SV39
From Tardis Wiki, the free Doctor Who reference
SV39 was a Super-Voc originally created as a bereavement counsellor. It was sent to Volar Crick by Skellen after his wife's death to assist him and aid in the care of his children. It was programmed with words and phrases that his wife used with the aim of comforting him.
Crick used what he learnt from SV57 to nudge SV39 towards sentience. Without his knowing, this caused SV39 to think about its duties more creatively. It regularly accessed Jasdar's memory files to become her, believing that that would be the best way to assist the Cricks. Mentally unwell, Crick came to believe that SV39 was Jasdar.
