A question for you pantsers. I've had pantsers get angry when I said that writers either plan their stories before they write them or afterwards (in prodigious amounts of rewrites). They insisted that I was wrong and that they didn't need any but the smallest rewrites. So, what do you do when you realize that you left a plot hole fifty or a hundred pages ago? I ask because I'm taking a break from my main WIP to create a simple middle grade novel which I'm trying hard to keep from planning, but I found an error in the first thousand words. The story starts with a twelve-year-old boy regaining consciousness in a hospital emergency room. He has near total amnesia of everything prior to the emergency room. His anatomy isn't really human (though he appears human on the surface). What I overlooked is that he would need an ally in the hospital who could help hide his medical records. I'm interested in the process you pantsers go through to fix plot holes.
