Tasambeker Brown
Tasambeker was an employee at Tranquil Repose on the planet Necros. She was a third year student of Jobel's and worked under him.
She had great feelings for Jobel even though he insulted and humiliated her. When Davros took over Tranquil Repose as "The Great Healer", he turned it into a breeding ground for Daleks and would use hidden cameras to observe the funeral home, observing Jobel and Tasambeker.
He offered her to work directly for him and they used the cameras to see Jobel conspiring against Davros with Takis and Lilt. He wanted Tasambeker to serve him with her total being and he would allow her to become a Dalek: it was an offer she couldn't refuse. To show him her total obiedience, she had to kill Jobel.
She confronted Jobel and offered to help him escape Tranquil Repose, claiming that Davros lied and that he didn't care about Tranquil Repose. He wouldn't hear her at all and she killed him by stabbing him with a syringe.
Tasambeker went off into the hall, crying about what she had done when two imperial Daleks entered the hall and exterminated her. (DW: Revelation of the Daleks)
