<okay I know this is not in the show but I want to put my own twists, for example the flame 2.0, icekeepas etc.> Y/N Stone is a girl who has different blood and knows a different language but she doesn't know what the language is called. Her blood is blue and very rare. Not very much people have this blood. The Council didn't like her roming around the Ark. So, when they found out she had blue blood they locked her up and made sure no one knows about this. Of anybody knows abouts Y/N's blood hey get floated. Y/N has been locked up for years. But, one day she got chucked into a dropship and sent down to earth. What will happen to Y/N if the grounders found out she had blue blood.
