Correction: "When Janet Met Jonny" at the end of series 3 was one of two "special" spin-off episodes that may well not be canon with the rest of the series. The other "special" episode was at the end of series 6, in which all the main characters died, yet they were all alive and well for series 7. If the events of "When Janet Met Jonny" were referenced in any other episode then this may be a valid mistake, but as it is, the episode can be considered non-canon.
