Dr Nasreen Chaudhry and Tony were drilling in Cwmtaff, aiming to dig further than anyone ever had before. After the Eleventh Doctor arrived in 2020, it became apparent something was wrong. It was soon discovered the Silurians were digging up to the surface. As they were preparing for an attack, Tony kissed Nasreen, expressing a previously unstated affection. He saved his daughter from an attack from a Silurian named Alaya, but was injured himself by a poison dart from the Silurian's tongue, which left him with a web of green veins on his shoulder.
