I’m not talking about story goals here. This is something deeper, more at the core of his being. James Scott Bell writes about this in his book Conflict & Suspense.
The hero may not even realize it’s present. It’s something he doesn’t have but yearns for. Bell defines yearning as a desire for something without which the person feels incomplete. And he may not even be aware the yearning is there until a story event triggers a response based more on the yearning than on the event itself. This could lead to behavior, an overreaction or under reaction, that makes little sense to the other characters and to the hero himself.
This yearning is in your hero’s history, perhaps something from his childhood. Whatever it is, it predates the story. When he comes into the story, he’s already carrying trouble in the form of this unfulfilled yearning. This gives you all kinds of possibilities for unpredictable actions by the hero as the unspoken yearning influences his behavior and relationships with others.
For example, say your hero yearns for a strong father figure because his father left the family when the hero was a boy. In your novel, he might have a hard time seeing the antagonist as the villain because he develops a strong emotional attachment to the man early on. As the villain is slowly revealed, the hero rebels against what he sees and may even attempt to shield the bad guy, defend him, rationalize his behavior. Or he may feel betrayed which can send him down another path in the story
Next time you feel stuck with your hero, dig deeper into his history. See what unexpressed yearning he’s hiding from himself—and from you.Now the tension and potential for a tragic outcome is heightened as the hero’s yearning, and resulting idolization, of the villain conflicts with the reality of who and what the villain really is.
