

'I'm sorry Clarke.' Intoned Lexa again coldly.

'Commander, not like this,' pleaded Lincoln, 'let us fight.'

'No, the deal is done.'

At Lexa's words, the door to the mountain was pulled closed, shutting out the rest of the light spilling out into the clearing, closing Clarke off from the rest of her friends, sealing off the only entrance.

At Lexa's orders, a grounder next to her sounded the horn, signalling their retreat and Clarke's eyes filled with hot, angry tears, watching the grounder army leave.

'You too,' Lexa said to Lincoln, 'all our people withdraw, those were the terms.'

He barely even hesitated before responding. 'They'll be slaughtered, I have to help them.'

'Take him.' Ordered Lexa in Trigedasleng and two grounders seized Lincoln. He fought them off but two more came, and two more, and eventually he was subdued. He looked up at Clarke with apology in his eyes but she shook her head. He had nothing to apologise for.

Dragging Lincoln away with her Lexa turned and walked away without another word, and Clarke stood, watching her go whilst feeling her world crumble to the ground around her.

Raven and Wick crawled to each other through the rubble of the explosion, coughing and panting. But as soon as they reached each other armed guards appeared, surrounding them and hauling them to their feet.

'Wick.'

'It's gonna be ok Raven.'

The guards marched them from the dam, back into Mount Weather and they went, without another word, their fate hanging over them heavily.

In the tunnels, Octavia stood, peering into the door, desperately waiting for Bellamy to arrive so that they could get him and the rest of their friends out of there. But before he could, they heard the sound of the horn being blown faintly.

'We're retreating.' Indra said, her expression puzzled.

'That can't be right.' Protested Octavia, equally confused.

'We have to go,' ordered Indra, 'now.'

'Indra, wait. They're still in there.'

'And our commander's out there, under attack for all we know.'

'I don't trust her.' Octavia said boldly. 'Not after Tondc, and neither should you.'

Indra's eyes narrowed. 'I gave you a direct order.'

'Please, this was the plan. If we're not here with the tone generators when they come out, reapers-'

'Plan's change.' Interrupted Indra.

'Octavia, let's go.' Pleaded a young grounder whom Octavia had been working with, but she ignored her.

'I'm not going anywhere without my brother.' She said, her voice steady.

Indra's stare darkened, and she drew a dagger from her waist, holding it against Octavia's throat in a second. 'You are no longer my second.' Indra said, and Octavia almost flinched away from the disappointment and betrayal in her eyes. She gasped as Indra pulled her dagger away, nicking her neck and drawing blood, but she didn't look away.

Jackson approached her side, 'Octavia, please, come home with us.'

She didn't even look at him, he could run away, but Bellamy needed her. 'I have no home.' She said firmly, blinking away tears.

Jackson sighed, shrugging off his rucksack, 'you'll need this' he said, dropping it on the floor lightly before turning and following Indra and the rest of the grounders and sky people.

Inside the mountain, Bellamy, Maya, Jasper and Monty burst into the harvest chamber. It was empty, and deafeningly silent, until Maya's eyes landed on the body of her father, lying in a pool of blood on the floor. He had obviously died trying to protect their friends when the guards came looking for them.

'No!' Screamed Maya, running to the body. 'No!' she dropped to her knees sobbing over the body of her father as Jasper comforted her, but Bellamy couldn't tear his eyes from the rows upon rows upon rows of hundreds of empty cages. The grounders were gone. Their hidden army had abandoned them. His heart sunk to the floor and he closed his eyes as Maya's sobs made his chest ache. His mind raced, trying to figure out what had happened, but one thought became clear - he had failed them, and now they were all going to die.

Clarke stood facing the door, her mind surprisingly calm, considering the man she loved had just been sentenced to death inside a mountain, along with at least 40 of her friends.

'Clarke, let's go,' called Miller's father as he shepherded the rest of the Ark guards away from the mountain to return to Camp Jaha, 'we'll come back with reinforcements.'

She didn't acknowledge him, knowing that they would never have time.

'Clarke?' Monroe called her now, 'Clarke, come on.'

She turned to face her, her face a stony mask. 'It's over, I'm sorry.' Monroe said softly, thinking of Bellamy, trapped inside the mountain, and how heartbroken Clarke must be.

Clarke watched her leave with others before turning back to the door, completely alone.

'It can't be over' she thought, and just like that her mind kicked in again. Her mind had done so much, saved so many lives, and come so close to taking down the mountain, she knew she could use it to save Bellamy and the others.

