So in my WIP I have a limited third person POV. Most of the time I am in Valorie's head but for one chapter I switch to her sisters POV. Her sister always calls her Val. With the only exception being if they were like in court and a judge asked her Valorie's full name. lol. So since she always calls her Val. Should the narrative then call her Val when I am in her head with the third person POV?
