A/N Hi! This will be my first full length 100 fanfiction, it's my version of Season 3, and however it mostly revolves around Bellamy and Clarke, which is never a bad thing! I've written the next couple of chapters that depending on how you all respond to this sort of tester chapter will be going up over the next couple of weeks.

Thank you, and please enjoy!

The moment haunts him in his sleep. He just let her walk away, and his conscious is never going to let him forget it. Every night he's presented with a new horror. Last night, it was a mutant dog mauling her to her own, tortuous death. The night before that, her body concaved from lack of food as slowly she became withered down to the bone. But the night before that, it wasn't a horrifying nightmare he was subjected to. It was a memory. A memory that had been placidly resting in the deepest, darkest crook of his mind, pushed back by his survival instincts, growth of ego and simple stubbornness. It was the first ever time he saw her, and not on the dropship. He can't believe that he allowed himself to forget.

Although being a janitor wasn't exactly the most glamourous job on the Ark, it was enough to earn the extra money Bellamy need to feed and care for Octavia. Some days, days like today, when his temper was short and stomach rumbling, it became increasingly hard to ignore the disapproving stares he received from passers-by in the corridor that found it funny to roll their eyes, turn their noses up and even offer a few sniggers here and there at him. He never like sweeping this part of the Ark: all the people here thought they were better than everyone else on the goddam ship. People like them frowned upon people like him, which never made any sense. If it wasn't for his people, the upper class would be walking around a dirty ship, eating of sticky plates and be wearing wrinkled clothes. God forbid. Bellamy swore that if he was ever stuck in a confined space with one of the privileged, he would find it hard not to knock them out.

It seemed that a few wayward kids, probably of all whom who had parents on the council, thought it would be funny to knock Bellamy's supply trolley over, letting the contents of lemon-scented bleach and rolls of tissues spill across the floor. He let the giggles escape with them as the jogged away, giving each other high-fives on the way while he fought the urge to go after them. Sometimes he wondered, if Octavia was a part of the privileged, or ever given freedom, would she be a reckless and carefree as some of the kids around here? He hoped not; trying to keep her alive is hard enough as it is. Without anything but an unamused grunt, Bellamy bent down and started gathering the mess of supplies. Soon, he heard two voices approaching, and suddenly blood rose to his cheeks and the sweat coming from his hands became apparent.

"I just don't see why biology is important." A deep boy's voice said, that Bellamy didn't even have to look up to know who it was. Wells Jaha: son of the Chancellor. Despite the fact that Bellamy was from the rougher part of the Ark, he was still educated enough to know who was in charge, and that made Wells Jaha a famous face.

"Because," His female friend with a melodic voice said. "If you know the human anatomy it makes it easier to save someone, not to mention that when-"

Bellamy looked up when the music stopped. Wells Jaha and his friend had stopped talking, and now both stared at the catastrophe that was Bellamy Blake clearing up the mess done by a group of ten year olds. The last thing he wanted to do was make eye contact with either of them, but he couldn't resist looking at the girl's face. She had a youthful glow similar to Octavia's, so Bellamy guessed that she couldn't be much older than his little sister. The girl was unfamiliar; he had never seen her on the Ark before, which was rare since there were only about 2,000 people. Her blue eyes splashed with sorrow when she took in the scene in front of her.

"Oh my god!" She exclaimed, her pace quickening as she moved towards him and set the trolley back on its feet. "Let me help you."

"Clarke." Wells Jaha said, along with a look Bellamy had now seen one too many times. "It's his job, let's go."

"No." Clarke looks up at him. No way could this girl be privileged. "He needs help so I'm going to help him, what's the problem?"

"It's what he's paid to do, it's not fair for him to get paid if he's not doing anything. It's defying the system."

"No, defying the system is breaking the law." Like having a second child, Bellamy thought to himself as Wells Jaha and Clarke argued about him as if he wasn't here with them. This must have been how Octavia felt. "Not helping someone."

"Clarke." Wells Jaha sighed as his irritation began to show. "Let's go."

"You go, I'll catch up." Clarke didn't look up, but instead grabbed some bottles that had rolled to the wall. Mumbling something, Wells Jaha walked off, leaving Bellamy in an intense silence while he and Clarke continued to fix the mess he'd made.

When everything was back in the trolley, Bellamy realised he hadn't even uttered a word to Clarke yet. "Thanks." He said, offering her a small quake of his lips.

"It's not problem." Clarke's smile was a lot more confident than his. "I'm a klutz as well."

"Really?" Bellamy managed a smirk. He was more relieved that Clarke didn't know the trolley incident was a work of kids than when Octavia didn't scream when she was born.

"Yeah." Clarke chuckled, leaning her back against the cool, metal wall opposite Bellamy. "Sorry about Wells, he's big on following the rules."

"It's okay." He shrugged off the lie. "I know it's frowned upon to socialise with people like me."

"I try to be different." A blush had crept onto her young cheeks that matched Bellamy's. "When we're on the ground, it'll be different. Everyone will be so scared of dying they'll forget their differences."

"I like that idea."

One of few times, Clarke was wrong, but one of few times, he wished that she was right. If what she said was true, and everyone forgot their differences in the dropship, they wouldn't be in the situation that they're in now. Charlotte would be alive. Murphy wouldn't be so full of hatred. Wells wouldn't have died. Finn wouldn't have massacred a village. Raven wouldn't have had her heart broken and a hole shot through her spine. Harper wouldn't have been harvested. Octavia wouldn't feel the need to be accepted by a grounder clan. Monty wouldn't have had to become the leader of the 46 trapped in Mount Weather. Jasper wouldn't have lost his first ever love. Bellamy would have been nicer to Clarke. Clarke would still be here.

But she made him promise one thing before she left, and he was going to be loyal to that, whether it be the last thing he did: he would not break his promise to Clarke Griffin.
