the grounder's eyes were still throwing daggers at arabella. 

"nyko? is it true?" octavia asked, a stern look on her face.

"yes. death is the only way." nyko replied quietly

"hold on. there could be a way to bring him back." clarke tried to reason with nyko.

"none that i've ever seen." nyko said. 

suddenly, finn shoots up the dropship ladders. arabella's eyes widen.

"we have to go. the camp's leaving." finn told the group.

"you!" nyko yelled, immediately jumping to his feet, charging at finn, grabbing him by the collar slamming him into the wall. "ripa!" he shouted.

"get off him!" bellamy yelled, his gun raised at nyko

"you slaughtered my people. elders. children. innocents." the grounder shouted to finn.

arabella stood in shock at the scene unfolding in front of her. but she wasn't about to risk her life, especially for finn.

"nyko. you're killing him." octavia called out to the man. 

"blood must have blood!" 

"get out of the way." bellamy said to octavia. 

arabella and octavia stand in front of his gun. "bellamy, you're not shooting him! no!" octavia shouted to her brother. 

"move!"

"bellamy! stop it!" arabella snapped, yanking his gun away from him. "not a chance!"

"arabella!" bellamy scolded the girl.

everything unfolds too quickly, clarke runs at nyko jabbing the electric baton into the man's ribs. nyko drops to the floor with a yell. everyone is heavily breathing, arabella and bellamy are staring at each other and nobody else. 

the couple's gaze on each other is so intense everyone else in the room can feel it. they daren't break eye contact, as if it's some competition to who looks away first loses. arabella blinks once, then twice, and finally looks away from him.

arabella and octavia look at lincoln to see that he's not even moving. "lincoln." octavia whispered, she rushed down to his side. "he's not breathing." 

"clarke, do something." arabella muttered loud enough for the group to hear. 

clarke knelt down to octavia and put her fingers to his neck. "his heart's stopped. move." she said to octavia. clarke begins performing cpr on lincoln. 

arabella watches, because that's all she can do. she feels a hand link with hers, the girl doesn't need to look to know it's bellamy's hand she's holding. she gently squeezed his hand, glancing up at him with sadness. 

there were a few moments of silence while clarke preformed cpr, then, finally, lincoln inhaled a deep breath. octavia looked over at arabella with relief.

"he was dead." nyko spoke. "how did you do that."

"it's called cpr." arabella said sassily and crossed her arms over her chest.

"you've tried bringing reapers back before?" clarke asked.

nyko just nodded. 

"and they died like this?" clarke questioned the man, making the man nod again.

arabella saw clarke was thinking. "clarke? what is it?"

clarke looked up at arabella. "i know how to stop the attack."

"you're gonna bring the reapers back?" arabella trailed off, looking up at clarke in surprise.

...

clarke and finn had rushed off back to camp jaha to stop the evacuation. meanwhile, arabella, bellamy and octavia had been left at the dropship with lincoln and nyko.

arabella and bellamy were stood outside of the dropship. stood in silence until arabella finally broke it.

"i'm sorry for yelling at you... again." she told him, looking up at the man.

bellamy met arabella's eyes. "i know." he spoke quietly.

"i'm just sick of death." the girl confessed, turning to face bellamy. "people are dying every single day and it's becoming too much. if i witness anyone else die i may just lose my mind." she let out a small humourless laugh.

bellamy sighed, pulling arabella into a hug, his chin resting on her head. "i know, sweetheart."

arabella looked up at him again. "don't hate me." she whispered.

"i love you, bella. i could never hate you." bellamy told her, holding her face with his hands, placing a soft kiss onto her lips. 

arabella blushed, her arms wrapping around his shoulders. "i love you, bellamy blake. always."

a while later, finn popped up from the ladder.

"thank god." arabella spoke with relief. "wait, where's clarke?" she asked.

"trying to stop a war." finn responded. 

abby griffin climbed up the ladder, her gaze landing on arabella, then lincoln. the woman knelt down and opened one of lincoln's eyes. 

she let out a sigh. "pupils are unresponsive." abby rummaged through her bag. "tie off his arm. tight as you can." she told octavia. 

"thanks to the supplies your brother found, lincoln might have a chance." the woman spoke, she picked up a vial and a needle.

"what's that?" arabella spoke from behind abby.

"it'll bring down his fever." she replied, injecting the needle into lincoln's vein.

but just as abby broke skinn, lincoln moved and began moving against the restraints.

