One of the scariest things about this episode is that doctors are supposed to be the most respected and trustworthy people around. They must have all kinds of background medical records on their patients, who in turn trust that the MD will NOT go against the privacy code of conduct. Dr. Psychopath (what's his name again?) chose Zoe because she fit into his perfect human image, so I immagine that the creeper would have been studying her and doing background checks on her for some time to satisfy his own perverse need for power. Nice thought eh? As if this episode isn't freaky enough as it is.
