So... How bad is it that I have a couple in my book that are slightly similar to Madame Vastra and Jenny from Doctor Who? I mean... It's to the point where one side of the relationship is human and the other is a mermaid, who happens to also be a queen, and mus wear a veil in public [which is due to her religion, but still]. I swear this was done by accident but can I still keep it? Or will I find a lawsuit by BBC on my desk?
