I just watched Dollhouse Season 2 episode 11

My mind is blown.  I mean, seriously blown.  I'm having a BSOD moment.  I'm probably typing this just to stay sane.  I'm in shock.  Of all plot twists I've ever seen, this one is the one that's thrown me for the biggest loop.  I'm completely baffled.  This is absolutely crazy.  My mind has been blown.  My mind has been blown.  My Mind Has Been Blown.  MI MIND has been blown.  my mind has been blown.
