When Peters made his American Horror Story debut, he portrayed the troublesome teenager, Tate Langdon. He was originally thought to be a distraught patient of Ben Harmon and the love interest of Violet Harmon. In reality, he was a ghost who was trapped inside the Murder House. It was later revealed Tate carried out a school shooting years prior, something his mother, Constance, tried to keep hidden from the Harmons. Violet rejected Tate after learning the truth. Over the course of the season, Tate killed multiple people as the Rubber Man and raped Vivien Harmon, Ben's wife and Violet's mother. The birth led to Vivien's death and the child went on to become the Antichrist.
