Justin believes that they can wait until morning for a worker to let them out, but quickly realizes otherwise when he remembers that exposure to sunlight will incinerate Juliet . Justin ultimately decides that Juliet needs to look in the mummy's eyes and become his slave in order to leave so she will not be destroyed, though he promises to hunt down the mummy and save Juliet one day . </P> <P> Meanwhile, Alex, in an attempt to sabotage Max's increasingly good behavior and gain a better chance at winning the wizard competition, has Harper separate Conscience from Max, and Max's behavior becomes increasingly horrific; however, she quickly rushes to fix the problem when Jerry informs her that Conscience will become his own person if he is separated from Max for too long . After reuniting Max and his conscience, Alex discovers Justin's plight and rushes to save him, but arrives too late to save Juliet from the mummy . </P> <P> Special guest star: Moisés Arias as Conscience </P> <Tr> <Th> 57 </Th> <Td> 6 </Td> <Td> "Doll House" </Td> <Td> Jean Sagal </Td> <Td> Vince Cheung & Ben Montanio </Td> <Td> November 20, 2009 (2009 - 11 - 20) </Td> <Td> 305 </Td> <Td> 4.1 </Td> </Tr>
