Ok, I haven't seen anybody mention this but I don't believe aria is an author. I think she's the person that goes with the authors to help them out events, maybe she's a junior junior editor.<br /><br /> If you notice at the beginning of the episode she's in front of the camera until she says all good, then gets up and a man takes her place. My assumption was she was there for the light test and once they were ready the author stepped in.
