A hacker, programmer, a member of fsociety, and Elliot’s sister. She was kidnapped as a child, and abused by her mother (though she describes it as her mother was ‘mean’ to her and Elliot). Unlike her brother, Darlene is outwardly cynical and jaded. This does not make her completely emotionless, however. She genuinely cares for her brother and maintained a healthy relationship with Cisco until his untimely assassination. She is also a skilled hacker in her own right, and remains loyal to her brother and fsociety even after being recruited as an informant for the FBI.
She may or may not be bisexual. She’s shown to have had relationships with men, and when she slept with Dom, it was as part of a Honey Pot trap.
