Sienna Gray grew up on the infamous space station-The Ark-with her best friend Bellamy Blake. Sienna had a rough life with a father who was unknown and a mother who was hardly around. It's not that Sienna thought her life was rough, she loved it actually, it was that her mother wasn't around often. Her mother was always working; she was a doctor/surgeon. Whenever her mom was home, she would only talk about herself. Sienna was left to fin for herself, but thankfully her new founded friend helped her along the way. That was eighteen years ago, both of them being the age of five. Bellamy Blake was a reckless and kind of a wild child. Sienna was quite the opposite. She was always the adult of the situation-even when they were younger-and would take charge. Her life taught her to be that way, because she was alone. Little did the know, her best friend from across the hall would end up saving and changing her life forever. "Do you want to do something really stupid and reckless with me?" "Do I have a choice?" "No." "I figured." Sienna is played by Amber Heard
