When Harmony Wolfe got arrested, no one knew about the plan to send the 100 down to Earth. It had barely been thought of, and was only a last resort. When Abby Griffin comes to tell her, she puts on a scared front, but in reality, she's ecstatic. It's a way out of her cell, where she's had minimal contact with people for almost two years. She sees it as a chance to start again, to be with her friends and what family is with her, to have a life outside the metal walls that are slowly making her go insane. But when they reach the ground, she's thrown into a world that she's not expecting. That's not to say she's unprepared for it, in fact, quite the opposite, she's totally ready for it. What she's unprepared for is Bellamy Blake, who is way too overprotective of Octavia, and might, just might, be paying Harmony a just little more attention than she's used to.
At the time Melody Wolfe got arrested, she was beyond ticked. All she knew was that she hadn't seen her cousin, her best girlfriend, in over a year, and suddenly, Harmony's two best friends, who weren't locked up, Jasper and Monty, decide to tell her that Harmony was arrested. When they go missing, and, soon afterwards, Melody's best friend, Anthony Kane, does, as well, Melody breaks down, getting herself arrested six months later. When they get put on the dropship, Melody has no idea what is going on, and when they land, unlike Harmony, Melody is completely unprepared, in pretty much every single way, for life on Earth. Especially when she starts developing feelings for one of Harmony's best friends, a certain Jasper Jordan, who only has eyes for Octavia Blake.
