Darlene is a malware coder whose skills are fundamental to fsociety's master plan. Though biting and jaded, she becomes Elliot's confidante. He relies on her resilience and creativity for quick problem solving and fast hacks. She is an excellent lock picker, a crass jokester and a jobless transient. She obtains money from hacking ATMs.
Like most fsociety members, she is reluctant to reveal too many details of her history, and she is paranoid about communication. However, Darlene's loyalty trumps all, and in the end, her big heart overrides her sharp tongue.
