First let me explain a little. I have created a male protagonist through which most of the story I'm writing is seen. He is a very serious character and rather quiet. Think of Toshirō Mifune in the film Yojimbo, or Clint Eastwood in The Dollars series by Sergio Leone. Another really serious character I can think of is Stephen Dedalus in Joyce's works but my character isn't quite so dark. He's just somewhat reserved and very dedicated to his view on life which is not a such a terrible one. He wants to see civil order in the world I've created. He meets a female character in his travels who he soon finds out he knew as a child. However, they only briefly came into contact as children. She could equally be seen as a protagonist in her own right, especially in the second part of the tale (book II) where they are briefly separated. The thing I've noticed is that the main protagonist seems a lot less strict to his principles and a lot more free when in her presence. He seems a lot more amiable to me anyways. At times his serious nature seems to bring about a comical relationship between the two as she is a lot softer and kinder. I think she brings out the best in him as he is defeated each time he is around her. He's no longer the stone cold killer. When they first meet she attempts to be kind to him like she is with almost everyone and he is a complete arse, and I think he sees this because of her. She in turn is very passive at first but in book II while traveling on her own for the first time becomes a little more hardy. There is a lot of balancing going on here and it seems good, after they first meet. The problem is that there is a great deal that takes place before the protagonist meets this girl and I feel that he is at times too serious. I feel like he doesn't need to be quite so serious. I feel as though serious might come to mean boring. The reader will never get to the good interactions. I feel like there is a workaround. Like Dune, I have a lot of characters and the protagonist is not in every scene but he is in the majority of scenes in the book.
