After several failed attempts to save her daughter's life, Helena eventually realizes she is unable to change events from the past, and after murdering the men who killed her daughter, she continues to behave recklessly until she eventually inadvertently causes the death of a fellow agent. This event shocks her to the realization that she has become a danger, and she chooses to be bronzed to prevent any further damage. Bronzing is a form of punishment the Warehouse utilizes after conventional imprisonment has failed or is not an option. The subject is cast in bronze in a special machine and thereafter remains conscious, but in a state that resembles cryogenic sleep where the aging process is stopped. She remains bronzed until set free by Leena on the order of James MacPherson in the season finale of season 1.
