Dorabella

Dorabella was a girl that Edwin Bracewell had memories of loving. The android Bracewell concentrated on her name to break free of his Dalek programming.

He said she had "such a smile", and that her eyes were blue, "so blue", "almost violet, like the last touch of sunset on the edge of the world". Before he left, the Eleventh Doctor told Bracewell to "on no account go looking for her", but hinted that he should. (TV: Victory of the Daleks)
