I love Psychoville - it was my first introduction to their work - so this episode was a gift. Seeing David and Maureen back on screen was a massive treat. But yes, the new couple storyline felt a bit wasted. If anyone hasn't seen Psychoville and doesn't want to delve into both series, just watch Series 1, Episode 4. If I'm right, its actually where the idea of Inside No. 9 came from and its one of my favourite episodes of television ever.
