Black Dahlia is an expert in infiltration. While most covert operators received training in the military or various alphabet agencies, Black Dahlia is admittedly self-trained.
She spent the first 6 months of the end of the world as we know it as a captive. The following year of the zombie apocalypse, she survived in the shadows. After escaping her captors, she vowed to never be caught again, and she became a whisper in the wind, the shadow you thought you saw moving from the corner of your eye.
