Ellie butts heads with Brass frequently due to her profession, and the fact that she is willing to go "bare back" (condomless) if the price is right. (Hollywood Brass)
Despite this, she did visit Jim at the hospital after his shooting.
Ellie's biological father is former New Jersey Vice cop Mike O'Toole, who was having an affair with Brass' wife. (Hollywood Brass)
Ellie doesn't know that Jim is actually not her biological father. 
Ellie was a prostitute in Los Angeles (where she was known as Jersey). Her best friend went missing and the LA police refused to look into it, so she called Brass and asked him to make a phone call.
He went to LA to investigate her missing friend; it turned out she had been murdered.
Ellie came to Las Vegas to work as an "escort".
While Brass was in surgery, Grissom called Ellie to come to the hospital.
While her father was in the hospital in critical condition, Ellie seemed more concerned with the pension than her father's likelihood of survival. (Way to Go)
Ellie is the main subject in Strip Maul between Jim and a girl called Chastity who knew Ellie and bought her mother's engagement ring for $200. Later, Chastity tells him to go look for Ellie.
Ellie is discovered to be both the girlfriend and partner of the serial killer after shooting him to death. After killing him, she proceeds to shoot Morgan in the back. Later, she kills her mother.
Ellie has been behind the murders in "Skin in the Game" all along and has been held in custody.
Relationship with Jim BrassEdit
Despite Ellie's rebellious behavior, Brass still loves her deeply and keeps a picture of her as a child on his desk in his office.
