Early on Roy Larsen (John Wesley Shipp) remarks to Licalsi (Amy Brenneman) talking about gambling, that he "lost all his flash money". Shipp played Barry Allan/The Flash in the 1990 series of that name. (He also went on to play Barry Allen's father and another version of the Flash, Jay Garrick, in the Arrowverse series.) Shipp's delivery indicates that this was probably consciously put in by the writers as a reference.
The episode's title is a reference of the Rolling Stones song "Jumpin' Jack Flash"
