17 year old Haley griffin was put in the sky box when she was 8. Until then she was hidden in the walls. On the ark you could only have one kid and Haley's father wasn't supposed to be born. He was the second child. Until she was found her father kept her hidden. Her mother had been floated when she was 4 because she stole medicine. She was arrested and sent down to earth with the 100. She quickly met with her cousin Clarke Griffin and they soon find out there are a lot more dangers in the world then Bellamy Blake. Bellamy was sure on getting Haley's wrist band even if it meant killing her. But then they soon became more then enemies. Grounders were a problem until Haley met Lexa (the commander) No one else knew that Haley was a night blood. Clarke and Haley took note that it would be safer that they kept them being cousins a secret until Clarke slipped up and told everyone. That made Bellamy more interested in the girl in the walls
