I am at a conflict. Already 1/3 way into my story, I have two decisions to make. First off my main character has 2 names. Her birth name and her given/earth identity. I want the character to know that her name is not the name she is known for. How from here do I continue to use her given name or her birth name. This is being written in third person and the MC accepts that her given name doesn't seem to suit her.
