my pet peeve of the day

It drives me absolutely crazy when in ST:AOS fic the older, time-traveling Spock is called "Spock Prime" within the story text, assuming the story is told from a POV character withing the fictional universe rather than some jokey outside parody narrator or omniscient meta fiction narrator. It's fine for a pairing label, but please, please find some other way to distinguish the character from the younger Spock in the text. I am usually not that picky about narrative voice, but this just throws me out of the story in a way from which I can't recover. It's one of the few things that will just make me stop reading immediately in this fandom.
