It is said of Tate Langdon that he needs to be beautiful, angelic, and terrifying. As the father of the Antichrist, Tate is a sort of Lucifer himself, a fallen angel whose seed will bring about the end of the world. At first when audiences met Tate, they saw a troubled young man in his high school years seeking counseling from a skilled professional. It does not take long for viewers to recognize that all is not as it seems with Tate.
