Jocelyn Stevens

Dr Jocelyn Stevens, once known as Thomas Stevens, was the director of the Global Chemicals oil refinery at Llanfairfach.

Stevens had been taken over by BOSS, and tried to stop the Third Doctor and UNIT from shutting down the refinery.

The Doctor used a Metebelis crystal to help Stevens regain control of his mind. Stevens then supposedly sacrificed himself by triggering an explosion which destroyed BOSS and the refinery. (TV: The Green Death) However, Stevens was not killed but in fact survived the disaster. He sometime after went on to become Director-General of the BBC.

Twenty years later, he was once again under the influence of the computer known as BOSS, he'd been under BOSS' influence ever since the Llanfairfach incident. Neither of the them were killed. (HOMEVID: Global Conspiracy?)
