Rose Callaway

Rose Callaway was a recurring character in the second and third seasons. Rose is the daughter of President Lucien Callaway, but was never taken seriously by him. She worked as a member of the Mount Weather Guard, but rarely left the mountain. Her knowledge of the mountain and compassion toward the delinquents kept them alive and eventually allowing them to escape. Rose was one of the members of Mount Weather that received a complete bone marrow treatment, making her immune to radiation poisoning. Despite this, Rose was unaware of the treatment source and was a member of the Resistance Against Harvest Project.

Origin
Born to the president of Mount Weather, Rose inherited a life time of high expectations. Rose always thought she would follow her father's footsteps and become the president one day. However, he never viewed her to be enough because of the fact that she was a woman. Because of this she shifted her goals and wanted to join the Mount Weather Guard in order to ensure her security in the future.

Rose eventually achieved her goal of becoming a guard, but it wasn't easy following that. On a mission to collect "Earth samples" with Peter Tremblay, Rose was attacked. She was significantly injured, nearly bleeding out and suffering from radiation poisoning. Because of this, Rose received the complete bone marrow treatment but was unaware of the source... Scout Farrow. Following this, Rose was benched from some of her guard duties and was kept inside the mountain, isolated from significant guard happenings.
