Divatox and Dimitria sisters?

As everyone knows, PR Turbo got pretty boring and as a result, I stopped watching. Before I quit watching, I was under the impression that Divatox and Dimitria were sisters or something (possibly played by the same person). I just found it weird that Divatox wore a mask to cover her eyes and Dimitria wore a cloth to cover her nose and mouth. And to me their voices sounded similar. Because I stopped watching PRT I never had this question answered. Were they infact sisters or do you think is was one of those storylines that was just forgotten about or is this all in my imagination?
