The seventeen-year-old Sociopathic Patient of Ben. Tate is in a relationship with Shilo Harmon. Tate can be violent, creepy, charismatic, and finds humor in making Ben mad. It is clear that he's in love with Shilo and won't let anything keep them apart. He's also possessive, protective, compassionate, and loving. He threatens to kill his own mother when she tries to poison Shilo (he was informed of this by Moira, of course). That is the first time it becomes apparent that though she loves him, Constance is also afraid of him. Tate feels too strongly and it is due to this fact that he doesn't react rationally to certain things. Though not visibally imposing, something about Tate terrifies the hell out of people. Maybe it's his black eyes. Either way, a sure fire way to piss off Tate: Mess with Shilo and you'll find yourself on the very top of his shitlist. Ben would know. He already has a spot right next to Constance. Tate hates his mother, though it is unclear why. Tate's violent behavior towards others that try to push up on what he considers his and possessiveness with Shilo becomes apparent when he knocks Ben to the floor and says in a dark, almost inhuman voice: "I don't want to hurt you Dr. Harmon because though she claims to hate you, your death would bother Shilo. But let whatever shit god I still believe in be witness to this: If you try to take Shilo away from me, I will kill you."