Octavia sat against one of the large metal skips that were propped against the side of the tunnel. They were pushed underneath metal chutes that Clarke had told her she and Anya had escaped from, that they were rubbish chutes, only for the grounders when they had drained all they could from them. Trying to shake the thoughts away Octavia felt nausea bubbling as a buzzer sounded and something dropped from the chute into the skip. Standing up warily, she peered into the chute to see the body of a young girl, covered in cuts and bruises, dripping with blood. Octavia swallowed hard as she looked at the girls face. 'Fox.'

Before she could mourn the girl, footsteps echoed from further in the tunnels, they were running. Grabbing the large knife from her waist she stepped forward defensively, gripping a tone generator in her hand, preparing to face the reapers. But it wasn't a reaper who rounded the corner.

'Octavia.'

'Clarke.'

'You stayed!' Clarke felt the closest thing to happiness she could under the circumstances.

'Of course I stayed.' Said the girl, pulling Clarke into a quick hug.

'We have to get in there.' Said Clarke, rushing to the door, but she stopped dead when she saw Fox's body in the skip.

'Why did Lexa sound the retreat?' Octavia asked, drawing Clarke's attention away from the body of another of their friends.

'She made a deal with the grounders,' Clarke said brokenly, 'she freed the grounders and then she left. Now we're on our own.'

'She betrayed us.' Octavia growled.

Clarke began hammering on the door.

'Stop!' Yelled Octavia. 'They'll know we're here!'

Clarke spun away from the door, adrenaline coursing through her veins. She grabbed the gun from her waistband and aimed it at the control panel at the side of the doors to the mountain.

'What's wrong with you?' Octavia gasped, pulling Clarke's arm down.

'I am getting through that door.' She yelled frantically. Her mind was racing and her pulse couldn't seem to catch up. Somewhere inside she knew she wasn't thinking straight but she had to see him.

'And that's your plan?' Octavia tried to calm her down. 'Bellamy's counting on you. We're all counting on you.' Clarke could see that Octavia wanted to say more, but she stopped herself. 'What about Lincoln?' She asked quietly. 'There's no way he would have gone along with this.'

'He didn't.' Clarke hesitated. 'I'm so sorry Octavia, they took him. But we're going to get him back.'

The girl nodded, blinking away tears. She had lost him so many times, she couldn't let this be the first time she didn't get him back.

Before they could say anything else the control panel next to the door beeped once and the door began to open. Instinctively the two drew their weapons, Octavia dropping in to a crouch. Clarke glanced at her out of the corner of her eye and was struck but how fearsome she looked, how strong, before she pulled her eyes back to the door. Standing there, in the doorway, was Bellamy.

Everything seemed to freeze as her eyes scanned his strong shoulders, his tousled curls, and finally, his deep eyes. He stepped into the tunnel and in seconds she had closed the gap between them, throwing herself into his arms.

'You're ok,' she gasped, her lips brushing his collarbone, her warm breath making his heart stutter, 'you're ok.' Breathing in she filled her lungs with him, it was only fair since she had already drowned in the sight of him.

Bellamy wrapped his arms around her tightly, comforted to find that she still fit perfectly in them, and dropped his head, burying his face in her hair. She was here. She was really here. Night after night in the mountain he had dreamt of her, dreams coloured with gold and blue as she whispered to him, lying safe beside him.

'Clarke.' He sighed, and the sound sent a shiver coursing down her spine.

She threaded her right hand through the curls at the back of his head and felt his shoulders relax slightly.

They stayed like that for a few more seconds, wrapped up in each other once again, before Octavia cleared her throat. They reluctantly stepped back, aware that they could have stayed like that all day.

Standing behind Bellamy were two faces that she had missed more than she thought possible.

'Clarke!' Jasper flung his arms around her, and seconds later Monty had done the same, enveloping them in a group hug.

'I'm so glad you're ok.' She whispered emotionally.

'We're fine.' Monty reassured, although his smile didn't quite reach his eyes. Clarke was reminded once again of the horrors her friends had already faced, and what was still to come.

After another moment or two, Clarke's eyes found one more figure stood unsurely in the doorway, a young girl in a hazmat suit.

'Thank you.' She said to Maya sincerely, and she was rewarded with a smile. She owed her Bellamy's life, and that meant more to Clarke than she could ever express.

Turning back to Bellamy she confirmed everything he feared in a glance. They were alone. He didn't press her on what exactly had happened, the pain in her eyes was enough to dissuade him. Besides, it was clear that Lexa had abandoned them, he could find out the details later. For now, he and was going to rescue his friends with Clarke and his sister, the two most important people in his life.

'We need to go find Dante.' He said firmly and she nodded.

Turning, the six of them stepped back into the mountain, together.
