| || Tate is a live human
By default, any human-seeming character we see where we have not seen their deaths may, in fact, be human. Actual bona-fide living humans are the minority on this show.
| || Tate is a ghost
This is the majority opinion. Tate's ability to interact with solid objects is also seen in Moira, and we know she's a ghost. In "Home Invasion", he was able to teleport throughout the house and walk through walls (though he is the only ghost we've seen to do this). Additionally, the ghosts of the students he killed were said to have been in their thirties, had they remained alive. Tate, on the other hand, remains a teen. This has been confirmed in "Piggy Piggy" by Constance's medium friend. She refers to Tate as one who "doesn't even know he's dead" and urges Violet that she must help him "move on."
| || Tate is a medium
By definition, a living human who can see ghosts. Given the frequency with which this occurs with random house visitors, this ability seems to not be needed to interact and see the spirits within the house.
| || Tate is Constance's son
| ||Tate murdered his other sibling, a sister, as a child|
| || Tate is the Infantata
As it is stated in "Halloween: Part 1", the Infantata is the son of
| || Tate is a projection of the House
Tate seems to be connected, acquainted, or knowing of all the entities, ghosts, and other beings that live in the house. Violet's initial attraction to the house, despite its nature, could also be evident in her interest in Tate. Tate's feelings for Violet could be due to her (presumed) connection to the house. Additionally, Tate often proclaims his "innocence" in all of the murders in the house since the Harmons moved in, yet he has been involved in all but one. Tate may very well be a personification of all the malevolent energy (for lack of a better word) in the house.
| || Tate is Rubber Man
It was revealed in episode eight that Tate is indeed the Rubber Man.
| || Tate has a twin
| || Ben and Tate are siblings.
Ben could be Tate's brother, and Constance's fourth child. He may have been institutionalized in his teen or childhood years for doing something bad. It's also possible that Troy and Bryan are young Tate and Ben (note the same first letters of the names). Also, Troy and Bryan are always seen wearing striped shirts and jeans and images of someone who looks like Tate wearing a striped shirt and jeans appears during one of Tate's therapy session with Ben.
disposition2=proven|option2=Tate has an alter ego. In the pilot episode, Tate describes his "fantasies" to Ben, which include him strolling through a busy highschool hallway dressed in civil war attire and skull makeup with his hair slicked back. In actuality, as it is shown in "Piggy Piggy", Tate wore the jacket to the school shooting but kept his hair and face the way it usually is. It could be presumed that Tate's fantasy of his school shooting could be his imagining of how he sees himself/ or an effect from the crystal meth he is seen snorting that morning. Another part that shows this is later in the pilot when Tate writes "Taint" on Violet's chalkboard in her room, in no relation to anything currently happening in the plot. It is likely, him being a psychopath, that Tate created an alter ego for himself to cope with the violent deeds he seems to remorse and grieve about over time. |disposition4 = proven
