I am writing a book about a woman who has been in abusive relationships all her life, so as you can guess, her logic isn't always the most sound. I want this logic to come across to the reader, but I've heard that when you do that in third-person limited, you can't have the actual narrator explain things using this logic. Like you can't write something like "She had probably just been ungrateful," in response to her getting punched by her abusive husband for no good reason. Instead, you have to write it as, for example, a thought she has. "I must have been ungrateful, she thought." I guess this has something to do with the whole "untrustworthy narrator" that I've heard about, which is something I've heard you are only supposed to do in first-person. So, can my third-person narrator not say things that, in one way or another, isn't true? Can't he lie, even if it reflects the thoughts and personality of the character that the perspective is coming from?
