I know that episodes in each series are often swapped around. However this episode is clearly meant to be the opening episode but it's right in the middle of series 23. The episode opens with Nora getting into a taxi and then Clegg & Truly explaining she's in the sky. Also Tom is reminiscing about his father which to me indicate this would be a new series.
Not sure if others agree but for the first few episodes Nora's absence isn't really dealt with?
