In the silence between whisper and shout

I had a dream last night about a Pirates of the Caribbean OC who was Jack Sparrow's daughter, but in a plausible way. Her mother was a prostitute whom Jack visited sometime in between At World's End and On Stranger Tides, so their daughter Rose (short for Rosamond) would be about the same age as Henry and Carina in the present. No one knows that Jack is her father, and even if she meets him, she'll probably never find out.
