Will Graham states that Georgia Madchen is unable to "see faces." This is an actual cognitive disorder: prosopagnosia, or "face-blindness," is the inability to recognize people by their faces. People with prosopagnosia often need to rely on things like context, voices, and clothing to recognize people they've met before.
Ellen Muth guest stars in this episode as a character named Georgia Madchen who thinks she's dead. She previously played a character named Georgia (George) Lass who actually was dead in Dead Like Me (2003). Bryan Fuller created both shows.
The publicity photo for this episode (as seen on IMDB and Hulu) shows Hannibal wearing his clear plastic coverall, and with a strange collection of black dots on his face. Those dots are never seen in the episode; they were drawn on the actor's face to facilitate the later addition of a face-blurring effect, simulating another character's inability to recognize faces.

About Georgia Lass/Madchen: 'Mädchen' is German for 'girl,' just as 'lass' is Scottish for 'girl.'
