Ira Blair was a self-aware male clone from project Castor. He was raised separately from his brothers by Susan Duncan and is portrayed by Ari Millen.



Not much is known about Ira's history.  However, we do know that some time after the fire that was believed to have killed Susan and Ethan Duncan , Susan adopted the then four year old Ira to raise as her own.  Ira works closely with Susan in her research to find treatments for both sets of clones, including Charlotte Bowles.