"hold him down!" abby ordered. 

arabella, bellamy and octavia helped hold lincoln down so abby could help him. "you just gonna stand there, finn?!" arabella yelled. 

finn came over to help, nervously glancing behind him at nyko.

abby managed to inject the liquid into lincoln but then he went silent and stopped moving, the woman put her fingers to his neck.

"what's happening? why isn't it working?" octavia asked, looking up at abby in worry.

"his heart stopped." abby replied. 

arabella and bellamy stood up, unsure on where to place themselves. nyko came over and knelt beside lincoln whilst abby prefromed cpr.

"you're their healer?" she asked. "tilt his head back. pull his chin down to open his airway." 

abby continued cpr but it wasn't working. he was gone. lincoln was dead. arabella let out a sigh, she turned to bellamy placing her head into his chest as he wrapped his arms around her. 

"you're stopping. what's wrong?" octavia's pained voice spoke up. 

"i'm sorry." abby whispered. 

arabella slipped away from bellamy and walked over to octavia. 

"he's gone." the older woman said. 

"no, it's not possible. you're wrong!" octavia moved abby away from lincoln and began cpr on him herself.

"o." arabella whispered. "octavia."

the younger girl ignored arabella, tears streaming down her face, small sobs escaping her mouth. "come back." she cried. 

the hatch to the ladder opened up, clarke's blonde hair popping up. all their heads turned to the girl.

arabella and bellamy were at either side of octavia as she cried for her lover. arabella placed her hand on the girls back, octavia fell into arabella's arms.

"you're okay." arabella whispered, stroking the girls hair as she cried. 

arabella turned her head to see grounders in the dropship. she looked down and saw the electric baton by her feet. she pulled her brows together, thinking, hoping and praying that the electricity would work. 

bellamy slowly reached for his gun. 

"i'll kill them all." one of the grounders spoke, her voice menacing. 

everything happened in a blur. the grounder pulled out her sword, bellamy rose his gun and arabella grabbed the baton, extending it and holding it up to defend herself since her gun was too far away. 

"this does not need to happen." arabella spoke, looking at the grounders. 

"shut up, sky girl!" the woman from before yelled.

"please. you don't have to do this." clarke said to the other grounder, this one looked a lot younger though. 

"you lied." the woman replied. "and you're out of time."

arabella looked at the baton in her hand, her heart pounding in her chest. a second later, she ran to lincoln's side and slammed the end on the baton onto his chest, right on his heart. the electricity hummed loudly. lincoln's chest arched up for a moment before falling down again. "lincoln, come on!" arabella yelled.

"hit him again." clarke told her.

arabella hit his chest again and this time lincoln gasped loudly, breathing for air. the man gasped as his eyes opened. arabella smiled with relief, throwing the baton across the room. 

octavia crawled over to lincoln. "oh, lincoln." she whispered as the man looked at her. 

arabella stood up and looked at the younger female grounder, her mouth was slightly agape as she looked at lincoln. 

"octavia." lincoln whispered, his voice weak.

the younger girl let out a sigh of relief.

the grounders put their swords back into their holders, arabella backed up to bellamy and gently took the gun from his hands and placed it on the ground.

... 

everyone headed back to camp jaha, lincoln was going to stay with them while he recovered. the evacuation had thankfully stopped too, so everyone was still at the camp. 

arabella watched as jaha walked over to her, she tried to conceal an eyeroll, but failed.

"miss kane." jaha spoke.

arabella grimaced. "jaha." 

"i just wanted to make you aware that... i was with your father when he went to attempt to make peace." he began to explain.

arabella's face hardened. "and where is my father now?"

"i do not know."

the girl stepped closer to him. "so you left him? you left him to die?!" she yelled.

arabella felt a hand on her shoulder, she spun around to see clarke. "the commander wants to speak with us." 

arabella closed her eyes for a moment, sighing in annoyance. she turned back to jaha. "for the sake of your life. he better come back." she spat and followed after clarke. 

...

arabella and clarke arrived at the commanders tent, they had earned probably a thousand glares from passing grounders. 

"lincoln's recovery was..." the commander, lexa, spoke to the girls. "impressive." she glanced to arabella with a nod. "no one's ever survived such a fate before." she smiled, almost shocking arabella. 

"it's not complicated, really." clarke told her. "we just have to keep them alive long enough for the drug to leave their system. i know we can do the same for others." 

lexa nodded and looked at arabella and clarke. "you may have your truce."

arabella and clarke looked at each other with a smile. "thank you." clarke smiled to lexa. 

"i just need one thing in return." 

"tell us." arabella nodded with a smille.

"deliver me the one you call finn." lexa said simply. "our truce begins... with his death."
