Jack Turner

Jack Turner (age: 20s) is a CIA field agent working at the North Dakota Black Site under Claire Madison.

Personality
Jack is stoic and fixated on physical fitness. Philosophically, he ascribes to a folk (i.e. not scientifically grounded) understanding of Darwinism that conceives of all of life as a struggle for dominance. He is not known to have moral scruples and views all physically weaker men, including his coworker Johnny Cameron, with contempt. Jack is liked by none of his immediate coworkers other than Claire Madison.

Biography
In a conversation with Claire, Jack explains that he was bullied as a child. He hated the bullies until he had what he describes as a "revelation" in high school biology class that it is natural that the strong dominate the weak. After high school, he dedicated himself to becoming mentally and physically strong in order to "actualize his potential." After college, he once returned to his hometown to ambush and assault one of the people who had bullied him, but decided against it, stating that the catharsis of that moment might diminish his drive and prevent him from achieving his full potential.

Relationship with Claire Madison
Despite the ban on relationships between superior officers and subordinates, Claire will occasionally call up Jack late at night to arrange sexual liaisons. The relationship is purely physical, as Claire is annoyed by Jack's pseudo-philosophical rants and finds nothing appealing about Jack other than his body and effectiveness as a field officer. Jack is sometimes shown failing to pick up women, implying that Claire may be his only sexual partner.

Death
Near the end of season 4, Claire orders Jack to sabotage the Apex Device as a part of Operation Calico. Jack fails to disable the device and is killed by the same beam of purple energy that triggers the Maurisuvius rift.
