Elliot Northover was the child of Mo and Ambrose Northover, and grandson of Tony Mack.
Biography
Elliot lived in the Welsh valley of Cwmtaff with his mother, father and grandfather. Elliot was dyslexic, and therefore he preferred to listen to audio books rather than having to read them. He had a great interest in Sherlock Holmes.
When a drilling project in Cwmtaff awoke a civilisation of Silurians, he was chased and kidnapped by Alaya. (DW: The Hungry Earth)
Elliot was kept in a stasis chamber by the Silurian scientist Malohkeh, where his ageing was considerably slowed so the Silurians could study how humans grew. Eldane, the Silurian leader, gave Mo and the Doctor permission to take him out. He escaped the Silurian city along with his mother, father, the Eleventh Doctor and Amy, with the promise that the planet would be shared with the Silurians in a millenium and that he was to spread the word.
