Harry catches up with Geraldine and says 'I was just trying to get to grips with the village, mind if I string along?'. Ironically, although Geraldine is supposedly going home to get biscuits, she's actually walking the wrong direction, down the road away from her house and towards the church. She can't be on her way back as she is empty-handed.
Harry and Rosie sit on a bench supposedly part way through their walk. However they'd actually passed this distinctive seat at the start, left of the phone box. The bench is located on the right of the church gate, with Geraldine's house (and Sleepy Cottage) opposite on the left, as seen earlier in the episode when the vicar and Harry were going 'nowhere in particular'.
In the pub, Harry's cutlery changes position depending on the shot.
When Geraldine returns home after jumping in the puddle, her hair is wet but her clothes are dry.
When Harry 'strings along' with Geraldine, a white van outside the pub suddenly appears/disappears twice.
Geraldine has a Bible containing Dairy Milk bar above the fire place - the chocolate would melt in real life.
Geraldine uses a red pen to write the groom and bride's details in the record book. Black or blue is usually required for official documents and records.
