SPOILERS REVIEW
My thoughts:
I believe Zamra is not putting herself forward for catfighting because she wants to compete and win, I suspect her real reason is that she is a female submissive, who enjoys getting rough handling from another woman, while putting up a token amount of effort. It was noticable that Bella was not attacking her 100%, as there was no need to, it was not an equal struggle.
Bella I would want to see again, with someone who can test her properly with full effort slapping and hairpulls, Nikki would be best for this.
