Constant
From Tardis Wiki, the free Doctor Who reference
Sisterman Constant was a medical professional on Mondas. She recommended people to be called up to the surface. When Zheng took command after the power went down, he placed her on the conversion line and she underwent cyber-conversion. She was not destroyed and continued working for Doctorman Allan, who was ultimately killed by Zheng, whom she thought destroyed. (AUDIO: Spare Parts)
