Tad first appeared in 1970 in the playroom wearing his 1840s clothing to Hallie, who thought he was David, until she left the room and saw David in the hallway wearing his modern clothes (1079). Slowly, the spirit of Tad began to take control of David, much like the spirit of Carrie did with Hallie. Ultimately, Tad permanently possessed David one night at Rose Cottage, which was all part of Gerard Stiles' plan to take over Collinwood. Tad was killed by Gerard, along with Carrie and Daphne Harridge who had also come back to life, in the playroom when the Destruction of Collinwood took place.
