During the final scene in the flat, the door behind Raquel is open and after Del takes Damien to bed, the door is closed.
When Del Boy is singing in the street, Uncle Albert shouts from the balcony for him to come inside. The balcony door is open behind Uncle Albert on the left-hand side of the balcony. However inside the flat the door is on the opposite side and is also part of the window looking out into the estate.
When Delboy halts the riot to drive through to Nelson Mandela House, he blows the horn on the Capri in the middle of the steering wheel. The horn button on the Ford Capri was actually on the end of the indicator stalk.
Nick Ross is wearing a remembrance poppy in the episode of CrimeWatch that Raquel watches while ironing. As CrimeWatch is a live programme, this indicates it was from late October/early November and not around Christmas when this episode was set.
Del's answerphone message to Beverly is totally different to the one that is played back later on.
When Raquel is doing the ironing and waiting for Del to come back from the club, it is 10:20pm on a December evening; however the lightness and colour of the sky in the window behind her is more representative of a time of day much earlier in the evening and possibly even earlier in the year.
Del's dialogue in the market doesn't match the movement of his mouth- obviously a post production dubbing.
When Del approaches the bar to talk to Raquel on the phone, a camera is reflected in one of the photo frames.
After Del sings to start the riot and Rodney arrives at the flat, when Albert says he's not going to the window because a brick might come through, Rodney tells him they're on the 12th floor. But at the end of "A Royal Flush (1986)" when Rodney was yelling at Del, the floor number on top of the lift said "13th Floor".
Denzil tells Del, Mike, Boycie, and Trigger about how he has been split up from his wife Corrine for seven years (which would've placed the divorce in late 1986/early 1987), yet in "Danger UXD (1989)", Denzil was still together with his wife. Between the two episodes, the gap is less than seven years.
Rodney tells Cassandra that Del did not turn for his O-Level/GCE exams and got eight straight 'A's which stood for "Absent", yet in the second Rock & Chips (2010) episode, "Five Gold Rings (2010)", Del was shown to have left school before taking his GCE's. His family were fully aware of it, and they did not send Del back to school because he was their breadwinner.
