The description of an unnamed character that appears in the short story "Repercussions" by Gary Russell (in the Big Finish-published anthology Short Trips: Repercussions) resembles Sam. This character is a passenger on board an airship traveling through the time vortex that is carrying various people whom the Doctor had placed there to stop them from being a danger to the Web of Time. If that was Sam, it may indicate that, as far as the Big Finish continuity is concerned, she was written out of history.
