Olivier Duval, born Kevin, was a mysterious man who appeared to have been a part of the group that created the LEDA clones.
He is first introduced in "Conditions of Existence", when he visits Paul at his office to ask about Beth's condition, a day after their most recent examination of "her". He likes to remind Paul that his job as Monitor is to simply observe and to not interfer unless "it's critical."
He is transgenic, as he as a small pink tail that Helena cuts off.
