T (short for Tony Tsetsang) was the son of Anthony Ceccoli and Priya Tsetsang, born several years prior to 2020 but after 2010. As of 2020, T was living in Safe Haven with his mother, and Adelle DeWitt along with Echo and Paul Ballard, and had not been able to get to know his father very well.
T was born between the years of 2010 and 2020 to Anthony Ceccoli and Priya Tsetsang, and had spent at least some of his childhood growing up into a post-thought-ocalyptic world. (S2: "Epitaph Two: Return") As of 2020, T had not gotten to know his father very well, nor had he ever tried strawberries, having to be assured by his mother, Priya, that they were safe. (S2: "Epitaph Two: Return") T traveled with the others to the L.A. Dollhouse and managed to get inside when the Butchers attacked, later staying inside the facility with his mother, father, Echo, Mag and Kilo when it was sealed for a year to protect the former actives from the effects of Topher Brink's reversal bomb. (S2: "Epitaph Two: Return")
- It's not made explicitly clear when the thought-ocalypse occurred, there are hints that it had happened recently as of 2019 as there are hints of it taking place shortly after the attack on Rossum as seen in "The Hollow Men"
