|Portrayed By||Kathleen Munroe|
|First Seen||Original Sin|
|Also Known As||
|Family||Lee Rosen (Father)|
|Alpha Type||Empathetic Contagion|
Danielle lived with her father for most of her childhood, with Dr. Rosen realizing the nature of her Alpha ability at age nine. She characterizes those years as possibly abusive, as her father manipulated her into using her powers on her mother, who was considering leaving Lee. Her empathic powers also allow negative emotions from nearby people in, keeping Danielle in a fairly constant state of pain. Running away at an early age, Danielle coped with her Alpha power by self-medicating, with drugs from opiates to anti-convulsives.
In Original Sin, Danielle is being chased by Isaac along with a 34 year-old man named Will who lived on the streets with her. After watching the man die at Isaac's hand, she escapes to a nearby hotel, where her father finds her. After Cameron shoots Isaac dead, she's taken back to DCIS office. Setting aside her animosity towards her father, she gives them an encrypted message meant for Red Flag members.
