Character mistake: It is mentioned several times that the Larkins' holiday to France takes place in August. Whilst on the beach, Ma Larkin says that Mariette and Charlie's first wedding anniversary is the following week. However, it is established in the previous two part episode, 'When the Green Woods Laugh', that their wedding date is the seventh of July, the same date that Pop has to appear in court.
Other mistake: The court summons is delivered and states the case is to be heard on July 7th, which is the same date as Mariette's wedding. When the case starts, the charge is read to the court and states the date of the alleged assault of August 23rd, which would be 6 weeks in the future.
