Fan Casting Ian Chase in Batman: Arkham Origins

During a Halloween Party at Wayne Manor, Ian Chase ended up causing a disturbance (presumably by harassing Clarissa Rodriguez, based on a comment made by Alfred), which forced Bruce Wayne to throw him out. Two months later, on Christmas Eve, Chase, by that time, a gang member to The Joker (who had taken over Black Mask's Gang) went to Crime Alley and proceeded to murder both Rodriguez and her fiancée, Horace Riley, by shooting her in the heart, and shot him in the lung, respectively, coincidentally at the same spot where Bruce's Parents had been murdered during a mugging during Bruce's childhood.
