I'm no one's bitch.Atom to Octavia

Atom was a minor character in the first season. He was portrayed by cast member Rhys Ward and debuted in "Earth Skills".

Atom was one of the Delinquents sent to Earth to see if it can support human life. Atom was a close advisor to Bellamy Blake and was a love interest for Octavia Blake. He was euthanized by Clarke Griffin after he was trapped in the acid fog and was found severely wounded.

Early Life

Not much is known about his life before coming to Earth. Because he was under 18, he could not be executed and was imprisoned instead. He was sent down with the rest of the prisoners to Earth to see if it was sustainable for life.

Throughout the Series

Atom and Octavia in the butterfly forest

In Earth Skills, Atom makes his first appearance as one of Bellamy's guys who are extremely loyal to him. When Bellamy decides to go look for Jasper Jordan with John Murphy accompanying him, Atom is requested to stay back at the camp and watch over things, specifically getting the task to watch over Octavia Blake and make sure she stays put. The day consists of Octavia consistently taunting him about always following orders and never doing what he wants to do. He locks her away in the ship with Monty Green for a little bit, before letting her out. He follows her to where the butterflies are and ends up kissing Octavia, finally not following orders anymore. They are later seen kissing again, only to have Bellamy catch them. The furious brother and his thugs Murphy and John Mbege tie him up to a tree and leave him alone in the dark.

Clarke kills Atom out of mercy when Bellamy can't do it

In Earth Kills, Atom searches with Jones for the two lost delinquents, Pascal and Trina with no luck. Atom later blows off Octavia when she tries to talk to him because Bellamy punished him when he first caught them kissing. While hunting with Bellamy and others, Atom trips and becomes trapped in an acid fog that blows through the forest and suffers badly; there are bumps all over his body from where the poison touched his skin and he is blinded by the fog. He begs Bellamy to kill him to end his suffering but Bellamy can't bring himself to do it. Instead, Clarke comforts and hums to him, as she kills him by stabbing him in the neck with a knife. Octavia is deeply hurt when she sees his body and Atom is later buried.

Personality

Atom was a loyal individual who followed Bellamy's commands. He also showed a more compassionate side with Octavia.

Physical Appearance

Atom was of average height and physically fit. He had short black hair and blue eyes.

Relationships

Main article: Octavia and Atom

Atom and Octavia's relationship first started on the rocks, but it began to improve as it progressed. While Atom eventually viewed her as a brat and as an assignment, Octavia began to develop feelings for him and eventually convinced him to let loose and the two kissed several times. The relationship is halted when Bellamy discovers them. Atom then ignores Octavia in fear of getting punished again. Octavia is incredibly upset at his death, suggesting she had strong feelings for him. 

Atom obeys commands from Bellamy, like a soldier and general. This eventually becomes strained when Atom is caught kissing Octavia, something Bellamy had ordered him not to do. This causes Bellamy to mistrust and punish him for the incident by hanging him from a tree for disobeying Bellamy. When Atom is dying from the Acid Fog, Bellamy is visibly upset and is unable to kill his friend. Clarke has to eventually euthanize Atom in order to end his pain.
