Ira is the only Castor clone not raised in Virginia Coady’s rigid pseudo-military regimen, Ira is more "West End" to their "Westpoint.” Taken by Susan Duncan as a young boy, Ira was raised in the science of Neolution and later became Susan’s lover. After Susan’s falling out with Rachel, Ira is uncertain as to where his loyalties should lie. Fully aware that as a Castor his life span is currently limited, Ira’s continued trust in Susan, or Neolution entirely, may very well be misplaced.
