Continuity mistake: When Arissa is first interviewed in Odo's office, she displays a 'data port' that is embedded below and behind her left ear in her upper neck. Her hair is styled to make it visible, and the port seems to be there for the entire scene, tho almost completely obscured at times. The second time she's in Odo's office, her hair style is the same, making it very obvious the port has now vanished, and it's gone the entire scene. For the third visit to Odo's office, the port appears and disappears at random. Apparently this scene was comprised of shots from the two separate shoots that made up the first two office scenes.
