At 53.35, as Sophie goes into the cinema to see Charlie, a boy can be seen sat at a bus stop over the road looking across to see the filming.
At 53.24 it is twilight (clearly getting dark) when Dalziel and Pascoe give a second piece of bad news to Barron but, then, at 53.30, as Sophie goes into the cinema to see Charlie, it is broad daylight. The shot then goes back to Barron"s house.
