Biography
Along with Dr. Nasreen Chaudhry, Tony was drilling in Cwmtaff and aiming to dig further than anyone had before. After the Eleventh Doctor arrived, it became apparent something was wrong, and it was soon discovered that the Silurians were digging upwards to the surface. As they were preparing for an attack, he kissed Nasreen, apparently expressing a previously unstated affection. He saved his daughter from a Silurian attack, but as a result, was injured himself by a poison dart from the Silurian's tongue which left him with a green system of veins on his shoulder.

Tony later discovered that Ambrose had accidentally killed Alaya. He was present when Alaya's sister, Restac, contacted the group, wanting to exchange hostages. Before they went down, Tony was convinced by Ambrose to set the drill to reactivate a short while after, so that it would destroy the Silurian civilisation. When the group came to the city, Tony brought forth Alaya's body. Restac, distraught, ordered her soldiers to kill them all. With the help of the Doctor and Eldane, a Silurian elder, the group managed to barricade themselves in the laboratory, where Eldane revealed that Alaya's poison was causing him to mutate, and that his only hope for a cure was their decontamination equipment. With Restac's warriors surrounding them, Eldane had no choice but to activate a fumigation system and re-enter hibernation. Tony elected to join the Silurians in hibernation, having his condition cured during that time. Joined by Nasreen, he bid his family a fond farewell. (DW: Cold Blood)
