I've noticed in novels that I've read that characters that will not be recurring generally aren't named. This tends to lead to some predictability, where if a chance encounter with a new character happens to reveal that character's name, then you can pretty much rest assured that that character will pop up later on. Is this a general rule? Is this something that is expected to be done? I have an idea for the start of my novel, where I introduce a non-recurring character so that he can help portray my MC. I want the reader to view my MC with a sense of awe and... newness. Not sure if I conveyed my meaning across very well but I hope someone can shed some light on the issue.
