Spy is a handsome and well-maintained Frenchman in his 40s who appears deceptively youthful. He has a difficult and demanding personality, holding both himself and others to high standards. Prone to intense emotions, he can be hot in love and in hate, and is described as being terribly jealous. He speaks English well, but will often use French phrases, especially when he's agitated or angry. He is observant and can be silent and calculating.
