Oh, that was one of those unrelated-to-the-current-plots episode.
I like it. At first I was "ah?" when reading about Vic leaving the holosuite, but then I thought that he had some kind of portable emitter, not unlike the Doctors.
I was put off by Matthias's behaviour, though. She did understand her error in the end, but she treated Vic as a tool, a replicator, completely refusing to accept that he might possess independent thinking. What would she say about Data?
