In most works of fiction, the protagonist will have an internal struggle with whether or not they should join the story. In many cases, your protagonist does not want to accept the situation you have created for him, and rebels emotionally against it. This sense of the unwilling, or unlikely hero pervades many of the best novels. For example, Bilbo may have agreed to go on the journey with Gandalf and the dwarves, but he never really accepts his new role until after his experience with Gollum and the goblins.
