Since I don't know the particular novel, it's difficult to say exactly who the man of medan is. It could be a protagonist, an antagonist, or a minor character. Maybe he has certain unique traits or a significant role within the story of that novel.
It's a horror story set on a haunted ship. A group of characters find themselves trapped in terrifying situations with mysterious and deadly events unfolding.
The theme of self - discovery might also be present. Loker and Torres, like all characters, have their own personalities and flaws. Fan fictions could explore how they come to understand themselves better through their experiences in the story. Maybe Torres discovers a new aspect of her strength while working on a case with Loker, or Loker learns to overcome some of his insecurities in the presence of Torres.
