When Logan is being sick in the field, the moped that he is collapsed next to keeps changing position in between shots. In some shots, Logan is right next to it, but in others, the moped is nowhere to be seen.
John and Nicki find an old newspaper clipping with John's dad's picture framed in a Brighton shop. They try to buy it with the shopkeeper not wanting to sell, but he tells them to get a copy from the newspaper office. They don't take note of the date on the paper, but instead go and try to find it just by John's dad's name. Not very likely for a small newspaper to have exact records of someone in a picture almost 40 years ago, but they might easily find it by the date.
Ad Geoff is called to come and help, he finds John sitting sideways on the Lambretta. It probably has taken a while, so why would John sit awkwardly on the profiled seat, when he is parked next to a perfectly good park bench?
John's Lambretta has a breakdown with Geoff coming to rescue. As they get it running, Geoff runs the revs up and down. He steps aside telling John he should be alright now and the revs still run up and down with no one turning the throttle.
