Hex (Doctor Who)

Thomas Hector Schofield, nicknamed Hex, is a fictional character played by Philip Olivier in a series of audio plays produced by Big Finish Productions based on the long-running British science fiction television series Doctor Who. A staff nurse working for St. Gart's Hospital in London in the year 2021, he was a companion of the Seventh Doctor. The canonicity of the audio dramas, like other Doctor Who spin-off media, is unclear.

Hex first appeared in the play The Harvest (2004), where he met the Doctor and Ace while the two were investigating signs of alien activity at St. Gart's. Ace was going by her real name of McShane and working in Human Resources, striking up a conversation with Hex to gain information on the mysterious C-programme. When Hex gave Ace a ride to her "lodgings" in Shoreditch, he spied her going into a police box at Totter's Lane. Hammering on the door and demanding to know what was going on, Ace let him inside the TARDIS, and Hex's world was transformed forever.

Hex aided the Doctor and Ace in their investigations at St. Gart's, uncovering the latest invasion scheme of the Cybermen and helping the two time travellers defeat their old foes. At the adventure's conclusion, Hex asked if he could accompany them in their travels. The Doctor did not seem surprised that he should ask, and accepted him as his newest companion.

Schofield, who hated his real name and preferred to go by Hex, was incredulous of the strange things he saw, but was able to adjust rapidly and accept the evidence of his eyes. As a result, although he admitted that he did not know what he was getting into when he asked to join the Doctor, both the Doctor and Ace seemed confident that he would be able to cope.

At this time, the circumstances of his parting from the Doctor have not been revealed.
