I imagine if Camille was berating Amber on the stand and suddenly everyone in the court disappeared, Amber would leap over her chair and grab Camille by the hair. Camille would be rag dolled for a few seconds before being dragged by her hair to the floor. Amber would then sit on top of her unleashing hellfire until Camille begged for her to stop. Only I don't think she'd stop until Camille was out cold. The way she looks at Camille is murderous.
In a cage with no rules I believe Amber would win by TKO in under a minute.
