They didn't choose each other, it just happened
They hated each other, they were opposites, he wanted chaos and she wanted order. He was winning.
Then the acid fog came, and he realised the camp needed her.
That's when the looks started, they didn't need to talk to understand each other, and just a look would do.
After charlotte they started to fight a lot more than normal, but they understood each other more.
Then raven arrived. Clarke shut herself away from him, too embarrassed to face him. He gave her space but also stopped the rumours from spreading and kept Finn away from her.
They changed that night, when they tortured Lincoln. They both became harder. They knew how far the other would go to protect their people and their home and it calmed them. They trusted each other completely.
After that the touching started, it was only to comfort each other at first the occasional shoulder or knee squeeze and suddenly it was whenever they where near each other a hand on a back, shoulder, waist. And sometimes they held hands when they thought no one would notice just for the comfort of knowing they weren't alone.
Bellamy hadn't slept with anyone since Roma died and Clarke hadn't slept with anyone since Finn.
They started looking out for each other, bringing the other water/food just when they had free time or spare rations.
Clarke made him a sword out of a deer hind leg bone.
Bellamy made her a hair comb out of oak.
After the grounder attack left everything in ashes they decided to build sturdier homes.
Bellamy made sure the first thing built was a new medical bay for her.
Clarke asked Octavia to come back, because Bellamy missed her.
When the ark survivors found them Bellamy and Clarke didn't let them into camp. They had worked too damn hard on their home just for it to be taken over by the people who had left them to die. They tried to force their way in. Tried.
That night he found her in his bed and the next day she moved her stuff into his hut.
Bellamy beat anyone who suggested they were fucking, just to stop people from assuming; it wasn't any of their business if they were or weren't.
She was sat in a chair, they'd come a long way in carpentry, with Bellamy stood behind her when she met her mum. The end agreement was that the two groups would stay separate, close to each other location wise but separate. She didn't forgive her mum but agreed to share information to help them survive. Bellamys hand didn't leave her shoulder the entire time.
Finn cornered her, kissed her begged her to give it one more go. After she said no he kept trying to kiss her so she left him with a black eye and bloody nose.
Bellamy watched the transaction from afar and smiled when she made eye contact, she walked determinedly towards him and kissed him before he could speak, it was their first kiss in front of people. The entire camp cheered and a party was thrown just for the occasion.
The original 100 called them mum and dad to their faces now.
A different tribe of grounders attacked. They didn't stand a chance against them now. They were stronger; more protected and had more people.
Eventually the two camps merged into each other, it was just easier.
Bellamy and Clarke were still in charge. They didn't give the old council a chance to have any control. Not that anyone complained.
When Clarke became pregnant Bellamy had a school built.
A boy named Lincoln.
Two girls named Charlotte and Raven
They were a family.
They didn't choose each other at first, they never said the words out loud, but when Abby suddenly died she told him.
"No one else but you"
"No one else but you Princess"
