-- from SB Sarah:
Seriously. Can we stop with the flicker of fear, the fleeting hint of desire, the flash of rage? COME ON. Couldn’t a hero have tension between his eyebrows, a wrinkle near his eyes that indicated rage that smooths out before she gets a good look? Something other than an emotion floating in his eyeballs that she gets a glimpse of?
Oh, see, I really have nothing to add to this. Nothing.
-- except to say: unless you have an x-ray machine and/or are a doctor of psychology and fairly certain about your patient, the human body can only tell the reader what anyone would be able to see from the outside. Unless you've got an ophthalmology license, there's just not too much you can read in someone's eyes. And if they're flashing? Just think POLTERGEIST. Or, very angry djinn. And run.
