Katarina has made a return in Big Finish Productions, portrayed by Ajjaz Awad. In the series "Ravenous" story "Companion Piece", the kleptomaniac Time Lord known as the Nine attempts to retrieve Katarina's corpse to complete his latest 'collection' of the Doctor's companions, but when he attempts to read Katarina's mind to confirm her identity, the residual artron energy in her body leaves her consciousness 'active' enough for Katarina to distract the Nine so that other companions can defeat him. It is also revealed that Katarina's body had previously been retrieved by River Song, the Doctor's 'wife', who felt that Katarina deserved better than to be left behind like that even if River recognised that the Doctor had no choice.
