My character is a fisherman who owns a fishmarket. I need to give him a personality trait, or something else, to make him more interesting especially in a dangerous environment. For instance, I was reading a James Rollins novel the other day, and one of his characters suffers from seizures. This is a very interesting characteristic because it can happen at any time and can move the story forward or create suspense. I was thinking something similar for the fisherman, like that he can't swim (although this is unlikely) or that he has a phobia of a certain common animal etc. Any ideas? Thanks so much!
