When Matt is looking through his door spyhole, it gives the first sight of his neighbour, "Dennis".
The character's prior mention had been in Palms, Pigs and Bad Debts (1998), where Matt mentioned the previously unheard-of neighbours, "Dennis and Ursula next door", with his finger pointing downwards, suggesting they live below. However, in this edition Dennis is seen walking down from above, with Matt observing that he's on his way to take a book back to the library.
