By "doesn't appear much" I mean that I've only plotted her to be in one (maybe two) chapters. But she is a huge part of his motivation, and she appears in his thoughts. I am not using many POVs in the book. . All the action of the story takes place away from this character. Honestly, I never even considered using her as a POV, although I suppose it would be interesting. The problem is that I think using her POV would force me to create an unnecessary subplot.
