Sydney seeing just how robotic and mindless Keith has become as a result of re-education.
We are finally going to find out what exactly happens in a re-education centre. If you didn't think the Alchemist superiors were psychotic before, you will now.
To make things worse, they are keeping Sydney drugged and in a pitch black room, so neither Adrian nor Ms Terwiliger can find her. Kind of makes you wonder if they have actually been monitoring Sydney all this time and gathering as much info on what she's been doing all this time in order to stop her from being found, or if the setting for the re-education is just how the normally do things.
