Della

From Tardis Wiki, the free Doctor Who reference

Della and Stott were assistants to Tryst on his expedition to collect and catalogue flora and fauna from many planets in the galaxy. She was on board the Empress when it collided with the Hecate on emerging from hyperspace above Azure. When she found out that Tryst was smuggling vraxoin, Dymond shot and wounded her, but she later recovered. (TV: Nightmare of Eden)
