Jtomassetti In British English from the mid 1700s to the 1920 the adjective "bloody" was considered to be strongly obscene like the F-word is now. However, more recently the word "bloody" has become a comparatively mild expletive or intensifier. So around the 1800s when this book is set, it was a very salty word that might be common among sailors. But also Jack's clothes end up covered in blood at certain points in the book.
Lisa Angle Not really a spoiler...a lucky shot splatters her with blood and earns her the respect of her shipmates.
