What if 'Jack' was instead a 'Jane'? Yes, true forbidden love. A lesbian affair
A tomboy who travels the world, passing as a boy when needed, but actually a 32 year old woman, with a thing for redheads.
She saves Rose from jumping off the ship. Everyone thinks that "Jack" is a boy, no older than 16, but she turns up to the thank you dinner in a beautiful dress and her boyish hair styled back.
Rose can't take her eyes off of her. How can she look hot both as a boy and a woman?
Of course, she goes back to her tomboy look, which Rose is also crazy about, never before knowing that a woman could convey masculine energy and put moves on girls.
She draws her naked, does her in the luggage hull, and gets in trouble for it.
"Forget this lesbian affair, Rose! You are to marry me!" yells Cal.
"But I love her!" Rose protests.
"Do you really think you could have a good life with her? She's nothing but a vadabond!"
In this story, when "Jack" dies, she gets off the wood, sinking to the bottom with her.
Now that is true love.
