Like Randy I'm on my second go-round with RTM.  I'm also listening to X Minus One and was surprised to hear some of the same voices on there (but still fun listening to futures with steam powered space ships).  Anyway this episode was definitely good as I, like others, couldn't see where it was going to end and what Vincent's true role in the death of his mother may have been.  At the end at least we do know he did not suffer from an Oedipus Complex (in the usual understanding).
